getting const_defined? error when belongs_to :event is used

[krglobal]

I am upgrading from Rails 2.3 to Rails 3.2 and have many controllers using make_resourceful.

I have a very simple model called TemplateType which I use in my mailings controller.

When I try to get any row from it in my new method, I get:

undefined method `const_defined?' for "event":String

it is failing when trying to run through the controllers parents for some reason... see below.

if I remove the belongs_to :event statement and put in my own code to get the parent event, (my controller is mailings which have an event parent) then the problem clears up. what is make_resourceful trying to do here and how can I get it to not fail? what is different from Rails 2.3 version I wonder.

undefined method `const_defined?' for "event":String

@krglobal Did you solve this issue? This happened to me too after I upgraded from rails 3.x to 4.x

[krglobal]

No i did not really solve it but worked around it. by excluding my index
methods from make resourceful and writing my own code to get parent object,
then the problem went away (looking for parent object constant on finder
methods that had nothing to do w parent object).

If you know how to fix root cause I'd love to hear how.
Thx,
Kurt

now I got another one on an index method that was not even included in the list of make_resourceful methods after making some random code changes that seemingly had nothing to do with it.
eventually I pulled out the belongs_to :member statement and it cleared up.

stay away from belongs_to in your make resourceful usage!

Thanks for the hint. We started to get rid of the whole gem.
