active-orient's Issues

undefined method `default_server=' for ActiveOrient::OrientDB:Class

I am using the test_commands.rb file in the examples folder as a standalone ruby script. I have the OrientDB server running locally. When I rub the script I get this error: undefined method `default_server=' for ActiveOrient::OrientDB:Class (NoMethodError).

I thought of removing OrientDB from the line. Now I get this error:

   I, [2017-05-10T12:10:48.634338 #31412]  INFO -- OrientDB#Connect: Connected to database NewTest
   /home/user/.bundle/ruby/2.3.0/active-orient-fdae334715ca/lib/class_utils.rb:44:in `allocate_class_in_ruby': undefined method `const_defined?' for nil:NilClass (NoMethodError)

           from test_commands.rb:8:in `new'
           from test_commands.rb:8:in `<main>'

Am I missing something or is this an issue?

Queries with "like" and "matches" Operators don't work

If a Query is build and transmitted, it fails if a "%" is used in the command:
linked_element = @new_record.ll.where( "att like '3%'" )
fails with
RestClient::HTTPVersionNotSupported:
505 HTTP Version Not Supported

The matches operator is not working in OrientDB 2.1+2.2

See spec/array-spec.rb

"get one element from the embedded array by condition"

Cannot create the classes

I am on Ruby 2.4 and OrientDB 2.2.14 (+ Rails 5.0). I can't seem to initiate the database in a way that it can create the database classes in Ruby. I have also tried installing the gem from Github as well, to no avail.

I run the following:

require 'bundler/setup'
require 'active-orient'
require 'logger'

load 'helpers.rb'

logger = Logger.new '/dev/stdout'
ActiveOrient::Model.logger = logger
ActiveOrient::OrientDB.logger = logger
ActiveOrient.default_server = {server: 'localhost', user: 'root', password: 'xxx', database: 'gems', port: 2480}

@g = ActiveOrient::OrientDB.new database: 'gems'

Upon the execution, I receive:

The log continues with more errors similar to this one.

The database object seems to initialize successfully, but create_class won't work.

ActiveModel

It seems that you have a hard dependency on activemodel but don't list it in the gemspec?
Your example in the README doesn't work as is.

Unless I'm missing something. Had to add 'activemodel' gem as well

Thanks.

Trying to use active-orient with Rails 6

I am stuck at this error when trying to use active-orient with Rails 6.

RID-Cache needs Garbage Collection

Every dataset transfered from the database is stored in a rid-store, simply an array.
Any allocated ruby object refers to that and is thus updated automatically.

We have to implement a mechanism to shrink the array from time to time.

OO-Behavior of Edges

Edges are automatically translated into methods/attributes aka: (in)(out)_(classname)
These attributes just reflect the morphology of the database.

To reveal their oo-behavior a query has to send: select (in)(out)E('classname') form class

Some metaprogramming is required to automatically build a method record.classname which gives any edge with respect to the oo-tree.

Problem is: normally not the edge is queried, its the vertex connected to it.
Thus active-record: "has_many :through " has to be redefined

Some questions

I try some of the examples in your readme files and in your repository and I had some problems that I am not able to solve. To install your gem I used gem install active-orient
Here a short list.

I use your commands to create these Vertexes and Edges:

require 'bundler/setup'
require 'active-orient'

ActiveOrient::OrientDB.default_server= { user: 'root', password: 'password' }
r = ActiveOrient::OrientDB.new database: 'First'

Vertex = r.create_vertex_class 'd1'
Edge = r.create_edge_class   'e1' # <--- Note, here I changed your Eedge in Edge

start =  Vertex.create  something: 'nice'
the_end   =  Vertex.create  something: 'not_nice'
the_edge = Edge.create_edge  attributes:  { transform_to: 'very bad' },
                 from: start,
                 to: the_end

print start.e1[0]

The vertex and edge are created, but when I want to print the result I receive:

I, [2016-03-16T10:13:44.185332 #1229]  INFO -- OrientDB#Connect: Connected to database First
D, [2016-03-16T10:13:51.499534 #1229] DEBUG -- ActiveOrient::OrientDB#NexusEdge: creating edge E1 from #13:0 to #13:1
testActiveOrient.rb:76:in `<main>': undefined method `[]' for nil:NilClass (NoMethodError)

