Question

我现在正在开展一个名为Hospital＆amp; amp;的项目。医生信息。我在这里有不同的孟加拉国分部和在每个部门中，根据其所有权，存在某些类型的医院。但是当我得到不同医院的价值时，它显示出一些错误。它没有找到具体的身份证明。我之前已经问了问题。但它没有解决我的问题。所以我再问这个问题。我的路线文件

Route::get('/district/{id}', array('as' =>'district' ,'uses' => 'UserController@district'));

Route::get('/district/hospital/{id}', array('as' =>'hospital' ,'uses' => 'UserController@hospital'));

Route::get('/district/hospital/hospital_info/{id}', array('as' =>'hospital_info' ,'uses' => 'UserController@hospital_info'));

模范医院

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Hospital extends Model
{

    protected $fillable = [
        'name',
        'division_id',
        'district_id',
        'category_id',
    ];

    public function district()
    {

        return $this->belongsto('App\District');
    }
}

区域模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class District extends Model
{
    protected $fillable=[
        'name',
        'division_id',
    ];



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

    public function category()
    {
        return $this->hasmany('App\Categories');
    }
    public function dcategory()
    {
        return $this->hasmany('App\Dcategories');
    }

    public function hospital()
    {
        return $this->hasmany('App\Hospital');
    }
}

分部模型是

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Input;

class Division extends Model
{
    protected $fillable = ['name'];

    public function districts()
    {

        // $divisions = Division::all(); 
     //    $division_id = Input::get('id');
        return $this->hasMany('App\District','division_id');
    }
}

错误是

我几天前问了这个问题，但没有找到答案。 Plz帮助我。

Answer 1

您的主要问题是您是否正在尝试从ID获取医院，但您尚未在医院模型中定义任何ID，因此首先应将id列添加到您的医院模型中。

其次从这个

改变你的功能

public function hospital_info($id)
{
    $divisions = Division::all();
     $division=Division::find($id); 

     $district=District::find($id); 

     $categories=Category::all();
     $cats=Category::find($id); 
     $hospitals=Hospital::find($id); 

    // $districts=District::where('division_id', '=', $divisions->id)->get();

    // if (!$district)
    // {
    //     throw new NotFoundHttpException;
    // }
    return view('users.hospital_info')
                ->with('divisions',  $divisions)
                ->with('division', $division)
                ->with('district', $district)
                ->with('categories',$categories)
                ->with('cats',$cats)
                ->with('hospitals',$hospitals);
}

到此

public function hospital_info($id)
{
    $hospital=Hospital::find($id);
    $divisions = Division::all();
    $categories=Category::all();


    // $districts=District::where('division_id', '=', $divisions->id)->get();

    // if (!$district)
    // {
    //     throw new NotFoundHttpException;
    // }


    return view('users.hospital_info') , compact('divisions','categories', 'hospital');
}

那么你可以得到这样的信息

                            <div class="col-xs-12 col-sm-6 blog-content">
                                <h2>{{ $hospital->name }}</h2>
                            </div>

             @foreach($divisions as $itemDivision)
                        @foreach($categories as $itemCategory)
                            <div class="col-xs-12 col-sm-6 blog-content">
                                <h2>{{ $itemDivision->name }}</h2>
                            </div>
                        @endforeach
                    @endforeach

例如，获取有关学区的所有信息：

您应该将（id）列添加到所有模型中，以便以后使用它们你的函数内部执行此操作：

public function district($id)
{
    $district=District::findorfail($id); 
    $hospitals = DB::table('hospitals')
    ->leftjoin('districts' ,'hospitals.district_id' , '=', 'districts.id')
    ->where('district.id','=',$id)
    ->select('hospitals.*')
    ->get();



    return view('users.district'),compact('district','hospitals') ;
}

当然，医院是一系列对象，您应该使用循环来获取每家医院的信息
