## Property Details

$compact public property (available since version 2.0.13)

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.

public boolean $compact = false
$defaultAction public property

The default command action.

public string $defaultAction = 'up'
$migrationNamespaces public property (available since version 2.0.10)

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',
    ]

See also $migrationPath.

public array $migrationNamespaces = []
$migrationPath public property

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.

See also $migrationNamespaces.

public string|array $migrationPath = ['@app/migrations']
$templateFile public property

The template file for generating new migrations. This can be either a path alias (e.g. "@app/migrations/template.php") or a file path.

public string $templateFile = null

## Method Details

actionCreate() public method

Creates a new migration.

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 void actionCreate ( $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.
throws | yii\console\Exception | if the name argument is invalid.

actionDown() public method

Downgrades the application by reverting old migrations.

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 integer actionDown ( $limit = 1 )
$limit | integer|string | The number of migrations to be reverted. Defaults to 1, meaning the last applied migration will be reverted. When value is "all", all migrations will be reverted.
return | integer | The status of the action execution. 0 means normal, other values mean abnormal.
throws | yii\console\Exception | if the number of the steps specified is less than 1.

actionFresh() public method (available since version 2.0.13)

Drops all tables and related constraints. Starts the migration from the beginning.

    yii migrate/fresh

public void actionFresh ( )

actionHistory() public method

Displays the migration history.

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 void actionHistory ( $limit = 10 )
$limit | integer|string | The maximum number of migrations to be displayed. If it is "all", the whole migration history will be displayed.
throws | yii\console\Exception | if invalid limit value passed

actionMark() public method

Modifies the migration history to the specified version.

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/mark app\migrations\M101129185401CreateUser # using full namespace name
    yii migrate/mark m000000_000000_base # reset the complete migration history

public integer actionMark ( $version )
$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. You may specify the name `m000000_000000_base` to set the migration history to a state where no migration has been applied.
return | integer | CLI exit code
throws | yii\console\Exception | if the version argument is invalid or the version cannot be found.

actionNew() public method

Displays the un-applied new migrations.

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 void actionNew ( $limit = 10 )
$limit | integer|string | The maximum number of new migrations to be displayed. If it is `all`, all available new migrations will be displayed.
throws | yii\console\Exception | if invalid limit value passed

actionRedo() public method

Redoes the last few migrations.

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 integer actionRedo ( $limit = 1 )
$limit | integer|string | The number of migrations to be redone. Defaults to 1, meaning the last applied migration will be redone. When equals "all", all migrations will be redone.
return | integer | The status of the action execution. 0 means normal, other values mean abnormal.
throws | yii\console\Exception | if the number of the steps specified is less than 1.

actionTo() public method

Upgrades or downgrades till the specified version.

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 void actionTo ( $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.
throws | yii\console\Exception | if the version argument is invalid.

actionUp() public method

Upgrades the application by applying new migrations.

For example,

    yii migrate     # apply all new migrations
    yii migrate 3   # apply the first 3 new migrations

public integer actionUp ( $limit = 0 )
$limit | integer | The number of new migrations to be applied. If 0, it means applying all available new migrations.
return | integer | The status of the action execution. 0 means normal, other values mean abnormal.
