# __toString()

View source (opens new window)
Returns
# attributeLabels()
Returns the attribute labels.
Attribute labels are mainly used for display purpose. For example, given an attribute
firstName, we can declare a label First Name which is more user-friendly and can
be displayed to end users.
By default an attribute label is generated using generateAttributeLabel() (opens new window). This method allows you to explicitly specify attribute labels.
Note, in order to inherit labels defined in the parent class, a child class needs to
merge the parent labels with child labels using functions such as array_merge().
View source (opens new window)
Returns
array (opens new window) – Attribute labels (name => label)
# behaviors()
Returns a list of behaviors that this component should behave as.
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:
'behaviorName' => [
'class' => 'BehaviorClass',
'property1' => 'value1',
'property2' => 'value2',
]
Note that a behavior class must extend from \craft\models\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() (opens new window)
or be detached using detachBehavior() (opens new window). Anonymous behaviors can not be retrieved or detached.
Behaviors declared in this method will be attached to the component automatically (on demand).
View source (opens new window)
Returns
array (opens new window) – The behavior configurations.

# Protected Methods
| Method | Description |
|---|---|
| defineRules() | Returns the validation rules for attributes. |
| extractFieldsFor() (opens new window) | Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "id". |
| extractRootFields() (opens new window) | Extracts the root field names from nested fields. |
| resolveFields() (opens new window) | Determines which fields can be returned by toArray() (opens new window). |
# defineRules()
- Since
- 3.4.0
Returns the validation rules for attributes.
See rules() for details about what should be returned.
Models should override this method instead of rules() so EVENT_DEFINE_RULES handlers can modify the class-defined rules.

|---|---|
DEFAULT_PLACEMENT_BEGINNING | |
DEFAULT_PLACEMENT_END | |
SCENARIO_DEFAULT | The name of the default scenario. |
