<a> link method: :delete HTML

I am relatively new to programing and just wondering if there is a way to have something like = link_to "sign out", destroy_user_session_path, method: :delete, but using an <a> link.

EDIT

Let me clarify, I did use = link_to "sign out", destroy_user_session_path, method: :delete in my code (i'm using haml), but it's still doing a get request. This is in the dropdown menu and it works normally if placed on the actual page. Is there any reason for this, or is rails just being stupid?

<%= link_to('sign out', destroy_user_session_path, method: :delete) %>

if you have generated devise controller, please do it like :

rails d devise:controllers users

instead of:

rails d devise:controllers user

link_to will create an <a> element. It's just a Rails helper method which creates <a> elements, but with the added benefits of being able to use things like the Rails route helpers easily, and attaching extra behaviors (such as non-GET verbs). Normally, clicking an <a> element will cause the browser to execute a GET request, but a delete is not idempotent, so it shouldn't ever be done with a GET request.

Rails' link_to helper helps you around this by allowing you to specify method: :delete, which wires up additional Javascript click handlers for the element, which will cause it to perform a POST via Javascript rather than just letting the browser make a GET request when the link is clicked. It's still an <a> element and may be styled and presented as such, but when clicked, it'll perform a form post using the DELETE verb, rather than performing a simple GET request.
