Question

当我尝试编辑“Metier”时，会创建一个新的“Metier”，而旧的“Metier”保持不变。我想粉碎旧的“Metier”并通过编辑创建一个新的。这是我与编辑功能相关的代码。

控制器

 public function edit($id)
{
$metier=Metier::find($id);
return view('metier.edit',['libelle_metier'=>$metier]);
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
 public function update(Request $request, $id)
{
$metier=Metier::find($id);
return view('metier.edit',['libelle_metier'=>$metier]);
}

查看

 <div class="form-group">
 <label for="">libelle Metier </label>
 <input type="text"  name ="libelle_metier" class="form-control"value ="
 {{$libelle_metier->libelle_metier}}" >
 </div>

 <div class="form-group">
 <input type="submit" value = "enregistrer" class="form-control btn btn-
 primary">
 </div>

路线

Route::get('/metier', 'MetierController@index');
Route::get('/metier/create', 'MetierController@create');
Route::post('/metier', 'MetierController@store');
Route::get('/metier/{id}/show', 'MetierController@edit');
Route::get('/metier/{id}/edit', 'MetierController@edit');
Route::upd('/metier/{id}/update', 'MetierController@update');
Route::delete('/metier/{id}', 'MetierController@destroy')

MetierController.php

public function edit($id)
{
$metier=Metier::find($id);
return view('metier.edit',['libelle_metier'=>$metier]);
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function update(Request $request, $id)
{
    $metier = Metier::find($id);
    $metier->libelle_metier = $request->libelle_metier;
    $metier->save();
    return back();
}

将{{ method_field('PATCH') }}添加到您的表单并将操作更改为命名路由并将metier id传递给它。

 @extends('Layouts/app')
@extends('Layouts.master')
@section('content')
<div class="container">
    <div class="row">
        <div class="col-md-10">
            <h1>Modifier Metier </h1>

        <form action="{{ route('metier.update', $libelle_metier->id) }}" method="post">
            {{csrf_field()}}
            {{ method_field('PATCH') }}



            <div class="form-group">
             <label for="">libelle Metier </label>
             <input type="text"  name ="libelle_metier" class="form-
control"value ="
             {{$libelle_metier->libelle_metier}}" >
             </div>

             <div class="form-group">
             <input type="submit" value = "enregistrer" class="form-control 
btn btn-
             primary">
             </div>
        </form>
    </div>
</div>
@endsection

路线档案

Route::patch('/metier/{id}/update', 'MetierController@update')->name('metier.update');

提示：删除所有这些

Route::get('/metier', 'MetierController@index');
Route::get('/metier/create', 'MetierController@create');
Route::post('/metier', 'MetierController@store');
Route::get('/metier/{id}/show', 'MetierController@edit');
Route::get('/metier/{id}/edit', 'MetierController@edit');
Route::upd('/metier/{id}/update', 'MetierController@update');
Route::delete('/metier/{id}', 'MetierController@destroy')

并将其全部添加为单个资源，以便一次性添加所有REST URL。如果它的REST规范应该如何。阅读 REST Resource Naming Guide和here

Route::resource('metier', 'MetierController');

或以这种方式添加而不是资源

Route::get('/metier', 'MetierController@index')->name('metier.index');
Route::get('/metier/create', 'MetierController@create')->name('metier.create');
Route::post('/metier', 'MetierController@store')->name('metier.store');
Route::get('/metier/{id}', 'MetierController@show')->name('metier.show');
Route::get('/metier/{id}/edit', 'MetierController@edit')->name('metier.edit');
Route::patch('/metier/{id}', 'MetierController@update')->name('metier.update');
Route::delete('/metier/{id}', 'MetierController@destroy')->name('metier.destroy');

了解Resource Controllers

控制器

public function edit($id)
{
    $metier=Metier::find($id);
    return view('metier.edit',['libelle_metier'=>$metier]);
}

public function update(Request $request, $id)
{
    // do some request validation
    $metier=Metier::find($id);
    $metier->update($request->all());
    return redirect()->route('metier.show', $metier->id);
}

如果你有质量分配错误。

将protected $guarded = [];添加到Metier模型

编辑“Metier”时会创建新的“Metier”
