Destroy Session, Rails Devise - ruby-on-rails

I've set up Devise to authenticate/register users.
But having problems signing them out.
Have this link:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
It looks like this in HTML:
Sign Out
When I click it - get this error:
No route matches [GET] "/users/sign_out"

First, make sure you have <%= javascript_include_tag :defaults %> in your layout file "application.html.erb."
Then, in your config -> initializers -> "devise.rb" file make sure it says:
config.sign_out_via = :delete
and your "sign_out" code destroy_user_session_path, :method => :delete should work.
If it still doesn't work please comment!
Good luck.

Devise: 'Couldn't find User with 'id'=sign_out' [duplicate]

I've installed devise on my app and applied the following in my application.html.erb file:
<div id="user_nav">
<% if user_signed_in? %>
Signed in as <%= current_user.email %>. This cannot be cheese?
<%= link_to 'Sign out', destroy_user_session_path %>
<% else %>
<%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %>
<% end %>
</div>
I ran rake routes and confirmed that all the routes are valid.
Also, in my routes.rb file I have devise_for :users and root :to => "home#index".
I get the following routing error when clicking the "Sign out" link:
No route matches "/users/sign_out"
Any ideas what's causing the error?
I think the route for signing out is a DELETE method. This means that your sign out link needs to look like this:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
Yours doesn't include the :method => :delete part. Also, please note that for this to work you must also include <%= javascript_include_tag :defaults %> in your layout file (application.html.erb).
I changed this line in devise.rb:
config.sign_out_via = :delete
to
config.sign_out_via = :get
and it started working for me.
You probably didn't include jquery_ujs javascript file. Make sure you are using the latest version of jquery-ujs : https://github.com/rails/jquery-ujs and the last files available :
rails generate jquery:install
You should not have any more rails.js file. If you do, you're probably out-of-date.
Make sure also this file is loaded with defaults, in config/application.rb
config.action_view.javascript_expansions[:defaults] = %w(jquery.min jquery_ujs)
(Again, you should not have rails.js file here).
Finally, add the link as documented on Devise wiki (haml-style):
= link_to('Logout', destroy_user_session_path, :method => 'delete')
And everything will be fine.
The ability to make the Logout link a DELETE RESTful call requires an html attribute data-method = "delete" by using the rails code = link_to('Logout', destroy_user_session_path, :method => :delete).
However, if you do not have the gem jquery-ujs installed or are not calling the resulting javascript in your application.html via = javascript_include_tag "application", the response will be sent as a GET request, and the route will fail.
You have a few options if you do not want to use jquery-ujs or cannot find a way to make it work:
Change config.sign_out_via to equal :get within devise.rb (not recommended, since DELETE is the appropriate RESTful query)
OR Change the link_to to = button_to('Logout', destroy_user_session_path, :method => :delete). With button_to Rails will do the heavy lifting on making the proper DELETE call. You can then style the button to look like a link if you wish.
Try adding a new route to devise/sessions#destroy and linking to that. Eg:
routes.rb
devise_for :users do
get 'logout' => 'devise/sessions#destroy'
end
view:
<%= link_to "Logout", logout_path %>
Use it in your routes.rb file:
devise_for :users do
get '/users/sign_out' => 'devise/sessions#destroy'
end
I had the same problem with rails 3.1.0, and I solved adding in file the followings lines:
app/assets/javascripts/application.js
//= require_tree
//= require jquery
//= require jquery_ujs
With one exception, Jessie's answer worked for me:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
change:
:delete
... to:
'delete'
So the code that worked for me is:
<%= link_to "Sign out", destroy_user_session_path, :method => 'delete' %>
Many answers to the question already. For me the problem was two fold:
when I expand my routes:
devise_for :users do
get '/users/sign_out' => 'devise/sessions#destroy'
end
I was getting warning that this is depreciated so I have replaced it with:
devise_scope :users do
get '/users/sign_out' => 'devise/sessions#destroy'
end
I thought I will remove my jQuery. Bad choice. Devise is using jQuery to "fake" DELETE request and send it as GET. Therefore you need to:
//= require jquery
//= require jquery_ujs
and of course same link as many mentioned before:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
Add:
<%= csrf_meta_tag %> and
<%= javascript_include_tag :defaults %> to layouts
Use these link_to tags
link_to 'Sign out', destroy_user_session_path, :method => :delete
or
link_to 'Sign out', '/users/sign_out', :method => :delete
In routes add:
devise_for :users do
get '/users/sign_out' => 'devise/sessions#destroy'
end
Other option is to configure the logout to be a GET instead a DELETE, you can do that adding the following line on /config/initializers/devise.rb
config.sign_out_via = :get
But as Steve Klabnik wrote on his blog (http://blog.steveklabnik.com/2011/12/11/devise-actioncontroller-routingerror-no-route-matches-get-slash-users-slash-sign-out.html) try to use DELETE because of the semantic of this method.
If you are using Rails 3.1 make sure your application.html.erb sign out looks like:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
And that your javascript include line looks like the following
<%= javascript_include_tag 'application' %>
My guess is that some gems overwrite the new structure of the default.js location.
Check it out with source code in github:
https://github.com/plataformatec/devise/commit/adb127bb3e3b334cba903db2c21710e8c41c2b40#lib/generators/templates/devise.rb (date : June 27, 2011 )
