Question

I have a table named SYSTEM_PARAMS like below
+------------+------------------+------+-----+---------------------+-----------------------------+
| Field | Type | Null | Key | Default | Extra |
+------------+------------------+------+-----+---------------------+-----------------------------+
| name | varchar(50) | NO | | NULL | |
| value | varchar(100) | YES | | NULL | |
| updated_at | timestamp | NO | | CURRENT_TIMESTAMP | on update CURRENT_TIMESTAMP |
| created_at | timestamp | NO | | 0000-00-00 00:00:00 | |
| created_by | int(11) | NO | | NULL | |
| updated_by | int(11) unsigned | YES | | 0 | |
+------------+------------------+------+-----+---------------------+-----------------------------+
where i have all names of the cron jobs i have to run and update the value against the specific job name with the current running JobId, the table does not have the primaryKey defined as you can see the schema above, so i defined the method primaryKey() inside the model like below
public function primaryKey($asArray=FALSE) {
return 'name';
}
but this gives me error saying that i can define a static method as non-static , what am i doing wrong here.
PHP Fatal error: Cannot make static method
yii\db\ActiveRecord::primaryKey() non static in class
common\models\SystemParams

Answer 1

Exactly what it says.
primaryKey is static method in ActiveRecord class.
If you want to override it you have to make it static as well.
public static function primaryKey()
{
return ['name'];
}
PS. It must return array. See this note.
