Manages application migrations.
A migration means a set of persistent changes to the application environment that is shared among different developers. For example, in an application backed by a database, a migration may refer to a set of changes to the database, such as creating a new table, adding a new table column.
This command provides support for tracking the migration history, upgrading or downloading with migrations, and creating new migration skeletons.
The migration history is stored in a database table named as $migrationTable. The table will be automatically created the first time this command is executed, if it does not exist. You may also manually create it as follows:
CREATE TABLE migration (
version varchar(180) PRIMARY KEY,
apply_time integer
)
Below are some common usages of this command:
# creates a new migration named 'create_user_table'
yii migrate/create create_user_table
# applies ALL new migrations
yii migrate
# reverts the last applied migration
yii migrate/down
