accepts_nested_attributes_for problems with inheritance

#5017

The following model setup is being used: http://gist.github.com/458559
The Admin::Candidate version of the model is an enhanced version which is only loaded when the user is an admin.

It is not possible to set accepts_nested_attributes_for to the child model when the parent has it too.

In activerecord/lib/active_record/nested_attributes.rb:251 a delete_method is performed for a method that is not defined in that class, although method_defined? says it is. I think the old behaviour of simply overwriting the method is good enough. This very same construction worked in rails 2.3 just fine.

    To follow up on this:
    If you only add accepts_nested_attributes to the child model it won't work properly either.
    At the time the check for autosave is performed on the reflection it is nil. Not because it is being reset, but because it reads the reflection settings of its parents.

    I hope I am clear. I am also not sure if this needs to be in this same ticket, otherwise I will create a new one when I have more time.
