php - I am facing issue while updating the data into table in Yii2

one text

Solution:

The link() method of yii\db\ActiveRecord is expecting the relation to use primary key. By default the frameworks finds the primary key from db schema but your tables doesn't have any primary keys.

You can try to override method in your model to make framework use columns with unique index as primary key instead of looking for them in db schema.

public static function primaryKey()
{
    return ['id', 'consumer_id'];
}
