Description:

Hi,

I have a model called Deadline, which has two self-referencing relations called postponed and postpones:

class Deadline extends Model
{
    use HasFactory;

    protected $fillable = [
        'exceeds_at',
        'postponed_id',
    ];

    protected $casts = [
        'exceeds_at' => 'datetime',
    ];

    public function postponed(): BelongsTo
    {
        return $this->belongsTo(Deadline::class);
    }

    public function postpones(): HasOne
    {
        return $this->hasOne(Deadline::class, 'postponed_id');
    }
}

The nova resource for this model looks like this:

class Deadline extends Resource
{
    public static $model = \App\Models\Deadline::class;

    public function fields(NovaRequest $request)
    {
        return [
            ID::make()->sortable(),
            Date::make('exceeds_at'),
            BelongsTo::make('Postponed To', 'postponed', Deadline::class)
                ->readonly(),
            HasOne::make('Postponed From', 'postpones', Deadline::class)
                ->readonly(),
        ];
    }
}

I can view the resources without any problems:

But when I click on the edit button, I get endless loading:

The nova-api request returns HTTP 500 after either running out of memory or hitting the maximum execution time.

The Update.vue then runs into the following error:

Update.vue:165 Uncaught (in promise) TypeError: Cannot destructure property 'data' of '(intermediate value)' as it is undefined.
    at Proxy.getFields (Update.vue:165:9)

Detailed steps to reproduce the issue on a fresh Nova installation:

1. Clone https://github.com/sedlatschek/laravel-10-nova-4-issues
2. php artisan migrate:fresh --seed
3. Open any Deadline resource
4. Click on the edit button

Thanks for your help

It might be best not to include inline HasOne on create/edit for this structure. e.g:

HasOne::make('Postponed From', 'postpones', Deadline::class)->exceptOnForms(),

Thanks for your answer.

What is the desired behaviour for this case? HasOne relations that are no self-reference do not require me to add exceptOnForms() to work.
