Running @answer.evaluators_for(:answer_reputation) in console

invokes

ReputationSystem::Evaluation Load (0.6ms)  SELECT "rs_evaluations".* FROM "rs_evaluations" WHERE "rs_evaluations"."target_id" = 131 AND "rs_evaluations"."target_type" = 'Answer' AND "rs_evaluations"."reputation_name" = 'answer_reputation'

It returns Evaluations not evaluators (in my case 'users') as opposed to the wiki.

I am trying to have AdminUsers able to vote on Items. My two models are configured as follows:

Item.rb
has_reputation :votes, source: :admin_user, aggregated_by: :sum

AdminUser.rb
has_reputation :votes, source: {reputation: :votes, of: :items}, aggregated_by: :sum

Everything works unless I include the association in AdminUser.rb which raises the following error. The vote still gets saved because when I refresh the page the vote appears fine. Any guidance appreciated. Thanks!!

Hi ! I'm using this gem, thank you !
Is it possible to do any action automatically before or after evaluation ? Like before_save or after_validation for an ActiveRecord.

Thank you

reptuation_for should be reputation_for :)

I'm trying to order a big array by reputation using the ActiveRecordReputation gem.

Is it possible?

I have a model call Microposts, It has a reputation system called :votes.

Those microposts belongs to other model call Group and a User have many groups.

I need to get all the microposts of the groups that the User is suscribe and order it by reputation.

I get a big array of microposts like this:

@microposts = Micropost.joins(:group => :users).where(:users => {id: current_user.id})
But it stil missing the reputation order.

I hope you can help me!

Hi,
I'm trying to use this gem for assigning "points" for records created inside a CMS. Please let me know if these types of work is possible using this gem.

The CMS is for recording "job" entries for company "Employees" - a Job belongs to a "Category" and Category has a "score" attribute associated. Job entries are created by CMS Managers. All I need is when a Manager create job entry (which belongs to a Category of course), I need to assign relevant score to the "Employee"

Finally I need to Calculate the average score each employee scored comparing to the other employees by Category.

Does this make any sense?

Cheers!

Is there a method to recalculate reputation for a given object?
I've been having issues with STI support (add_or_update_evaluation was previously updating the subclass reputation, while reputation_for is now returning the base class reputation or something else), but anyway, I now have two reputations for every STI object: one for the subclass, one for the base class, and they're both inaccurate, so I need to recalculate reputations somehow. I haven't found anything in the API, both public and private.
Also, STI behavior seems inconsistent: previously it wasn't using the base STI class at all, now it uses the base class for reputations, while still using the subclass name for evaluations.

I have the follows entity:

class App < ActiveRecord::Base
  # Rating
  has_reputation :rating, source: :user, aggregated_by: :average
end

and

class User < ActivieRecord::Base
end

How can I get the user's rating value for certain app?

Hi,

I ran into a problem when using this gem in the case that the source of a evalution uses STI. I'm also able to reproduce it in a new app.

Let's say we have the following models with the configured reputation system:

class User < ActiveRecord::Base
  has_many :posts
end

class Student < User
end

class Professor < User
end

class Post < ActiveRecord::Base
  belongs_to :user

  has_reputation :votes, source: :user, aggregated_by: :sum
end

When I'm now adding a evalutation with a student object as source post.add_or_update_evaluation(:votes, 1, student) this Evalutation is stored:

#<ReputationSystem::Evaluation id: 5, reputation_name: "votes", source_id: 2, source_type: "User", target_id: 1, target_type: "Post", value: 1.0, created_at: "2012-11-28 10:42:40", updated_at: "2012-11-28 10:42:40">

As you already see it, uses the base class User to store Evaluation.
If I want to update the Evaluation now with post.add_or_update_evaluation(:votes, -1, student).

