How To: Allow users to edit their password

By default, Devise allows users to change their password using the registerable module.

Here we are going to provide a few solutions on how to allow users to change their password.

Solution 1.

Just make such link in your view:

<%= link_to "Change your password", edit_user_registration_path %>

Notice: This'll work if you didn't do any modification in your routes.rb file such as

devise_for :users, :skip => [:registrations]

Solution 2.

Lets suppose that you don't want to allow to sign up but you want to allow to change password for registered users. Just paste this code in routes.rb:

devise_for :users, :skip => [:registrations]                                          
    as :user do
      get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'    
      put 'users' => 'devise/registrations#update', :as => 'user_registration'            
    end

And then you can make such link in your view:

= link_to "Change your password", edit_user_registration_path

Solution 3.

But sometimes, developers want to provide their custom actions that change the password. In such cases, the best option is for you to create manually a controller:

class UsersController < ApplicationController
  def edit
    @user = current_user
  end

  def update_password
    @user = User.find(current_user.id)
    if @user.update_attributes(user_params)
      # Sign in the user by passing validation in case his password changed
      sign_in @user, :bypass => true
      redirect_to root_path
    else
      render "edit"
    end
  end

  private

  def user_params
    params.required(:user).permit(:password, :password_confirmation)
  end
end

The route should be the following:

resource :user, only: [:show] do
  collection do
    patch 'update_password'
  end
end

And then proceed to implement the view, as below:

<%= form_for(@user, :url => { :action => "update_password" } ) do |f| %>
  <div class="field">
    <%= f.label :password, "Password" %><br />
    <%= f.password_field :password, :autocomplete => "off"  %>
  </div>
  <div class="field">
    <%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation %>
  </div>
  <div class="action_container">
    <%= f.submit %>
  </div>
<% end %>

To use "confirm_password" field to force user to enter old password before updating with the new one: Change @user.update_attributes(params[:user]) to @user.update_with_password(params[:user]) in the controller along with adding :current_password to the permitted parameters, then and add the following to the view code:

  <div class="field">
    <%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
    <%= f.password_field :current_password %>
  </div>

Remember, Devise models are like any model in your application. If you want to provide custom behavior, just implement new actions and new controllers. Don't try to bend Devise.
