I'm new to meteor,I have two collections named Employee and Visitors.and two templates Home and Print. i can get the id of the record from the button like this.
printVisitor:function(){
return Visitor.findOne({_id:Session.get('UpdateVisitorId')});
}
now when i click button that redirects to another page and i need to print those values say name, phone number using the particular id of record which i could get from the above code.
my route code looks like this
Router.route('/print/:_id', {
name: 'print',
controller: 'PrintController',
action: 'action',
where: 'client'
});
and my print html is this
<template name="Print">
This is: {{VisitorName}}
Visiting:{{EmployeeName}}
Phone:{{PhoneNumber}}
how can i publish and subscribe and print those certain values of that id
Publish and subscribe can take arguments. You also want to use this.params to get the URL parameters. This is the general pattern
Router.route('/foo/:_id', {
name: 'foo',
waitOn: function(){
// this grabs the ID from the URL
var someId = this.params._id;
// this subscribes to myPublication while sending in the ID as a parameter to the publication function
return [
Meteor.subscribe('myPublication', someId)
]
}
});
/server/publications.js
Meteor.publish('myPublication', function(id){
check(id, String);
return MyCollection.findOne({_id: id});
});
You'll now have access to the data you subscribed to on this route.

I have the following code which returns the internal ID of a sales order by looking it up from a support case record.
So the order of events is:
A support case is received via email
The free text message body field contains a reference to a sales order transaction number. This is identified by the use of the number convention of 'SO1547878'
A workflow is triggered on case creation from the email case creation feature. The sales order number is extracted and stored in a custom field.
The internal ID of the record is looked up and written to the console (log debug) using the workflow action script below:
*#NApiVersion 2.x
*#NScriptType WorkflowActionScript
* #param {Object} context
define(["N/search", "N/record"], function (search, record) {
function onAction(context) {
var recordObj = context.newRecord;
var oc_number = recordObj.getValue({ fieldId: "custevent_case_creation" });
var s = search
.create({
type: "salesorder",
filters: [
search.createFilter({
name: "tranid",
operator: search.Operator.IS,
values: [oc_number],
}),
],
columns: ["internalid"],
})
.run()
.getRange({
start: 0,
end: 1,
});
log.debug("result set", s);
return s[0];
}
return {
onAction: onAction,
};
});
I am trying to return the resulting internal ID as a parameter so I can create a link to the record on the case record.
I'm getting stuck trying to work out how I would do this?
Is there a way to store the value on the case record, of the internal ID, that is looked up? (i.e.the one currently on the debug logs)?
I am very new to JS and Suitescript so am not sure at what point in this process, this value would need to be stored in the support case record.
At the moment. the workflow action script (which is the part of the workflow the above script relates to) is set to trigger after submit
Thanks
Edit: Thanks to Bknights, I have a solution that works.
The workflow:
The new revised script is as follows:
*#NApiVersion 2.x
*#NScriptType WorkflowActionScript
* #param {Object} context
*/
define(["N/search", "N/record"], function (search, record) {
function onAction(context) {
var recordObj = context.newRecord;
var oc_number = recordObj.getValue({ fieldId: "custevent_case_creation" });
var s = search
.create({
type: "salesorder",
filters: [
search.createFilter({
name: "tranid",
operator: search.Operator.IS,
values: [oc_number],
}),
],
columns: ["internalid"],
})
.run()
.getRange({
start: 0,
end: 1,
});
log.debug("result set", s[0].id);
return s[0].id;
}
return {
onAction: onAction,
};
});
On the script record for the workflow action script, set the type of return you expect. In this case, it would be a sales order record:
This would allow you to use a list/record field to store the value from the 'search message' workflow action created by the script
the result
Edit 2: A variation of this
/**
*#NApiVersion 2.x
*#NScriptType WorkflowActionScript
* #param {Object} context
*/
define(["N/search", "N/record"], function (search, record) {
function onAction(context) {
try {
var recordObj = context.newRecord;
var oc_number = recordObj.getValue({
fieldId: "custevent_case_creation",
});
var s = search
.create({
type: "salesorder",
filters: [
search.createFilter({
name: "tranid",
operator: search.Operator.IS,
values: [oc_number],
}),
],
columns: ["internalid","department"],
})
.run()
.getRange({
start: 0,
end: 1,
});
log.debug("result set", s[0]);
recordObj.setValue({fieldId:'custevent_case_sales_order', value:s[0].id});
// return s[0]
} catch (error) {
log.debug(
error.name,
"recordObjId: " +
recordObj.id +
", oc_number:" +
oc_number +
", message: " +
error.message
);
}
}
return {
onAction: onAction,
};
});
Depending on what you want to do with the order link you can do a couple of things.
