assign a default value for column ruby on rails

i have created a migration for user, later on i added column to my model using

rails generate migration add_usertype_to_users usertype:string which generates following

class AddUsertypeToUsers < ActiveRecord::Migration
  def change
    add_column :users, :usertype, :string
  end
end

now i am trying to assign default value to this usertype as basic.

where it would be better to assign default to this column, i.e inside migration, inside my model, or do i have to create new migration? all the examples i came up with are giving default value at time of creating migration when creating column, please let me know the right way. Thanks in advance

Setting default value in migration is better.

You can define default value like this

class AddUsertypeToUsers < ActiveRecord::Migration
  def change
    add_column :users, :usertype, :string, default: 'value'
  end
end
