Laravel 5.4中的ORM无法正常工作

Question

I have 2 tables "Items" and "brands". items contains product details such as item_id, name and brand_id while brands contains brandId and brand_name. I want to fetch Item data in which I can join brands and items.

This is my controller.

public function filters($id){
    $items = Items::brands();       
    return $items;
}

This is my model.

public static function brands(){
    return $this->hasOne('App\Brands');
}

I got the following while running on my browser. Using $this when not in object context

Answer 1

Try like this :

Model File :

public function brands(){
    return $this->hasOne('App\Brands');
}

And controller like this :

public function filters($id){
    $items = Items::select("*")->with('brands')->get()->toArray();       
    return $items;
}

Answer 2

Remove the static keyword

public function brand(){
    return $this->hasOne('App\Brands','brand_id');
}

in your Brands you need

public function item(){
    return $this->belongsTo('App\Items','brandId','brand_id');
}

and your controller:

public function filters($id){
    $items = Items::all()->with('brands')->get();       
    return $items;
}
