authenticity_token csrf token rails
On same page of a rails 4 app I have a. in the head"content" attribute value of is taken from requestforgeryprotectiontoken, and, by default, is :authenticitytoken. I erased all cookies and since then I am not able to make POST actions without a CSRF token authenticity exception.Tags: ruby-on-rails ruby ruby-on-rails-4 csrf. That led me to dive into how Rails validates a CSRF token, by way of stepping through the source file.Like, sure, now I know what happens when I insert beforeaction :verify authenticitytoken into a controller, but that didnt fix my problem. A CSRF token works like a secret that only your server knows - Rails generates a random token and stores it in the session. Your forms send the token via a hidden input and Rails verifies that any non GET request includes a token that matches what is stored in the session. The code to read the csrf-token is available in the rails/jquery-ujs, so imho it is easiest to just use that, as followsIm using Rails 4.2.
so when a form is submitted the submission can be checked for the validity of the token. The problem with loading it through the iframe is that it causes Cant verify CSRF token authencity on the Rails side when I send a .post() request.I had fixed the same issue like that of "Cant Verify CSRF Token Authenticity". You can turn CSRF off for certain controller actions.
