Question

以前，我没有使用$model->save()函数来插入或更新任何数据。我只是使用createCommand()来执行查询，它正在成功运行。但是，我的团队成员要求我避免createCommand()并使用$model->save();

现在，我开始清理我的代码，问题$model->save();对我不起作用。我不知道我错在哪里。

UsersController.php （控制器）

<?php
namespace app\modules\users\controllers;
use Yii;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\swiftmailer\Mailer;
use yii\filters\AccessControl;
use yii\web\Response;
use yii\widgets\ActiveForm;
use app\modules\users\models\Users;
use app\controllers\CommonController;

class UsersController extends CommonController 
{
    .
    .

    public function actionRegister() {
    $model = new Users();

        // For Ajax Email Exist Validation
   if(Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())){
     Yii::$app->response->format = Response::FORMAT_JSON;
     return ActiveForm::validate($model);
   } 

   else if ($model->load(Yii::$app->request->post())) {
      $post = Yii::$app->request->post('Users');
      $CheckExistingUser = $model->findOne(['email' => $post['email']]);

      // Ok. Email Doesn't Exist
      if(!$CheckExistingUser) {

        $auth_key = $model->getConfirmationLink();
        $password = md5($post['password']);
        $registration_ip = Yii::$app->getRequest()->getUserIP();
        $created_at = date('Y-m-d h:i:s');

        $model->auth_key = $auth_key;
        $model->password = $password;
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

        if($model->save()) {
          print_r("asd");
        }

      }

    } 
    }
    .
    .
}

除了$model->save();之外，其他所有内容都没问题。当我回复它时，不打印'asd'。

而且，如果我写

else if ($model->load(Yii::$app->request->post() && $model->validate()) {

}

它未进入此if状态。

而且，如果我写

if($model->save(false)) {
    print_r("asd");
}

它向所有列插入NULL并打印'asd'

任何帮助都是值得的。请帮助我。

Answer 1

这可能是与验证规则相关的问题。

尝试以此方式保存模型而不进行任何验证：

$model->save(false);

如果模型已保存，则表明您的验证规则存在冲突。尝试有选择地删除验证规则以找到验证冲突。

如果您已重新定义活动记录中存在的值，则不要将该值分配给db的var，但是对于此新var，则不保存。

尝试删除重复的var ..（只应在此处声明未映射到db的vars。）

Answer 2

我猜$model->load()会返回false，请致电$model->errors查看模特的错误。

$model->load();
$model->validate();
var_dump($model->errors);

Answer 3

正如@scaisEdge建议的那样，尝试删除用户类中的所有与表相关的字段

class Users extends ActiveRecord implements IdentityInterface 
{
  /* removed because this properties is related in a table's field 
  public $first_name;
  public $last_name;
  public $email;
  public $password;
  public $user_type;
  public $company_name;
  public $status;
  public $auth_key;
  public $confirmed_at;
  public $registration_ip;
  public $verify_code;
  public $created_at;
  public $updated_at;
  public $user_type;
  public $company_name;
  public $status;
  public $auth_key;
  public $confirmed_at;
  public $registration_ip;
  public $verify_code;
  public $created_at;
  public $updated_at;
  */

  // this is properties that not related to users table
  public $rememberMe;
  public $confirm_password;
  public $_user = false;

  public static function tableName() {
    return 'users';
  }

 /* ........... */

}

Answer 4

你正在为所有员工做正确的事。我想你必须添加一行来确认密码验证

if(!$CheckExistingUser) {    
$auth_key = $model->getConfirmationLink();
        $password = md5($post['password']);
        $registration_ip = Yii::$app->getRequest()->getUserIP();
        $created_at = date('Y-m-d h:i:s');

        $model->auth_key = $auth_key;
        $model->password = $password;
        $model->confirm_password= md5($post["confirm_password"]);  /// add  this line
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

并且在此条件之后还检查模型属性和错误，如下所示：

if($model->save()) {
          print_r("asd");
        }else{
var_dump($model);exit;}

Answer 5

另一个解决方案提到$model->save(false);。这只是一个临时的解决方法，您仍然应该找到保存功能无法正常工作的实际原因。

以下是帮助诊断实际问题的其他步骤：

检查_form输入字段是否具有正确的名称和
检查是否添加了任何下拉功能，然后检查它是否正常工作

Answer 6

检查模型保存错误，如下所示：

if ($model->save()) {

} else {
  echo "MODEL NOT SAVED";
  print_r($model->getAttributes());
  print_r($model->getErrors());
  exit;
}

Answer 7

试试这个：

$model->save(false);

如果有效，请检查您的模型规则（）和表单规则（）（如果有）有相同的规则。通常原因是表格中的必填字段。

Answer 8

如果您的表中的列类型是＆＃34;整数＆＃34;你的数据是＆＃34;字符串＆＃34;您可能会看到错误。您应该检查您的数据类型，然后重试。

我认为您的列类型是整数，您应该编写以下代码：

$model->created_at=time();//1499722038
$model->save();

但是您的列类型是字符串，您应该编写以下代码：

$model->created_at=date('d/m/Y');//11/07/2017
$model->save();

Answer 9

还有另一个原因就是没有保存模型 - 你拥有了你的Users类的属性，并且从表单保存之前它的重置为NULL。

所以，如果您设置$ model-＆gt; saveAttributes（'favorite_book'=＆gt; $ model-＆gt; favorite_book），但是当时您在类Users public $ favorite_book中声明 - 您将在DB中将此字段设为空

Answer 10

在您的模型中，我发现名字，姓氏，电子邮件，密码是必填字段，在控制器中您只是更新或保存

 $model->auth_key = $auth_key;
        $model->password = $password;
        $model->confirm_password= md5($post["confirm_password"]);  /// add  this line
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

但是名字和姓氏和电子邮件ID都是必需的，所以它会抛出验证错误，检查此错误使用

$model->load();
$model->validate();
var_dump($model->errors);

它会显示错误。纠正错误然后模型将得到保存。您可以使用Scenario或

解决该错误

$model->saveAttributes('favorite_book'=>$model->favorite_book,'favorite_movie'=>$model->favorite_movie);

我希望它会对你有所帮助。

model-＆gt; save（）在Yii2中不起作用
