試圖獲得非對象laravel的屬性5 - 我的錯誤是什麼？

Question

我的錯誤是什麼？

Employeecontroller：

public function index() 
{ 
    $employees = Employee::all(); 
    return view('employee.view_all_employee_details', compact('employees')); 
} 

員工型號功能：

protected $primaryKey = "emp_id"; 
protected $with = 'additionaldetails'; 
public function additionaldetails() 
{ 
return $this->hasOne('App/EmployeeAdditionalDetail' , 'emp_id' , 'emp_id'); 
} 

EmployeeAdditionalDetail型號：

public function employeeDetails() 
{ 
return $this->belongsTo('App\Employee' , 'emp_id' , 'emp_id'); 
} 

view_all_employee_details查看

@if(count($employees) > 0) 

@foreach($employees as $employee) 
    <tr> 
     <td> {{ $employee->first_name }} </td> 
     <td> {{ $employee->manager_id }} </td> 
     <td> 

      {{ $employee->additionaldetails->emp_id }} **Error showing here** 
     </td> 
    </tr> 
@endforeach 

@else 
    {!! "<tr><td>No Recod Found</td></tr>" !!} 

@endif 

MyError：

Trying to get property of non-object

試試這個

{{ $employee->additionaldetails->emp_id }} 

員工模型訪問basicdetails（）函數。您正嘗試使用其他詳細信息（）獲取數據。

也改變這一行

return $this->hasOne('App/EmployeeAdditionalDetail' , 'emp_id' , 'emp_id'); 

到

return $this->hasOne('App\EmployeeAdditionalDetail' , 'emp_id' , 'emp_id');
