Before I answer your question, something looks a little off. destroy_user_session_path would normally be used to Log Off, not for Sign Up. However, to answer your question, there are two independent actions here. The first is the use of the link_to method to generate a html anchor tag. In your case, this would look something like: <a data-method="delete" href="/users/sign_out" rel="nofollow">Sign Up</a> This gets passed to the browser as part of the html for the page. Now, let's assume the user clicks on this link. This is generates a completely separate action from the one above. The browser now processes the anchor link. However, in HTML, anchor links (the <a ... >) only support GET method requests and no matter what you put in there, the request generated will be a GET. Rails has written javascript to intervene, detect the "data-method" and generate a request with the appropriate method (in this case, delete). If javascript is disabled or there's an error, it will get sent as a GET request. Therefore, the following information gets passed to the routing table: URL: /users/sign_out METHOD: Delete It looks for a route matching both of those parameters and routes accordingly. Please note the routing table does not define methods for a request, it uses the method passed in a request in combination with the URL to determine the appropriate route for the request (or reject it if no rule is defined).
