title: Rails button_to and using patch vs post
body: <p>I'm having a really hard time getting rails to use the 'button_to' tag with a patch request vs post. </p>
  
  <p>This is my tag:</p>
  
  <pre><code>&lt;%= button_to 'Start Game', { :controller =&gt; 'provides', :id =&gt; @prov_id}, :method =&gt; :patch %&gt;
  </code></pre>
  
  <p>I'm using 'resources :provides' in my routes, and I have an update method in my Provide controller. </p>
  
  <p>Here is the output for provides when I run rake routes..</p>
  
  <pre><code>    provides GET    /provides(.:format)            provides#index
               POST   /provides(.:format)            provides#create
   new_provide GET    /provides/new(.:format)        provides#new
  edit_provide GET    /provides/:id/edit(.:format)   provides#edit
       provide GET    /provides/:id(.:format)        provides#show
               PATCH  /provides/:id(.:format)        provides#update
               PUT    /provides/:id(.:format)        provides#update
               DELETE /provides/:id(.:format)        provides#destroy
  </code></pre>
  
  <p>Everything <em>should</em> be working, but I get the below error...</p>
  
  <pre><code>Started PATCH "/provides?id=1" for 127.0.0.1 at 2014-03-12 19:20:28 -0500
  
  ActionController::RoutingError (No route matches [PATCH] "/provides"):
  </code></pre>
  
  <p>What is going wrong here? This is driving me insane, any help is highly appreciated.</p>
