Change Login [Gem Devise Ruby On Rails]

Question

Gem Design creates a login system with email and password. How do I change the form of email login to a code, ie instead of the user login by email it enter with a number or name?

Answer 1

Create a Migration to add the user name:

$ rails generate migration add_username_to_users username:string

Run the Migration:

$ rake db:migrate

Change the file /config/initializers/Devise.Rb by swapping :email for :username

config.authentication_keys = [ :username ]

Finally, change your view:

<li><%= f.label :username %> <%= f.text_field :username %></li>

I haven’t had to do that yet, but there’s this wiki from Twitter that demonstrates how to use a username (or code) to log in.