# The default HTTP method used to sign out a resource. Default is :get.
188
# config.sign_out_via = :get
187
# The default HTTP method used to sign out a resource. Default is :delete.
188
config.sign_out_via = :delete
Well, guys for me it was only remove the :method => :delete
<%= link_to('Sign out', destroy_user_session_path) %>
This means you haven't generated the jquery files after you have installed the jquery-rails gem. So first you need to generate it.
rails generate devise:install
First Option:
This means either you have to change the following line on /config/initializers/devise.rb
config.sign_out_via = :delete to config.sign_out_via = :get
Second Option:
You only change this line <%= link_to "Sign out", destroy_user_session_path %> to <%= link_to "Sign out", destroy_user_session_path, :method => :delete %> on the view file.
Usually :method => :delete is not written by default.
I want to add to this even though it's a bit old.
the "sign_out" link didn't work, despite having :method => :delete.
The comment indicating that <%= javascript_include_tag :defaults %> must be included reminded me I had recently added JQuery java script and used simple <script src=""/> tags to include them.
When I moved them from after the :defaults to before, the sign_out started working again.
Hopefully this helps someone.
Most answers are partial. I have hit this issue many times. Two things need to be addressed:
<%= link_to(t('logout'), destroy_user_session_path, :method => :delete) %>
the delete method needs to be specified
Then devise uses jquery, so you need to load those
<%= javascript_include_tag "myDirectiveJSfile" %>
and ensure that BOTH jquery and jquery-ujs are specified in your myDirectiveJSfile.js
//= require jquery
//= require jquery_ujs
Don't forget to include the following line in your application.js (Rails 3)
//= require_self
//= require jquery
//= require jquery_ujs
Include jquery_ujs into my rails application and it works now.
devise_for :users
devise_scope :user do
get '/users/sign_out' => 'devise/sessions#destroy'
end
The problem begin with rails 3.1... in /app/assets/javascript/ just look for application.js.
If the file doesn't exist create a file with that name I don't know why my file disappear or never was created on "rails new app"....
That file is the instance for jquery....
Lots of solutions are there. but mostly use this,
<%= link_to 'Sign out', destroy_user_session_path, method: :delete %>
or config devise.rb with proper sign_out method
In devise.rb
config.sign_out_via = :delete ( or :get which u like to use.)
If you're using HTTPS with devise, it'll break if your sign-out link is to the non-secure version. On the back end, it redirects to the secure version. That redirect is a GET, which causes the issue.
Make sure your link uses HTTPS. You can force it with protocol: "https" in your url helper (make sure you use the url helper and not the path helper).
<%= link_to "Sign out", destroy_user_session_url(protocol: "https"), method: :delete %>
use :get and :delete method for your path:
devise_scope :user do
match '/users/sign_out' => 'devise/sessions#destroy', :as => :destroy_user_session, via: [:get, :delete]
end
In your routes.rb :
devise_for :users do
get '/sign_out' => 'devise/sessions#destroy'
get '/log_in' => 'devise/sessions#new'
get '/log_out' => 'devise/sessions#destroy'
get '/sign_up' => 'devise/registrations#new'
get '/edit_profile' => 'devise/registrations#edit'
end
and in your application.html.erb:
<%if user_signed_in?%>
<li><%= link_to "Sign_out", sign_out_path %></li>
<% end %>
This is what I did (with Rails 3.0 and Devise 1.4.2):
Make sure your page loads rails.js
Use this param: 'data-method' => 'delete'
Good idea to add this param: :rel => 'nofollow'
I am using rails 7. So This was how I had to do it. The important bit is data: { turbo_method: :delete }
<%= link_to t('nav.logout'), destroy_user_session_path, class: "nav-link", data: { turbo_method: :delete } %>
Below were the defaults created by rails when I generated the project.
application.html.erb
<%= javascript_include_tag "application", "data-turbo-track": "reload", defer: true %>
application.js
import "#hotwired/turbo-rails"
import "./controllers"
import * as bootstrap from "bootstrap"
See if your routes.rb has a "resource :users" before a "devise_for :users" then try swapping them:
Works
devise_for :users
resources :users
Fails
resources :users
devise_for :users
the ':method => :delete' in page is 'data-method="delete"'
so your page must have jquery_ujs.js, it will submit link with method delete not method get
I know this is an old question based on Rails 3 but I just ran into and solved it on Rails 4.0.4. So thought I'd pitch in how I fixed it for anyone encountering this problem with this version. Your mileage may vary but here's what worked for me.
First make sure you have the gems installed and run bundle install.
gem 'jquery-rails'
gem 'turbolinks'
gem 'jquery-turbolinks'
In application.js check that everything is required like below.
Beware if this gotcha: it's //= require jquery.turbolinks and not //= require jquery-turbolinks
//= require jquery
//= require jquery_ujs
//= require jquery.turbolinks
//= require turbolinks
//= require_tree .
Next, add the appropriate links in the header of application.html.erb.
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= javascript_include_tag :defaults %>
There seems to be many variations on how to implement the delete method which I assume depends on the version of Rails you are using.
This is the delete syntax I used.
<p><%= link_to "Sign Out", destroy_user_session_path, :method => 'delete' %></p>
Hope that helps dig someone out of this very frustrating hole!
In general when you get "No route matches" but you think you have that route defined then double check the http verb / request method (whether its get, put, post, delete etc.) for that route.
If you run rake routes then you will see the expected method and you can compare this with the request log.

