Laravel 編集機能を使った時に行が1行増えてしまう問題について

はじめに

Laravelの~Controller@updateを使用した時に
編集した値が編集前のデータと編集後のデータの2つが登録されて
しまいにっちもさっちも行かない方向けの記事になります。

以下では、ユーザーが書いた記事を編集するというプロジェクトについてのcontroller,viewになります。

コード

controller

PostsController.php
public function update(Request $request, $post_id){
        $params = $request->validate([
            'title'=>'required|max:50',
            'body'=>'required|max:2000',
        ]);
        $post = Post::findOrFail($post_id);
        $post->fill($params)->save();

        return redirect()->route('posts.show',['post'=>$post]);
    }

view

view/edit.blade.php

    <div class="container mt-4">
        <div class="border p-4">
            <h1 class="h5 mb-4">投稿の編集</h1>
        </div>
        <form action="{{route('posts.update',['post'=>$post])}}"method="POST">
            @csrf
            @method('PUT')
            <fieldset class="mb-4">
                <div class="form-group">
                    <label for="title">タイトル</label>
                    <input type="text"id="title"name="title"class="form-control {{ $errors->has('title')?'is-invalid':''}}"value="{{old('title')?:$post->title}}">
                    @if($errors->has('title'))
                        <div class="invalid-feedback">
                            {{$errors->first('title')}}
                        </div>
                    @endif
                </div>
                <div class="form-group">
                    <label for="body">本文</label>
                    <textarea name="body" id="body" class="form-control {{$errors->has('body')?'is-invalid':''}}" rows="4">
                        {{old('body')?:$post->body}}
                    </textarea>
                    @if($errors->has('body'))
                        <div class="invalid-feedback">
                            {{$errors->first('body')}}
                        </div>
                    @endif

                    <div class="mt-5">
                        <a class="btn btn-primary"href="{{route('posts.show',['post'=>$post])}}">キャンセル</a>
                        <button type="submit"class="btn btn-primary">更新する</button>
                    </div>
                </div>

            </fieldset>

@method('PUT')を入れるのがポイントです。

routing

ちなみにroutes/web.phpは

routeweb.php


Route::resource('posts', 'PostsController', ['only' => ['create', 'store', 'show','edit','update','destroy']]);

$ php artisan route:list
+--------+-----------+-------------------+----------------+-----------------------------------------------+--------------+
| Domain | Method    | URI               | Name           | Action                                        | Middleware   |
+--------+-----------+-------------------+----------------+-----------------------------------------------+--------------+
|        | GET|HEAD  | /                 | top            | App\Http\Controllers\PostsController@index    | web          |
|        | GET|HEAD  | api/user          |                | Closure                                       | api,auth:api |
|        | POST      | comments          | comments.store | App\Http\Controllers\CommentsController@store | web          |
|        | POST      | posts             | posts.store    | App\Http\Controllers\PostsController@store    | web          |
|        | GET|HEAD  | posts/create      | posts.create   | App\Http\Controllers\PostsController@create   | web          |
|        | GET|HEAD  | posts/{post}      | posts.show     | App\Http\Controllers\PostsController@show     | web          |
|        | PUT|PATCH | posts/{post}      | posts.update   | App\Http\Controllers\PostsController@update   | web          |
|        | DELETE    | posts/{post}      | posts.destroy  | App\Http\Controllers\PostsController@destroy  | web          |
|        | GET|HEAD  | posts/{post}/edit | posts.edit     | App\Http\Controllers\PostsController@edit     | web          |
+--------+-----------+-------------------+----------------+-----------------------------------------------+--------------+

こうなっています。

@method('PUT')を入れるか入れないかで、その後のデータが辿る経路が変わってしまうとは。。。
