trait class 的定义
namespace App\Library\Model;
use Illuminate\Contracts\Validation\Factory;
trait WithValidates
{
// protected $rules = [];
// protected $customMessages = [];
// protected $customAttributes = [];
/**
* @param $validator
*
* @return array
*/
public function validateWith($validator)
{
if (is_array($validator)) {
$validator = $this->getValidator($this->attributes, $validator);
}
$validator->after(function ($validate) {
return call_user_func('self::afterValidate', $validate);
});
return $validator->validate();
}
protected function getValidator($data, $rules = [], $messages = [], $customAttributes = [])
{
return $this->getValidationFactory()->make($data, $rules ?: [], $messages ?: [], $customAttributes ?: []);
}
/**
* Get a validation factory instance.
* @return Factory
*/
protected function getValidationFactory()
{
return app(Factory::class);
}
/**
* @param null $rules
* @param null $messages
* @param null $customAttributes
*
* @return array
*/
public function validate($rules = [], $messages = [], $customAttributes = [])
{
$validator = $this->getValidator(
$this->attributes,
$rules ?: $this->rules,
$messages ?: $this->customMessages,
$customAttributes ?: $this->customAttributes
);
$validator->after(function ($validate) {
return call_user_func('self::afterValidate', $validate);
});
return $validator->validate();
}
/**
* @param $validator
*/
protected function afterValidate($validator)
{
}
}
简单使用
namespace App;
use Illuminate\Database\Eloquent\Model;
class Tooltip extends Model
{
use WithValidates;
protected $rules = [
'category' => 'string|required|max:64',
'field' => 'string|required|max:64',
'index' => 'integer|nullable',
'description' => 'string|nullable',
];
protected $fillable = [
'category',
'field',
'index',
'description',
];
}
abstract class 的方式来使用
abstract class BasicModel extends Model
{
use WithValidates;
protected $perPage = 10;
protected $rules = [];
protected $customMessages = [];
protected $customAttributes = [];
}
model file usage
namespace App;
use App\Library\Model\BasicModel;
class Tooltip extends BasicModel
{
protected $rules = [
'category' => 'string|required|max:64',
'field' => 'string|required|max:64',
'index' => 'integer|nullable',
'description' => 'string|nullable',
];
protected $fillable = [
'category',
'field',
'index',
'description',
];
}
