UrlGenerationException（[路由]缺少必需的參數）

Question

我不知道這個錯誤來自它說的地方。當我嘗試更新我的記錄時出現此錯誤。它正常工作，並更新到我的數據庫，但得到這個錯誤。它說，這在我的參數中漏掉了一些東西。我認爲我的錯誤是return redirect()->route('account.show');當我試圖重定向到我的顯示視圖更新後。但是當我重定向到其他工作正常。有什麼意見？

缺少[Route：account.show] [URI：show/{id}]的必需參數。

我有3個刀片模板。 搜索，編輯和顯示。

search.blade.php - 顯示所有記錄。

@foreach ($result as $row) 
    <tr class = "success"> 
     <td>{{ $row->id }}</td> 
     <td>{{ $row->first_name }}</td> 
     <td>{{ $row->last_name }}</td> 
     <td>{{ $row->middle_name }}</td> 
     <td>{{ $row->email }}</td> 
     <td>{{ $row->username }}</td> 
     <td> 
      <a href = "{{ route ('account.show', $row->id) }}"><button type = "submit" class = "btn btn-info">View</button></a> 

      <a href = "{{ route ('account.edit', $row->id) }}"><button type = "submit" class = "btn btn-warning">Edit</button></a> 

      <a href = "{{ route ('result.destroyEmployee', $row->id) }}"><button type = "submit" class = "btn btn-danger">Archive</button></a> 
     </td> 
    </tr> 
@endforeach 

edit.blade.php - 文本字段的只會地方 - 在這裏，我打提交按鈕，這是保存

<div class = "col-md-6"> 
<form class = "form-vertical" role = "form" method = "post" action = "{{ route ('account.edit', $result->id) }}"> 

<h3>Edit Employee</h3> 
<hr> 

<div class = "form-group"> 

    <label for = "email" class = "control-label">Email Address</label> 
    <input type = "text" name = "email" class = "form-control" value = "{{ $result->email }}"> 

</div> 

<div class = "form-group"> 

    <label for = "username" class = "control-label">Username</label> 
    <input type = "text" name = "username" class = "form-control" value = "{{ $result->username }}"> 

</div> 

<div class = "form-group"> 

    <button type = "submit" class = "btn btn-success">Save</button> 

</div> 

<input type = "hidden" name = "_token" value = "{{ Session::token() }}"> 

</form> 

show.blade.php後得到了錯誤記錄的值。

<div class = "col-md-6"> 
<form class = "form-vertical" role = "form" method = "post" action = "{{ route ('account.show', $result->id) }}"> 

<h3>View Employee</h3> 
<hr> 

<div class = "form-group"> 

    <label for = "email" class = "control-label">Email Address</label> 
    <input type = "text" name = "email" class = "form-control" placeholder = "{{ $result->email }}" readonly> 

</div> 

<div class = "form-group"> 

    <label for = "username" class = "control-label">Username</label> 
    <input type = "text" name = "username" class = "form-control" placeholder = "{{ $result->username }}" readonly> 

</div> 

<input type = "hidden" name = "_token" value = "{{ Session::token() }}"> 

</form> 

路線：

//READ 
Route::get('/search', 
[ 
    'uses' => '\App\Http\Controllers\AccountController@getEmployee', 
    'as' => 'account.search', 
]); 


//SHOW 
Route::get('/show/{id}', 
[ 
    'uses' => 'AccountController@showEmployee', 
    'as' => 'account.show', 
]); 

//EDIT 
Route::get('/edit/{id}', 
[ 
    'uses' => '\App\Http\Controllers\AccountController@editEmployee', 
    'as' => 'account.edit', 
]); 


//UPDATE 
Route::post('/edit/{id}', 
[ 
    'uses' => '\App\Http\Controllers\AccountController@updateEmployee', 
    'as' => 'account.edit', 
]); 

Answer 1

試圖改變這一點：

<form class = "form-vertical" role = "form" method = "post" action = "{{ route ('account.show', $result->id) }}"> 

要：

<form class = "form-vertical" role = "form" action="{{ url('edit/'. $result->id) }}" method="POST"> 

然後，您必須將路由參數作爲第二個參數傳遞給路由。事情是這樣的：return redirect()->route('account.show', [$id])

*我會建議你使用laravel集體形式：https://laravelcollective.com/

隨着laravel集體，你可以做這樣的事情：

{!! Form::open(array('route' => array('account.show', $result->id))) !!}
