I am using meteor to build a website similar to reddit. I used the account-ui package for user accounts, but I had trouble getting the user value. I was able to create an account and login, but when I post a comment, it shows that I am an anonymous user. Here's the code -
Template.registerHelper('getUser', function(user_id) {
var user = Meteor.users.findOne({_id: user_id});
if (user) {
return user.username;
}
else {
return "anon";
}
});
post a comment -
Template.comment_form.events({
"submit .js-save-comment-form":function(event){
if (Meteor.user()) {
// here is an example of how to get the comment out of the form:
var comment = event.target.comment.value;
console.log("The comment is: "+comment);
Comments.insert({
website: Router.current().params._id,
comment: comment,
createdOn: new Date(),
user: Meteor.user()._id
});
event.target.comment.value = "";
}
else {
alert('You need to be logged in to submit comments!');
}
return false; // stop the form submit from reloading the page
}
});
I was logged in as user test, but when I posted a comment, it shows it's posted by anon, which means the server didn't return the user value
See if this makes the usernames show up. It's not the production solution, but it should give you some idea what's going on if it works.
Meteor.publish(null, function () {
if (!this.userId) return null;
return Meteor.users.find({},{fields: {'username': 1, '_id': 1}});
});

I have a mobile app in development and I'm transforming one of the collections to get the user last seen time, avatar etc.
PlayerRecord.prototype = {
constructor : PlayerRecord,
getAssociatedUser: function () {
return Meteor.users.findOne( this.user_id );
},
lastSeenFormatted: function () {
var user = this.getAssociatedUser();
return (user && user.last_seen) ? user.last_seen : 'Never';
}
}
My problem is that, if the user last seen returns Never initially but then the user is seen, my string return over there is not updated...obviously.
How would you advise me to handle this situation?
Did you check whether any user had a value for last_seen? This field has to be explicitly published.
According to the Meteor docs (http://docs.meteor.com/#/full/meteor_user):
By default, the current user's username, emails and profile are
published to the client. You can publish additional fields for the
current user with:
// server
Meteor.publish("userData", function () {
if (this.userId) {
return Meteor.users.find({_id: this.userId},
{fields: {'last_seen': 1}});
} else {
this.ready();
}
});
// client
Meteor.subscribe("userData");
I sent enrollment email to the user and when he enters password and other details I'm trying to reset the password but it is throwing error
uncaught error extpected to find a document to change
As you can see in the mage
I've subscribed to the user record
my code
this.route('enroll', {
path: '/enroll-account/:token',
template: 'enroll_page',
onBeforeAction: function() {
Meteor.logout();
Session.set('_resetPasswordToken', this.params.token);
s = this.subscribe('enrolledUser', this.params.token).wait();
}
}),
After I'm displaying form and on the submit event
onSubmit: function(creds) {
var options = {
_id: Meteor.users.findOne()._id,
name: creds.name
}
var token=Session.get('_resetPasswordToken');
Meteor.call('updateUser', options, function(error, result) {
if(!error) {
Accounts.resetPassword(token, creds.password, function(error) {
if (error) {
toastr.error("Sorry we could not update your password. Please try again.");
return false;
}
else{
toastr.error("Logged In");
Router.go('/');
}
});
} else {
toastr.error("Sorry we could not update your password. Please try again.");
return false;
}
});
this.resetForm();
this.done();
return false;
}
Everything is working fine but resetpassword callback is not triggering and the above error is displaying in console.
my token is get deleted from the user record and I'm able to login using login form but
From the docs
Reset the password for a user using a token received in email. Logs the user in afterwards.
I'm not able to automatically login after resetting the password,above error is throwing
What am I missing here?
this.subscribe('enrolledUser', this.params.token).wait();
here you're subscribing using resetPassword token
when you call Accounts.resetPassword method the method will reset the password and delete the token from user record.
So your subscription is lost and there are no records available in client side to modify
(That is waht the error Expected to find a document to change)
Instead on first subscription save the user Id and subscribe to the user record using Id
so the subscription will not be lost
path: '/enroll-account/:token',
template: 'enroll_page',
onBeforeAction: function() {
Meteor.logout();
Session.set('_resetPasswordToken', this.params.token);
s = this.subscribe('enrolledUser', this.params.token).wait();
},
onAfterAction:function(){
if(this.ready()){
var userid=Meteor.users.findOne()._id;
Meteor.subscribe("userRecord",userid);
}
}
Alternatively, you could do something like as follows in your publication. This worked for me (but mine was a slightly more involved query than this).
Meteor.publish('enrolledUser', function (token) {
check(token, String);
return Meteor.users.find({
$or: [{
_id: this.userId
}, {
'services.password.reset.token': token
}]
});
});
From the docs, it says
Reset the password for a user using a token received in email. Logs the user in afterwards.
So basically, you have to subscribe to the logged in user after the fact as well. A little silly, but whatever.
In my application I want to seed the database with users and send them an enrollment link to activate their account (and choose a password). I also want them to verify/change some profile data.
On the server I seed the database like this:
Meteor.startup(function () {
if(Meteor.users.find().count() === 0) {
var user_id = Accounts.createUser({ email: 'some#email.com', profile: { some: 'profile' } });
Accounts.sendEnrollmentEmail(user_id);
}
})
The enrollment link is sent as expected, but I want to create a custom template for when the url in the email is clicked. Preferably handled by iron-router. (Not using the accounts-ui package).