I get this:

ReputationSystem::Evaluation Load (0.6ms)  SELECT "rs_evaluations".* FROM "rs_evaluations" WHERE "rs_evaluations"."reputation_name" = 'votes' AND "rs_evaluations"."source_id" = 2 AND "rs_evaluations"."source_type" = 'User' AND "rs_evaluations"."target_id" = 1 AND "rs_evaluations"."target_type" = 'Post' LIMIT 1

  from (irb):39

Following the backtrace the problem is in add_or_update_evaluation, the check if a evaluation from this source already exists. Somehow it uses in this case not like in every other case the base class, it uses the class of the object, in this case Student. So it doesn't find the existing evalution and tries to create a new one which fails.

Do you have any hints to fix this problem?

Thanks, André

First off, this is how my models (the relevant parts) are defined:

class User < ActiveRecord::Base
  has_many :comments, dependent: :destroy
  has_reputation :comments,
                 source: { reputation: :comments, of: :comments }
end

class Comment < ActiveRecord::Base
  belongs_to :user
  has_reputation :comments,
                 source: :user,
                 source_of: { reputation: :comments, of: :user }
end

I don't have any problem with adding any other reputations. However, when adding this particular one, I see the following error in both my rails console and when starting the rails server:

Any ideas or suggestions would be greatly appreciated.

Everything was running great in rails 3.0.8. I am upgrading to rails 3.2 eventually but to get things ready Ryan Bates in a Railscast recommended that I upgrade to rails 3.0.17 first. After upgrading to 3.0.17 I got "undefined method `reputation_value_for' for #<User: foo>".

I am running rails in a rvm installed Ruby version 1.9.2. To be sure that it wasn't a problem with gems, I uninstalled 1.9.2 and reinstalled it. I installed the bundler gem and then ran bundle install. It still got the same error.

I then renamed the database migrations and ran rails g reputation_system. The old and new migration files were exactly the same.

Hi, I'm trying to build a reputation system with positive and negative votes, but I would like to know, what was the last evaluation of a user?

If the user gives a positive or negative vote to know wich kind of icon I must show.

How can I do that?

So, my setup is very simple. I got the User model with the following:

  has_reputation :score, source: :parking_ticket ,aggregated_by: :sum

First I execute

  user.add_evaluation(:score, 15, partking_ticket)

and when I execute

   user.evaluators_for(:score)

it returns me all the parking_ticket, OK. But how can I return how much each parking ticket evaluated (the 15 on the example)?

Is there a support for unvoting? I wanted to be able to retract votes. Thanks.

Is there a way to unvote a reputation?

I get the following error undefined method first_page?' for #Array:0x007fb2fa6dc3b0using thepaginate` method of Kaminari in the view.

Note: I am following http://railscasts.com/episodes/364-active-record-reputation-system for this example.

I have a Location model where I am letting the user rank (i.e. 1 to 5 stars) the item:

has_reputation :location_rating, source: :user, aggregated_by: :average

In my controller I am either deleting the rating:

@location.delete_evaluation(:location_rating, current_user)

or updating it:

@location.add_or_update_evaluation(:location_rating, params[:rating] , current_user)

I am brutally confused how to query:

• the current average rating of a Location by all users
• the rating of a given Location by a given user
• the count of ratings on a given Location

I am trying @location.reputation_for(:location_rating) and getting some weird behavior. If a given user deletes a rating and then the new reputation_for value seems to averaging in the old ratings.

For example:

