model->save() Not Working In Yii2

Question

Previously, I was not using $model->save() function for inserting or updating any data. I was simply using createCommand() to execute query and it was working successfully. But, my team members asked me to avoid createCommand() and use $model->save();

Now, I started cleaning my code and problem is $model->save(); not working for me. I don't know where i did mistake.

UsersController.php (Controller)

<?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");
        }

      }

    } 
    }
    .
    .
}

Everything OK in this except $model->save(); Not printing 'asd' as i echoed it.

And, if i write

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

}

It's not entering to this if condition.

And, if i write

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

It insert NULL to all columns and print 'asd'

Any help is appreciable. Please Help me.

Answer 1

if your column type in your table is "integer" and your data is "string" you may see tis error.You should check your data type and try again.

I suppose that your column type is integer, you should write the following code:

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

but your column type is string, you should write the following code:

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

Answer 2

in your model i found First name , last name , email , password is required fields and in your controller you are updating or saving only

 $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;

but first name and last name and email id are required so it will throw validation error , to check this error use

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

it will show you the error . correct that errors then model will get save. you can solve that error using Scenario or

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

I hope it will help you.

Answer 3

It could be a problem related with your validation rules.

Try, as a test, to save the model without any validation in this way:

$model->save(false);

If the model is saved you have conflict with your validation rules. Try selectively removing your validation rule(s) to find the validation conflict.

If you have redefined the value present in active record you don't assign the value to the var for db but for this new var and then are not save.

Try removing the duplicated var.. (only the vars non mapped to db should be declared here.)

Answer 4

As @scaisEdge suggest, try removing all table related field in your Users class

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 5

Try this:

$model->save(false);

and if thats working, check your model rules() and your form rules() if its having the same rules. usually the cause is the required fields in your table.

Answer 6

And there maybe another reason of not saving model - you have property of your Users class and before saving from form its reset to NULL.

So, if you set $model->saveAttributes('favorite_book'=>$model->favorite_book), but at that time you declared in class Users public $favorite_book - you will get this field empty in DB.