I tried things like redirecting the user to a custom route like this:
var doneCallback, token;
Accounts.onEnrollmentLink(function (token, done) {
doneCallback = done;
token = token;
Router.go('MemberEnroll')
});
which is not working (it changes the url but not rendering my template)
I also tried to change the enroll URL on the server like this:
Accounts.urls.enrollAccount = function (token) {
return Meteor.absoluteUrl('members/enroll/' + token);
};
But when I do this, the Accounts.onEnrollmentLink callback does not fire.
Also, changing the URL is not documented so I'm not sure its a good practice at all.
Any help is appreciated.
In my application I'm doing like this
this.route('enroll', {
path: '/enroll-account/:token',
template: 'enroll_page',
onBeforeAction: function() {
Meteor.logout();
Session.set('_resetPasswordToken', this.params.token);
this.subscribe('enrolledUser', this.params.token).wait();
},
data: function() {
if(this.ready()){
return {
enrolledUser: Meteor.users.findOne()
}
}
}
})
As enrollment url is like this
http://www.yoursite.com/enroll-account/hkhk32434kh42hjkhk43
when users click on the link they will redirect to this template and you can render your template
In my publication
Meteor.publish('enrolledUser', function(token) {
return Meteor.users.find({"services.password.reset.token": token});
});
After taking the password from the user
Accounts.resetPassword(token, creds.password,function(e,r){
if(e){
alert("Sorry we could not reset your password. Please try again.");
}else{
alert("Logged In");
Router.go('/');
}
})
enroll link
Accounts.urls.enrollAccount = function (token) {
return Meteor.absoluteUrl('enroll-account/' + token);
};
Im afraid now isnt possible, what i did is changing the html and css using "rendered" function but it has some probs with delay
Meteor.startup(function(){
Template["_enrollAccountDialog"].rendered = function(){
document.getElementById('enroll-account-password-label').innerHTML = 'Escolha sua senha';
$('.accounts-dialog').css('background-color','#f4f5f5');
$('.accounts-dialog').css('text-align','center');
$('.accounts-dialog').removeAttr('width');
document.getElementById('login-buttons-enroll-account-button').className = ' create-account-button';
document.getElementById('login-buttons-enroll-account-button').innerHTML = 'Criar conta';
}
});
In my Meteor app I use the default accounts package, which gives me the default login and registration functionality. Now I want to add an extra field to user, say nickname, and for the logged in user the possibility to edit this information.
For editing the profile I suppose I should be doing something like this:
Template.profileEdit.events({
'submit form': function(e) {
e.preventDefault();
if(!Meteor.user())
throw new Meteor.Error(401, "You need to login first");
var currentUserId = this._id;
var user = {
"profile.nickname": $(e.target).find('[name=nickname]').val()
};
Meteor.users.update(currentUserId, {
$set: user
}, function(error){
if(error){
alert(error.reason);
} else {
Router.go('myProfile', {_id: currentUserId});
}
});
}
});
But I doesn't store the info if I look in Mongo. Also when showing the profile, {{profile.nickname}} returns empty. What is wrong here?
Edit: added collections\users.js to show permissions:
Meteor.users.allow({
update: function (userId, doc) {
if (userId && doc._id === userId) {
return true;
}
}
});
Meteor.users.deny({
update: function(userId, user, fieldNames) {
return (_.without(fieldNames, 'profile.nickname').length > 0);
}
});
Yeah, I believe that should do the job, although I haven't actually run the code. The idea is certainly right.
The main things to be aware of are:
The necessity to allow the user doc to be edited from the client with an appropriate Meteor.users.allow() block on the server, assuming you're going to remove the "insecure" package (which you need to before doing anything in production).
The fact that "by default the server publishes username, emails, and profile", so you'll need to write a Meteor.publish function on the server and subscribe to it if you want to expose any other fields within the user document to the client once you've removed the "autopublish" package (which again, you really should).
I'm building a messenger application, and before a conversation is created I want to verify if a user exists. If it does, then it will create the conversation. If not, then it should return an error. I've been working with this code on the server side but for some reason it won't work. I've tried many different tweaks, but this is basically my structure:
Meteor.methods({
createConversation: function(secondPerson) {
function doesUserExist(secondPerson) {
var userx = Meteor.users.findOne({username: secondPerson});
if (userx === secondPerson) {
return false;
} else {
return true;
}
}
if (doesUserExist()) {
Conversations.insert({
person1: Meteor.user().username,
person2: secondPerson
});
} else {
Conversations.insert({
person1: "didn't work"
});
}
}
});
The main point you were missing is that find returns a cursor, whereas findOne returns a document. Here is one way to implement the method:
Meteor.methods({
createConversation: function(username) {
check(username, String);
if (!this.userId) {
throw new Meteor.Error(401, 'you must be logged in!');
}
if (Meteor.users.findOne({username: username})) {
return Conversations.insert({
person1: Meteor.user().username,
person2: username
});
} else {
throw new Meteor.Error(403, username + " does not exist!");
}
}
});
Note the following features:
validates that username is a string
requires that the user be logged in to create a conversation
reduces the user existence check to a single line
returns the id of the new conversation
uses Meteor.Error with explanations which can be seen on the client
To use it just open your browser console and try making calls like:
Meteor.call('createConversation', 'dweldon', function(err, id){console.log(err, id);});
