Yii - 从模型中获取属性

Question

I have a model that has data set dynamically using the following:

$array = array('user_id' => 12345);
$model->setAttributes($array);

But when I run the following on the next line down it returns null?

echo $model->user_id; // i would expect to see 12345

Can anyone explain why this is null?

Answer 1

setAttributes will only work on attributes that have rules set on it. If there is no rule set for the attribute user_id, then you need to put it under safe rule. This is related to Massive Assignment.
