rails. update_attributes is not executed, or is it executed, but strange?

Question

HTML

Hello. Using devise, I want to update user from my controller. But everything is very strange.
routes.rb

get 'users/:id' => 'users#show', :as => :user
  get 'edit'      => 'users#edit'
  patch "edit" => "users#update"

  devise_for :users, :path => '', controllers: {
    sessions: 'custom_sessions',
    registrations: 'custom_registrations'
  }, :path_names => { :sign_up => 'signup',
                      :sign_out => 'logout',
                      :sign_in => 'login',
                      :edit    => nil }
  resources :notes
  root 'notes#index'

users_controller.rb

def edit
    @user = current_user
  end

  def update
    @user = User.find(current_user.id)
    if @user.update_attributes(user_params)
      flash[:notice] = "Profile successfully updated"
      redirect_to root_path
    else
      render 'edit'
    end
  end

  private

  def user_params
    params[:user].permit(:name)
  end

And the form itself:

-provide(:title, "#{@user.name}")
=form_for @user, url: edit_path, method: :patch do |f|
  =f.text_field :name
  =f.submit "update"

In general, what is happening.
localhost:3000/edit, gives the correct page

We enter new data into the form, press submit and what happens is what is written in the controller as else, that is, render 'edit', BUT, it renders a new page and shows new data in the title, then -there is locally on edit.html.haml #{@user.name} this has been updated, but not in the database.

What am I doing wrong?
Here's another screenshot if it helps.

Answer 1

Most likely a validation error. By default, devise requires you to enter your current password to confirm changes.

Thank you all, all rashil! His own forgetfulness played a cruel joke.)
