back4app 解析，如何将用户对象 ID 应用到另一个类指针中

问题描述

这是我的代码

void SignBusiness() async {
ParseUser currentUser = await ParseUser.currentUser() as ParseUser;
var nr = await currentUser.get('objectId');
ParSEObject Data = await ParSEObject('Business')
  ..set('NamaBisnis',_nama)
  ..set('AlamatBisnis',_alamat)
  ..set('KiloSampah',_kilo)
  ..set('Pemilik',nr);
await Data.save();
Navigator.pushNamedAndRemoveUntil(context,'/home',(route) => false);

}

这段代码运行良好，这是运行的结果

事实证明 POINTER COLUMN 不能填充 USER OBJECT ID.. 即使它们是正确的代码来填充。所以任何人都可以帮助解决这个问题？请..

解决方法

您需要传递对象（不仅是 id）。应该是这样的：

void SignBusiness() async {
ParseUser currentUser = await ParseUser.currentUser() as ParseUser;
ParseObject Data = await ParseObject('Business')
  ..set('NamaBisnis',_nama)
  ..set('AlamatBisnis',_alamat)
  ..set('KiloSampah',_kilo)
  ..set('Pemilik',currentUser);
await Data.save();
Navigator.pushNamedAndRemoveUntil(context,'/home',(route) => false);
