Meteor-files: Aggregation

[bevinhex]

I wanted to get random files , but skip does not seem very effecient, So tried to install meteorhacks:aggregate, it seems to be working fine for Mongo.Collection, but not for FileCollection, when I tried to use .aggregate function on the file collection, it gives me
Uncaught TypeError: Images.aggregate is not a function error
Can Meteor-Files support aggregation operation? Mongodb is supporting it from version 3, Thanks.

Use Images.collection, read more about direct collection usage here

[bevinhex]

Tried that, calling Images.collection.aggregate() give error
Uncaught TypeError: Images.collection.aggregate is not a function
Below is the code for the method

Meteor.methods({
getRandomSelfies:function(size){
    return Images.collection.aggregate({$sample:{size:size}})
  }
})

Make sure you're on Server as meteorhacks:aggregate is server only package

[bevinhex]

The mothod above should be server side I believe
On client side I'm using Meteor.call('getRandomSelfies',2500) for calling that method
Images.find() method works fine and returns all records, I used skip() for achieving same effect, but think aggregate is more effecient.

Right, what on server-side you're getting from?:

console.log(Images.collection);
console.log(Images.collection.aggregate)

Have you tried to call .aggregate() on other default Mongo.Collection?
Like Meteor.users.aggregate()? To make sure meteorhacks:aggregate is working?

[bevinhex]

Okay, let me try

Ah my bad, it was not working for other Collections now, somehow I broke something, meteorhacks:aggregate not working correctly. I'll post how I did after I was able to use aggregate with FileCollection.
Thanks you very much :)

On server side calling Images.collection.aggregate({$sample:{size:1000}}); worked perfectly! Confirmed, meteorhacks:aggregate works nicely with Meteor-Files collection.

Can close this now.

Hi @bevinhex I'm glad it's solved. The one thing I was afraid of meteorhacks:aggregate - it's stale project with last commit more than 2 years ago. Thank you for testing this out.
