title: form for custom action
body: <p>I have a form like this</p>
  
  <pre><code>&lt;%= form_tag organizations_add_user_path, :method =&gt; :put do %&gt;
    &lt;label&gt;&lt;h2&gt;Add user&lt;/h2&gt;&lt;/label&gt;
    &lt;%= text_field_tag :nick %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>I want this form to process the action <code>add_user</code> from <code>Organizations</code> controller</p>
  
  <p>My routes are this</p>
  
  <pre><code>resources :users, :sessions, :documents, :storages, :organizations
  
  match 'dashboard' =&gt; 'dashboard#index'
  match 'profile' =&gt; 'users#profile'
  match 'organizations/add_user' =&gt; 'organizations#add_user', :via =&gt; :post
  </code></pre>
  
  <p>But when I submit my form, the app sends me to <code>update</code> method form organizations, with Organization id as <code>add_user</code>. What am I doing wrong?</p>
