Laravel - Automatically changing the results if null is returned

Question

Im wondering if I could get some advice.

In my blade template, i have the following;

<a href="#">{{ $gallery->creator->name }}</a>

My controller looks like this;

public function show(Gallery $gallery)
{
    return view('galleries.show', compact('gallery'));
}

The next bit is where im having some trouble, In my model i have the following relationship

public function creator()
{
    return $this->belongsTo(User::class, 'user_id');
}

Some of the galleries have a null user_id value as they are not logged in when posted.

Is there a way that I can set the $gallery->creator->name to 'Anonymous' if the user_id is null, but if there is a value, use whats already there? Any help making a mutator would be awesome

Any help would be greatly appreciated.

Cheers,

you can use a mutator for this, take a look here: laravel mutators — Naco

This is how I fixed this issue in my case.

Inside the Gallery model, where you have this relationship defined:

public function creator()
{
    return $this->belongsTo(User::class, 'user_id');
}

Add this accessor:

public function getCreatorNameAttribute()
{
    if ($this->creator) {
        return $this->creator->name;
    }
    return "Anonymous"; // any default value you want to return here.
}

And how to use it blade template:

<a href="#">{{ $gallery->creatorName }}</a>