1.9.3p0 :038 > RSEvaluation.all RSEvaluation Load (1.7ms) SELECT "rs_evaluations".* FROM "rs_evaluations" +----+-----------------+-----------+-------------+-----------+-------------+-------+-------------------------+-------------------------+ | id | reputation_name | source_id | source_type | target_id | target_type | value | created_at | updated_at | +----+-----------------+-----------+-------------+-----------+-------------+-------+-------------------------+-------------------------+ | 46 | tracking | 1 | User | 6 | Location | 0.0 | 2012-08-28 05:15:13 UTC | 2012-08-28 05:15:13 UTC | | 48 | tracking | 1 | User | 5 | Location | 0.0 | 2012-09-04 14:44:37 UTC | 2012-09-04 14:44:37 UTC | | 51 | tracking | 1 | User | 8 | Location | 0.0 | 2012-09-12 06:51:58 UTC | 2012-09-12 06:51:58 UTC | | 52 | tracking | 1 | User | 1 | Location | 0.0 | 2012-09-12 14:54:39 UTC | 2012-09-12 14:54:39 UTC | | 54 | location_rating | 1 | User | 5 | Location | 3.0 | 2012-09-19 05:10:46 UTC | 2012-09-19 05:18:16 UTC | | 56 | tracking | 11 | User | 5 | Location | 0.0 | 2012-09-19 05:47:10 UTC | 2012-09-19 05:47:10 UTC | | 58 | location_rating | 11 | User | 3 | Location | 2.0 | 2012-09-19 06:33:12 UTC | 2012-09-19 06:33:12 UTC | | 61 | location_rating | 11 | User | 5 | Location | 5.0 | 2012-09-19 07:15:42 UTC | 2012-09-19 07:15:42 UTC | +----+-----------------+-----------+-------------+-----------+-------------+-------+-------------------------+-------------------------+

On Location id = 5 should my reputation not be (3 + 5) / 2 = 4? I currently get 2.59375. I update User 11's rating to 1 and the new reputation is 0.59375.

I am sure I am missing something obvious here (newbie).

Hi,

Does this method work with Rails 4 yet?

This is my gem file:
gem 'activerecord-reputation-system', github: 'NARKOZ/activerecord-reputation-system', branch: 'rails4'

When I try this in my controller nothing gets ordered:

find_with_reputation(:votes, :all, :order => "votes desc")

Thanks

Hello,

my issue is that after starting my local server in production mode the reputation system stops working correctly, current_user.reputation_for(:votes).to_i returns 0. When running in development mode everything works fine. In my case I have two sources of repution on the user model, it looks like this

user.rb

has_many :posts
has_many :comments

has_reputation :votes, :source => [{ :reputation => :comment_votes, :of => :comments },{ :reputation => :post_votes, :of => :posts}]

post.rb

has_many :comments
belongs_to :user

has_reputation :post_votes, source: :user

comment.rb

belongs_to :post
belongs_to :user

has_reputation :comment_votes, source: :user

Do you have any idea why this may be?

ERROR: Could not find a valid gem 'reputation_system' (>= 0) in any repository

Are you using a non-standard repo?

Given the example model:

class Question < ActiveRecord::Base
  belongs_to :author, class_name: 'User'
end

How would be the correct way to define a reputation where the author/User is the source?

has_reputation :votes, 
  source: :author, 
  aggregated_by: :sum

Gives a ActiveRecord::RecordInvalid: Validation failed: Source type User is not source of votes reputation for a.add_evaluation :votes, 1, current_user for example.

and

has_reputation :votes, 
  source: :user, 
  aggregated_by: :sum

Gives a NameError: undefined local variable or method 'user' on an instance of Question. for a.add_evaluation :votes, 1, current_user

Suppose I have User and Article classes associated like this:

class User < ActiveRecord::Base
  has_many :articles
end

class Article < ActiveRecord::Base
  belongs_to :user
end

and want to track the following reputations:

1. Average evaluation of an article
2. Average evaluation of a user's articles scoped per-source-user (i.e. for given u1 and u2, the average of all evaluations by u1 of u2's articles)
3. Globally averaged user reputation (i.e. the average of the averaged reputations from 2.)

Is there a way to implement the 2nd and 3rd types of reputation with this gem?

This is also a SO post: http://stackoverflow.com/questions/18246904/twitter-activerecord-reputation-counting-primary-reputations-as-non-primary-rep

I have two models: Voters and Polls.

