Hi, are you using the rails framework? then please follow the steps described in rails.md. (important: copy activeorient.rb to initializers ... there anything is initialized ) otherwise... change to config/config.yml, insert your database credentials and turn to bin/active-orient-console if you still need assistance, call me via google-hangouts ( [email protected]) Then y Grüße Hartmut Bischoff 2017-02-10 16:11 GMT+01:00 Mahmood S.

I am on Ruby 2.4 and OrientDB 2.2.14 (+ Rails 5.0). I can't seem to even initiate a database. I have also tried installing the gem from Github. 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: E, [2017-02-10T16:06:17.330945 #89252] ERROR -- ModelClass#OrientDBClass: ModelClass "_v" cannot be initialized.

Thanks for the prompt response!

I am simply trying to use it as a gem in a standalone script. It used to be possible before (when I wrote the code) to do so. Is that no possible anymore? Do I necessarily need to clone the project, update the database connection info in the YAML file and add my scripts to the project?

By the way, I am trying to run the version 0.6.

Not necessarily.

look to config/boot.rb

these are the essential steps

63 ActiveOrient.default_server= { user: connectyml[:user], password: connectyml[:pass] ,
64 server: 'localhost', port: 2480 }
65 ActiveOrient.database = @configDatabase.presence || databaseyml[env.to_sym]
66
67 ORD = ActiveOrient::OrientDB.new preallocate: @do_not_preallocate.present? ? false : true
68 if RUBY_PLATFORM == 'java'
69 DB = ActiveOrient::API.new preallocate: false
70 else
71 DB = ORD
72 end
73 # ActiveOrient::Init.vertex_and_edge_class
74
75 ORD.create_classes 'E', 'V'
76 E.ref_name = 'E'
77 V.ref_name = 'V'
78 # require model files after initializing the database
79 require "#{project_root}/lib/model/edge.rb"
80 require "#{project_root}/lib/model/vertex.rb"

The database is stored in »ActiveOrient.database«
It's opened via » ActiveOrient::OrientDB.new preallocate: true «
And please initiate «ActiveOrient.default_server» as well.

The edge- and vertex-model-file extensions are useful.

If you are familiar with rails, the approach to autoload model-files should comfort you.
please take a look at https://github.com/topofocus/orientdb_time_graph. If you clone it, it might act as a sample-project using the ActiveOrient gem.

I found the problem. The current version does not accept the following (the help file says it should):

ActiveOrient::Init.define_namespace namespace: :object

On the other hand, it accepts the following:

ActiveOrient::Init.define_namespace :yml=>{:namespace=>:object}

This fixed most of the errors, but not all of them. I have a few classes in my database that use reserved words as names (e.g. File or Gem). Active Orient gives me an error while preallocating those classes, even if I use a prefix for the names.

For instance, the following code:

#!/usr/bin/env ruby

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

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}
ActiveOrient.database = :gems
ActiveOrient::Model.keep_models_without_file = true

ODB = Module.new
ActiveOrient::Init.define_namespace { ODB }
ORD = ActiveOrient::OrientDB.new preallocate: true

returns the following errors:

Hi,

you are right, there was a Bug in Init.define_namspace.
I just updated it here.

Just call the method without a parameter, then no namespace is assigned.

The problem is ActiveOrient::Model.model_dir

I used your script and added
2.4.0 :020 > ActiveOrient::Model.model_dir = '.'
=> "."

the directory exists, but ActiveOrient cannot find an appropriate file.

2.4.0 :021 > ORD = ActiveOrient::OrientDB.new preallocate: true

After that, you might call

puts ORD.class_hierarchy.to_yaml
and
puts ActiveOrient::show_classes

then your console acts almost as the customized one in the bin dir.

The first issue (failing to initialize with no namespace) was due to the bug you found, and now it is solved.

The second issue (failing to create corresponding Ruby classes for the database classes with reserved names) does not get solved by adding "." as model_dir. Again, this only occurs if you have classes in the database with names like "File" or "Gem", which are reserved to classes in the core library of Ruby and are loaded before the script starts running. As a consequence, ActiveOrient fails to initialize Ruby classes with those names if there is no namespace assigned, which is an expected behaviour. But then it also fails to initialize Ruby classes with those names, even when a prefix namespace is used to avoid conflicting class names. That's the part that I find strange.

You are right.

Feature is caused in lib/ClassUtils#allocate_classes_in_ruby

fixed it by checking against a list of reserved words prior to the autoloading process.
If you synchronize your git, you should be able to load the database.
The conflicting classes are omitted.

Improved the Behavior.
If a class is detected, which has a Ruby-Class - or -Method-Conflict,. it is now pushed into the Namespace ActiveOrient::Model
