[英]Phalcon PHP: determine if create or update in model validation method
I've created a Model in Phalcon. 我已经在Phalcon中创建了一个模型。 In it, I have a validation() method.
在其中,我有一个validate()方法。 On create of a record, I want to make sure that a record is getting a name, but I don't want that to be required on update.
创建记录时,我要确保记录获得名称,但是我不希望更新时需要该名称。 How can I determine that with Phalcon?
我如何用Phalcon确定呢?
It is described better in the Phalcon's docs . 在Phalcon的文档中对其进行了更好的描述。
class Robots extends \Phalcon\Mvc\Model
{
public function initialize()
{
//Skips fields/columns on both INSERT/UPDATE operations
$this->skipAttributes(array('year', 'price'));
//Skips only when inserting
$this->skipAttributesOnCreate(array('created_at'));
//Skips only when updating
$this->skipAttributesOnUpdate(array('modified_in'));
}
}
If you have something more complex and want to use the same 'validation' method for both creates and updates you can do this: 如果您有更复杂的东西,并且想要使用相同的“验证”方法进行创建和更新,则可以执行以下操作:
public function beforeValidationOnCreate()
{
$this->_isCreate = 1;
}
public function beforeValidationOnUpdate()
{
$this->_isCreate = 0;
}
public function validation()
{
if ($this->_isCreate) {
// ...
} else {
// ...
}
}
You can do your validations within a function called beforeValidationOnCreate or beforeCreate and it gets hit only on Creation and not updating 您可以在一个名为beforeValidationOnCreate或beforeCreate的函数中进行验证,并且仅在创建时才会命中它,而不会更新
public function beforeValidationOnCreate()
{
//Do the validations
}
or 要么
class MyModel extends \Phalcon\Mvc\Model
{
public function beforeCreate()
{
//Do the validations
}
}
