Свойство Type Description
$defaultAction the default command action.
$migrationNamespaces list of namespaces containing the migration classes. Migration namespaces should be resolvable as a path alias if prefixed with @, e.g. if you specify the namespace app\migrations, the code Yii::getAlias('@app/migrations') should be able to return the file path to the directory this namespace refers to. For example: php [ 'app\migrations', 'some\extension\migrations', ]
$migrationPath the directory containing the migration classes. This can be either a path alias or a directory path. If you have set up [[migrationNamespaces]], you may set this field to null in order to disable usage of migrations that are not namespaced.
$templateFile the template file for generating new migrations. This can be either a path alias (e.g. "@app/migrations/template.php") or a file path.

Method Details

actionCreate() public méthode

This command creates a new migration using the available migration template. After using this command, developers should modify the created migration skeleton by filling up the actual migration logic. yii migrate/create create_user_table In order to generate a namespaced migration, you should specify a namespace before the migration's name. Note that backslash (\) is usually considered a special character in the shell, so you need to escape it properly to avoid shell errors or incorrect behavior. For example: yii migrate/create 'app\\migrations\\createUserTable' In case [[migrationPath]] is not set and no namespace is provided, the first entry of [[migrationNamespaces]] will be used.
public actionCreate ( string $name )
$name string the name of the new migration. This should only contain letters, digits, underscores and/or backslashes. Note: If the migration name is of a special form, for example create_xxx or drop_xxx, then the generated migration file will contain extra code, in this case for creating/dropping tables.

actionDown() public méthode

For example, yii migrate/down # revert the last migration yii migrate/down 3 # revert the last 3 migrations yii migrate/down all # revert all migrations
public actionDown ( integer $limit = 1 ) : integer
$limit integer the number of migrations to be reverted. Defaults to 1, meaning the last applied migration will be reverted.
Résultat integer the status of the action execution. 0 means normal, other values mean abnormal.

actionHistory() public méthode

This command will show the list of migrations that have been applied so far. For example, yii migrate/history # showing the last 10 migrations yii migrate/history 5 # showing the last 5 migrations yii migrate/history all # showing the whole history
public actionHistory ( integer $limit = 10 )
$limit integer the maximum number of migrations to be displayed. If it is "all", the whole migration history will be displayed.

actionMark() public méthode

No actual migration will be performed. yii migrate/mark 101129_185401 # using timestamp yii migrate/mark m101129_185401_create_user_table # using full name yii migrate/to app\migrations\M101129185401CreateUser # using full namespace name
public actionMark ( string $version ) : integer
$version string the version at which the migration history should be marked. This can be either the timestamp or the full name of the migration.
Résultat integer CLI exit code

actionNew() public méthode

This command will show the new migrations that have not been applied. For example, yii migrate/new # showing the first 10 new migrations yii migrate/new 5 # showing the first 5 new migrations yii migrate/new all # showing all new migrations
public actionNew ( integer $limit = 10 )
$limit integer the maximum number of new migrations to be displayed. If it is `all`, all available new migrations will be displayed.

actionRedo() public méthode

This command will first revert the specified migrations, and then apply them again. For example, yii migrate/redo # redo the last applied migration yii migrate/redo 3 # redo the last 3 applied migrations yii migrate/redo all # redo all migrations
public actionRedo ( integer $limit = 1 ) : integer
$limit integer the number of migrations to be redone. Defaults to 1, meaning the last applied migration will be redone.
Résultat integer the status of the action execution. 0 means normal, other values mean abnormal.

actionTo() public méthode

Can also downgrade versions to the certain apply time in the past by providing a UNIX timestamp or a string parseable by the strtotime() function. This means that all the versions applied after the specified certain time would be reverted. This command will first revert the specified migrations, and then apply them again. For example, yii migrate/to 101129_185401 # using timestamp yii migrate/to m101129_185401_create_user_table # using full name yii migrate/to 1392853618 # using UNIX timestamp yii migrate/to "2014-02-15 13:00:50" # using strtotime() parseable string yii migrate/to app\migrations\M101129185401CreateUser # using full namespace name
public actionTo ( string $version )
$version string either the version name or the certain time value in the past that the application should be migrated to. This can be either the timestamp, the full name of the migration, the UNIX timestamp, or the parseable datetime string.

actionUp() public méthode

For example, yii migrate # apply all new migrations yii migrate 3 # apply the first 3 new migrations
public actionUp ( integer $limit ) : integer
$limit integer the number of new migrations to be applied. If 0, it means applying all available new migrations.
Résultat integer the status of the action execution. 0 means normal, other values mean abnormal.
