【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

I/flutter (14263): ╭-- Parse Request

原来指针列不能填充用户对象 ID.. 即使它们是要填写的正确代码。所以任何人都可以帮助解决这个问题吗？请...

【参考方案1】：

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);
