Migrations

Padrino provides generator for quickly generating new migrations to change or manipulate the database schema. These migrations generated will be tailored towards the ORM chosen when generating the application.

Run migration generators from the root of a Padrino project, the folder that contains config/boot.rb. They read project settings, such as the ORM, from the .components file that the project generator creates, so they will not work in a project without it.

Using the migration generator is as simple as:

$ padrino g migration AddFieldsToUsers
$ padrino g migration RemoveFieldsFromUsers

You can also specify desired columns to be added to the migration file:

$ padrino g migration AddFieldsToUsers last_login:datetime crypted_password:string
$ padrino g migration RemoveFieldsFromUsers password:string ip_address:string

The migration generator will then construct the migration file according to your ORM component chosen within db/migrate/xxx_add_fields_to_users.rb including the columns specified in the command.

You can destroy migrations that you created via the destroy option and setting it to true. Default is false.

$ padrino g migration AddFieldsToUsers -d
