Laravel model validation

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',
    ];
}
