undefined local variable or method `root_path' for #<#:0xc0be918>

Question

I was trying to work the Devise confirmable email, but now errors appear and it does not work (before the changes, it worked well).

If anyone can help me identify it, I'd appreciate it.

I just was trying: http://www.bogotobogo.com/RubyOnRails/RubyOnRails_Devise_Authentication_Sending_Confirmation_Email.php

NameError in Registrations#create

undefined local variable or method `root_path' for #<#:0xc0be918> Did you mean? font_path

In the view mark, after try register:

 <li><%= link_to "Start", root_path %></li>

In the route:

Rails.application.routes.draw do

   devise_for :usuarios, controllers: {registrations: 'registrations', omniauth_callbacks: "omniauth_callbacks"}

   root 'welcome#index'
   get "welcome/index"

   get ':controller(/:action(/:id))(.:format)'
   post ':controller(/:action(/:id))(.:format)'

end

The error happens in your mailer. You can't use _path helpers in Mailers (since it would generate a URL like "/", which is not useful when clicked in mails).

Instead, you have to use the _url helpers. Changing your mailer to use root_url should be enough, assuming you have set config.action_mailer.default_url_options = { host: 'example.com' } (should be in config/application.rb).

A similar error was experienced by me. But in my case I had mistakenly commented out

    #root 'welcome#index'

On un-commenting things returned to normal.

    root 'welcome#index'
