Property Details
Name of the catalog (database) that this table belongs to. Defaults to null, meaning no catalog (or the current database).
Method Details
Defined in: yii\base\BaseObject::__call()
Calls the named method which is not a class method.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
| public mixed __call ( $name, $params ) | ||
| $name | string |
The method name |
| $params | array |
Method parameters |
| return | mixed |
The method return value |
|---|---|---|
| throws | yii\base\UnknownMethodException |
when calling unknown method |
public function __call($name, $params)
{
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$confighere. - call the parent implementation at the end of the constructor.
| public void __construct ( $config = [] ) | ||
| $config | array |
Name-value pairs that will be used to initialize the object properties |
public function __construct($config = [])
{
if (!empty($config)) {
Yii::configure($this, $config);
}
$this->init();
}
Defined in: yii\base\BaseObject::__get()
Returns the value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $object->property;.
See also __set().
| public mixed __get ( $name ) | ||
| $name | string |
The property name |
| return | mixed |
The property value |
|---|---|---|
| throws | yii\base\UnknownPropertyException |
if the property is not defined |
| throws | yii\base\InvalidCallException |
if the property is write-only |
public function __get($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter();
} elseif (method_exists($this, 'set' . $name)) {
throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
}
throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
Defined in: yii\base\BaseObject::__isset()
Checks if a property is set, i.e. defined and not null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($object->property).
Note that if the property is not defined, false will be returned.
| public boolean __isset ( $name ) | ||
| $name | string |
The property name or the event name |
| return | boolean |
Whether the named property is set (not null). |
|---|---|---|
public function __isset($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter() !== null;
}
return false;
}
Defined in: yii\base\BaseObject::__set()
Sets value of an object property.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $object->property = $value;.
See also __get().
| public void __set ( $name, $value ) | ||
| $name | string |
The property name or the event name |
| $value | mixed |
The property value |
| throws | yii\base\UnknownPropertyException |
if the property is not defined |
|---|---|---|
| throws | yii\base\InvalidCallException |
if the property is read-only |
public function __set($name, $value)
{
$setter = 'set' . $name;
if (method_exists($this, $setter)) {
$this->$setter($value);
} elseif (method_exists($this, 'get' . $name)) {
throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
} else {
throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($object->property).
Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.
| public void __unset ( $name ) | ||
| $name | string |
The property name |
| throws | yii\base\InvalidCallException |
if the property is read only. |
|---|---|---|
public function __unset($name)
{
$setter = 'set' . $name;
if (method_exists($this, $setter)) {
$this->$setter(null);
} elseif (method_exists($this, 'get' . $name)) {
throw new InvalidCallException('Unsetting read-only property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::canGetProperty()
Returns a value indicating whether a property can be read.
A property is readable if:
- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVarsis true);
See also canSetProperty().
| public boolean canGetProperty ( $name, $checkVars = true ) | ||
| $name | string |
The property name |
| $checkVars | boolean |
Whether to treat member variables as properties |
| return | boolean |
Whether the property can be read |
|---|---|---|
public function canGetProperty($name, $checkVars = true)
{
return method_exists($this, 'get' . $name) || $checkVars && property_exists($this, $name);
}
Defined in: yii\base\BaseObject::canSetProperty()
Returns a value indicating whether a property can be set.
A property is writable if:
- the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVarsis true);
See also canGetProperty().
| public boolean canSetProperty ( $name, $checkVars = true ) | ||
| $name | string |
The property name |
| $checkVars | boolean |
Whether to treat member variables as properties |
| return | boolean |
Whether the property can be written |
|---|---|---|
public function canSetProperty($name, $checkVars = true)
{
return method_exists($this, 'set' . $name) || $checkVars && property_exists($this, $name);
}
::class instead.
Defined in: yii\base\BaseObject::className()
Returns the fully qualified name of this class.

{
return get_called_class();
}
Defined in: yii\db\TableSchema::fixPrimaryKey()
Manually specifies the primary key for this table.
| public void fixPrimaryKey ( $keys ) | ||
| $keys | string|array |
The primary key (can be composite) |
| throws | yii\base\InvalidArgumentException |
if the specified key cannot be found in the table. |
|---|---|---|
public function fixPrimaryKey($keys)
{
$keys = (array) $keys;
$this->primaryKey = $keys;
foreach ($this->columns as $column) {
$column->isPrimaryKey = false;
}
foreach ($keys as $key) {
if (isset($this->columns[$key])) {
$this->columns[$key]->isPrimaryKey = true;
} else {
throw new InvalidArgumentException("Primary key '$key' cannot be found in table '{$this->name}'.");
}
}
}

| public yii\db\ColumnSchema|null getColumn ( $name ) | ||
| $name | string |
Column name |
| return | yii\db\ColumnSchema|null |
Metadata of the named column. Null if the named column does not exist. |

| return | boolean |
Whether the method is defined |
|---|---|---|
public function hasMethod($name)

- the class has a member variable with the specified name (when
$checkVarsis true);
See also:
| public boolean hasProperty ( $name, $checkVars = true ) | ||

| $checkVars | boolean |
Whether to treat member variables as properties |
| return | boolean |