If you want to reference the Sales Order record from the Support Case record you'd want to add a custom List/Record field to support cases that references transactions. (ex custevent_case_order)
Then move this script to a beforeSubmit UserEvent script and instead of returning extend it like:
recordObj.setValue({fieldId:'custevent_case_order', value:s[0].id});
For performance you'll probably want to test whether you are in a create/update event and that the custom order field is not yet filled in.
If this is part of a larger workflow you may still want to look up the Sales Order in the user event script and then start you workflow when that field has been populated.
If you want to keep the workflow intact your current code could return s[0].id to a workflow or workflow action custom field and then apply it to the case with a Set Field Value action.
I'm trying to return all groups that the current user is a part of. Each user has a groups field that's simply an array of id's for the groups the user belongs to. Here's what my code looks like:
My server method for returning the correct groups
userGroups: function(){
var currentUser = Meteor.users.find({_id: Meteor.userId()});
return Groups.find({_id: { $in: currentUser.groups}});
}
Then the call to that method in my helper:
groups: function(){
return Meteor.call('userGroups');
}
I've tried debugging this in the console but I'm just getting more confused. I can call var user = Meteor.users.find(_id: Meteor.userId()) and it correctly assigns the current user to the variable, but then when I call user.groups (which is the array of group id's) it says it's undefined. If I check the document in the meteor mongo command line interface, the current user has a groups field with group id's in it.
find query in Meteor returns a cursor which is not an array, but an object.
You should add .fetch() or use findOne().
userGroups: function(){
var currentUser = Meteor.users.findOne({_id: Meteor.userId()});
// or use var currentUser = Meteor.users.find({_id: Meteor.userId()}).fetch();
return Groups.find({_id: { $in: currentUser.groups}});
}
This should work!
Update on publishing groups form Meteor.users collection
To add groups from Meteor.users collection to your Meteor.user() auto-publish which acccounts-password package does, you need to include that into a null publication.
Something like this:
Meteor.publish(null, function () {
if (!this.userId) return this.ready();
return Meteor.users.find({_id: this.userId}, {
fields: {
profile : 1,
emails : 1,
groups : 1
}
});
});
i have an "back end" application which write in MongoDb (in database i have _id: with ObjectId("13f6ea...002")) i use meteor app to show information. Everything was good i displays list of information with {{#each}}. But when i wanted show one element with '_Id' nothing works.
I read this issue and adapt my code to get right root, But i can't display anything on the page. I tried to write Template helpers but it didn't helped
Db record:
{
_id: ObjectId("13f6ea...002"),
url: "foo",
title: "bar",
published: "2014-08-22 03:26:21 UTC",
image: "foo.jpg",
summary: "foo ",
categories: [
"F",
"B"
],
...
}
Route:
this.route('news', {
path: '/news/:_id',
template: 'news',
waitOn: function () {
var id = this._id;
Meteor.subscribe('news', id);
},
data: function() {
var id = this.params._id;
return News.findOne({ _id: Meteor.Collection.ObjectID(this.params._id)});
},
action : function () {this.render();},
});
Publish
Meteor.publish('news', function(id) {
return News.find({_id: id});
});
Template which redirect to unique post
<h4>{{title}}</h4>
And template is just {{news}}
How can i fix this?
UPDATE
My solutions to fix that:
router.js
waitOn: function () {
var id = this._id;
Meteor.subscribe('News', id);
},
data: function() {
return News.findOne(new Meteor.Collection.ObjectID(this.params._id));
},
and in template
<a href="news/{{_id._str}}">
Navigate to the appropriate url in your browser (i.e. localhost:3000/news/[_id]), open the console and enter:
Router.current().data()
That will show you the data context of the current route. Either it returns nothing, in which case there is a fundamental problem with your News.findOne query as it's returning nothing, or (more likely) it returns the required document.
In the latter case, as far as I can see there is no news property within that document, which is why it isn't rendering anything. If you change {{news}} to {{url}} or {{summary}} I would imagine it would render the requested property.
