__construct()

Constructor

View source

Arguments

• $config (array)

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(). 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().

Method	Description
defineBehaviors()	Returns the behaviors to attach to this class.
defineRules()	Returns the validation rules for attributes.
extractFieldsFor()	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()	Extracts the root field names from nested fields.
resolveFields()	Determines which fields can be returned by toArray().

defineBehaviors()

Since

4.0.0

Returns the behaviors to attach to this class.

See behaviors() for details about what should be returned.

Models should override this method instead of behaviors() so EVENT_DEFINE_BEHAVIORS handlers can modify the class-defined behaviors.

defineRules()

Since

3.4.0

Returns the validation rules for attributes.

See rules() for details about what should be returned.
