Illuminate/Eloquent: how to use belongsTo in constructor









up vote

favorite












i would like to provide data from the "foreign key table" in the current model.



I am currently achieving this by a function (getBrand).



But now I would like to have this accessable as a property. So I added a property ($brand) and wanted to fill it by calling the function (getBrand) in the constructor of the model.



class Car extends Eloquent 
public $brand;

public function __construct()
parent::__construct();
$this->brand = getBrand();


public function getBrand()
return $this->belongsTo('AppBrand', 'FK_BrandId')->first()->Brandname;




But this creates an error during the execution of the constructor:



Trying to get property of non-object


Any ideas how to solve this? Thanks!

          You could change your getBrand function a little to the following to define the relationship between a Car and a Brand:



           public function brand() 
          return $this->belongsTo('AppBrand', 'FK_BrandId');



          The brand model can then be accessed from an instance of Car with, e.g. $car->brand. To access the brand name you can then use $car->brand->Brandname.



          If you'd like to access the brand name directly, you could define an "accessor" on the Car model like this:



          public function getBrandNameAttribute()

          return $this->brand->BrandName;



          You would then be able to access the brand name with $car->brand_name.
