MigrateController extends BaseMigrateController
in package

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

Since 2.0.10 you can use namespaced migrations. In order to enable this feature you should configure [[migrationNamespaces]] property for the controller at application configuration:

return [
    'controllerMap' => [
        'migrate' => [
            'class' => 'yii\console\controllers\MigrateController',
            'migrationNamespaces' => [
                'app\migrations',
                'some\extension\migrations',
            ],
            //'migrationPath' => null, // allows to disable not namespaced migration completely
        ],
    ],
];

whether to display help information about current command.

Tags
since
2.0.10

$helpSummary read-only

public string $helpSummary

$id

public string $id

the ID of this controller.

$interactive

public bool $interactive = true

whether to run the command interactively.

$layout

public string|null|false $layout

$migrationNamespaces

public array<string|int, mixed> $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. This corresponds with the autoloading conventions of Yii.

For example:

[
    'app\migrations',
    'some\extension\migrations',
]

migrationPath

$migrationPath

public string|array<string|int, mixed>|null $migrationPath = ['@app/migrations']

the directory containing the migration classes. This can be either a path alias or a directory path.

Migration classes located at this path should be declared without a namespace. Use [[migrationNamespaces]] property in case you are using namespaced migrations.

If you have set up [[migrationNamespaces]], you may set this field to null in order to disable usage of migrations that are not namespaced.

Since version 2.0.12 you may also specify an array of migration paths that should be searched for migrations to load. This is mainly useful to support old extensions that provide migrations without namespace and to adopt the new feature of namespaced migrations while keeping existing migrations.

In general, to load migrations from different locations, [[migrationNamespaces]] is the preferable solution as the migration name contains the origin of the migration in the history, which is not the case when using multiple migration paths.

actionCreate()

Creates a new migration.

public actionCreate(string $name) : mixed

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.

Parameters
$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.

Tags
throws
Exception

if the name argument is invalid.

actionDown()

Downgrades the application by reverting old migrations.

public actionDown([int|string $limit = 1 ]) : int

yii migrate/down 3   # revert the last 3 migrations
yii migrate/down all # revert all migrations
Parameters
$limit : int|string = 1

Tags
throws
Exception

if the number of the steps specified is less than 1.

Return values
int

the status of the action execution. 0 means normal, other values mean abnormal.

actionTo()

Upgrades or downgrades till the specified version.

public actionTo(string $version) : mixed

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
Parameters
$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.

{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}

Parameters
$name : string

the name of the behavior.

$behavior : string|array<string|int, mixed>|Behavior

the behavior configuration. This can be one of the following:

  • a [[Behavior]] object

Return values
bool

whether the action should continue to be executed.

behaviors()

Returns a list of behaviors that this component should behave as.

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from [[Behavior]]. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using [[getBehavior()]] or be detached using [[detachBehavior()]]. Anonymous behaviors can not be retrieved or detached.

render()

Renders a view and applies layout if available.

public render(string $view[, array<string|int, mixed> $params = [] ]) : string

The view to be rendered can be specified in one of the following formats:

  • path alias (e.g. "@app/views/site/index");
  • absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the [[Application::viewPath|view path]] of the application.
  • absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the [[Module::viewPath|view path]] of [[module]].
  • relative path (e.g. "index"): the actual view file will be looked for under [[viewPath]].

To determine which layout should be applied, the following two steps are conducted:

  1. In the first step, it determines the layout name and the context module:
  • If [[layout]] is specified as a string, use it as the layout name and [[module]] as the context module;
  • If [[layout]] is null, search through all ancestor modules of this controller and find the first module whose [[Module::layout|layout]] is not null. The layout and the corresponding module are used as the layout name and the context module, respectively. If such a module is not found or the corresponding layout is not a string, it will return false, meaning no applicable layout.
  1. In the second step, it determines the actual layout file according to the previously found layout name and context module. The layout name can be:
  • a path alias (e.g. "@app/views/layouts/main");
  • an absolute path (e.g. "/main"): the layout name starts with a slash. The actual layout file will be looked for under the [[Application::layoutPath|layout path]] of the application;
  • a relative path (e.g. "main"): the actual layout file will be looked for under the [[Module::layoutPath|layout path]] of the context module.

If the layout name does not contain a file extension, it will use the default one .php.

Parameters
$view : string

the view name.

$params : array<string|int, mixed> = []

the parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.
