I am new to meteor and got stucked and can't understand what am I doing wrong. Enlighten me please.
Here is the HTML file:
<body>
<h1>Do</h1>
{{#if activeTask}}
{{> currentTask}}
{{else}}
{{> newTask }}
{{/if}}
<div>
</div>
</body>
<template name="newTask">
<form>
<label>What<input type="text" name="what" placeholder="gimme an action"/></label>
<input type="submit" value="Go"/>
</form>
<!--
{{> inputAutocomplete settings=settings id="msg" class="input-xlarge" placeholder="action"}}
-->
</template>
<template name="currentTask">
<form>
<label>What<input type="text" name="what" placeholder="gimme an action"/>{{activeTask.what}}</label>
<div>4h 15m</div>
<input type="submit" value="Stop"/>
</form>
</template>
And here is the JavaScript file:
tasks = new Mongo.Collection('tasks');
if (Meteor.isClient) {
Template.body.helpers({
activeTask: function() {
var task = tasks.findOne(
{
endAt: null
},
{
sort: {
startAt: -1
}
}
);
console.log(task);
return task;
}
});
Template.newTask.events({
'submit' : function(event) {
event.preventDefault();
var now = Date.now();
var what = event.target.what.value;
tasks.insert({ what: what, startAt: now, endAt: null });
}
});
}
It successfully adds a new document into the database and logs this in the helper activeTask. One step later it logs no task at all. It has gone. But why?
If you don't have the package autopublish (https://atmospherejs.com/meteor/autopublish) installed, you need to create a publication (client-side) and subscription (server-side):
if (Meteor.isServer) {
Meteor.publish('tasks', function () {
return tasks.find();
});
}
if (Meteor.isClient) {
Meteor.subscribe('tasks');
}
I've also explained working with collections in a recent blog article.

I have a search facility in my project and I need to be able to publish results without using autopublish.
html
<template name="search">
<form id="searchform">
<input type="text" id="kategori" placeholder="Sila masukkan maklumat carian."/>
<button>Carian</button>
</form>
<hr/>
<h3>Maklumat</h3>
<ol>
{{#each profil}}
<li>{{jenama}}</li>
{{/each}}
</ol>
</template>
js:
Template.search.events({
"submit #searchform": function (e) {
e.preventDefault();
Session.set("kategori", e.target.text.value);
}
});
Template.search.helpers({
profil: function() {
return Profil.find({
kategori: Session.get('kategori'),
});
}
});
You can simply subscribe to a filtered publication:
client:
Template.search.events({
"submit #searchform": function (e) {
e.preventDefault();
Session.set("kategori", e.target.text.value);
Meteor.subscribe('profiles',Session.get('kategori'));
}
});
server:
Meteor.publish('profiles',function(kategori){
return Profil.find({ kategori: kategori });
});
If you don't have any other subscriptions to the same collection you can also simplify your helper to:
Template.search.helpers({
profil: function() {
return Profil.find();
}
});
Since the set of documents will be defined by your publication.
In practice though you usually use the same search in your helper as you do in the publication just to avoid documents from other publications showing up.
I want to insert a new document into db using autoform. Autoform hook calls a meteor method on server to insert the document.
I have this in template...
{{#autoForm collection="Reports" id="addReport" type="insert"}}
<div class="row">
<div class="col s6">
{{> afQuickField name='hours'}}
</div>
</div>
<button class="btn waves-effect waves-light modal-action modal-close"><i class="material-icons">save</i></button>
{{/autoForm}}
Then...
AutoForm.hooks({
addReport: {
onSubmit: function(insertDoc) {
Meteor.call('addReport', insertDoc, function(error, result) {
if (error) alert(error.reason);
});
return false;
}
}
});
then the method on server...
Meteor.methods({
addReport: function(insertDoc) {
var report = _.extend(insertDoc, {
userId: Meteor.userId(),
});
return Reports.insert(report);
}
});
I have a createdAt and updatedAt fields in collection, but they all have autoValue thus, I believe no need to do insertion from client or in the meteor method.
