我有2个模型，用户，角色和数据透视表。在数据透视表中可见对用户的所有指定角色（user_id | role_id）当前，在控制器中，每行都有自己的提交按钮，用于将角色提交给数据库。我只做了一个按钮，但是它不起作用，它抛出异常“模型[App \ User]没有查询结果”。另外，我正在使用ajax，但是您将在下面的代码中看到所有内容。
我将其分开，因为generateUserTable也连接到destroy和action方法。按钮在generateUserTable中-
<td><button type="button" id="potvrdi" class="potvrdi-button btn btn-primary" data-id="'.$row->id.'">
<div class="potvrdi">Potvrdi</div>
</button></td>
控制器-
public function postUserRole(Request $request)
{
if ($request->ajax()) {
$loged_in_user = User::findOrFail(Auth::user()->id);
$user = User::findOrFail($request->get('id'));
$r1 = Role::find(1);
$r2 = Role::find(2);
if ($loged_in_user->IsAdmin()) {
if ($request->get('admin_role')==1) {
$user->roles()->attach($r1);
} else {
$user->roles()->detach($r1);
}
if ($request->get('korisnik_role')==1) {
$user->roles()->attach($r2);
} else {
$user->roles()->detach($r2);
}
}
$data = User::all();
return json_encode($this->generateUserTable($data));
}
}
public function generateUserTable($data)
{
// return User::find(5)->roles;
$total_row = $data->count();
$output = "";
if ($total_row > 0) {
foreach ($data as $row) {
$roleNames = '';
$userRoles = $row->roles()->pluck('id')->toArray();
foreach (Role::all() as $roles1) {
$checked = '';
// var_dump($userRoles);
// var_dump($roles1->id);
// var_dump($roles1);
if (in_array($roles1->id, $userRoles, true)) {
$checked = 'checked="checked"';
}
$roleNames .= $roles1->role != null ? $roles1->role.' '.'<input type="checkbox" '.$checked.' name="role" value="'.$roles1->id.'" class="checkbox'.$roles1->id.'" id="'.$roles1->id.'">'.' ' : '';
}
$output .= '
<tr>
<td>'.$row->surname.'</td>
<td>'.$row->name.'</td>
<td>'.$row->phone.'</td>
<td>'.$roleNames.'</td>
<td><button type="button" id="potvrdi" class="potvrdi-button btn btn-primary" data-id="'.$row->id.'">
<div class="potvrdi">Potvrdi</div>
</button></td>
<td><button type="button" id="rowId" class="remove-button btn btn-danger" data-id="'.$row->id.'">
<div class="close">x</div>
</button></td>
</tr>
';
}
} else {
$output = '
<tr>
<td align="center" colspan="5">Nema podataka</td>
</tr>
';
}
return array(
'table_data' => $output,
'total_data' => $total_row,
);
}
}
查看-这是我希望“转移”提交按钮的地方。我把它放在桌子后面。正在查看脚本，用于向数据库提交用户角色的ajax是第二个。

我仍然是初学者，因此我对意大利面条代码表示歉意，我正在尽力而为。
谢谢
