Showing Category And Subcategory In Laravel -

i using laravel 5.2. have 2 eloquent models this-

category.php-

<?php  namespace app;  use illuminate\database\eloquent\model;  class category extends model {     protected $table        =   'categories';           //table name     public $timestamps      =   false;     public $incrementing    =   false;                  //for non integer primary key     protected $primarykey   =   'name';      protected $fillable     =   [                                     'name'                                 ];      public function subcategory()     {         return $this->hasmany('app\subcategory', 'category_id', 'id');     } } 

and subcategory.php-

<?php  namespace app;  use illuminate\database\eloquent\model;  class subcategory extends model {     protected $table    =   'sub_categories';           //table name     public $timestamps  =   false;      protected $fillable     =   [                                     'category_id',                                     'name'                                 ]; } 

so, if call in controller-

return category::with('subcategory')->get(); 

i getting this-

[   {     "id": 3,     "name": "beahan-mueller",     "sub_category": [       {         "id": 27,         "category_id": 3,         "name": "carroll trail"       },       {         "id": 3,         "category_id": 3,         "name": "davis lake"       },       {         "id": 9,         "category_id": 3,         "name": "lehner ranch"       }     ]   },   {     "id": 10,     "name": "beahan, stark , mckenzi",     "sub_category": [       {         "id": 1,         "category_id": 10,         "name": "dibbert summit"       },       {         "id": 18,         "category_id": 10,         "name": "kris mount"       }     ]   } ] 

so, can tell sub-category link working, right?

but problem if want use blade show values this-

controller-

return view('public.listing.main', [                                         'current_page'          =>  'add listing',                                         'categories'            =>  category::with('subcategory')->get()                                     ]); 

view-

@foreach ($categories $category)     <li class="no-border">         <label class="pull-left">             <input type="checkbox" name="cat_{{ $category->id }}" checked>             <strong> {{ $category->name }} (21)</strong>         </label>         <ul>             @foreach($category->sub_category $sub_cat)                 <li>                     <label class="pull-left">                         <input type="checkbox" checked value="{{ $sub_cat->id }}"> {{ $sub_cat->name }} (7)                     </label>                 </li>             @endforeach         </ul>      </li> @endforeach 

i finding error it-

can please help, why finding error?

your subcategory relationship name wrong in 2nd foreach. should

@foreach($category->subcategory $sub_cat)     // code here @endforeach 

instead of sub_category.
