Hi Folks... Longtime Radiant user, just getting started with Mental
Extensions.
I am creating an extension for posting and managing Comments. I've
created the Comment model, my controllers, and views in the new
Extension, but I'm having trouble extending Radiant's built-in Page
model to include the proper has_many association.
In a nutshell: I want to include a has_many association in the Page
model.
It seems like I should be able to just open the Page class and
include my association like this:
class Page < ActiveRecord::Base
has_many :comments
end
in ../extensions/comments/app/models/page.rb
This doesn't work, of course. It doesn't return an error - as far as
I can tell it just doesn't do anything. Referencing @page.comments in
my views throws an error: "undefined method `comments'". I presume
it's because it is ignoring this class.
I've also tried several module mix-ins that haven't worked (i.e.
packaging a PageExtender module and then including it in Page). For
example:
module PageExtender
def self.included(base)
base.extend(ClassMethods)
end
module ClassMethods
has_many :comments
end
end
in ../extensions/comments/lib/page_extender.rb
And then
def activate
...
Page.send :include, PageExtender
end
in ../extensions/comments/comments_extension.rb
But this terminates with
~/Sites/radiant.mental/vendor/extensions/comments/lib/
page_extender.rb:8: undefined method `has_many' for
PageExtender::ClassMethods:Module (NoMethodError)
Any ideas?
Thanks,
Ryan Heneise
