Usage
This extension provides support for Yii1 Model and ActiveRecord automatic attributes typecast.
It is performed via usage of \yii1tech\model\typecast\TypecastBehavior behavior.
It should be attached to \CModel or \CActiveRecord descendant.
For example:
Tip: you may leave
\yii1tech\model\typecast\TypecastBehavior::$attributeTypesblank - in this case its value will be detected automatically: for ActiveRecord - based on owner DB table schema, for regular model - based validation rules.
In the above example attribute typecasting will be automatically performed in following cases:
- after model successful validation
- after model successful saving
- after model retrieval from Database
For example:
You can manually trigger attribute typecasting anytime invoking \yii1tech\model\typecast\TypecastBehavior::typecastAttributes() method:
JSON Typecasting
This behavior allows automatic conversion of array or traversable objects into JSON string on model saving. For example:
Note: such conversion will take place even, if there is no direct attribute type specification.
You can typecast JSON column value either to plain array or \ArrayObject instance.
Plain arrays consume less memory, but writing of its particular internal keys will not work.
\ArrayObject allows free operation over internal keys, but you should note that its value always passed by reference.
DateTime Typecasting
This behavior allows automatic conversion of \DateTime instances into ISO datetime string on model saving.
For example:
In case you store the dates using integer Unix timestamp, you can use \yii1tech\model\typecast\TypecastBehavior::TYPE_TIMESTAMP for correct
conversion. For example:
This extension also supports nesbot/carbon package.
In order to convert dates to \Carbon\Carbon you should use following types:
\yii1tech\model\typecast\TypecastBehavior::TYPE_DATETIME_CARBON\yii1tech\model\typecast\TypecastBehavior::TYPE_TIMESTAMP_CARBON
Custom Typecasting
You may specify any custom typecasting for the attribute using a callable as a type specification at \yii1tech\model\typecast\TypecastBehavior::$attributeTypes.
For example:
