has_many_through_with_join_model¶ ↑

Access the associated join model from any element in your has_many :through association collection

Getting started¶ ↑

./script/plugin install git://github.com/TylerRick/has_many_through_with_join_model.git

class Group
  has_many :users, :through => :memberships, :extend => WithJoinModel
end

group.users.with_join.map(&:membership) # => [<Membership>, <Membership>, ...]
group.users.with_join.map(&:join)       # => [<Membership>, <Membership>, ...]

Name ideas?¶ ↑

Please let me know if you have suggestions for improving naming – the plugin, the module name/namespace (WithJoinModel?), the methods (with_join? join? through?), etc.

For that matter, suggestions of any sort are welcome: github.com/TylerRick/has_many_through_with_join_model/issues

Note on Patches/Pull Requests¶ ↑

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request.

The initial starting point for setting up the specs was attribute_normalizer – thanks for showing me how to write specs for an ActiveRecord plugin.
