Question

I am trying to override an active resource method like explained in this question : Remove .xml extension from ActiveResource request and this one :
i want to use a REST api, i cannot manage to set active resource to use it

To do so i tested :

Creating in the /config/in itializers/ folder of my app a file named active_resource.rb with the following code :

class ActiveResource::Base   
  def element_path(id, prefix_options = {},query_options = nil)
  check_prefix_options(prefix_options)
  prefix_options, query_options = split_options(prefix_options) if query_options.nil?
  "#{prefix(prefix_options)}#{collection_name}/#{URI.parser.escape id.to_s}#{query_string(query_options)}"   
  end 
end

Adding the method inside my model. Here is my model code :

class Player < ActiveResource::Base
  def element_path(id, prefix_options = {}, query_options = nil)
    check_prefix_options(prefix_options)

    prefix_options, query_options = split_options(prefix_options) if query_options.nil?
    "#{prefix(prefix_options)}#{collection_name}/#{URI.parser.escape id.to_s}#{query_string(query_options)}"
  end
  self.site = "http://ws.maniaplanet.com/"
  self.user="**********"
  self.password="*********"
end

To validate the overriding of my custom code I have tried to use

puts  "called this method"

or

ActionController::Base.logger.info "called this method"

It has never worked.

Why can’t i override the rails method element path ?

UPDATE

Tried to put active_resource.rb in extra after uncommenting the config.autoload_paths += %W(#{config.root}/extras) line in application.rb. No change

If i put the base.rb file with my class and method in lib/active_resource/ it breaks my app. I cannot launch rails server anymore

You should override class method, not instance one, so:

class Player < ActiveResource::Base

  def self.element_path(id, prefix_options = {}, query_options = nil)
    #...
  end

end

That would be enough, if you going to make requests only from Player model.

If you want this behaviour for any model, you should monkey patch ActiveResource::Base, again, the class method.

# config/initializers/active_resource_patch.rb
class ActiveResource::Base

  def self.element_path(id, prefix_options = {}, query_options = nil)
    #...
  end

end