I tried to use the Query command at the end of the readme file.
This is my code:

require 'bundler/setup'
require 'active-orient'
ActiveOrient::OrientDB.default_server= { user: 'root', password: 'password' }
r = ActiveOrient::OrientDB.new database: 'First'`
ach = ActiveOrient::Query.new

   ach.queries << 'create class Contracts ABSTRACT'
   ach.queries << 'create property Contracts.subcategory link'
   ach.queries << 'create property Contracts.details link'
   ach.queries << 'create class Stocks extends Contracts'
   ach.queries << 'create class Futures extends Contracts'
   result = ach.execute_queries transaction: false

print result

but the only result is the following:

I, [2016-03-16T10:22:40.414749 #1304]  INFO -- OrientDB#Connect: Connected to database First 
testActiveOrient.rb:78:in `<main>': uninitialized constant ActiveOrient::Query (NameError)

In the file "street.rb" in the folder examples, I think that the German website has changed its css. For this reason I suggest to change this:
strassen = doc.css('#strassen-in-deutschland_main a' )
in this:
strassen = doc.css("td[data-header='Straßenname: '] a")

rspec failed.

I cloned repo and execute bundle install and rewrote config/connect.yml .
But I failed rspec.
Can I work well ?

undefined method `progname=' for nil:NilClass (NoMethodError)

I'm getting error messages like below when a new vertex of class AirPort is created. As you see below I'm creating two vertices NY and LA. I have noticed that first vertex would however created in the database, but after it throws an error, second vertex LA would not be created. Any help is greatly appreciated.

Issues with JRuby

Hii @topofocus

Hey, I'm trying out this package with jruby - it works fine on the mri

I installed the active-orient and active-model gems via

> jruby -S gem install active-orient
> jruby -S gem install activemodel -v 4.2.6

But when I try to do a simple ActiveOrient::OrientDB.new database: 'GamesOfThrones' in the jirb it gives the following error TypeError: no implicit conversion of nil into Hash

Stack trace is as follows

TypeError: no implicit conversion of nil into Hash
	from org/jruby/RubyHash.java:1708:in `merge!'
	from org/jruby/RubyHash.java:1744:in `merge'
	from /Users/eklavya/.jruby/lib/ruby/gems/shared/gems/active-orient-0.42/lib/rest.rb:50:in `initialize'

	from org/jruby/RubyKernel.java:1115:in `catch'
	from /Users/eklavya/.jruby/bin//jirb:13:in `<main>'

Is there a solution to this ?

Few thoughts after reading the README

First of all - it's great to see a gem supporting OrientDB!

How about naming it rest-orient? There is not that much ActiveRecord pattern there yet.
I would also suggest using RESTOrient or similar namespace instead of a more general REST namespace:

RESTOrient::Model
RESTOrient.orientdb = RESTOrient::OrientDB.new

Is there # missing here?

  r.get_document '21:1'

Uninitialized constant error on require "active-model"

Hi again @topofocus

Hey, last night I installed Rails 5.0.0.1 and after that when I tried using the active-model gem, the repl throws the following error.

pry(main)> require 'active-orient'
NameError: uninitialized constant ActiveModel::Serializers::Xml
from /Users/eklavya/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/active-orient-0.42/lib/base.rb:10:in `<class:Base>'

I did google around and came across rails/rails#24558 apparently ActiveModel::Serializers::Xml has been removed from Rails5 but how dose all that related to active-orient is beyond me.

I've already tried installing

gem 'activemodel-serializers-xml'
gem 'active_model_serializers'

but that doesn't seem to solve the problem. Do you have any suggestions?

Connect to OrientDB Distributed Architecture

Currently active-orient picks server details from a connect.yml file.
The following lines takes the config in the activeorient.rb file.

username = eval(connectyml[:user])
password = eval(connectyml[:pass])
server = eval(serveryml[:server])
port = eval(serveryml[:port])

However I have setup OrientDB in a distributed mode. Is there a way active-orient can communicate with all the nodes in the distributed configuration?
