9 years ago Try this example
if (Meteor.isServer) {
Meteor.publish('jobCompleted', function() {
Counts.publish(this, 'numJobCompleted', myJobs.find({status: {$eq: "completed"}}));
});
Meteor.publish('atDNA', function() {
Counts.publish(this, 'numAtDNA', Gedmatches.find({ atTotalCm: {$exists:true} }));
});
}
if (Meteor.isClient) {
Meteor.subscribe('jobCompleted', function () {
console.log('Number of jobs completed (client): ', Counts.get('numJobCompleted'));
});
Meteor.subscribe('atDNA', function () {
console.log('Number of atDNA matches (client): ', Counts.get('numAtDNA'));
});
}Do you still get zero for both?
If not, then I think you fell victim to asynchronicity. IIRC, Meteor.subscribe will return immediately and the data/counts will find their way to the browser reactively, but while that's happening your example immediate prints the counts before they've been reactively updated. Since console.log isn't reactive, you only ever see the very first counts of zero. The example above uses a callback to wait until the subscription is ready before fetching the counts.
If I'm right on this, you might try another example that is reactive.
if (Meteor.isClient) {
Meteor.subscribe('jobCompleted');
Meteor.subscribe('atDNA');
Tracker.autorun(function () {
console.log('Number of jobs completed (client): ', Counts.get('numJobCompleted'));
});
Tracker.autorun(function () {
console.log('Number of atDNA matches (client): ', Counts.get('numAtDNA'));
});
}

Autopublish package is removed. Here's the code in counts.html:
Output in the browser console is:
Number of jobs completed (client): 0 Number of atDNA matches (client): 0
Whereas the same query:
executed on the server (and in Mongodb shell) gives:
Number of jobs completed (server): 207 Number of atDNA matches (server): 51
I'm not sure what I'm doing wrong, tried to copy everything from the documentation. FYI - A normal find with a pub for all records (without further filter) find all records and works.
Thanks in advance for your help!
