将外键值保存在相关表中-Laravel资源控制

时间:2018-10-30 14:03:19

标签: laravel crud laravel-resource

我有2张桌子:制造商和品牌。

制造商: 字段:ID和制造商

品牌: 字段:具有“ manufacturer_id”字段的许多其他字段,这些字段索引“ Manufacturers”表的“ id”。

我有一个选择框,该选择框应该从制造商表中加载制造商字段。 当存储在db中时,我需要在Brands表中存储制造商的'id'。

这是一对一的关系,但我不知道如何使用Laravel资源控制器模型来实现。.CRUD

我也设置了外键

这是BrandsContoller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Brands;
use App\Manufacturer;
use App\Contents;
use App\Usage;
use App\Type;
use App\SideEffect;

class BrandsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $brand_names = Brands::latest()->paginate(5);
        return view('brands.index', compact('brand_names'))->with('i',(request()->input('page',1)-1)*5);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {

        // $manufacturerList = Manufacturer::find(2);
        //$brand = Manufacturer::find(3)->brand;
        return view('brands.create', compact('brand'));
    }

    public function test($id){

        $manufacturerss = Manufacturer::find($id);
        return view('test', compact('manufacturer'));
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        // request()->validate([
        //     'brand_name' => 'required',

        // ]);
        // $manufacturer->brands()->save($manufacturer);
        // $manufacturer->manufacturer()->associate($manufacturer)->save();

        Brands::create($request->all());
        // $brand = new Brands;
        // $brand -> manufacturer_id = $data-> manufacturer_id;
        // $brand -> save();
        // @foreach($manufacturerList as $item)
        // {

        //     $brand->manufacturer()->create(['manufacturer_id' => $item]);

        // }
        // @endforeach

        return redirect()->route('brands.index')->with('success', 'Brand created succesfully');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $brand_name = Brands::find($id);
        return view('brands.show',compact('brand_name'));
    }

    /**
     * Show the form for editing the specified resource.

    public function edit($id)
    {
        $brand_name = Brands::find($id);
        return view('brands.edit', compact('brand_name'));
    }

    /**

     */
    public function update(Request $request, $id)
    {
        request()->validate([
            'brand_name' => 'required',
            'short_description' => 'required',
            'manufacturers_id' => 'required',

            'storage' => 'required',
            'discalimer' => 'required',
        ]);
        Brands::find($id)->update($request->all());
        return redirect()->route('brands.index')->with('success', 'Brand updated succesfully');
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        Brands::find($id)->delete();
        return redirect()->route('brands.index')->with('success', 'Brand sucessfully deleted');
    }
}

这是品牌模型:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Brands extends Model
{
    protected $table = 'brands';
    protected $fillable = ['brand_name','short_description','content_id','usage_id','type_id','photo','side_effect_id','common_use','dosage_directions','precautions','contradictions','possible_side_effects','drug_interactions','missed_dose','overdose','storage','discalimer'];

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

这是制造商型号:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Manufacturer extends Model
{
    protected $table = 'manufacturers';
    protected $fillable = ['manufacturer'];

    public function brand()
    {
    return $this->hasOne('App\Brands','manufacturer_id');
    }
}

这是我的前端,具有选择框:

<strong>MANUFACTURER : </strong>

      <br>
      <select id="manufacturers" name="manufacturers" class="form-control item_view" placeholder="Please choose" onchange="">
      <option>Select Manufacturer</option>
      <option value="0">Add New</option>


      <option value="" >test</option>



      </select>

我在修补程序中得到了正确的值,但是我不知道如何保存在数据库中。

非常感谢任何帮助。...

1 个答案:

答案 0 :(得分:0)

使用Model :: create()和Model :: update()方法时,将使用模型上的fillable或guarded属性过滤数据。

由于您的品牌模型在可填充内容中没有'manufacturers_id',因此该字段不会保存在数据库中。

此外,您需要将选择的输入命名为“ manufacturers_id”,以将正确的属性发送到后端。

提示:

  • 我建议在模型,数据库和关系中使用Eloquent Model Conventions。例如:使用“品牌”模型,而不是“品牌”模型,并使用Manufacturer_id,而不是Manufacturer_id。使用这些约定,Laravel Eloquent ORM可以轻松管理您的查询,并且代码可以更加清晰简洁。