So collection with schema looks like this:
Reports = new Meteor.Collection('reports');
Reports.attachSchema(new SimpleSchema({
hours: {
type: Number,
label: "Number of hours",
decimal: true
},
createdAt: {
type: Date,
label: "Created Date",
autoValue: function() {
if (this.isInsert) {
return new Date;
} else {
this.unset();
}
},
denyUpdate: true
},
updatedAt: {
type: Date,
autoValue: function() {
if (this.isUpdate) {
return new Date()
}
},
denyInsert: true,
optional: true
},
"userId": {
type: String,
autoform: {
type: "hidden",
}
},
}));
When i run meteor, form displays, but submit does nothing. No visual cue as to if any error. No error message in both client and server console.
what am I doing wrong or missing?
Since #Cristo GQ got it right, I just want to make sure the answer is clear enough for future visitors of this thread
The onSubmit hook will be used only for autoForms with type='normal' or without any type= at all
On another note, the before.insert hook is just for type='insert' And there is no before.normal hook
This mean that when using the onSubmit hook, we have to do any "before work" (like adding currentUser to the doc) inside the onSubmit itself.
aldeed/meteor-autoform documentation:
// Called when form does not have a `type` attribute
onSubmit: function(insertDoc, updateDoc, currentDoc) {
Meteor.call()...
}
I'm following discovermeteor book, and I'm trying to use some methods of the book, but using the meteor-autoform package.
post_submit.html
<template name="postSubmit">
{{#autoForm collection="Posts" id="insertPost"}} <-- no type
<div class="form-group">
<div class="controls">
{{> afQuickField name='title' class='title form-control'}}
</div>
</div>
<div class="form-group">
<div class="controls">
{{> afQuickField name='description' class='description form-control'}}
</div>
</div>
<input id="send" type="submit" value="Send" class="btn btn-primary"/>
{{/autoForm}}
</template>
post_submit.js
var postSubmitHook = {
onSubmit: function(insertDoc){
Meteor.call('postInsert', insertDoc, function(error, result) {
if (error){
Bert.alert(error.reason, 'danger', 'growl-top-right');
$('#send').removeAttr('disabled');
return;
}
Router.go('postPage', {_id: result._id});
});
return false;
}
};
AutoForm.addHooks('insertPost', postSubmitHook);
I am having collection issues in my Meteor project. I added the following code to my Resolutions.js file:
Resolutions = new Mongo.Collection('resolutions');
if (Meteor.isClient) {
Template.body.helpers({
resolutions: function() {
Resolutions.find({});
}
});
Template.body.events({
'submit .new-resolution': function(event) {
var title = event.target.title.value;
Resolutions.insert({
title: title,
createdAt: new Date()
});
event.target.title.value = "";
return false;
}
});
}
if (Meteor.isServer) {
Meteor.startup(function () {
// code to run on server at startup
});
}
and added the following to my Resolutions.html file:
<head>
<title>Resolutions</title>
</head>
<body>
<div class="container">
<header>
<h1>Monthly Resolutions</h1>
<form class="new-resolution">
<input type="text" name="title" placeholder="A new resolution" />
<input type="submit" value="Submit"/>
</form>
</header>
<ul>
{{#each resolutions}}
{{> resolution}}
{{/each}}
</ul>
</div>
</body>
<template name="resolution">
<li>{{title}}</li>
</template>
After running the app I get zero errors but still the site does not return any of the collection value. I have no clue what is wrong with this project.
Template.body.helpers({
resolutions: function() {
return Resolutions.find({});
}
});
You forgot to use the return keyword.Remember that when creating a helper, you always need to return a value.
Having trouble trying to pass some sort of context into my little test chan-clone.
Problem is I have threads, with replies. Showing just the threads works great, showing threads with replies based upon the threads they come from not so much.
Question is how do I send context on the outer each. Thank you so much for the help!

