如何通过一种资源为另一种资源编写named_scope？

我有一个属于锻炼的群组资源。锻炼可以是公开的或私人的，并由锻炼表中的 share 列指定（该列是一个整数，如果锻炼是公开的，则包含 1）。

我正在尝试致电所有与公共锻炼相关的团体。我认为这需要通过 named_scope 完成，但我不确定语法。

在 groups_controller 中，我假设我会调用：

@groups = Group.public_groups.all

How should I write the named_scope in Group.rb? （我在 Rails 2.3.8 中）

named_scope :public_groups, ...

原文

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, ...

这是一种方法：

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

@groups = Group.public.all

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
