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