adding a method and html options to link_to in rails?

I'm brand new to ruby and rails and I'm having trouble creating a sign-out link (using devise for auth). I want to pass a custom :method parameter into the link_to function, and set a custom class. I seem to be able to do one or the other but not both.
When I try:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete, { :class => 'signout'} %>
I get the proper result from clicking the link, but I lose my styling. On the other hand, when I try:
<%= link_to "Sign out", destroy_user_session_path, { :class => 'signout'}, :method => :delete %>
I get the styling I want but the link request is passed as GET rather than DELETE, resulting in a routing error.
What am I missing?
Try placing both :class and :method inside the hash.
So:
<%= link_to "Sign out", destroy_user_session_path, { :class => 'signout', :method => :delete} %>
You don't need hash here, because it is already hash :D
link_to "Sign out", destroy_user_session_path, method: "delete", class: "signout"
profit!

Devise/Rails: No route matches [GET] "/users/sign_out"

I'm a bit confused about how devise is routing my requests, for some reason I can't go to the sign-out path in my app now:
ActionController::RoutingError (No route matches [GET] "/users/sign_out")
Here is what my routes related to my User model and Devise look like:
devise_for :users, :controllers => {:registrations => "registrations"}
devise_scope :user do
get '/settings' => 'registrations#edit'
end
Would defining that scope prevent my other routes from working as well?
Update
I don't think that it's supposed to be GET request, as my link looks like:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
If you try to go to /users/sign_out by typing it in the address bar of your browser, or linking to it normally, you will get this error. To summarize some comments and answers here and from issues at the devise repo on github:
This is the intended functionality, RESTful apps should not modify state with a GET request.
You can fix this by making a link that uses the DELETE method as mentioned by #Trip, #fuzzyalej, and the update by #Joseph Silvashy.
Alternatively, (and less recommended), in /config/initializers/devise.rb, you could make the following change
config.sign_out_via = :delete
to
config.sign_out_via = :get
I came across this issue while following along with http://railscasts.com/episodes/209-introducing-devise and with the older version of devise he's using there, this was not an issue.
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"
Just so this post has an answer :
This must be sent with the method, delete so that it does not default to a get
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
devise_for :users
devise_scope :user do
get '/users/sign_out' => 'devise/sessions#destroy'
end
in your routes.rb.
If you're using SSL with Devise controllers, and trying to sign out from an 'http' url, what's happening is it's sending the DELETE request to the #destroy method, but then redirecting to the https version via GET. You can fix this by adding the https to the sign out link like so:
= link_to "Sign out", destroy_user_session_url(protocol: 'https'), method: :delete
Note: must be 'url' instead of 'path'
in Rails 7 the destroy_user_session_path changes a bit on the method.
instead of using the traditional method: :delete that came with the jquery and rails_ujs. Now you need to change that to ..., data: {turbo_method: :delete} and you don't need to setup any additional rails_ujs or jquery
From the rails documentation:
link_to("Destroy", "http://www.example.com", :method => :delete, :confirm => "Are you sure?")
# => Destroy
I had the same problem and to solve it took these steps:
1) include the //= require jquery_ujs in the assets/javascripts/application.js
2) add gem 'jquery-rails' to my gemfile
3) bundle install
... and it worked.

