💡 Hint

Common Mistakes

Using 'listen' instead of 'observe' causes errors because 'listen' is for events, not observers.

Using 'watch' or 'handle' are not valid methods on the model.

In Laravel, you register an observer on a model using the observe method.

💡 Hint

Common Mistakes

Using 'creating' triggers before save, not after.

Using 'updated' triggers only on update, not on create.

The saved method in an observer is called after a model is saved (created or updated).

💡 Hint

Common Mistakes

Using 'delete' causes method not found errors.

Using 'deleted' triggers after deletion, not before.

The deleting method is called before a model is deleted. Using delete or destroy is incorrect.

4fill in blank

Fill both blanks to create a model observer method that runs after a model is updated.

Laravel

public function [1](User $user) {
    // This runs [2] the model update
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'updating' runs before update, not after.

Writing 'before' in the comment is incorrect for this method.

The updated method runs after the model update is complete.

5fill in blank

hard

Fill all three blanks to define an observer method that runs before a model is created and logs the model's name.

Laravel

public function [1](User $user) {
    Log::info('Creating user: ' . $user->[2]);
    // Additional code [3]
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'created' runs after creation, not before.

Accessing a wrong property instead of 'name'.

The creating method runs before the model is created. Accessing $user->name gets the user's name. The comment placeholder is just a marker.
