Submit button outside form_for loop

问题

I have set up some horizontal tabs using twitter bootstrap and I am rendering a form inside each of the tabs:

<div class="tab-content">
  <div id="tab1" class="tab-pane active">
      <%= render :partial => "shipdr/websites/form", locals: {:@shipdr_website => shipdr_website} %>
  </div>
  <div id="tab2" class="tab-pane">
    Another form (not yet implemented)
  </div>
  <div id="tab3" class="tab-pane">
    Another form (not yet implemented).
  </div>
</div>

Then in shipdr/websites/form I have:

<%= simple_form_for(@shipdr_website) do |f| %>
  <% if @shipdr_website.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@shipdr_website.errors.count, "error") %> prohibited this shipdr_website from being saved:</h2>

      <ul>
      <% @shipdr_website.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.input :name %>
  </div>
  <div class="field">
    <%= f.input :url %>
  </div>
  <div class="field">
    <%= f.input :api_key %>
  </div>
  <div class="actions">
    <%= f.submit nil, :class => "btn btn-primary" %>
  </div>
<% end %>

I want to move the submit button outside of the "tab-content" area so when a user clicks the submit button, all three forms area submitted. All forms will use that same model and the same action but will have different field. The idea is similar to a wizard except I am using tabs.

Does anyone have any idea how I can move the submit button outside of the form_for loop and how I can submit the three forms with a single button?

I don't know if you can submit 3 forms at a time. But you can do this:

<div class="tab-content">
  <%= simple_form_for(@shipdr_website) do |f| %>
    <div id="tab1" class="tab-pane active">
      <%= render :partial => "shipdr/websites/form", locals => {:f => f, :shipdr_website => @shipdr_website} %>
    </div>
    <div id="tab2" class="tab-pane">
      Another form (not yet implemented)
    </div>
    <div id="tab3" class="tab-pane">
      Another form (not yet implemented).
    </div>
  <% end %>
</div>

And remove that from your partials, leaving just the inputs.

<%= simple_form_for(@shipdr_website) do |f| %>

I think the best way of doing that is with Javascript: you can move the button and send 3 forms at a time via Ajax. If you use Jquery you can use http://jquery.malsup.com/form
