How do i use a username instead of an email?

I am watching the series and really enjoying it. I am up to Part 11 where you create the user model. Is there a way to use a username instead of email?

Hey Ookma-Kyi

Yes you can, you just need to add a user name column to your users model with a migration:
add_column :users, :user_name, :string

In your user model make sure you add a validation so it is present and unique:

validates :user_name, presence: true, uniqueness: true

In your signup form make sure you add a user_name field:

<%= f.text_field :user_name %>

And then when the user signs in, in your create session controller action search for the user by user_name rather than email:

User.find_by(user_name: params[:user][:user_name])

Hope that helps!

Thanks OP for your reply. I also would like to know more how to add username instead of an email.
