use \Staudenmeir\EloquentJsonRelations\HasJsonRelationships;
public function category()
        {
            return $this->belongsToJson(ProductCategory::class, 'product_category_id');
        }

but did'nt get the expected result

CodePudding user response：

Define the field type in model and try it. Also please make sure the array should not have the key.

protected $casts = [
       'product_category_id' => 'json',
    ];
