Question

I have a groups resource that belongs_to Workouts. Workouts can be public or private and are designated as such by the column share in the workout table (which is an integer and contains a 1 if the workout is public).

I am trying call all groups that are associated with public workouts. I assume this needs to be done through a named_scope but I am unsure of the syntax.

In the groups_controller I am assuming I would call:

@groups = Group.public_groups.all

How should I write the named_scope in Group.rb? (I’m in rails 2.3.8)

named_scope :public_groups, ...

Answer 1

Here’s one way to do it:

class Group < ActiveRecord::Base
  belongs_to :workout
  named_scope :public, {:conditions => 'workouts.share = 1', :include => :workout}
end

@groups = Group.public.all
