Question

我正在构建一个员工管理系统，员工部分工作正常，但当我尝试为员工创建家庭成员时，我遇到了问题。我希望我能以这种方式为员工创建一个家庭成员本地主机/ mysite的/雇员/ 5 /家庭/创建

这是我的档案 P.S - 我省略了一些我认为无关紧要的代码。例如，我保存了超过30个员工字段。对于这个问题，我只显示了FirstName

routes.php文件

Route::resource('employees', 'EmployeesController');
Route::resource('employees.families', 'FamiliesController');

EmployeesController.php

<?php

namespace App\Http\Controllers;

use Carbon\Carbon;
use App\Employee;
use Illuminate\Http\Request;
use DB;
use App\Http\Controllers\Controller;


class EmployeesController extends Controller
{

    public function index()
    {              
        //Stuff that works well on employees/index
    }

    public function create()
    {
        //Stuff that works well on employees/create
    }

    public function store(Request $request)
    {
        //Stuff that works well     
    }


    public function show(Employee $employee)
    {
        $employee=Employee::find($EmployeeID);
        return view('employees.show', compact('employee'));
    }


    public function edit($EmployeeID)
    {
        $employee=Employee::find($EmployeeID);          
        return view('employees.edit',compact('employee'));
    }


    public function update(Request $request, $EmployeeID)
    {
         //Stuff that works well on employees/edit
    }

}

Employee.php（模型）

<?php

namespace App;

use Illuminate\Database\Eloquent\SoftDeletes;

use Illuminate\Database\Eloquent\Model;

class Employee extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];

    protected $primaryKey = 'EmployeeID';

    protected $fillable=[
        'Name'
    ];

    public function families()
    {
        return $this->hasMany('App\Family');
    }
}

FamilyController.php（目前我只发布索引并创建方法）

<?php

namespace App\Http\Controllers;

use App\Employee;
use App\Family;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class FamiliesController extends Controller
{
    public function index(Employee $employee)
    {
        return view('families.index', compact('employee'));
    }

    public function create(Employee $employee)
    {
        return view('families.create', compact('employee'));
    }

}

Family.php（模特）

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Family extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];

      protected $primaryKey = 'FamilyID';

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

当我导航到http://localhost/mysite/public/employees/1/families/create时，我可以看到创建表单，但它没有获得员工数据。我在该页面上做了一个$ employee的vardump，我希望看到EmployeeID = 1的数据（你可以从网址上看到），但它是空白的。有趣的是，它不会抛出错误，它接收从控制器传递的$ employee数据，但它是一个空白数据。

那可能是什么问题？

Answer 1

familiescontroller.php 上的create方法未获取我们正在使用的员工。以下是创建方法应该如何在

上

 public function create($EmployeeID)
    {
        $employee = Employee::findOrFail($EmployeeID);
        return view('families.create')->with('employee', $employee);
    }

嵌套视图无法从Laravel 5.1中的父控制器获取数据
