Thank you so much Ahamed, I understand now. It worked!
I have also understood that this is only for the visual part because I can still access the posts url when typed manually. I will have to check out and understand how permissions work.
In the mean time I am having a really annoying problem there, no idea if you or anyone could help me please.
In another post I explained that I was following the tutorial which said to add the below code (in my posts model if I understood correctly) so I could get the creation_time and update_time field in the database filled up automatically. The problem is that I am getting an error when I add the below code in my Posts model file.
Any idea why please? Thanks!
use yii\db\Expression;
public function behaviors()
{
return [
'timestamp' => [
'class' => TimestampBehavior::className(),
'attributes' => [
ActiveRecord::EVENT_BEFORE_INSERT => 'creation_time',
ActiveRecord::EVENT_BEFORE_UPDATE => 'update_time',
],
'value' => new Expression('NOW()'),
],
];

PHP Fatal Error – yii\base\ErrorException

I went in the Expression.php file and could not find the class TimestampBehaviour, Iam using the basic version, is it why?
This is what I have inside that file:
