Model's method not being recognized when called
- by Brian Roisentul
I'm using ruby on rails 2.3.2 and also using the acts_as_taggable_on puglin. That generated me two db tables: tags and taggings.
As I didn't need anything more from those, I didn't create a Tag model, for example. Now the project is more mature, I need to create some methods for tags, so I created a Tag model with some methods in it.
The model looks something like this:
class Tag < ActiveRecord::Base
def self.get_parent
parent = Tag.find(self.parent_id)
return parent
end
end
When I call it from a controller, it won't find the method. This is the code:
tag = Tag.find(tag_id)
the_parent = tag.get_parent
This will throw an error saying:
undefined method `get_parent' for #<Tag id: 13, name: "Historia", parent_id: 12>
I don't know what's wrong. Any help will be appreciated.
