Laravel 8:缺少[路由:编辑问题][URI:编辑问题/{问题}][缺少参数:问题]的必需参数
我正在使用Laravel 8开发我的论坛项目,在此项目中,我想创建一个editquestion
页面,用户可以编辑他们的问题。
<form action="{{ route('edit.question', $show->slug) }}">
<button type="submit" class="text-blue-500">Edit Question</button>
</form>
这是显示editquestion
刀片的路径:
Route::get('editquestion/{question:slug}' , [QuestionController::class, 'editQuestion'])->name('edit.question');
这是控制器方法editQuestion()
,它返回刀片:
public function editQuestion(Question $slug)
{
return view('questions.editquestion',[
'slug' => $slug
]);
}
但现在,每当我单击Edit Question
时,我都会收到以下错误:
缺少[Route:edit.Quest][URI:editQuery/{Quest}][缺少参数:Query]
那么这里出了什么问题呢?我如何解决此问题?
如果您能就此分享您的想法或建议,我将不胜感激…
提前感谢。
更新#1:
我添加了slug
的隐藏输入:
<form action="{{ route('edit.question') }}" method="POST">
@csrf
<input type="hidden" value="{{ $show->slug }}" />
<button type="submit" class="text-blue-500">Edit Question</button>
</form>
并收到此错误:
Missing required parameter for [Route: edit.question] [URI: editquestion/{slug}] [Missing parameter: slug]. (View: F:xampphtdocsgooyanetootesourcesviewsquestionsquestion.blade.php)
更新#2:
这里是web.php
路由:
Route::middleware('auth')->group(function() {
Route::get('logout', [LoginController::class, 'logout']);
Route::resource('profile' , ProfileController::class);
Route::get('ask' , [QuestionController::class, 'showForm'])->name('ask');
Route::post('ask' , [QuestionController::class, 'postForm']);
Route::get('questions/{slug}' , [QuestionController::class, 'showQuestion']);
Route::post('questions/{question}/answer' , [QuestionController::class, 'postAnswer'])->name('questions.answers');
Route::get('answers/{ans}' , [QuestionController::class, 'editAnswer'])->name('edit.answer');
Route::get('editquestion/{slug}' , [QuestionController::class, 'editQuestion'])->name('edit.question');
Route::post('editquestion/{id}' , [QuestionController::class, 'updateQuestion'])->name('update.question');
Route::post('questions/{ans}' , [QuestionController::class, 'updateAnswer'])->name('update.answer');
Route::delete('questions/{ans}' , [QuestionController::class, 'destroyAnswer'])->name('destroy.answer');
Route::delete('{id}' , [QuestionController::class, 'destroyQuestion'])->name('destroy.question');
});
解决方案

public function editQuestion(Question $slug)
{
return view('questions.editquestion',[
'slug' => $slug
]);
}
您正在editQuery(路由-模型绑定)中注入Question model
,因此您还应该在窗体中传递问题类实例。
<form action="{{ route('edit.question', $show) }}">
<button type="submit" class="text-blue-500">Edit Question</button>
</form>
或
<form action="{{ route('edit.question', ['question' => $show]) }}">
应该可以正常工作。