rails delete user session path

I am using the devise gem to make authentication work in my app.
Here's the code I have for signing out:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
I have tried this as well:
<%= link_to "Sign out", destroy_user_session_path%>
Both of which when I click on sign out I get :
No route matches [GET] "/users/destroy"
However when I run rake routes, you can see it (just not GET):
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
How to fix this?
Mitch's answer was close but did not work for me, instead the following syntax did:
<%= link_to "Log out", destroy_user_session_path, :method => :delete %>
Could this help you in the right direction?
https://github.com/plataformatec/devise/issues/1195
Roger's link above is v useful.
I used the following syntax, which worked:
<%= link_to "Log out", destroy_session_path(:user), :method => :delete %>

No route matches "/users/sign_out" devise rails 3

I've installed devise on my app and applied the following in my application.html.erb file:
<div id="user_nav">
<% if user_signed_in? %>
Signed in as <%= current_user.email %>. This cannot be cheese?
<%= link_to 'Sign out', destroy_user_session_path %>
<% else %>
<%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %>
<% end %>
</div>
I ran rake routes and confirmed that all the routes are valid.
Also, in my routes.rb file I have devise_for :users and root :to => "home#index".
I get the following routing error when clicking the "Sign out" link:
No route matches "/users/sign_out"
Any ideas what's causing the error?
I think the route for signing out is a DELETE method. This means that your sign out link needs to look like this:
<%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
Yours doesn't include the :method => :delete part. Also, please note that for this to work you must also include <%= javascript_include_tag :defaults %> in your layout file (application.html.erb).

You probably didn't include jquery_ujs javascript file. Make sure you are using the latest version of jquery-ujs : https://github.com/rails/jquery-ujs and the last files available :

I am using rails 7. So This was how I had to do it. The important bit is data: { turbo_method: :delete }

Below were the defaults created by rails when I generated the project.

<%= javascript_include_tag "application", "data-turbo-track": "reload", defer: true %>
application.js
import "#hotwired/turbo-rails"
import "./controllers"
import * as bootstrap from "bootstrap"
See if your routes.rb has a "resource :users" before a "devise_for :users" then try swapping them:
Works
devise_for :users
resources :users
Fails
resources :users
devise_for :users
the ':method => :delete' in page is 'data-method="delete"'
so your page must have jquery_ujs.js, it will submit link with method delete not method get
I know this is an old question based on Rails 3 but I just ran into and solved it on Rails 4.0.4. So thought I'd pitch in how I fixed it for anyone encountering this problem with this version. Your mileage may vary but here's what worked for me.
First make sure you have the gems installed and run bundle install.
gem 'jquery-rails'
gem 'turbolinks'
gem 'jquery-turbolinks'
In application.js check that everything is required like below.
Beware if this gotcha: it's //= require jquery.turbolinks and not //= require jquery-turbolinks
//= require jquery
//= require jquery_ujs
//= require jquery.turbolinks
//= require turbolinks
//= require_tree .
Next, add the appropriate links in the header of application.html.erb.
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= javascript_include_tag :defaults %>
There seems to be many variations on how to implement the delete method which I assume depends on the version of Rails you are using.
This is the delete syntax I used.
<p><%= link_to "Sign Out", destroy_user_session_path, :method => 'delete' %></p>
Hope that helps dig someone out of this very frustrating hole!
In general when you get "No route matches" but you think you have that route defined then double check the http verb / request method (whether its get, put, post, delete etc.) for that route.
If you run rake routes then you will see the expected method and you can compare this with the request log.
