Drop down select ruby rails

Here's my code for a form that contains a drop down list -

<div class="field">
<%= f.label :type, "Select profile type"%>
<%=
f.select :type, Profile::TYPES,
:prompt => "Select a profile type"
%>
</div>

Th开发者_高级运维e drop down menu looks fine. But, how would I check which option is selected? I want to route to a different view based on this selection.

Thanks in advance!

The logic of routing to a different view should occur in your controller. When the user submits this form, check the value of the params, and perform your logic to route to a view:

class ExampleController

  def routing
    case params[:example][:type]
    when 'foo'
      redirect_to foo_path
    when 'bar'
      redirect_to bar_path
  end
end

You can create a custom action name, since this routing isn't one of the CRUD operations. You will need to place this route into the config/routes.rb file if it is a custom name.

Optionally, you can bind to the select's onChange event, as mentioned by others to auto-submit the form when the user changes the value. This would still send the data to the controller and perform a redirect. The advantage to this approach is that you can keep your route information out of Javascript, and in the Rail's controller.

You should be able to use jQuery or any other popular Javascript framework to achieve this -- either attach an onChange listener or set the value somewhere and check it. Events, yay, etc.
