  • Do the following check the routes using rake Routes and then glue here for us to look. rake Routes

You need to add the route in config/Routes.Rb

Sample::Application.routes.draw do
  #outras rotas...

  resource :usuario #adicione essa linha
end

and controller name always in plural ex.: User

  • Dude I’ve already added :|

  • Rails.application.Routes.draw do Resources :user root 'user#index' get '/login' => 'user#index'

  • is "user" and not "user"

  • but because it has to be plural ?

  • Didn’t work ..

  • Resources for plural and Resource for singular Ex.: Resources :users or Resource :user controller name is singular so use Resource* instead of Resources*

  • normally if you use the controller name in the plural, you can put it in the plural and do as I had done before, or simply use the singular route

  • Let’s go continue this discussion in chat.

    I renamed the controller and it worked .
