Framework: [BUG][5.6] undefined relationship [pivot] on model [App\Models\User] when broadcasting - sync queue

[LCD344]

• Laravel Version: 5.6.0
• PHP Version: 7.2.2
• Database Driver & Version: Mysql 5.7.2

Description:

I just updated my Laravel version to 5.6 and updated the files from github.
Then running my tests I started getting the mentioned error on all the tests that broadcast. So I'm holding up on updating my production code.

Stack trace:

Steps To Reproduce:

1. Clone laravel5.6 https://github.com/el-coop/barrioBall
2. Composer install
3. Run phpunit tests

Yes same issue here, I have removed SerializesModels since i am not queing only broadcasting and everything is back to normal.

[themsaid]

We can't find the bug looking at your entire code base, please include simple steps to replicate the issue.

[rodrigopedra]

Same issue here...

This a dd(...) from the Illuminate\Queue\SerializesAndRestoresModelIdentifiers@restoreModel traitś method:

~php
Illuminate\Contracts\Database\ModelIdentifier {#951
+class: "App\Models\User"
+id: 2
+relations: array:3 [
0 => "tenant"
1 => "roles"
2 => "roles.pivot"
]
+connection: "system"
}
~

It tries to load the nested pivot relation from the role relation, although this is an automatic relation set by Laravel when using a BelongsToMany relationship and it is not explicitly defined in theRole model

I don't know if it is better to filter the pivot related relation from the `ModelIdentifier' object when serializing, or to check if a relation is explicitly defined in the model when restoring from that object...

I'll try to figure out and work out a fix to this, but in the meantime I'm holding on upgrading my production app to 5.6

[rodrigopedra]

Steps to reproduce:

1. create a new Laravel 5.6 app
2. configure queue to use a driver that demands model serialization (e.g. Redis)
3. Load an User instance with a BelongsToMany relation loaded (e.g. $user = User::with('roles')->first())
4. Send a notification to that user
5. run php artisan queue:work
6. check the logs

I submitted PR #23081 to try to fix this issue

[JorritBerendsen]

Hi,

This is my first message on Stackoverflow, so please let me know if I miss stating any required information.

I just updated my Laravel app to version 5.6(.21) from 5.5.* and still have the same problem that the pivot relations are loaded when serializing the models for a job. So all my notification jobs break as the notifiable is a user with many settings containing a pivot relation to check what notifications to send (email, database, etc.). Seeing this card I believe this should've been fixed already?

Best, Jorrit.

[ferdinandfrank]

I still have the same issue even if the queue driver is sync. I'm on Laravel version 5.6.23. This breaks all my notifications :/

[ferdinandfrank]

Are you guys sure that this bug doesn't exist anymore in the latest Laravel version? I still have this problem and already opened a discussion at Laracasts, but nobody could find a solution: https://laracasts.com/discuss/channels/laravel/call-to-undefined-relationship-pivot-on-model-appmodelsuser-when-using-queues

[wheatevo]

I am also seeing this issue on an application I am attempting to uplift from 5.5 to 5.6.

[stemis]

I am also experiencing the same issue when upgrading from 5.5 to 5.6
This is not fixed.

As a workaround I'm calling ->fresh() before passing it to the constructor of the job.

[erikgaal]

I've opened a PR where I've identified the problem. This should resolve the issues that we're having here.
