如何在不使用link_to的情况下链接到Ruby-on-rails模板中的Delete Verb

Question

My question is how to tell rails that it should be DELETE request and not GET. It is easy with link_to helper , but how to do this in this situation, as I need this link in given format.

Any suggestions ?

      <a class="item" role="button" tabindex="0" aria-label="Like" href="<%=  logout_path %>">
        <i class="fi-power"></i>
        <label id='itemlabel2'>Logout</label>
      </a>

Answer 1

So naturally, whenever one wants to send a delete request via the link in Rails, it normally would be done like this...

<%= link_to "Delete", @object_name, method: :delete %>

If we then have a look at what happens inside the browser, we will see the following...

<a rel="nofollow" data-method="delete" href="/object_name/1">Delete</a>

As you can see the key ingredient here is data-method="delete" , which initiates a POST request. Hence, my suggestion would be to convert your code to this...

<a class="item" role="button" tabindex="0" data-method="delete" aria-label="Like" href="/logout">
  <i class="fi-power"></i>
  <label id='itemlabel2'>Logout</label>
</a>

Hopefully this might help you out.

UPDATE:

Note that I have used href="/logout" above. I forgot to mention that this implies that inside of your routes.rb file you have to have a correct named route specified to that action, which in this case would be...

delete 'logout' => 'sessions#destroy'

...which in turn would trigger the destroy action inside of the SessionsController.
