在 laravel5 中我收到以下消息(错误)
No query results for model [App\Products].
我有一个表“products”，其中有一列“category_id”，其中包含每个类别项目的类别 ID。我想根据 category Id
我的 Controller 是这样的
public function category()
{
$recordsByCategories=\DB::table('products')
->select('categories','category_id', \DB::raw('count(*) as totalProducts'))
->groupBy('categories')
->get();
return view('dashboard.show',compact('recordsByCategories'));
}
**//I have received error in below function**
public function searchCategoryByTag($id)
{
$category_id = Products::findOrFail($id);
$records=\DB::table('products')->Where('category_id','$category_id');
dd($records);
}
我的路线是这样的
Route::get('categorys/{id}' ,array(
'as'=>'category',
'uses'=>'GoodsController@searchCategoryByTag'));
我的观点是这样的
@foreach($recordsByCategories as $recordsByCategory)
<a href="{{URL::route('category',$recordsByCategory->category_id)}}
" id="search">{{$recordsByCategory->categories}}</a>:{{$recordsByCategory->totalProducts}}
@endforeach