A Voter can vote on a Poll in two ways: 1) up/down vote 2) power vote

I have up/down voting working, but I want to be able to know how many power votes a user has accumulated in aggregate as they can only have a certain amount.

poll.rb

class Poll < ActiveRecord::Base
  belongs_to :voter

  has_reputation :votes,
                 source: :voter

  has_reputation :powervotes,
             source: :voter,
             source_of: [{reputation: :voter_powervotes, of: :voter}]

  has_reputation :score,
                 source: [
                   { reputation: :votes },
                   { reputation: :powervotes, weight: 2 }]

  def upvote(voter)
    self.add_or_update_evaluation(:votes, 1, voter)
  end

  def downvote(voter)
    self.add_or_update_evaluation(:votes, -1, voter)
  end

  def powervote(voter)
    self.add_or_update_evaluation(:powervotes, 1, voter)
  end

  def score
    self.reputation_for(:score).to_i
  end
end

voter.rb

class Voter < ActiveRecord::Base
  has_many :polls

  has_reputation :voter_powervotes,
             source: [reputation: :powervotes, of: :polls]

  def powervotes
    self.reputation_for(:powervotes).to_i
  end
end

When I powervote() on a poll as a voter and then call Voter.powervotes it returns 0. I think this is because of STI.

Assuming Voter ID 1 and Poll ID 1, when I record a powervote as a user on a poll, using this setup, 3 reputations are created in my rs_reputations table.

powervotes
voter_powervotes
score

Everything seems fine, until you dig a little deeper: voter_powervotes' target_id seems to be pulling the wrong ID. In this case it's pulling 4 - it should be 1. I think it's doing this because Poll ID 1 has a column called voter_id and its value is 4. I don't care about who the Poll belongs to I just care about each user's powervote count.

Is there a better way to setup the associations between models or have I found a bug?

I've based some code closely off the readme's example:

has_reputation :karma,
  :source => [
   { :reputation => :comment_popularity },
   { :reputation => :impression_total }],
:aggregated_by => :sum

has_reputation :impression_total,
  :source => { :reputation => :points, :of => :impressions },
  :aggregated_by => :sum

has_reputation :comment_popularity,
  :source => { :reputation => :votes, :of => :comments },
  :aggregated_by => :sum

In my view, I get the results I expect if I display the :impression_total or :comment_popularity like so:

<%= user.reputation_value_for(:impression_total).to_i %>

However, if I try to display :karma, I only get "0"--even if the sum of :impression_total and :comment_popularity should be "15" or "21" or some other number. What might I be doing wrong here?

In Browser:
Getting an "undefined method has_reputation" ... This error occurred while loading the following files: /Users/username/appname/config/routes.rb ... config/routes.rb:6:in `block in <top (required)>'

SOLUTION: Require 'reputation_system' in Gemfile:

gem 'activerecord-reputation-system', :require => 'reputation_system'

Hi,

I get this error when I try to delete an evaluation, here is my configuration, I have two model User, Article described as below. This error happens when I invoke

@article.delete_evaluation(:votes, @user)

Here is the article model

class Article < ActiveRecord::Base
  belongs_to :contributor, class_name: 'User'
  has_reputation :votes, source: :user, aggregated_by: :sum, source_of: [{reputation: :writing_skill, of: :contributor }]
end

Here is the User model

class User < ActiveRecord::Base
  has_many :articles, dependent: :destroy, foreign_key: :contributor_id
  has_reputation :writing_skill, source: {reputation: :votes, of: :articles }, aggregated_by: :sum
end

I think this because of the dependent destroy of RSReputationMessage on destroy of RSEvaluation . There is also a dependency on the destroy of RSReputationMessage to destroy RSEvaluation, which results in this error.

I have this in my User model

has_many :evaluations, class_name: "RSEvaluation", as: :source
has_many :questions
has_many :answers

has_reputation :karma,
:source => [
{ :reputation => :questioning_skill },
{ :reputation => :answering_skill } ]

has_reputation :questioning_skill,
:source => { :reputation => :votes, :of => :questions }

has_reputation :answering_skill,
:source => { :reputation => :votes, :of => :answers }

But whenever I user.reputation_for(:karma) I always get 0.0.
No problem with user.reputation_for(:questioning_skill) because I get the correct value.

What if I have a list of links and wanted to check if a user vote for it or not, I dont want to call over 30 SQL calls if i have listed 30 links!

I have a weird issue and I'm not sure what is causing it.

