Laravel 5未定義的屬性：Illuminate \\ Database \\ Eloquent \\ Collection :: $ basicdetails

Question

我怎么了

我的控制器：

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

我的員工模型功能：

public function basicdetails()
{
    return $this->hasOne('App/EmployeeAdditionalDetail' , 'emp_id' , 'emp_id');
}

我的EmployeeAdditionalDetail模型：

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

我的觀點

@if(count($employees) > 0)

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

              {{ $employee->basicdetails->personal_email }} </p> **Error showing here**
            </td>
        </tr>
    @endforeach

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

@endif

我的錯誤：

C：\\ xampp \\ htdocs \\ socialhub \\ app \\ Http \\ Controllers \\ EmployeeController.php第22行中的ErrorException：未定義的屬性：Illuminate \\ Database \\ Eloquent \\ Collection :: $ basicdetails

Answer 1

我懷疑問題在於$ this-> hasOne（..）的第三個參數，它應該是'local_key'，通常是'id'。

嘗試刪除第三個參數，或輸入正確的local_key：

public function basicdetails()
{
    return $this->hasOne('App/EmployeeAdditionalDetail' , 'emp_id');
}
