我试图像这样更新数据透视表:
public function updatePermission($id, $permissionId)
{
$permissionValue = Input::get('value');
$user = User::find($id);
$perms = ['value' => $permissionValue];
$user->permissions()->updateExistingPivot($permissionId, $perms);
}
此枢轴先前已使用以下命令创建:
public function attachPermission($id)
{
$permissionId = Input::get('id');
$permissionValue = Input::get('value');
$user = User::find($id);
if (!$user->permissions->contains($permissionId)) {
$user->attachPermissionById($permissionId);
$perms = ['value' => $permissionValue];
$user->permissions()->updateExistingPivot($permissionId, $perms);
} else {
return Response::json(array('error' => 'Permission ' . $permissionId . ' is alreay set for user ' . $user->id));
}
return Response::json(array('role' => User::with(['roles.permissions', 'permissions', 'students'])->find($user->id)));
}
当命中updatePermission()方法时,它会正常传递,但它不会使用新值更新数据透视表。我在这里做错了什么?

我不会告诉你为什么它不起作用,但我建议你这样做:
public function attachPermission($id)
{
$permissionId = Input::get('id');
$value = Input::get('value');
$user = User::find($id);
$sync = $user->permissions()->sync([$permissionId => compact('value')], false);
return (in_array($permissionId, $sync['updated']))
? Response::json(...) // permission updated
: Response::json(...); // permission added
}
它会为您添加或更新新权限。
