Q:

Unauthorize error on password update Devise

I'm  working on a rails api and using devise_token_auth for the authentication, when I try to update password by hitting the /auth/password with put request it responsds with error 401 i.e. unauthorized. My server logs show me this

Started PUT "/auth/password"  Processing by
  DeviseTokenAuth::PasswordsController#update as HTML   Parameters:
  {"password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}
  Can't verify CSRF token authenticity Completed 401 Unauthorized in

routes.rb
mount_devise_token_auth_for 'User', at: 'auth' ,:controllers => { :omniauth_callbacks => 'omniauth'  }

view.html (angularjs)
<div class="container">
    <div class="row">

    <div class="row">
       <div class="col-xs-6 col-xs-offset-3 que">
           <img src="./uploads/img/web-logo.png" class="img-responsive" alt="Logo">
       </div>
    </div>
        <div class="col-xs-12 reset-pas">
            <form  name="update_pass" ng-submit="updatePassword_controller()" role="form" class="lost_reset_password">
                <p class="error_msg" ng-show="update_pass.password_confirmation.$error.passwordVerify"> 
                    Passwords are not equal!
                </p>
            <label>New password</label>
            <input type="password" name="password"  ng-minlength="8"  ng-model="updatePasswordForm.password" required="required" class="form-control">
            <span>Minimum 8 Charachters</span>
    <br>
            <label>Re-enter new password</label>

            <input type="password" name="password_confirmation"  ng-minlength="8"  ng-model="updatePasswordForm.password_confirmation" required="required" class="form-control"  password-verify="updatePasswordForm.password" >
                <button type="submit" class="btn btn-default" id="reset-submit">Save</button>
            </form>
        </div>
    </div>
</div>

controller.js
$scope.updatePassword_controller = function() {

  $auth.updatePassword($scope.updatePasswordForm)
    .then(function(resp) {
      console.log(resp)
      $location.path('/')
    })
    .catch(function(resp) {
      console.log(resp)
    });
};

Update
Note
I'm facing this issue only for password update
Update
I installed gem 'angular_rails_csrf' Now it's giving only the authorization error not the csrf attack error

A:

I simply made a condition in applicationcontroller.rb like below and it worked out . The main idea is simply to override the functionality of Devise 
        if params[:controller] == "devise_token_auth/passwords" && params[:action] == "update"

              uri               = URI.parse(request.headers.env['HTTP_REFERER'])
              query_params      = CGI.parse(uri.query)
              email             = query_params['uid'].first
              user              = User.find_by_email(email)
              user.password     = params[:password]
              user.password_confirmation = params[:password_confirmation]

              if user.save
                    render json: {message: 'Password Updated successfully', status: 200}                        
              else
                    render json: {message: 'Password Could not changed , Please contact to support Team', status: 401}
              end
        end

Although it's not the proper solution but i couldn't think of anyother one . So please bear with me .In it we're fetching email from url
