rails devise edit_user_registration

Question

I am using devise for authentication in my rails app. I am able to sign in and out and also sign up. However once the user is signed in, I want to provide a means for the user to modify his sign in password. For that the app provides a link to the 'edit_user_registration_path' which is shown in the rake routes output below.

When the user clicks on the modify password link below,

<li><%= link_to "Change Password", edit_user_registration_path %></li>

I get the following error

ActionController::RoutingError (No route matches {:action=>"edit", :controller=>"users"}):

I have a UsersController with show, edit and update actions. The edit action is to update the other columns of the Users model.

The routes are set up as below

devise_for :users
resources  :users, only: [:show, :edit, :update]

rake route output -

    new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
        user_session POST   /users/sign_in(.:format)       devise/sessions#create

       user_password POST   /users/password(.:format)      devise/passwords#create

                     PUT    /users(.:format)               devise/registrations#update
                     DELETE /users(.:format)               devise/registrations#destroy
           edit_user GET    /users/:id/edit(.:format)      users#edit
                user GET    /users/:id(.:format)           users#show
                     PUT    /users/:id(.:format)           users#update
                root        /                              home#index

The console log is below

Answer 1

The important lines in the logs above are:

ActionController::RoutingError (No route matches {:action=>"edit", :controller=>"users"}): app/views/layouts/_header.html.erb:22:in `_app_views_layouts__header_html_erb__267315279__621159918'

Routes need to match with all it's params, in this case

edit_user GET    /users/:id/edit(.:format)      users#edit

is not matched when no :id is supplied.

Instead of:

<%= link_to "Settings", edit_user_path %>

Send the current_user as a parameter:

<%= link_to "Settings", edit_user_path(current_user) %>
