我有這種情況,我一直在嘗試解決。作爲Meteor JS的新手,我很困惑如何更新記錄。我有2個模板AddSchoolLayout和Schoolcontactlayout,AddSchoollayout在Mongo數據庫中創建記錄,現在,爲同一所學校我想添加它的地址仍然在同一個數據庫NewSchoolDB,但當我試着這個我不斷收到關於錯誤ID的錯誤。我錯了什麼?我會很感激得到一個快速的專業幫助。謝謝。對不起,我的語言可能與Mongo不相關,我還是新鮮的,來自SQL背景。使用Meteor js將記錄保存到Mongo DB的相同集合中
這是記錄被保存的method.js。
//methods.js
if (Meteor.isServer) {
Meteor.methods({
SchoolRegister: function (phone, schoolemail) {
if (!Meteor.userId()) {
throw new Meteor.error('Not authorized');
return false;
}else{
NewSchoolDB.insert({
authorId: Meteor.userId(),
phone: phone,
schoolemail
});
}
}
});
}
這是保存一個新學校時
//add school
Template.AddSchoolLayout.events({
'submit .addnewschool': function (event, template) {
event.preventDefault();
var newschoolname = trimInput(event.target.newschoolname.value);
if (isNotEmpty(newschoolname)) {
Meteor.call('SchoolRegister', newschoolname,
function (error, response) {
if (error) {
Bert.alert(error.reason, 'danger', 'growl-top-right');
return false;
}else{
Bert.alert("School successfully created", "success", "growl-top-right");
FlowRouter.redirect('/schoolcontact');
}
});
}
return false;
}
});
這是我想更新的學校地址
//school contact
Template.SchoolContactLayout.events({
'submit .contactschool': function (event) {
event.preventDefault();
var phone = trimInput(event.target.phone.value);
if (isNotEmpty(phone)) {
Meteor.call('SchoolRegister', phone, function (error, response) {
if (error) {
Bert.alert(error.reason, 'danger', 'growl-top-right');
return false;
}else{
Bert.alert('School address updated successfully', 'success', 'growl-top-right');
FlowRouter.redirect('/logo-upload');
}
});
}
return false;
}
});
錯誤記錄在控制檯上

我認爲你的問題是在本質上是服務器上下文中使用Meteor.userID。這可能會產生問題,請閱讀:https://guide.meteor.com/accounts.html#current-user – mstorkson
