yii2 gii crud db关系(一对多)

gii generated models successfully (with relations) :

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

but when i generated crud, in client filed just input text field. Help me please, where is problem?

gii生成的模型成功(带关系):

  /  ** 
 * @return \ yii \ db \ ActiveQuery 
 * / 
共享函数getClient()
 {
返回$ this-> hasOne(Client :: className(),['id'=>  'client_id']); 
} 
   
 
 

但是当我生成crud时,在客户端文件中只输入文本字段。 请帮助我,问题出在哪里?

    That's correct. In your _form.php file you have to define a dropdown box if the user should choose a client:

    <?= $form->field($model, 'client')->dropDownList($clients) ?>
    

    and in controller actions create/update you have to provide the $clients:

    return $this->render('create', [  // or: return $this->render('update', [
        'model'    => $model,
        'clients' => ArrayHelper::map(Client::find()->all(), 'id', 'name'),
    ]);
    

    Don't forget to pass them in the view files for create.php and update.php to the _form.php file:

    <?= $this->render('_form', [
        'model' => $model,
        'clients' => $clients, // <-- added
    ]) ?>
    

    In other views where you just want to show client you may use this:

    echo $model->client->name; //or something different