If by {{news}} you're trying to render the entire document, then (aside from the fact that it will render as something like [Object]) you need to make news a property of the object returned by your data function:
return {
news: News.findOne({ _id: Meteor.Collection.ObjectID(this.params._id)});
};
Getting Document with _id :
In the .js file under events, Say on click event and Collection EventList :-
'Submit form' : function () {
var id = this._id;
return EventList.find({_id : id}).fetch();
}
This would return the object for the id. In my Case, I am displaying a field for all documents in Collection. User selects a record and clicks Submit, which fetches all Document fields and displays to the User
Getting into sails.js - enjoying the cleanliness of models, routes, and the recent addition of associations. My dilemma:
I have Users, and Groups. There is a many-many relationship between the two.
var User = {
attributes: {
username: 'string',
groups: {
collection: 'group',
via: 'users'
}
}
};
module.exports = User;
...
var Group = {
attributes: {
name: 'string',
users: {
collection: 'user',
via: 'groups',
dominant: true
}
}
};
module.exports = Group;
I'm having difficulty understanding how I would save a user and it's associated groups.
Can I access the 'join table' directly?
From an ajax call, how should I be sending in the list of group ids to my controller?
If via REST URL, is this already accounted for in blueprint functions via update?
If so - what does the URL look like? /user/update/1?groups=1,2,3 ?
Is all of this just not supported yet? Any insight is helpful, thanks.
Documentation for these blueprints is forthcoming, but to link two records that have a many-to-many association, you can use the following REST url:
POST /user/[userId]/groups
where the body of the post is:
{id: [groupId]}
assuming that id is the primary key of the Group model. Starting with v0.10-rc5, you can also simultaneously create and a add a new group to a user by sending data about the new group in the POST body, without an id:
{name: 'myGroup'}
You can currently only add one linked entity at a time.
To add an entity programmatically, use the add method:
User.findOne(123).exec(function(err, user) {
if (err) {return res.serverError(err);}
// Add group with ID 1 to user with ID 123
user.groups.add(1);
// Add brand new group to user with ID 123
user.groups.add({name: 'myGroup'});
// Save the user, committing the additions
user.save(function(err, user) {
if (err) {return res.serverError(err);}
return res.json(user);
});
});
Just to answer your question about accessing the join tables directly,
Yes you can do that if you are using Model.query function. You need to check the namees of the join tables from DB itself. Not sure if it is recommended or not but I have found myself in such situations sometimes when it was unavoidable.
There have been times when the logic I was trying to implement involved a lot many queries and it was required to be executed as an atomic transaction.
In those case, I encapsulated all the DB logic in a stored function and executed that using Model.query
var myQuery = "select some_db_function(" + <param> + ")";
Model.query(myQuery, function(err, result){
if(err) return res.json(err);
else{
result = result.rows[0].some_db_function;
return res.json(result);
}
});
postgres has been a great help here due to json datatype which allowed me to pass params as JSON and also return values as JSON
I'm trying to load the latest post from a collection and at the same time all of the comments of that same post. The collection have references instead of storing the whole documents inside each other:
Post { title, body, etc..}
Comment { postId, body, etc.. }
I'm using iron-router as the routing package and in the route of my page I'm subscribing with this way:
this.route('home', {
path: '/',
template: 'home',
waitOn: function () {
return [
Meteor.subscribe('latestPost'),
Meteor.subscribe('lastReadPost')
];
}
});
The code that retrieves the post is simply:
Posts.findOne({}, {sort:{createdAt:-1, limit:1}});
Now the problem is that I don't know how to retrieve the comments without reading the whole collection. I can't subscribe in the router as I still do not have the post ID to query the Comments collection.
I guessed I could do that from the Template, but of course if I query the Comments collection, it's still empty. But I do have the postId as it's inside the Posts collection at that time. But I would need to trigger a subscription from the Template and that doesn't sound like a clean solution.
What would the best practice be? Thanks!
Server side code:
Meteor.publish("latestPost", function () {
var post = Posts.find({}, {sort:{created:-1}}).fetch()[0];
console.log("publish : " + post.title);
return [
Posts.find({_id: post._id}),
Comments.find({postId: post._id})
];
});
Client side code:
this.route('home', {
path: '/',
template: 'home',
waitOn: function () {
return [
Meteor.subscribe('latestPost')
];
},
data:function(){
return {
post:Posts.findOne(),
comments:Comments.find()
};
}
});
Check this repository to see whole example.
After user changes to another route, then subcriptions are being automatically stopped.
I would also include a limit in the server side finder options
{sort : {created : -1}, limit : 1}
