Undefined method when including mongoid embedded docs in inherited_resource collections

Question

I have a couple mongoid models:

class Album
  include Mongoid::Document
  field :name, type: String
  embedded_in :band
end
class Band
  include Mongoid::Document
  field :name, type: String
  embeds_many :albums
end

And I'm trying to get inherited_resources to include the embedded albums in the json for bands, like so:

class BandsController < InheritedResources::Base
  respond_to :html, :xml, :json
  def permitted_params
    params.permit!
  end
protected
  def collection
    @bands ||= end_of_association_chain.includes(:albums)
  end
end

But I get the following error when trying to retrieve the list of bands:

undefined method `eager_load' for Mongoid::Relations::Embedded::Many:Class

Any idea what I might be doing wrong?

Answer 1

I am pretty much sure the error here is because you are overwriting collection method. collection is an internal method that mongoid uses to do operations in the collection, so I guess if you overwrite it would cause some conflicts.
