Question

I have created an application where I am allowing users to log their Workouts.

The user has the ability to keep a private or public log of their workouts and is denoted by a check_box field that passes the integer 1 to the workout.share column. The private log is viewable through the workouts_controller where I am limiting all output by filtering for current_user.

workouts_controller.rb

@workouts = current_user.Workouts.all

The public workouts are shown through a separate community_controller and there I call the workouts like this

community_controller

@workouts = Workouts.all

and then filtering the results in the view with the following

<% @workouts.each do |workout| %>
 <% if workout.share == 1 %> 
  ...
 <% end %>
<% end %>

Best I can tell this is not the preferred way to do this and my suspicion is that I want a named_scope such that I can create a new variable `@shared_workouts’. That said I am not familiar with named scopes so could use some help on where to put what and the correct syntax.

Answer 1

If you are using rails 2, use the following:

class Workout < ActiveRecord::Base
  named_scope :shared, :conditions => {:share => 1}
end

If you are using rails 3, use this instead:

class Workout < ActiveRecord::Base
  scope :shared, where(:share => 1)
end

Then in the community controller, you could simply use @workouts = Workouts.shared.all
