Laravel 9 – Attempt to read property "nom_prenoms" on null

I have two models as follows.

Tier Model:

public function contact(){
    return $this->belongsTo(ContactAdresse::class,"contact_adresse_id");
}

ContactAdresse Model:

public function tiers(){
    return $this->hasMany(Tier::class);
}

Now I’m trying to retrieve the Tier associated with the Contact using this code:

{{ $ContactAdresse->tier->nom_prenoms}}

I have the following error.

Attempt to read property "nom_prenoms" on null

Does anyone have an idea, please?

>Solution :

If you want to access the nom_prenoms property of each Tier associated with a ContactAdresse, you can loop through the tiers collection like this.

@foreach($ContactAdresse->tiers as $tier)
    {{ $tier->nom_prenoms }}
@endforeach
