Question

大家好，

尝试创建客户端时，
出现错误：设置只读属性：app \ models \ form \ ClientForm :: Clientclient

如何解决此错误？

这是我的ClientClient（模型）

<key>NSExceptionMinimumTLSVersion</key>
  <string>TLSv1.0</string>
  <key>NSExceptionRequiresForwardSecrecy</key>
  <false/>
  <key>NSExceptionAllowsInsecureHTTPLoads</key>
  <true/>
  <key>NSIncludesSubdomains</key>
<true/>

这是我的ClientForm（模型）：

class ClientClient extends \yii\db\ActiveRecord
{
/**
 * {@inheritdoc}
 */
public static function tableName()
{
    return 'client_client';
}
public $clientclients;
/**
 * {@inheritdoc}
 */
public function rules()
{
    return [
        [['age', 'client_id'], 'integer'],
        [['first_name', 'patronymic', 'last_name', 'clientclients'], 'string', 'max' => 255],
    ];
}

/**
 * {@inheritdoc}
 */
public function attributeLabels()
{
    return [
        'id' => 'ID',
        'first_name' => 'First Name',
        'patronymic' => 'Patronymic',
        'last_name' => 'Last Name',
        'age' => 'Age',
        'client_id' => 'Client Id',


    ];
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getClient_id()
{
    return $this->hasOne(ClientPhone::class, ['client_id' => 'id']);
}

public function getPhone()
{
    return $this->hasOne(ClientPhone::class, ['phone_digital' => 'id']);
}
}

_form

class ClientForm extends model
{
private $_client;
private $_phone;


public function rules()
{
    return [
        [['ClientClient'], 'required'],
        [['ClientPhone'], 'safe'],
    ];
}

public function afterValidate()
{
    $error = false;
    if (!$this->ClientClient->validate()) {
         $error = true;
    }
    if (!$this->ClientPhone->validate()) {
        $error = true;
    }
    if ($error) {
        $this->addError(null); // add an empty error to prevent saving
    }
    parent::afterValidate();
}
public function save()
{
    if (!$this->validate()) {
        return false;
    }
    $transaction = Yii::$app->db->beginTransaction();
    if (!$this->ClientClient->save()) {
        $transaction->rollBack();
        return false;
    }
    $this->ClientPhone->client_id = $this->ClientClient->id;
    if (!$this->phone->save(false)) {
        $transaction->rollBack();
        return false;
    }
    $transaction->commit();
    return true;
}

public function getClientclient()
{
    return $this->_client;
}

public function setClient($client)
{
    if ($client instanceof Client) {
        $this->_client = $client;
    } else if (is_array($client)) {
        $this->_client->setAttributes($client);
    }
}

public function getphone()
{
    if ($this->_phone === null) {
        if ($this->client->isNewRecord) {
            $this->_phone = new Phone();
            $this->_phone->loadDefaultValues();
        } else {
            $this->_phone = $this->client->phone;
        }
    }
    return $this->_phone;
}



public function setPhone($phone)
{
    if (is_array($phone)) {
        $this->phone->setAttributes($phone);
    } elseif ($phone instanceof Phone) {
        $this->_phone = $phone;
    }
}

public function errorSummary($form)
{
    $errorLists = [];
    foreach ($this->getAllModels() as $id => $model) {
        $errorList = $form->errorSummary($model, [
            'header' => '<p>Please fix the following errors for <b>' . $id . '</b></p>',
        ]);
        $errorList = str_replace('<li></li>', '', $errorList); // remove the empty error
        $errorLists[] = $errorList;
    }
    return implode('', $errorLists);
}

private function getAllModels()
{
    return [
        'Client' => $this->client,
        'Phone' => $this->phone,
    ];
}

}

和控制器

<div class="clientclient-form">

<?php $form = ActiveForm::begin(); ?>

<?= $form->field($clientForm->Clientclient, 'first_name')->textInput(['maxlength' => true]) ?>

<?= $form->field($clientForm->Clientclient, 'patronymic')->textInput(['maxlength' => true]) ?>

<?= $form->field($clientForm->clientphone, 'last_name')->textInput(['maxlength' => true]) ?>

<?= $form->field($clientForm->clientphone, 'phone_digital')->widget( MaskedInput::class, ['mask' => '9999999999'])?>

<?= $form->field($clientForm->Clientclient, 'age')->textInput() ?>

<div class="form-group">
    <?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?>
</div>

<?php ActiveForm::end(); ?>

</div>

为什么Clientclient :: tags是只读的？设置模型关系的正确方法是什么？

Answer 1

我收到一个错误：设置只读属性： app \ models \ form \ ClientForm :: Clientclient

您使用的是Yii getter和setter类方法，而不是公共属性，但是在您的 ClientForm 类中仅定义了 getter 方法。您还需要添加 Setter 方法：

public function setClientclient($value)
{
    $this->_client = $value;
}

有关更多详细信息，请参见Concept Properties in official documentation。

Answer 2

最简单的方法是使用setAttributes。在$ model-> load（Yii :: $ app-> request-> post（））之前或之后调用它

$model->setAttribute('_client', $value);

Yii2设置只读属性