I have an aggregated reputation called "karma" that is the sum of 3 other reputations

  has_reputation :karma,
  :source => [
      { :reputation => :comment_votes },
      { :reputation => :review_votes },
      { :reputation => :status_votes }],
  :aggregated_by => :sum

  has_reputation :comment_votes,
  :source => { :reputation => :votes, :of => :comments }

  has_reputation :review_votes,
  :source => { :reputation => :votes, :of => :reviews }

  has_reputation :status_votes,
  :source => { :reputation => :votes, :of => :statuses }

In my status model

has_reputation :votes, :source => :user, :aggregated_by => :sum, :source_of => [{ :reputation => :status_votes, :of => :user }]

This reputation setup seems to be working on most of my test users but for one user, the value for karma is 0 even if the user has a non-zero value for :status_votes. user.reputation_for(:status_votes) would return 4 but user.reputation_for(:karma) would be 0. What could be causing this problem?

EDIT: I've noticed that in general Karma is not the sum of the 3 reputation systems. Is my setup wrong?

This would greatly improve the flexibility of the available 'process' options!

Thanks for the great gem!

SHORTENED FOR BREVITY:
Basically, this error can occur if the reputation model is defined using invalid syntax...

HOWEVER,
It can also apparently occur when syntax is kosher according to the Github docs.

Simplest Setup, almost, but doesn't run. I want to create a feedback section for my Spree Shop. Feedback entries shall by up- or downvoted by people.

class Feedback < ActiveRecord::Base ("requires spree/user")

belongs_to :user # from Spree Commerce Engine / Devise

has_reputation :votes, source: :user, aggregated_by: :sum

Decorator for Spree::User : ("requires Feedback")

has_many :feedbacks

has_reputation :votes, source: {reputation: :votes, of: :feedbacks}, aggregated_by: :sum # I do not exactly know if this line is necessary in my case, but outcommenting does not change anything

Controller method "vote" :

value = params[:type] == "up" ? 1 : -1
feedback = Feedback.find(params[:id])
feedback.add_or_update_evaluation(:votes, value, current_user)

FAILS with:

(0.1ms) rollback transaction

I strongly suspect source_type ActiveRecord::Base to be a problem, but cannot tell exactly, unfortunately. Inspecting the bare associations works flawlessly.

Other theory is, that the module loading order somehow breaks it.

Any ideas and help appreciated

This issue is related to but different from an earlier issue.

I have a Post model with many Comments. Each comment has a reputation. At the moment, when I load a page, the database is queried for each comment's reputation. I tried eager loading the conventional way:

Comment.includes(:rs_reputation).where(:post_id => self.id)

Unfortunately, this throws the error:

Association named 'rs_reputation' was not found; perhaps you misspelled it?

I get the same error when I pluralize it to "rs_reputations." How else could I eager load the comment reputations?

I'm trying to copy the karma reputation system demonstrated on this page https://github.com/twitter/activerecord-reputation-system but it's not totalling the component values. <%= @user.reputation_for(:karma).to_i %> is showing '0' when it should be 11 for my test user.

Code

<%= @user.reputation_for(:votes).to_i %> #showing as '1' for the test user
<%= @user.reputation_for(:best).to_i %> #showing as '10' for the test user

<%= @user.reputation_for(:karma).to_i %> #should be showing as '11' for the test user but is zero

I created a reputation system a couple months ago and it was working fine. With the latest update, it's broken. I've been working on the site (though not the reputation system specifically), so the break might be because of something I've done, though I can't figure out what. Anyway, here's what going on now:

I have this line of code in my Impressions class:

@impression.add_evaluation(:points, 1, current_user)

Which throws this error:

votes is not defined for NilClass

"votes" is the name of a reputation belonging to the Comments class. There seems to be some sort of cross-over here.

For reference, here's the relevant snippets of code. The method that's throwing the error:

def create
  @impression=Impression.new(params[:impression])
  @impression.save
  @impression.add_evaluation(:points, 1, current_user)
end

The definition for "points" in the Impressions model:

has_reputation :points, source: :user, aggregated_by: :sum,
:source_of => [{ :reputation => :whuffie, :of => :user }]

The definition for "votes" in the Comments model:

has_reputation :votes,
:source => :user,
:aggregated_by => :sum,
:source_of => [{ :reputation => :whuffie, :of => :user }]

UPDATE:

The problem only appears if a user has not yet received any comments. Once the user has received a comment, then the code works as it should.

