PHP 클래스 yii\console\controllers\MigrateController

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 ~~~ 파일 보기 프로젝트 열기: yiisoft/yii2 1 사용 예제들

$db		the DB connection object or the application component ID of the DB connection to use when applying migrations. Starting from version 2.0.3, this can also be a configuration array for creating the object.
$fields		column definition strings used for creating migration code. The format of each definition is COLUMN_NAME:COLUMN_TYPE:COLUMN_DECORATOR. Delimiter is ,. For example, --fields="name:string(12):notNull:unique" produces a string column of size 12 which is not null and unique values. Note: primary key is added automatically and is named id by default. If you want to use another name you may specify it explicitly like --fields="id_key:primaryKey,name:string(12):notNull:unique"
$generatorTemplateFiles		a set of template paths for generating migration code automatically. The key is the template type, the value is a path or the alias. Supported types are: - create_table: table creating template - drop_table: table dropping template - add_column: adding new column template - drop_column: dropping column template - create_junction: create junction template
$migrationTable		the name of the table for keeping applied migration information.
