Question

创建主题时我无法获得category_id。这是我的代码和mysql。我想我在论坛控制器上存储方法有问题。

主题创建页面

@extends('app')

@section('content')
    <h1>トピック</h1>
    <hr>
    {!! Form::open(['url' => 'forums']) !!}

        <div class="form-group">
            {!! Form::label('title', 'タイトル:') !!}
            {!! Form::text('title', null, ['class' => 'form-control']) !!}
        </div>

        <div class="form-group">
            {!! Form::label('body', '本文:') !!}
            {!! Form::textarea('body', null, ['class' => 'form-control']) !!}
        </div>

        <div class="form-group">
            {!! Form::label('category', 'カテゴリー:') !!}
            {!! Form::select('category', $categories,null, ['class' => 'form-control']) !!}
        </div>

        <div class="form-group">
            {!! Form::submit('送信',['class' => 'btn btn-primary form-control']) !!}
        </div>

    {!! Form::close() !!}

@stop

论坛控制器

<?php

namespace App\Http\Controllers;

use App\Category;
use App\User;
use App\Http\Controllers\Controller;
use App\Http\Requests;
use App\Topic;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class ForumsController extends Controller
{
    public function index()
    {
        $categories = Category::all();
        $topics = Topic::latest()->get();
       return view('forums.index',compact('categories','topics'));
    }

    public function create()
    {
      $categories = Category::lists('title', 'id');
       return view('forums.create', compact('categories'));
    }

    public function store(Request $request)
    {
      Auth::user()->topics()->save(new Topic($request->all()));



       // flash()->success('投稿しました','success');

       // return redirect('forums');
    }
}

类别模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    protected $fillable = [
        'title'
        ];

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

主题模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class topic extends Model
{
    protected $fillable = [
        'title',
        'body'
        ];

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

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

Answer 1

将category_id添加到主题的模型可填充数组中，如下所示

 protected $fillable = [
     'title',
     'body',
     'category_id'
    ];

我无法将category_id存储在桌面上
