Share factoriers across modules

[fsauter]

Hi I have a suggestion, maybe you want to add it.

I had the case that I wanted to reuse factories of the core in other modules (and module factories in other modules) using rspec and factory_girl.

I solved it like this:

1 . In you module.gemspec file add the spec/factories folder:

s.files = Dir["{app,config,db,lib}/**/*", "spec/factories/**/*", "MIT-LICENSE", "Rakefile", "README.rdoc"]

2 . In your lib/namespace/module_name/engine.rb add the following initializer

initializer 'model_core.factories', after: 'factory_girl.set_factory_paths' do
    FactoryGirl.definition_file_paths << File.expand_path('../../../../spec/factories', __FILE__) if defined?(FactoryGirl)
end
