Rails 3 Routing Error

Question

I had this working yesterday, I don't know what I did to break it.

Here are the routes for a RESTful controller:

brand_responsibilities    GET    /brands/:brand_id/responsibilities(.:format)          {:action=>"index", :controller=>"responsibilities"}
brand_responsibilities    POST   /brands/:brand_id/responsibilities(.:format)          {:action=>"create", :controller=>"responsibilities"}
new_brand_responsibility  GET    /brands/:brand_id/responsibilities/new(.:format)      {:action=>"new", :controller=>"responsibilities"}
edit_brand_responsibility GET    /brands/:brand_id/responsibilities/:id/edit(.:format) {:action=>"edit", :controller=>"responsibilities"}
brand_responsibility      GET    /brands/:brand_id/responsibilities/:id(.:format)      {:action=>"show", :controller=>"responsibilities"}
brand_responsibility      PUT    /brands/:brand_id/responsibilities/:id(.:format)      {:action=>"update", :controller=>"responsibilities"}
brand_responsibility      DELETE /brands/:brand_id/responsibilities/:id(.:format)      {:action=>"destroy", :controller=>"responsibilities"}

My form looks like this:

<%= form_for :responsibility, :remote => true do |f| %>
    <%= f.hidden_field :access_request_id, :value => ar.id %>
    <%= f.hidden_field :user_id, :value => user.id %>
    <%= f.hidden_field :brand_id, :value => @brand.id %>
    <%= f.submit %>
<% end %>

But I get a 404 now with this log message:

Started POST "/brands/30/responsibilities" for 127.0.0.1 at Tue Oct 26 10:47:17 -0400 2010

ActionController::RoutingError (No route matches "/brands/30/responsibilities"):

It sure looks like the route matches to me! What am I missing?

Update: I also tried this in the console:

rs.recognize_path '/brands/30/responsibilities', :method => :post

and the response is:

=> {:controller=>"responsibilities", :brand_id=>"30", :action=>"create"}

What is my deal?

UPDATE #2:

I found the cause, though I don't know why it's the cause. I have another field:

<%= button_to "Deny", brand_responsibilities_path(@brand, :ar => ar), :remote => true, :method => :delete %>

That I was including in the form. I left it out for brevity's sake before because I didn't think it was important. I see that was a bad idea.

Does anybody know why the presence of that line in the form causes the weird routing error?

Answer 1

It appears as if I am an idiot.

Leaving out that crucial piece of information was a bad idea. Having a button_to within a form is a no-no, it creates a form within a form.

Rookie mistake. Too bad I've been doing this for a long time. Upvotes to the commenters, sorry for wasting your valuable time.
