Show the whole error, it sounds like you're probably trying to read a value on a relationship without loading said relationship.

mint light Oct 13, 2022, 7:24 PM

#

But when I delete the last instance it works very well

#

The controller can read the relationship

so I don't understand, I check some forum and it said that the php version is the problem

#

The error isn't saying service_status_id is null, it is saying whatever you're trying to check that variable on is null.

#

Show the whole error.

oooooh ok

#

So it sounds like serviceTracking relationship isn't loaded. Check out https://laravel.com/docs/9.x/eloquent-relationships#eager-loading

mint light Oct 13, 2022, 7:28 PM

#

But why is the relationship is load before ?

royal trout Oct 13, 2022, 7:29 PM

#

I don't understand your question, sorry.

mint light Oct 13, 2022, 7:29 PM

#

I already have data in the database Service and ServiceTracking, and the relation is load in the view

#

but now when I create a new Service I have this problem

#

I already create 4 Services and never have this problem

royal trout Oct 13, 2022, 7:31 PM

#

Did those services all have ServiceTracking relationships? Maybe the problem is that the service you're adding is missing a serviceTracking relationship and you're not checking if the relationship exists before trying to access a field on it.

mint light Oct 13, 2022, 7:32 PM

#

Yes they all have a ServiceTracking

royal trout Oct 13, 2022, 7:32 PM

#

Adjust your code to instead be

  @foreach ($services as $service_wait)
    @if ($service_wait->serviceTracking && $service_wait->serviceTracking->service_status_id == 1)

mint light Oct 13, 2022, 7:34 PM

#

But they have a ServiceTracking

#

it's required when create a Servic

#

#

ServiceTracking Model have this

royal trout Oct 13, 2022, 7:35 PM

#

That isn't serviceTracking .. that is serviceStatus

mint light Oct 13, 2022, 7:36 PM

#

In the ServiceTracking Model I load service status

royal trout Oct 13, 2022, 7:36 PM

#

The problem isn't your serviceTracking -> serviceStatus relationship. It is service -> serviceTracking relationship either not existing or not being loaded.

mint light Oct 13, 2022, 7:36 PM

#

oh okay

#

public function serviceTracking()

{

    return $this->hasOne(ServiceTracking::class);

}

#

I have this

royal trout Oct 13, 2022, 7:38 PM

#

That defines the relationship, but that doesn't mean it is loaded when you grab the service.

#

Take a look at the eagerloading documentation I posted.

mint light Oct 13, 2022, 7:39 PM

#

It is load because old Service work well

#

I can see it at the view so the relation is load

#

it's just now when I create a new one

royal trout Oct 13, 2022, 7:40 PM

#

Are you sure you're creating the relationship when you create a new one?

mint light Oct 13, 2022, 7:40 PM

#

That's why I don't understand the problem

#

Yes

royal trout Oct 13, 2022, 7:40 PM

#

Show

mint light Oct 13, 2022, 7:41 PM

#

#

All Services have ServiceTracking

#

So when I delete the last one all works very well

#

I delete the last Service, the last ServiceTracking etc ..

royal trout Oct 13, 2022, 7:43 PM

#

Show the services too.

mint light Oct 13, 2022, 7:43 PM

#

And I didn't touch the code before it

#

#

it's like ths

royal trout Oct 13, 2022, 7:45 PM

#

Show your new one that is breaking it.

mint light Oct 13, 2022, 7:45 PM

#

royal trout Oct 13, 2022, 7:46 PM

#

Can you show your controller code?

mint light Oct 13, 2022, 7:47 PM

#

yes

#

mint light Oct 13, 2022, 7:50 PM

#

royal trout Can you show your controller code?

I think the problem is from the server maybe I'm not sure

royal trout Oct 13, 2022, 7:52 PM

#

 @if(!$service_wait->serviceTracking) 
    dd($service_wait)
  @endif

mint light Oct 13, 2022, 7:53 PM

#

Thanks you very much for the help ! very very much I'm very in panic

royal trout Oct 13, 2022, 7:53 PM

#

Add that inside your foreach, show me which service is failing.

mint light Oct 13, 2022, 7:53 PM

#

okay

#

Undefined property: Illuminate\Pagination\Paginator::$serviceTracking

#

I have this error

royal trout Oct 13, 2022, 7:59 PM

#

Eh? Show me the code with my update

mint light Oct 13, 2022, 8:00 PM

#

yes I do it

royal trout Oct 13, 2022, 8:01 PM

#

Actually might be better to just dump the contents of $services in your controller and show me the output.

mint light Oct 13, 2022, 8:35 PM

#

Okay !
