Inherited Resources and Mongoid

Question

Has anyone had success having Rails 3, Mongoid and Inherited Resources working? Any tips for making it happen? I would love to use both gems.

Currently I am running into:

undefined method `scoped'

On index actions.

Thanks!

BTW a workaround for the scoped issue is to override collection like so:

class CampaignsController < InheritedResources::Base

  def collection
    @campaigns ||= end_of_association_chain.paginate(:page => params[:page])
  end

end

But I am looking for a more holistic approach

If you are using only mongoid, what you should do is to overwrite the default collection behavior in Inherited Resources. The default behavior is this:

https://github.com/josevalim/inherited_resources/blob/master/lib/inherited_resources/base_helpers.rb#L22-24

That said, the following should do the trick:

module MongoidActions
  def collection
    get_collection_ivar || set_collection_ivar(end_of_association_chain.all)
  end
end

InheritedResources::Base.send :include, MongoidActions

You can even default the collection to paginate and have pagination for free in all pages.
