How to set default value when creating a Rails model?

Question

I'd like to create the following and set is_seen to false explicitly.

rails g model notification body: text, user_id: integer, is_seen: boolean

I know how to update this alter via a change_column but how would I set this to false at this point?

This is not for a migration but from creating a model.

You can't set the default value while creating the model/migration at that point.

You have to create/edit the migration file and change the corresponding line to something like this:

add_column :table, :is_seen, :boolean, default: false
