Explain database migrations in Rails
← All Ruby on Rails questions
Re-explain
Migrations are Ruby classes that allow you to evolve your database schema over time in a consistent way. They provide:
- Version control for database schema
- Team collaboration on schema changes
- Database-agnostic schema modifications
- Rollback capabilities
class CreateUsers < ActiveRecord::Migration[7.0]
def change
create_table :users do |t|
t.string :email
t.timestamps
end
end
end
