How can I add custom fields to Devise in a Rails application?

You can add custom fields to Devise by creating a migration to add the fields to your users table and then permitting those fields in the Devise controller.

What kind of custom fields can I add?

You can add fields like 'first_name', 'last_name', or any other user-specific information you need.

How do I permit these fields in the controller?

You need to override the configure_permitted_parameters method in your ApplicationController to include your custom fields.

Can you show me an example of the migration?

Sure! You can create a migration like this: rails generate migration AddFieldsToUsers first_name:string last_name:string.
