当我想从包含 ParseRelation 的子类中检索 ParseObjects 时遇到问题
当此代码运行时:
public void loadProjectsForCurrentUser() {
User currUser = UserManager.Instance.CurrentUser;
if (currUser != null) {
currUser.Projects.Query.FindAsync().ContinueWith(t => {
if(onProjectsLoaded != null) {
onProjectsLoaded(new List<Project>(t.Result));
}
});
} else {
Debug.LogWarning("Trying to load projects while not logged in!");
}
}
我收到此错误:
错误消息:创建 ParseQuery 时必须指定 ParseObject 类名。参数名称:类名
这是我的子类的一部分:
[ParseFieldName(PARSE_VALUES.Projects)]
[CoherentProperty]
public ParseRelation<Project> Projects {
get { return GetRelationProperty<Project>("Projects"); }
}
当用户登录时,我创建了一个新的用户实例,并获取如下数据:
User currUser = ParseUser.CreateWithoutData<User>(ParseUser.CurrentUser.ObjectId);
currUser.FetchIfNeededAsync().ContinueWith(userResult => {
Debug.Log("Fetched User");
currUser.Company.FetchIfNeededAsync().ContinueWith(companyResult => {
Debug.Log("Fetched Company");
UserManager.Instance.CurrentUser = currUser;
ParentView.TriggerEvent("login", UserManager.Instance.CurrentUser);
ProjectManager.Instance.loadProjectsForCurrentUser();
if (onLogin != null)
onLogin();
});
});
我已经找到了这个页面: https ://www.parse.com/questions/error-when-querying-relational-data-in-unity
这是堆栈跟踪,可能包含有趣的信息:

但我似乎找不到错误......任何可以帮助的人?
