No route matches [GET] "/users/sign_out" - authentication

Question

Here is my actual error: No route matches [GET] "/members/sign_out"
Since most people will use "users" I thought it would be more helpful to have that in the title. At any rate, I am essential unable to logout. I can successfully edit my member profile.
I am using devise 1.4.2 and Rails 3.1.0.rc4. Also, I have generated two separate devise models - one called "members" and the other called "admins". I was able to register and log into both of them (simultaneously) by manually navigating to the correct URL path (i.e., localhost:3000/admins/sign_in/). I created some links within my application.html.haml layout file by following this RailsCast on Devise. I am aware that it only addresses signin/signout links for "members."
If I click on the signout link I get the above error. This occurs if I manually navigate to either signout URL (i.e., localhost:3000/admins/sign_out/).
Can someone tell me why this is happening? Below are the various related files. And of course, I'm a newbie...

Answer 1

You can end a session via get by changing the devise configuration in initializers.
# The default HTTP method used to sign out a resource. Default is :delete.
config.sign_out_via = :get
Just open the link and your session is removed.

Answer 2

I had a similar problem, but addition of the :method=> :delete didn't work.
I was able to add a new route for a the get request by commenting out the devise_for :users and adding
devise_for :users do
get '/users/sign_out' => 'devise/sessions#destroy'
end

Answer 3

I had a similar problem.
My view code was like this:
<%= link_to " exit", destroy_user_session_path, method: :delete %>
After adding the following change to routes.rb it worked,
devise_for :users
devise_scope :user do
get '/users/sign_out' => 'devise/sessions#destroy'
end

Answer 4

Although I don't know the cause, the reason why you are getting that message is because in your routes you have
destroy_member_session DELETE /members/sign_out(.:format) {:action=>"destroy", :controller=>"devise/sessions"}
Which means that route is only available with the DELETE method as opposed to GET. This is a bit weird since in the docs for devise it says that it should create it as GET route (https://github.com/plataformatec/devise/blob/master/lib/devise/rails/routes.rb#L30)
With it as a DELETE route, you should be able to logout using
link_to :logout, destroy_member_session_path, :method => :delete

Answer 5

I just needed to add the
//= require jquery
//= require jquery_ujs
to my application.js

Answer 6

If you want to use :delete method for security reasons and not be dependent on jquery-ujs you can use button_to instead of link_to, like:
button_to "Log out", destroy_user_session_path, method: :delete
if using link_to you must be sure to have javascript active:
Note that if the user has JavaScript disabled, the request will fall
back to using GET.
As seen in docs

Answer 7

In devise.rb, change
config.sign_out_via = :delete
to
config.sign_out_via = :get
This worked for me. I went crazy with this because the default is delete and I don’t understand why.
This works, but I am not sure whether it affects other elements in the application.

Answer 8

We still can use :method => :delete in my code, like that
= link_to "Sign out", destroy_user_session_path,:method => :delete
The reason i think we fail to load javascript that include jquery, make sure
= javascript_include_tag "application" (haml- you can use html too)
to include jquery-ui and jquery-ujs. So if it still error, i suggest to change rails gem in GEMFILE to version 3.2.6 and call bundle update to update gems. It works for me!

Answer 9

= link_to "Sign out", destroy_user_session_path,:method => :delete
will NOT work instead use this,
= link_to "Sign out", destroy_user_session_path,:method => 'delete'
should do the trick or worse case add require jquery_ujs in your application.js

Answer 10

In Rails 6:
I just changed the link_to to button_to, and the 'sign out' works properly
<%= button_to "Sign out", destroy_user_session_path, method: :delete %>

Answer 11

In rails 7, you need to add data: { turbo_method: :delete" } to link_to. So the link_to would look like this
<%= link_to "Log out", destroy_user_session_path, data: { turbo_method: :delete } %>

Answer 12

Using Rails4, I had to use the following method:
<%= link_to "Logout", destroy_admin_session_path, method: :delete %>
Emphasis on where the colons are on method: and :delete

Answer 13

Maybe that will help somebody.
Upgraded from Rails 3.0 to 3.1 and found this problem.
This fixed it for me:
routes.rb:
devise_for: users
devise.rb:
config.sign_out_via = :delete
application.html.erb:
<%= javascript_include_tag "application" %>
* not :defaults
_login_items.html.erb:
<%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
app/assets/javascripts/application.js
//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require_tree .
and I had in javascript/ jquery.js, jquery_ujs.js from 3.0 version that I've removed.

