Laravel - SQLSTATE[23000]：违反完整性约束：1048 列“body”不能为空 |控制器中的 CRUD 更新

Question

管理我的 CRUD 的资源控制器卡在“更新”部分，我不明白为什么。我尝试更改为 body->nullable();但这没有用。下面是我的前端设计的图片：

PostsController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
use App\Models\Post;
// use DB;

class PostsController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth', ['except' => ['index', 'show']]);
    }

    /**
     * Display a listing of the resource.
     */
    public function index()
    {      
        // $posts = Post::all();
        // return $post = Post::where('title', 'Post Two')->get();
        // $posts = DB::select('SELECT * FROM posts');
        // $posts =  Post::orderBy('created_at', 'desc')->take(1)->get();
        // $posts =  Post::orderBy('created_at', 'desc')->get();
        $posts =  Post::orderBy('created_at', 'desc')->paginate(10);

        return view('posts/index')->with('posts', $posts);
    }

    /**
     * Show the form for creating a new resource.
     */
    public function create()
    {
        return view('posts/create');
    }

    /**
     * Store a newly created resource in storage.
     */
    public function store(Request $request)
    {
        // Validating Create Post form requirements
        $this->validate($request, [
            'title' => 'required',
            'description' => 'required',
            'body' => 'required',
            'cover_image' => 'image|max:1999'
        ]);

        // Handle File Upload
        if($request->hasFile('cover_image')) {
            // Get filename with the extension
            $filenameWithExt = $request->file('cover_image')->getClientOriginalName();

            // Get just filename
            $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);

            //get just ext
            $extension = $request->file('cover_image')->getClientOriginalExtension();

            // Filename to store
            $fileNameToStore = $filename.'_'.time().'.'.$extension;

            // Upload the Image
            $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);
        } else {
            $fileNameToStore = 'noimage.jpg';
        }

        // Creating a new Post
        $post = new Post;
        $post->title = $request->input('title');
        $post->description = $request->input('description');
        $post->body = $request->input('body');
        $post->user_id = auth()->id();

        if ($request->hasFile('cover_image')) {
            $post->cover_image = $fileNameToStore;
        }

        $post->save();

        return redirect('/posts')->with('success', 'Posts Created');
    }

    /**
     * Display the specified resource.
     */
    public function show(string $id)
    {
        $post =  Post::find($id);

        return view('posts/show')->with('post', $post);
    }

    /**
     * Show the form for editing the specified resource.
     */
    public function edit(string $id)
    {
        $post =  Post::find($id);

        // Check for correct user
        if (auth()->user()->id !== $post->user_id) {
            return redirect('/posts')->with('error', 'Unauthorized Page');
        }

        return view('posts/edit')->with('post', $post);
    }

    /**
     * Update the specified resource in storage.
     */
    public function update(Request $request, string $id)
    {
        // Handle File Upload
        if($request->hasFile('cover_image')) {
            // Get filename with the extension
            $filenameWithExt = $request->file('cover_image')->getClientOriginalName();

            // Get just filename
            $filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);

            //get just ext
            $extension = $request->file('cover_image')->getClientOriginalExtension();

            // Filename to store
            $fileNameToStore = $filename.'_'.time().'.'.$extension;

            // Upload the Image
            $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);
        }

        $post = Post::find($id);
        $post->title = $request->input('title');
        $post->description = $request->input('description');
        $post->body = $request->input('body');
        $post->user_id = auth()->user()->id;

        if ($request->hasFile('cover_image')) {
            $post->cover_image = $fileNameToStore;
        }

        $post->save();

        return redirect('/posts')->with('success', 'Post Updated');
    }

    /**
     * Remove the specified resource from storage.
     */
    public function destroy(string $id)
    {
        $post = Post::find($id);

        // Check for correct user to prevent unauthorized editing
        if (auth()->user()->id !== $post->user_id) {
            return redirect('/posts')->with('error', 'Unauthorized Page');
        }

        if ($post->cover_image != 'noimage.') {
            //Delete
            Storage::delete('public/cover_images/'.$post->cover_image);
        }

        $post->delete();

        return redirect('/posts')->with('success', 'Post Removed');
    }
}

这是错误的屏幕截图：

我尝试过更改第 133 行：

$post->body = $request->input('body');

对此：

$post->body = $request->input('body')->nullable();

这是编辑表格。我正在使用CKeditor5:

编辑帖子

{{-- The Editor --}}
{!! Form::open(['action' => ['App\Http\Controllers\PostsController@update', $post->id], 'enctype' => 'multipart/form-data']) !!}
    <div class="form-group" style="margin-bottom: 20px;">
        {{ Form::text('title', $post->title, ['class' => 'form-control', 'placeholder' => 'Title']) }}
    </div>
    <div class="form-group" style="margin-bottom: 20px;">
        {{ Form::text('description', $post->description, ['class' => 'form-control', 'placeholder' => 'Description']) }}
    </div>
    <div class="form-group">
        {{ Form::file('cover_image') }}
    </div>
    <div class="form-group">
        {{ Form::textarea('body', '', ['class' => 'form-control', 'style' => 'margin-top: 20px;']) }}
    </div>
    {{ Form::hidden('_method', 'PUT')}}
    {{ Form::submit('Submit', ['class' => 'btn btn-primary', 'style' => 'width: 100px; height: 40px; margin-top: 20px;']) }}
    {{ Form::submit('Delete', ['class' => 'btn btn-danger', 'style' => 'width: 100px; height: 40px; margin-top: 20px;']) }}
{!! Form::close() !!}

这是帖子模型：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    protected $fillable = [
        'user_id',
        'body',
    ];

    //Table Name
    protected $table = 'posts';
    // Primary Key
    public $primaryKey = 'id';
    // Timestamps
    public $timestamps = true;

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

@lagbox 在评论中为我指明了正确的方向。

我完全忘记修改表单来请求数据。它与模型或控制器无关。检查一下你的 JavaScript 人员！

表格：

<div class="form-group">
    {{ Form::textarea('body', '', ['class' => 'form-control', 'style' => 'margin-top: 20px;']) }}
</div>

至：

<div class="form-group">
    {{ Form::textarea('body', $post->body, ['class' => 'form-control', 'style' => 'margin-top: 20px;']) }}
</div>
