How to add default value in Rails migration?<\/p>\n

In Ruby on Rails, migrations are used to make changes to the database schema. They allow you to create, modify, or delete tables and columns in your database. One common requirement when creating or modifying columns in Rails migrations is to set a default value for the column. Fortunately, Rails provides a simple method to achieve this. <\/p>\n

To add a default value in a Rails migration, you can use the `default` option when defining a column. Let’s take a look at an example:<\/p>\n

“`
\nclass AddDefaultValueToUsers < ActiveRecord::Migration[6.1]
\n def change
\n change_column :users, :status, :string, default: ‘active’
\n end
\nend
\n“`<\/p>\n

In the above example, we’re adding a default value of ‘active’ to the `status` column in the `users` table. By calling `change_column` and passing the table name, column name, column type, and the `default` option, Rails will automatically create a migration file that will update the column and set the default value.<\/p>\n