Answer 14

You may have removed assets/javascripts/*
Run rails generate jquery:install --ui this will generate all the javascripts as shown below
xxxx#xxxxx:~/Projects/Rails_apps/rtest$ rails generate jquery:install --ui
remove public/javascripts/prototype.js
remove public/javascripts/effects.js
remove public/javascripts/dragdrop.js
remove public/javascripts/controls.js
copying jQuery (1.7.1)
create public/javascripts/jquery.js
create public/javascripts/jquery.min.js
copying jQuery UI (1.8.16)
create public/javascripts/jquery-ui.js
create public/javascripts/jquery-ui.min.js
copying jQuery UJS adapter (822920)
remove public/javascripts/rails.js
create public/javascripts/jquery_ujs.js
Go to your layout e.g application.html.erb and edit <%= javascript_include_tag :all %>
That worked for me :)

Answer 15

FWIW I have also run into this problem. Have looked into all of the suggested answers however the only one which worked was to foto open routes.rb and comment out the following line:
devise_for :users
Below that, add the following line:
devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' end

Answer 16

The problem begins with rails 3.1 in assets/javascript/. Just look for application.js, and if the file doesn't exist, create a file with that name. I don't know why my file disappears or never was created on rails new app... that file is the instance for jquery.

Answer 17

#creamhost say,
devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' end
but it is not correct solution for me (Rails4). I solved our problem (#Olives' answer),
link_to :logout, destroy_member_session_path, method: :delete

Answer 18

I am using rails version 5. I encounter this problem also. The simple fix I did was to changing the devise configuration in initializes to the default.
From :
config.sign_out_via = :get
To :
config.sign_out_via = :delete

Answer 19

Keep your devise.rb using the correct HTTP method:
# good
config.sign_out_via = :delete
# bad
config.sign_out_via = :get
Use button_to instead of link_to
# good
= button_to "Sign Out", destroy_user_session_path, method: :delete
# bad
= link_to "Sign Out", destroy_user_session_path, method: :delete"
If you are using bootstrap (keep it classy)
= link_to "Sign Out", destroy_user_session_path, method: :delete, class: "btn btn-default btn-sm"

Answer 20

Just use the following for your sign out link:
<%= link_to "Sign out", destroy_user_session_path, method: :delete %>

Answer 21

//= require jquery_ujs
You are missing this line in your assets. There's no need to get /users/signout request. Put this line into JavaScript file at very top of the page.

Answer 22

Had the same problem and remembered it only started happening after I decided to "clean up" my Javascript files. So I ran rails generate jquery:install --ui again and this solved it for me. (You can ignore the --ui part if you don't need JQuery UI, I suppose.)

Answer 23

devise_for :users
devise_scope :user do
get '/users/sign_out' => 'devise/sessions#destroy'
end
That works for me

Answer 24

I believe this error is due to devise library template not aligned with changes on rails 7,
In short, you are not sending the request in method delete as expected due to the Javascript library that does that is now missing.
you can change :
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
with
<%= link_to "Sign out", destroy_user_session_path, data: { "turbo-method": :delete }, class: "btn btn-danger ml-3" %>
And it will work again

Answer 25

This worked for me:
<%= link_to 'Sign out', destroy_user_session_path, data: { turbo_method: :delete } %>

Answer 26

It happens only on windows.. Add the following thing to your Application.html.erb file.
devise_for :users
devise_scope :user do
get '/users/sign_out' => 'devise/sessions#destroy'
end
