I am trying to pass the value of a result from a child element to its parent element. Initially, I used Session.set and Session.get which worked fine but I realize that using Sessions globally is not considered good practice. So, I attempted to utilize reactive vars or reactive dicts instead, however, they only return an object as a result. How can I extract specific data from that object or what approach should I take? (I am storing JSON data inside the ReactiveVar or Dict and I am aware that it might not be ideal with JSON. Thank you for your assistance!
Template.companyCreate.helpers({
CompanyName : function () {
if (Meteor.user() || Roles.userIsInRole(Meteor.user(),['admin','adminCreator'], 'companyAdmin')) {
Meteor.call('findCompany', function(err, result) {
if (err) {
console.log(err.reason)
}
else {
// Will need to handle the result here and pass it to the parent function
}
});
return // Need to retrieve the result passed from the child function and return it for CompanyName
}
else {
Router.go('/nemate-prava')
}
},
UPDATED CODE
Template.companyCreate.onCreated(function Poruke() {
this.message = new ReactiveVar(' ');
let self = this;
let user = Meteor.user();
let companyNameHandler = Template.currentData().companyNameHandler;
self.companyName = new ReactiveVar();
if (user && Roles.userIsInRole(user,['admin','adminCreator'], 'companyAdmin')) {
Meteor.call('findCompany', function(err, result) {
if (err) {
console.log(err.reason)
}
else {
self.companyName.set(result);
companyNameHandler(result);
}
});
}
else {
Router.go('/nemate-prava')
}
});
Template.companyCreate.helpers({
message: () => { return Template.instance().message.get() },
isNotInRole : function() {
if (!Meteor.user() || !Roles.userIsInRole(Meteor.user(),['admin','adminCreator'], 'companyAdmin')) {
return true;
}
else {
return false;
}
},
CompanyName : function () {
return Template.instance().companyName.get();
}
});
Template.companyCreate.events({
'submit form': function(event, template) {
var Ime = event.target.Ime.value;
event.preventDefault();
Meteor.call('companyCheck', Ime, function(error, result) {
if (error) {
console.log(error.reason);
template.message.set(error.reason);
alert(error.reason);
}
else {
event.target.Ime.value = "";
console.log('Kompanija je uspesno kreirana!');
template.message.set("Uspesno!");
}
