I am encountering difficulties while trying to export a table to CSV in the Meteor/Blaze framework. I am following the guide on: [.
My Template.event is responsible for triggering the export button.
Template.export.onCreated( () => {
Template.instance().subscribe('table');
});
Template.export.helpers({
exportContacts() {
return Contacts.find();
}
});
Template.export.events({
'click .export-data' () {
MyAppExporter.exportAllContacts();
}
});
The exportAllContacts() function is called from a global helper.
MyAppExporter = {
exportAllContacts: function() {
var self = this;
Meteor.call("exportContacts", function(error, data) {
if ( error ) {
alert(error);
return false;
}
var csv = Papa.unparse(data);
self._downloadCSV(csv);
});
},
_downloadCSV: function(csv) {
var blob = new Blob([csv]);
var a = window.document.createElement("a");
a.href = window.URL.createObjectURL(blob, {type: "text/plain"});
a.download = "contacts.csv";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
}
}
The helper function calls a Meteor.method named exportContacts.
Meteor.methods({
exportContacts: function() {
let fields = [
"Email",
“Some Contact",
"Created Date",
"Hard Bounce",
"Unsubscribed"
];
let data = [];
let contacts = Contacts.find().fetch();
for(let i = 0; i < contacts.length; i++) {
let contact = contacts[i];
let contactString = JSON.stringify(contact);
_.each(contactString, function(c) {
console.log("Inside Loop", contactString);
data.push([
c.contact.emailAddress,
c.contact.someContact,
c.contact.creationDate,
c.contact.hardBounceBack,
c.contact.unsubscribed
]);
console.log("DATA", data)
return {fields: fields, data: data};
});
}
}
});
However, an error keeps occurring stating that “emailAddress is not defined exportContacts.js:20:17
20160426-22:00:47.957(-4)? Inside Loop {"_id":"dRnXRdZrbR9CYdmBx","contact":[{"emailAddress":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="abcdd9cecfebdccecad8c7d285c8c4c6">[email protected]</a>","someContact":"No","creationDate":"N/A","hardBounceBack":"N/A","unsubscribed":"N/A"}]}

I have been struggling to access the contacts despite logging them out (as seen in the logs above). Any assistance would be greatly appreciated.
