Question

我正在使用Laravel 5.6，并将delete个用户从users表中用作admin。我具有以下 UserController 函数来删除表记录吗？

public function delete($id)
{
    User::where('id', $id)->delete();

    return redirect()
              ->back()
              ->with('info', 'User deleted successfully'); 
}

“我的用户”数据显示在索引刀片文件中，并带有如下删除按钮：

<td>
    <a class="button is-outlined" 
      href="{{route('users.index', $user->id.'/delete/')}}" 
      onclick="return confirm('Are you sure to want to delete this record?')"
     >
        Delete
     </a>
</td>

我的删除路线是这样的

Route::get('users/{users}/delete', [
    'uses' => '\App\Http\Controllers\UserController@delete',
]);

但现在我单击删除按钮javascript 确认通过，并且接受后仍然不会删除记录。网址更改如下：

http://localhost:8000/users?16/delete/     //16 is user id

如何解决此问题？

Answer 1

将路线更改为：

pids

更改以下行：

Route::get('users/{id}/delete', [
    'as' => 'users.delete','uses' => '\App\Http\Controllers\UserController@delete',
]);

TO

<td><a class="button is-outlined" href="{{route('users.index', $user->id.'/delete/')}}" onclick="return confirm('Are you sure to want to delete this record?')" >Delete</a></td>

Answer 2

您可以尝试销毁类似的方法

User::destroy($id)

Answer 3

在您的web.php路由文件中，您通过了{users}，而没有通过{id}：

Route::get('users/{id}/delete', [
    'uses' => '\App\Http\Controllers\UserController@delete',
])->name('user.delete');

在刀片视图中：

<td><a class="button is-outlined" href="{{route('users.delete',['id' => $user->id])}}" onclick="return confirm('Are you sure to want to delete this record?')" >Delete</a></td>`

在您的控制器中：

public function delete($id)
{
        User::where('id', $id)->delete();
        // or you can use User::destroy($id);
        return redirect()->back()->with('info', 'User deleted successfully'); 
}

Answer 4

将路线更改为：

Route::get('users/{id}/delete', [
    'uses' => '\App\Http\Controllers\UserController@delete',
]);

然后检查您的数据库表是否已删除该用户。如果不是这样，那么我认为这是您数据库中的CI违规，仅因为用户ID是另一个表中的外键，您就不能删除它。

我会将您的route.php file更改为一种更简单的方法，有助于您理解：

Route::get('users/{id}/delete', 'UserController@delete')
->where(['id', => '[0-9]+'])
->name('user.delete');

在上面的路线上，您已经确保它仅接受id是数字的请求。另外，您可以为路由命名，以简化代码结构，因此，如果以后进行更改，则无需继续在表单中进行更改

然后，您表单上的路线生成也会对其进行更改：

href="{{route('user.delete', ['id' => $user->id])}}"

然后您的控制器将更改为

public function delete($id)
{
    $user = User::find($id);

    //Having a hold on your user model makes it able to also delete any other relationship it might have, if you so wish
    $user->delete();

    return redirect()
              ->back()
              ->with('info', 'User deleted successfully'); 
}

为什么没有在Laravel 5.6中删除表中的用户
