Menu
I'm tinkering with Rails 6 and I am constantly getting ActionController::InvalidAuthenticityToken on forms generated by rails, such as (implementing the rails tutorial book register/login flow)
<%= form_for(@user, url: 'signup') do |f| %>
<%= render 'partials/error_messages' %>
<%= f.label :name, "Nimi" %>
<%= f.text_field :name %>
<%= f.label :email, "E-mail" %>
<%= f.email_field :email %>
<%= f.label :password, "Parool" %>
<%= f.password_field :password %>
<%= f.label :password_confirmation, "Korda parooli" %>
<%= f.password_field :password_confirmation %>
<%= f.submit "Loo konto", class: "button-green" %>
<% end %>
this happens on all forms, and the output dumps look like this
application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Storebase - kaasaegsed e-poed!</title>
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
</head>
<body class="bg-gray-100 text-gray-900">
<% flash.each do |message_type, message| %>
<div class="bg-blue-100 text-blue-500 flex items-center h-12 px-12 shadow-lg flash-<%= message_type %>"><%= message %></div>
<% end %>
<%= yield %>
<%= debug(params) if Rails.env.development? %>
</body>
</html>
What should I do?

Was seeing this in a controller that subclasses Devise to get after action hooks. It was only happening on :destroy actions for me.
class MySessionsController < Devise::SessionsController
after_action :after_login, only: [:create]
after_action :after_logout, only: [:destroy]
private
def after_login
end
def after_logout
end
I don't see the risk in skipping authenticating on a destroy, so adding this line inside the controller fixed the issue for me: skip_before_action :verify_authenticity_token, only:[:destroy]. ¯_(ツ)_/¯
Is this a bug or feature introduced by the Rails6 upgrade? Is there a security risk that I'm not seeing by skipping? Any insights would be appreciated :)
