Laravel Nova relations problem

Hi! I'm Laravel Nova newbie and got a problem I can not idea how to solve:

I have resource eg. Humans. During creating new Human I have to add father, mother and grandfather. All data are stored in the same table - humans. Human belongs to: father, mother, grandfather. Grandfathers, mothers and fathers have many humans.

In resourse file I have:

BelongsTo::make('Human', 'mother'), BelongsTo::make('Human', 'father'), BelongsTo::make('Human', 'grandfather'),

, and in model file I have:

public function mother() { return $this->belongsTo(Human::class); }

public function father() { return $this->belongsTo(Human::class); }

public function grandfather() { return $this->belongsTo(Human::class); }

It works, but I don't know how to make own names in resource file for mother, father and grandfather and also I don't know how to make relation HasMany in model to show humans belongs to eg. mother

Thank you for any advice.

Nova guesses the name of the resource based on the first parameter passed to BelongsTo::make(). You should be explicit about the associated resource if you want to alter the labels:

BelongsTo::make('Mother', 'mother', Human::class), // note: Human = resource class
BelongsTo::make('Father', 'father', Human::class),
BelongsTo::make('Grandfather', 'grandfather', Human::class),

Thank you. It works. There is only one problem: On Index page and Detail page I can see: Father, Mother, Grandfather labels. But on Edit page I see Horse label next to select field.

One question more: how to list humans belonging to eg. grandfather?

In model file I did:

public function humans() { return $this->hasMany(Human::class); }

, and in resource file I have:

HasMany::make('humans', Human::class),

, but it does not work.
