Problems with edit action with paperclip in Rails3 - ruby-on-rails-3

Question

So I ran a regular generate scaffold and used a stock form to handle uploads.
All uploads work nicely and the image is attached perfectly. The issue I get is when I go to 'Edit' and try to change the image, this is the error I get:
Routing Error
No route matches "/uploads"
Here is what my controller looks like. The name is 'uploads_controller.rb'
class UploadsController < ApplicationController
# GET /uploads
# GET /uploads.xml
def index
#uploads = Upload.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => #uploads }
end
end
# GET /uploads/1
# GET /uploads/1.xml
def show
#upload = Upload.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => #upload }
end
end
# GET /uploads/new
# GET /uploads/new.xml
def new
#upload = Upload.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => #upload }
end
end
# GET /uploads/1/edit
def edit
#upload = Upload.find(params[:id])
end
# POST /uploads
# POST /uploads.xml
def create
#upload = Upload.new(params[:upload])
respond_to do |format|
if #upload.save
format.html { redirect_to(#upload, :notice => 'Upload was successfully created.') }
format.xml { render :xml => #upload, :status => :created, :location => #upload }
else
format.html { render :action => "new" }
format.xml { render :xml => #upload.errors, :status => :unprocessable_entity }
end
end
end
# PUT /uploads/1
# PUT /uploads/1.xml
def update
#upload = Upload.find(params[:id])
respond_to do |format|
if #upload.update_attributes(params[:upload])
format.html { redirect_to(#upload, :notice => 'Upload was successfully updated.') }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #upload.errors, :status => :unprocessable_entity }
end
end
end
# DELETE /uploads/1
# DELETE /uploads/1.xml
def destroy
#upload = Upload.find(params[:id])
#upload.destroy
respond_to do |format|
format.html { redirect_to(uploads_url) }
format.xml { head :ok }
end
end
end
The 'upload.rb' model file looks like this:
class Upload < ActiveRecord::Base
has_attached_file :image
end
show.html.erb
<p id="notice"><%= notice %></p>
<p>
<b>Name:</b>
<%= #upload.name %>
</p>
<p>
<b>Description:</b>
<%= #upload.description %>
</p>
<p>
<b>Your Image:</b>
<%= image_tag #upload.image.url %>
</p>
<%= link_to 'Edit', edit_upload_path(#upload) %> |
<%= link_to 'Back', uploads_path %>
edit.html.erb
<h1>Editing upload</h1>
<%= render 'form' %>
<%= link_to 'Show', #upload %> |
<%= link_to 'Back', uploads_path %>
_form.html.erb
<%= form_for (#upload), :url => uploads_path, :html => { :multipart => true } do |f| %>
<% if #upload.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#upload.errors.count, "error") %> prohibited this upload from being saved:</h2>
<ul>
<% #upload.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :description %><br />
<%= f.text_field :description %>
</div>
<div class="field">
<%= f.file_field :image %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Thanks.
Edit: Relevant part of the 'rake routes' output:
uploads GET /uploads(.:format) {:action=>"index", :controller=>"uploads"}
uploads POST /uploads(.:format) {:action=>"create", :controller=>"uploads"}
new_upload GET /uploads/new(.:format) {:action=>"new", :controller=>"uploads"}
edit_upload GET /uploads/:id/edit(.:format) {:action=>"edit", :controller=>"uploads"}
upload GET /uploads/:id(.:format) {:action=>"show", :controller=>"uploads"}
upload PUT /uploads/:id(.:format) {:action=>"update", :controller=>"uploads"}
upload DELETE /uploads/:id(.:format) {:action=>"destroy", :controller=>"uploads"}

So it seems the error was in my _form partial.
I had a :url attribute defined, when I shouldn't have.
Paperclip needs to update their install instructions to reflect that change for Rails 3.
The wonderful guys in #RubyOnRails on irc.freenode.net helped me out with this one.