Hi ,
When I am using RSEvaluation in user module it throwing error .

has_many :evaluations, :class_name: "RSEvaluation", as: :target .

In console also throwing error when i call RSEvaluation.all

Thanks in Advance,
Ptrasad.

Hi, I have a serious problem with my app, I have a Model call Microposts that have a reputation system call "ups".
Micropost.rb
has_reputation :ups, source: :user, aggregated_by: :sum

User.rb
has_reputation :ups, source: {reputation: :ups, of: :microposts}, aggregated_by: :sum

I have follow the railscast for this gem and I have defined the method of the post request like this:

<%= link_to "xxx", vote_micropost_path(micropost, type: "up"), method: "post", class: "trick_anchor" %>

<%= pluralize micropost.reputation_for(:ups).to_i, "vote" %>

<%= link_to "xxx", vote_micropost_path(micropost, type: "down"), method: "post", class: "trick_anchor" %>

In the controller I have refined my method:

def vote
value = params[:type] == "up" ? 1 : -1
@Micropost = Micropost.find(params[:id])
@x = @micropost.reputation_for(:ups).to_i
@value = @x + (value)
logger.debug "Voto despues: #{@value}"
@micropost.add_or_update_evaluation(:ups, @value, current_user)
end

It seems that it must work, but in the console it show a different result.

How can I update the reputation of a Micropost?

Hello. Thanks for the great gem.
For some reason, user.reputation_for(:votes).to_i works fine in development, but returns only 0 once deployed to production(Heroku). At the same time, link.reputation_for(:votes).to_i works in both development and production.
I seem to have similar symptoms to issue#13, but in my case, it's just a single sum calculation, and restarting/redeploying has not fixed the problem.
Do you have any idea why this may be?

link.rb
has_reputation :votes, :source => :user, :aggregated_by => :sum

user.rb
has_reputation :votes, :source => { :reputation => :votes, :of => :links }, :aggregated_by => :sum

Are there any plans to use strong parameters instead of attr_accessible?

Version 1.1.0 isn't tagged in the repo.

Hi, first I just want to thank you for all the hard work you're doing and have done in creating and supporting this gem.

I have a question that's almost exactly the same as this one.

In the aforementioned issue, you explained that this:

@comment = Comment.find_with_reputation(:reputation_name, :all)

would allow you to access the reputation value like this:

@comment.comment_votes

without additional DB queries.

You said that code like this:

Comment.includes(:reputations)

would not give you the same ability to access the reputation value without another query.

Like the author of the previous issue, I want to eagerly load reputation value, but in my case I want to do so inside of a nested eager loading hash.

My unoptimized code looks like this:

@article = Article.find(1)
@comments = @article.comments.find_with_reputation(:votes, :all, :order => 'votes desc', :limit => 20)

I want to write something with eager loading like this:

@article = Article.includes(comments: :comment_votes).find(1)

and then be able to access comments[0].comment_votes.

So my question is: Is there anyway to eagerly load comment_votes in the way that find_with_reputation does inside of a nested eager loading hash (i.e. Article.includes(comments: :comment_votes) )?

And if there is a way, is it also possible to include conditions on the comments?

Sorry if this is a silly question, as I'm pretty new to Rails, and thanks for any help!

