How to devise destroy session and sign out from controller?

Question

Devise destroy session and sign out from controller?

if something_is_not_kosher
  # 1. log this event, 2. send notice
  redirect_to destroy_user_session_path and         


        

Answer 1

destroy_user_session_path(@user) is sign out path for user, but it must requst with DELETE method. redirect_to method will tell broswer to request another path, but broswer just can request with GET method.
So if you want to let user to sign out, you must set a sign out form with DELETE method or with AJAX request to let user sign out but not with redirect_to function.

If you just want to destroy user session, use sign_out @user is ok.

Answer 2

So I ended up solving this by creating a custom signout route

  devise_scope :user do
    get '/signout', to: 'devise/sessions#destroy', as: :signout
  end

and in my controller I have:

if something_is_not_kosher
  redirect_to signout_path and return
end

Answer 3

Why don't you just use devise's built-in sign_out_and_redirect(current_user) method?

Answer 4

Just in case someone can't use it directly.

        <% if user_signed_in? %>
        <li><%= link_to "Logout", destroy_user_session_path, :method => :delete %></li>
        <% else %>
        <li><%= link_to "Sign up now!",  new_user_registration_path%></li>
        <% end %>
