Hello,
I am new to meteor and In my web app (Meteor 1.2.1) the users can make posts and under the posts can make comments. I am pushing the comments into the comment array in the post collection but the code updates the array only when me as the owner of post i make a comment in my own post. If i try to make a comment in someone’s else post the array updates with an empty string. The second is that i want to update the commentUsers array which holds the user who made a comment. This works but it updates the array with all the information of the user, i just want the username. And the third is i don’t know how to access the comments array of a certain post and display the results on the screen.
Here is the code:
postComments.js:
Template.commentForm.events({
'submit .comment-form': function(event){
event.preventDefault();
var content = document.getElementsByClassName('form-comment')[0].value;
console.log(content);
var user = Meteor.user();
var username = user.username;
console.log(username);
Meteor.call('comment', this, content, user);
}
});
methods.js:
Post = new Mongo.Collection('post');
Meteor.methods({
addPost: function(content){
if(!Meteor.userId()){
throw new Meteor.Error('not-authorized', 'you are not signed');
}
var username = Meteor.user().username;
Post.insert({
content: content,
created: new Date(),
username: username,
comments: [],
commentUsers: []
});
},
follow: function(post){
console.log(post);
var user = Meteor.user();
if(!Meteor.userId()){
throw new Meteor.Error('not-authorized', 'you are not signed');
}
if(user.username != post.username && user.profile.follow.indexOf(post.username) == -1) {
//if everything is correct then we will update the current user and will push
//the to the array the new user name which we are taking his information from the post
Meteor.users.update({_id: user._id},
{$push: {'profile.follow': post.username}
});
}
},
comment: function(post, content, username) {
console.log(post);
console.log(content);
//var user = Meteor.user();
if(!Meteor.userId()){
throw new Meteor.Error('not-authorized', 'you are not signed in');
}
Post.update({_id: post._id},
{$push: {'comments': content, 'commentUsers': username }}
//{$push: {'commentUsers': username }}
);
}
})
commentList.js:
Template.commentsList.helpers({
comments: function(postId){
var comments = Post.findOne({postId: postId})._id;
return comments.comments;
}
});
commentList.html:
<template name="commentsList">
<ul>
{{#each comment in comments}}
<li>{{comments _id}}</li>
{{/each}}
</ul>
</template>
Good catch!
