can't get the parent in a polymorphic_belongs_to

[indrekj]

I can't access the parent object when I use a polymorphic relation between my controllers.

Following the documentation, I have a controller like this:

class PhotosController < InheritedResources::Base
  belongs_to :user, :task, :polymorphic => true

  def index
    logger.debug(parent.inspect)
  end
end

But parent always returns nil. It doesn't work either with:

polymorphic_belongs_to :user, :task 

However, it works if I don't use a polymorphic relation:

belongs_to :user 

or

belongs_to :task 

Note that my routes and everything else regarding inherited_resources work fine.

I don't know if it is a bug, or if I misinterpreted the documentation.

thanks for your help

same problem here

[jujudellago]

I have created a demo application to demonstrate the problem...

I think I found the problem.

# Here you can use parent in the views
def show
  show!
end

def show
  resource
  # now you can use parent too
end

def show
  parent # doesn't work, because it is not loaded. @parent_type is nil. It gets loaded after `resource` and after `show!`
end

I added a patch, but its code isn't very nice. Maybe you can get something out of it :).

I tried to apply the patch and now it works as expected !
Thank you so so so much !!!

(I closed the pull request by mistake, I don't think I should be the one doing that ? anyway the pathe solves my problem...)

Could someone please rebase this patch? It would be a nice addition.
