Rails - Jan 2008 - REST Design Question

I have 2 models Roles and Rights with many to many Relationship.

Without Rest:
Controller: Action
Roles: list,edit,create,destroy,map_rights
Rights: list,edit,create,destroy,list_by_role

NOTE: map rights function will map/unmap multiple rights to a
particular role using a list of checkboxes.

What would be the design following  Rest ?

Pankaj

With REST:

Roles: index, new, create, edit, update, destroy
Rights: index, new, create, edit, update, destroy



Now, I guess, an explanation.

List and index should be interchangeable; just get rid of
''list'' for
''index''.

I assume there''s a means of creating these rights/roles from the first
place. This form would usually be in a ''new'' action (the form
POSTs to
''create''). And while ''edit'' is good to
provide a GET form for a
record, the form would post (using PUT) to ''update'' to write
the
changes. ''Destroy'' stays.

''map_rights'' seems to be an ''update'' action
if it''s modifying that
role''s rights.

And finally, ''list_by_role'' could be achieved with the
following
established routes:

# config/routes.rb
map.resources :roles, :has_many => :rights
map.resources :rights

Now you have role_rights_path(@role), which will allow you to use the
RightsController#index action to list just the rights of a particular
role, as long as @role is established from params[:role_id]. You could
just detect with a before_filter:

# app/controllers/rights_controller.rb
before_filter :get_rights

protected

def get_rights
  if @role = Role.find params[:role_id]
    @rights = @role.rights
  else
    @rights = Right.find :all
  end
end

Now, the following two URLs will ''list'' rights and
''list_by_role'' with
ID 1
http://0.0.0.0:3000/rights
http://0.0.0.0:3000/roles/1/rights

Now, go convert all those crudful controllers!
