CollectionFS support

[ccorcos]

Would it be possible to add support for hooks on CollectionFS?

[matb33]

Interesting idea! I assume it's easy enough, probably just a matter of doing CollectionHooks.wrapCollection(FS.Collection, FS.Collection); and having the right api.use in package.js.

Here's an app you can test it with.

After some digging, the Meteor/Mongo.collection resides in the files property of the FS.Collection. So something like this should be working.

Pictures = new FS.Collection('pictures', ...);
Pictures.files.before.insert(function(userId, picture){...});

@fpoirier1 You rock! Thanks!

Still a quirk:

I've tried offloading some client work onto the server:

      # This now happens in the .before.insert hook
      # img.metadata =  
      #   date: Date.now()
      #   ownerId: Meteor.userId()

      Images.insert img,  (err, fileObj) ->
        if err
          console.log err

On the server, I try to take care of it:

  Images.files.before.insert (userId, doc) ->
    doc.metadata =  
      date: Date.now()
      ownerId: userId
    console.log "before", doc
    return doc

And I'm checking for the metadata here:

Images.allow
  insert: (userId, doc) ->
    console.log "insert", doc
    doc.metadata?.ownerId is userId

Based on the console log statements, when I insert an image, this is what happens:

The insert gets called twice and the before happens in the middle...

I wrote some tests in v0.7.9 to verify that hooks work with CollectionFS. I'm not getting any double inserts... I do get several update before/after hooks firing but that makes sense since CollectionFS updates properties as the file uploads.

@ccorcos are you still experiencing any issues? I'm not sure what to do at this point since my tests are passing... if you've resolved your issue I would be able to close this one off
