PUT方法抛出BadMethodCallException

Question

我正在从Lacast学习Laravel，并试图创建一个CRUD应用程序。我已经正确实现了index,show,create和store，但是当我使用edit形式时尝试提交引发BadMethodCallException的数据。 这是我的路线

Route::get('/projects','ProjectsController@index');
Route::get('/projects/{id}','ProjectsController@show')->where('id','[0-9]+');


Route::get('/create','ProjectsController@create');
Route::post('/projects','ProjectsController@store');

Route::get('/projects/{id}/edit','ProjectsController@edit')->where('id','[0-9]+');
Route::put('/projects/{id}','ProjectsController@update')->where('id','[0-9]+');

Route::delete('/projects/{id}','ProjectsController@destroy');

这是edit形式：

@extends('template');
@section('content')
    <h2>Create new project</h2>
<p>/projects/{{ $project->id }}</p>    
<form method="POST" action="/projects/{{ $project->id }}">
        {{ method_field('PUT') }}
        {{ csrf_field() }}
        <div>
            <input value="{{ $project->title }}" type="text" name="title" id="title" placeholder="Project title">
        </div>
        <div>
            <textarea  name="description" placeholder="Enter the project description">{{ $project->description }}</textarea>
        </div>
        <div>
            <button type="submit">Update project</button>
        </div>
    </form>
@endsection

控制器代码：

 public function edit($id){
        $project= Project::find($id);
        return view('projects.edit',compact('project'));
    }

    public function update($id){
        $project= Project::find($id);
        $project->title=request('title');
        $project->description('description');
        $project->save();
        return redirect('/projects');
    }

edit form的显示与来自数据库的数据一样，提交后得到以下错误页面：

以讲师的示例为例，代码运行良好，并且在我的表单和控制器中使用PUT之前，我都像讲师一样使用PATCH，但结果始终相同。

错误非常简单。

public function update($id){
    $project= Project::find($id);
    $project->title=request('title');
    $project->description('description'); // You don't have a method description()
    $project->save();
    return redirect('/projects');
}

这可能就是您要做的：

public function update($id)
{
    $project= Project::find($id);

    $project->title = request('title');
    $project->description = request('description');
    $project->save();

    return redirect('/projects');
}
