[英]Meteor.users.findOne() returns undefined but it's still working
我正在接觸meteor.js,我對某些事情感到很困惑。
我寫了一個新的集合:
sendEmailAfterNotification = function(comment) {
var post = Posts.findOne(comment.postId);
if (comment.userId !== post.userId) {
Meteor.call('sendEmail',
Meteor.users.findOne(post.userId).emails[0].address,
'automailer@yourdomain.com',
comment.author + ' answered on your post : ' + post.title,
'random bodytext');
}
};
我的流星控制台輸出完全沒問題我會得到:
I20160424-16:00:54.758(2)? ====== BEGIN MAIL #0 ======
I20160424-16:00:54.766(2)? (Mail not sent; to enable sending, set the MAIL_URL environment variable.)
I20160424-16:00:54.767(2)? MIME-Version: 1.0
I20160424-16:00:54.767(2)? From: automailer@yourdomain.com
I20160424-16:00:54.767(2)? To: test@testdomain.com
I20160424-16:00:54.767(2)? Subject: testuser answered on your post : foobar
I20160424-16:00:54.767(2)? Content-Type: text/plain; charset=utf-8
I20160424-16:00:54.767(2)? Content-Transfer-Encoding: quoted-printable
I20160424-16:00:54.767(2)?
I20160424-16:00:54.768(2)? random body text
I20160424-16:00:54.768(2)? ====== END MAIL #0 ======
但在我的瀏覽器中我仍然得到一個錯誤代碼:
模擬調用'commentInsert'的效果時出現異常TypeError:無法讀取未定義的屬性'emails'(...)TypeError:無法讀取未定義的屬性'emails'
函數在這里被調用: comments.js
Comments = new Mongo.Collection('comments');
Meteor.methods({
commentInsert: function(commentAttributes) {
check(this.userId, String);
check(commentAttributes, {
postId: String,
body: String
});
var user = Meteor.user();
var post = Posts.findOne(commentAttributes.postId);
if (!post)
throw new Meteor.Error('invalid-comment', 'You must comment on a post');
comment = _.extend(commentAttributes, {
userId: user._id,
author: user.username,
submitted: new Date()
});
// update the post with the number of comments
Posts.update(comment.postId, {$inc: {commentsCount: 1}});
// create the comment, save the id
comment._id = Comments.insert(comment);
// now create a notification, informing the user that there's been a comment
createCommentNotification(comment);
// send an email to the post owner - if it's not the owner
sendEmailAfterNotification(comment);
return comment._id;
}
});
Meteor.users.findOne(post.userId)
在客戶端上不起作用,因為客戶端僅在Meteor.users
集合中具有當前用戶的數據。 確保您的服務器端sendEmail
是查詢Meteor.users
而不是客戶端的。
Meteor.users在客戶端上工作,只是確保您已手動發布和訂閱Meteor.users.find({},{})
。
