Rails 3 Routes issue on form Edit - ruby-on-rails-3

Question

Basically whats happening is I can create a new item that gets saved to my table in my db. but when I go to edit the item, the form opens up, I make the change and then when I go to submit, it takes me to the same url as the edit page and gives me Routing Error No route matches "/support/14/edit" although if you enter that in the address bar it opens the edit form just fine, but doesn't have any of my changes saved. So here is my code.
routes.rb
resources :support
support_controller.rb
def new
#support_item = Support.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => #support_item }
end
end
# GET /support/1/edit
def edit
#support_item = Support.find(params[:id])
end
# POST /support
# POST /support.xml
def create
#support_item = Support.new(params[:support_item])
respond_to do |format|
if #support_item.save
format.html { redirect_to("/support", :notice => 'Question was successfully created.') }
else
format.html { render :action => "new" }
end
end
end
# PUT /support/1
# PUT /support/1.xml
def update
#support_item = Support.find(params[:id])
respond_to do |format|
if #support_item.update_attributes(params[:support_item])
format.html { redirect_to("/", :notice => 'Question was successfully updated.') }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #support_item.errors, :status => :unprocessable_entity }
end
end
end
support.rb
class Support < ActiveRecord::Base
belongs_to :role
scope :admin_available, order("role_id ASC") do
Support.all
end
def self.available(user)
questions = where(:role_id => 1)
questions += where(:role_id => user.roles)
questions
end
end
_form.html.erb
<% if #support_item.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#support_item.errors.count, "error") %> prohibited this question from being saved:</h2>
<ul>
<% #support_item.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label "Support item for:" %><br />
<%= f.collection_select :role_id, Role.find_by_max(5), :id, :name, {:default => 'everyone'} %>
</div>
<div class="field">
<%= f.label :question %><br />
<%= f.text_field :question, :class => 'genForm_question'%>
</div>
<div class="field">
<%= f.label :answer %><br />
<%= f.text_area :answer, :class => 'genForm_textarea' %>
</div>
<div class="field">
<%= f.label :url %><br />
<%= f.text_field :url, :class => 'genForm_question' %>
</div>
<div class="actions">
<%= f.submit %>
</div>
new.html.erb
<h1>New Support Item</h1>
<% form_for #support_item, :url => { :action => "create" }, :html => { :method => :post } do |f| %>
<%= render 'form', :f => f %>
<% end %>
edit.html.erb
<h1>Editing Support Item</h1>
<% form_for #support_item, :url => { :action => "edit" }, :html => { :method => :post } do |f| %>
<%= render 'form', :f => f %>
<% end %>
I believe thats all the relavent code.

<h1>Editing Support Item</h1>
<% form_for #support_item do |f| %>
<%= render 'form', :f => f %>
<% end %>
You are overriding the URL. It should be able to be auto-generated like that if you are doing everything with standard rest. If that doesn't work out, just know you don't want to submit to /support_items/1/edit, you want to submit to /support_items/1.
