Properties
$action
public
Action|null
$action
the action that is currently being executed. This property will be set by [[run()]] when it is called by [[Application]] to run an action.
$behaviors read-only
public
array<string|int, Behavior>
$behaviors
List of behaviors attached to this component.
$color
public
bool|null
$color
whether to enable ANSI color in the output. If not set, ANSI color will only be enabled for terminals that support it.
$compact
public
bool
$compact
= false
indicates whether the console output should be compacted. If this is set to true, the individual commands ran within the migration will not be output to the console. Default is false, in other words the output is fully verbose by default.
Tags
$defaultAction
public
string
$defaultAction
= 'up'
the default command action.
$help
public
bool
$help
= false
whether to display help information about current command.
Tags
$help read-only
public
string
$help
$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
the name of the layout to be applied to this controller's views. This property mainly affects the behavior of [[render()]]. Defaults to null, meaning the actual layout value should inherit that from [[module]]'s layout value. If false, no layout will be applied.
$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',
]
Tags
$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

Return values
stringattachBehavior()
Attaches a behavior to this component.
public
attachBehavior(string $name, string|array<string|int, mixed>|Behavior $behavior) : Behavior

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
- a string specifying the behavior class
- an object configuration array that will be passed to [[Yii::createObject()]] to create the behavior object.
Tags
Return values
Behavior —the behavior object
attachBehaviors()
Attaches a list of behaviors to the component.
public
attachBehaviors(array<string|int, mixed> $behaviors) : mixed
Each behavior is indexed by its name and should be a [[Behavior]] object, a string specifying the behavior class, or an configuration array for creating the behavior.
Parameters
- $behaviors : array<string|int, mixed>
-
list of behaviors to be attached to the component
Tags
beforeAction()
This method is invoked right before an action is to be executed (after all possible filters.) It checks the existence of the [[migrationPath]].
public
beforeAction(Action $action) : bool
Parameters
- $action : Action
-
the action to be executed.
Tags
Return values
bool —whether the action should continue to be executed.
behaviors()
Returns a list of behaviors that this component should behave as.
public
behaviors() : array<string|int, mixed>
Child classes may override this method to specify the behaviors they want to behave as.
The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

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:
- 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.
- 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.