When I combine STI and reputation-system gem, I need do some tricks. Here is the code.

  class Tile < ActiveRecord::Base; 
    has_reputation :likes, :source => :user, :aggregated_by => :sum 
  end
  class ObservationTile < Tile; end
  class ActionTile < Tile; end

   # run code
   @action_tile.add_evaluation(:likes, 1, current_user) 
   # => Error with no likes reputation for ActionTile

After checking the source code, I found the problem is on ReputationSystem::Network, most methods on ReputationSystem::Network relies on class_name. But the STI subclass has different class_name from it's super class.
So one solution is like this

  class Tile < ActiveRecord::Base;   end
  class ObservationTile < Tile; 
    has_reputation :likes, :source => :user, :aggregated_by => :sum 
  end
  class ActionTile < Tile; 
    has_reputation :likes, :source => :user, :aggregated_by => :sum 
  end

That's not what I need, cause I want the value on column target_type of RSEvaluation stick on "Tile".
So I need override the add_evaluation like this

 # file tile.rb
 alias_method :original_add_evaluation, :add_evaluation
 def add_evaluation(*args)
   becomes(Tile).original_add_evaluation(*args)
 end

And a final result is

  class Tile < ActiveRecord::Base; 
    has_reputation :likes, :source => :user, :aggregated_by => :sum 

    %w[add_evaluation delete_evaluation delete_evaluation!].each do |name|
      alias_method ":original_#{name}", name

      define_method name do |*args|
        becomes(Tile).send ":original_#{name}", *args
      end
    end
  end
  class ObservationTile < Tile; end
  class ActionTile < Tile; end

It's not a bug. I just want to know which one is better.

I have a Comments class which is votable. I want to display which users have voted for a given comment, and whether their vote was positive or negative. Unfortunately, I can't figure out how to access that information. Looking at the migration file, it seems like the "source" attribute is the best bet. However, when I call on "source," I seem to get the Users class, rather than specific users. Any advice?

Following first install, and config per the README, I get:

ActionController::RoutingError - undefined method `has_repuation' for #<Class:0x000001048ed758>:

when calling Controller#index for the following model:

class Link < ActiveRecord::Base
  belongs_to :node

  has_reputation :avg_rating,
      :source => :user,
      :aggregated_by => :average

  has_reputation :views,
      :source => :user,
      :aggregated_by => :sum

  has_repuation :karma,
      :source => [{ :reputation => :avg_rating },
                  { :reputation => :views }],
      :aggregated_by => :product,
      :source_of => [{ :reputation => :karma, :of => :user }, 
                     { :reputation => :karma, :of => :node }]

gem version 2.0.2
(adding ":require => 'reputation_system' " did not change the error)

Any suggestions?

Also, is the reputation system generated at server load? Or is it necessary to rails g reputation_system & db:migrate upon each change of the code?

I'm hitting what seems to be an internal error within Active Record. I'm running rails 3.2.13, with activerecord-reputation-system 2.0.2. I get an undefined method '+' in this section of code at code called at line 117. I'm not sure what's causing this problem and am hoping for a little help as the trace seems to point to something in active record. The code that calls this is below.

[If there's any additional info needed to help solve this, please just let me know.]

  112     solution = Solution.find(@temprating.solution_id)
  113     p "solution is #{solution}"
  114     admin = User.find(6)
  115     if solution.has_evaluation?(:kudos, admin)
  116       p "temprating is #{@temprating.rating}"
  117       solution.increase_evaluation(:kudos, @temprating.rating, admin)
  118     else
  119       solution.add_evaluation(:kudos, temp, admin)
  120     end

From Beter Error's panel, I can see what the instance variables values are all decidedly not nil. I'm not including the admin user, but it's another regular user record.

#<TempRating id: 13, solution_id: 1944, email: "[email protected]", rating: 1, verified: true, created_at: "2013-04-18 22:50:48", updated_at: "2013-04-18 22:51:42", token: "censored">

#<Solution id: 1944, user_id: 1314, contest_id: 84, title: nil, keyword: nil, summary: "Derp", created_at: "2013-04-12 19:28:01", updated_at: "2013-04-12 19:28:01", rating: -1, comment: nil, winning_status: 0, payment_option: 0>

This line from the solution model defines the reputation system.

has_reputation :kudos, :source => :user, 
    :source_of => {:reputation => :received_kudos, :of => :user}

It causes this stack trace, where the first two lines here are the print statements from the controller.

It could be great to be able to use creation date of an object as a source to do something like the Hacker News home page. Here are the classical formulas : http://www.seomoz.org/blog/reddit-stumbleupon-delicious-and-hacker-news-algorithms-exposed