meteorchan.js
Threads = new Mongo.Collection("threads");
Replies = new Mongo.Collection("replies");
if (Meteor.isClient) {
Meteor.subscribe("threads");
Template.body.helpers({
threads: function () {
return Threads.find({}, {sort: {createdAt: -1}});
},
replies: function () {
return Replies.find({}, {sort: {createdAt: 1}});
}
});
Template.body.events({
"submit .new-thread": function (event) {
event.preventDefault();
var text = event.target.text.value;
var currentId = 0;
if(Threads.findOne({}, {sort: {createdAt: -1}})){
currentId = Threads.findOne({}, {sort: {createdAt: -1}}).iden;
}
Threads.insert({
text: text,
createdAt: new Date(),
iden: currentId + 1
});
event.target.text.value = "";
},
"submit .new-reply": function (event) {
event.preventDefault();
var text = event.target.text.value;
var thread = event.target.thread.value;
Replies.insert({
text: text,
createdAt: new Date(),
parentThread: thread
});
event.target.text.value = "";
}
});
Template.thread.events({
"click .purge": function (){
Threads.remove(this._id);
},
"submit .new-reply": function(event){
event.preventDefault();
},
"click .reply": function(){
$('.'+this._id+'.new-reply').css('display','inherit');
}
});
}
if (Meteor.isServer) {
Meteor.publish("threads", function () {
return Threads.find();
});
Meteor.publish("replies", function () {
return Replies.find();
});
}
You can refer to the context in the template helper using this.
So in your replies helper this refers to the current thread you are iterating over using the each.
You can do the following to only fetch replies for the corresponding thread:
replies: function () {
return Replies.find({
// this refers to the current thread
parentThread: this._id
}, {sort: {createdAt: 1}});
}
I successfully implemented a form with quill wysiwyg but now I want to create a component to reuse it. This is my working implementation:
<template name="form">
<form>
<div id="toolbar"> ... html with toolbar buttons </div>
<div id="editor"></div>
<input type="submit" value="save"/>
</form>
</template>
Template.form.rendered = function () {
this.quill = new Quill('#editor', {
modules: {
'toolbar': { container: '#toolbar' },
'link-tooltip': true
},
theme: 'snow' }
);
}
Template.form.events({
'submit form': function(e, tmpl) {
e.preventDefault();
var html = tmpl.quill.getHTML();
// code to save the form data
}
This is what I want to make it reusable. My questions are inside the code:
<template name="form">
<form>
{{> editor }}
<input type="submit" value="save"/>
</form>
</template>
<template name="editor">
<div id="toolbar"> ... html with toolbar buttons </div>
<div id="editor"></div>
</template>
Template.editor.rendered = function () {
this.quill = new Quill('#editor', {
modules: {
'toolbar': { container: '#toolbar' },
'link-tooltip': true
},
theme: 'snow' }
);
// How can I pass quill to the parent template?
}
Template.form.events({
'submit form': function(e, tmpl) {
e.preventDefault();
// How can I access quill variable on the nested template, so I can
// call quill.getHTML()?
}
Here's a pattern I use to solve this sort of problem. Define a class called Editor and a template editor. The intention is that the data context inside editor will be an instance of Editor.
function Editor() {
this.quill = null;
}
Template.editor.rendered = function () {
this.data.quill = new Quill(...);
}
<template name="editor">...</template>
Inside form's created callback, create an Editor and store it on the template instance. Then when you call out to the editor template, pass in the Editor instance as the data context.
Template.form.created = function () {
this.editor = new Editor();
}
Template.form.helpers({
editorInstance: function () {
return Template.instance().editor;
}
});
<template name="form">
<form>
{{> editor editorInstance }}
<input type="submit" value="save"/>
</form>
</template>
You can then define methods on the Editor prototype which can be called by the form:
Editor.prototype.getTextAsHTML = function () {
return this.quill && this.quill.getHTML();
}
Template.form.events({
"submit form": function(e, tmpl) {
e.preventDefault();
var html = tmpl.editor.getTextAsHTML();
// ...
}
}
This is a nice way to abstract the details of the editor so that the form doesn't need to know about it. You can reuse the editor and if you ever want to change it, you just have to make sure getTextAsHTML works the same.
