Laravel关系错误 - 试图获取非对象的属性

I am trying to get the id of the relations I have setup.

Plate model

public function plateContainer()
{
    return $this->belongsTo('App\Models\PlateContainer');
}

PlateContainer Model

public function plate()
{
    return $this->hasMany('App\Models\Plate');
}

public function equipmentStatusCode()
{
    return $this->hasOne('App\Models\EquipmentStatusCode');
}

EquipmentStatusCode Model

public function plateContainer()
{
    return $this->belongsTo('App\Models\PlateContainer');
}

When I try.

    $p  = Plate::findOrFail(4);
    $p->plateContainer->equipmentStatusCode;

  return $p;

I get Trying to get property of non-object. What I am doing wrong?

Try this:

I just tried to create a similar situation. I modified the code likewise:

$p  = Plate::findOrFail(4);

$p->equipmentStatusCode->plateContainer;
return $p;

I was able to fetch the result array.

plateContainer and equipmentStatusCode are a functions. Use rounded brackets.

Add the following relation to the Plate model:

public function equipmentStatusCode()
{
    return $this->hasManyThrough('App\Models\EquipmentStatusCode', 'App\Models\PlateContainer');
}

And try:

$p  = Plate::findOrFail(4);
$p->equipmentStatusCode();

return $p;
