Rails 3.2 `link_to` (in email) with `method: :put` still producing GET request

Question

In my app I have automated e-mails reminding applications to complete the next step in the interview process. The e-mail has an opt out link which, when clicked, should hit

Answer 1

It's because this is a link in context of an email. It's documented behavior:

method: symbol of HTTP verb - This modifier will dynamically create an HTML form and immediately submit the form for processing using the HTTP verb specified. Useful for having links perform a POST operation in dangerous actions like deleting a record (which search bots can follow while spidering your site). Supported verbs are :post, :delete, :patch, and :put. Note that if the user has JavaScript disabled, the request will fall back to using GET. If href: '#' is used and the user has JavaScript disabled clicking the link will have no effect. If you are relying on the POST behavior, you should check for it in your controller's action by using the request object's methods for post?, delete?, patch?, or put?.

There are security reasons to disallow executable JavaScript in emails, as well as forms. Therefore, it's impossible to render a form with JS and execute a PUT request, so this falls back to GET as stated in citation above.
