【唐诗】《同從弟銷南齋玩月憶山陰崔少府》 王昌齡：高臥南齋時，開帷月初吐。清輝淡水木，演漾在窗戶。苒苒幾盈虛，澄澄變今古。美人清江畔，是夜越吟苦。千里其如何，微風吹蘭杜。

1. Print the current model

Plaintext
api\modules\v1\models\PlanTask Object
(
    [_attributes:yii\db\BaseActiveRecord:private] => Array
        (
            [id] => 3
            [group_id] => 015ce30b116ce86058fa6ab4fea4ac63
            [config_column_id] => 1
            [plan_id] => 1
            [sort_order] => 1
            [title] => 无线成都1
            [config_task_id] => 1
            [create_user_id] => 8
            [create_name] => 13281105967
            [exec_user_id] => 185
            [exec_name] => test1
            [place] => 地点
            [task_info] =>
选题摘要
            [task_data] => a:0:{}
            [ended_at] => 1530695128
            [current_step_id] => 18
            [prev_status] => 2
            [status] => 1
            [created_at] => 1528103128
            [updated_at] => 1528188754
        )
	]
)

2. Now there is a request parameter, tool, which is required. It is a tool identifier: jove: Jove micro-editing; nova: Nova fine-editing, and the validation range is ([jove, nova]).

3. Since tool does not exist in the model api\modules\v1\models\PlanTask, ad-hoc validation is required. The code is as follows:

PHP

use yii\base\DynamicModel;

class VideoEditAction extends Action
{

    const TOOL_JOVE = 'jove'; //工具：Jove微编
    const TOOL_NOVA = 'nova'; //工具：Nova精编

	// 临时验证
	$request = Yii::$app->request;
	$tool = $request->get('tool');

	$dynamicModel = new DynamicModel(compact('tool'));
	$dynamicModel->addRule('tool', 'required')
		->addRule('tool', 'in', ['range' => [self::TOOL_JOVE, self::TOOL_NOVA]])
		->validate();

	if ($dynamicModel->hasErrors()) {
		$response = Yii::$app->getResponse();
		$response->setStatusCode(422, 'Data Validation Failed.');
		foreach ($dynamicModel->getFirstErrors() as $message) {
			$firstErrors = $message;
			break;
		}
		return ['code' => 20004, 'message' => Yii::t('error', Yii::t('error', Yii::t('error', '20004'), ['firstErrors' => $firstErrors]))];
	}
}

4. Testing in Postman, when the tool parameter is not provided, it behaves as expected, as shown in Figure 1.

}

5. Testing in Postman, when the tool parameter does not equal ([jove, nova]), it behaves as expected, as shown in Figure 2.
