Folks, Trying to get my head around this - and I''ve made it work, but it feels rather hackish. Let''s say I have two resource types: User and Widget. A User has many Widgets, a Widget belongs to a User In routes.rb I have Widgets mapped as a nested resource: map.resources :users do |users| users.resources :widgets end In an ideal world, I''d like to be able to submit many Widgets to users/1/widgets via user_widgets_url, which, for a single resource would look like: <% form_for([@user, @widget], :url => user_widgets_url) do |f| %> <%= f.text_field :some_widget_field %> ... <% end %> That would then post to user/1/widgets (invoking the create method) and all would be well with little controller code. But what if I wanted to submit many distinct widgets in this form submit (effectively creating n number of new Widgets associated to a User)? I realize that RESTful resources are by-and-large created to work with single instances of a resource (outside of index) but what if that ''resource'' is a collection. I''ve seen the nested_resources examples in documentation but in most cases it sets up something like this in user.rb: def widgets_attributes=(attributes) # Process the attributes hash end And then utilizes fields_for in my template to write out the appropriate fields for a widget... Is that really the convention? Seems like I''d want to post to the widgets controller as that''s the ''resource'' in question? So - in summary - what''s the current idiom for posting a collection of resources? Post to the controller associated with the resource (widgets_controller) *or* set up widgets_attributes in user.rb? Too much? Thanks in advance folks! Cory -- Posted via http://www.ruby-forum.com/.
