Question

I’m trying to show the data from the user through a form so he can be able to edit any field. I’m using simple_form for this, and devise for authentication purposes.
I keep getting the undefined method user_path error.

This is my controller

class HomeController < ApplicationController
 before_filter :authenticate_user!
 def index
 #Mostramos menu de opciones
 end

 def perfil
   @user = User.find(current_user.id)
 end

 def editar
   @user = User.find(current_user.id)
 end

end

The view for perfil.html.erb

<h1>showing user data</h1>
<%= simple_form_for @user do |f| %>
  <%= f.input :nombre %>
  <%= f.input :username %>
  <%= f.input :rut %>
  <%= f.input :ciudad %>
  <%= f.input :direccion %>
  <%= f.input :groupId %>
  <%= f.button :submit %>
<% end %>

<%= link_to "Editar datos", :action => :editar %>
<br>
<%= link_to "Volver", :action => :index %>

And my routes file

devise_for :users
match "perfil" => "home#perfil"
match "editar" => "home#editar"

The error is around this line in the view <%= simple_form_for @user do |f| %>
I’ve been searching for guides or insights on what I’m doing wrong (I’m almost sure is something bad done or missing in routes.rb). Any insight would be much appreciated.

<%= simple_form_for @user do |f| %>

This would post to the form to users_controller controller and action depending on the context. devise_for :users does not generate that controller for you, instead you have registrations_controller available and in fact, you don’t need to create the edit form, there’s already one available at url users/edit for the current user.

To customize the default templates, run rails generate devise:views and take a look at app/views/devise.
