Coding Practices and Examples for Samarth

Identity Management​

Use Yii::$app->user->identity->assigned_to for:

  • Reason: "AssignedTo" field in User table consists of EmployeeId in case of Employee type of Account and "OrganigramID" in case of Administrative type of Account.
  • Use SecurityHelper::validateData($id) for decoding user ids

Identity control for GridView​

Use $dataProvider->query->andFilterWhere(['exam_session_id' => $session]) for:

  • Reason: For filter in Data Grid View use below syntax:

    $user_id = SecurityHelper::validateData($id);
    $searchModel = new PublicProfileSearch();
          $searchModel->ems_profile_id = $user_id;
          $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
    $dataProvider->query->andFilterWhere(['ems_profile_id' => $user_id]);

Use following code snippet in model for auto filling created at/by and updated at/by fields​

As a standard practice place this before the attribute label block

BlameableBehavior automatically fills the specified attributes with the current user ID.

public function behaviors()
{
    return [
        [
        'class' => BlameableBehavior::className(),
        'createdByAttribute' => 'created_by',
        'updatedByAttribute' => 'updated_by',
        ],
        'timestamp' => [
            'class' => 'yii\behaviors\TimestampBehavior',
            'attributes' => [
                ActiveRecord::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
                ActiveRecord::EVENT_BEFORE_UPDATE => ['updated_at'],
            ],
        ],
    ];
}
