meteor collection fs forbid upload

Question

i want to forbid the upload / storage of files under special circumstances.

I tried in the collectionfs before hook:

Attachments.files.before.insert((userId, doc) => {
  if(!Meteor.isServer){
    if (!isUploadAllowed()) {
      throw new Meteor.Error('Upload not allowed');
    }
  }
}

Unfortunately this is not working.

Is there a better way to achieve this? Or can someone help me?

(An ugly solution would be to remove the uploaded document in the after.insert hook, i hope there is a better way)

Answer 1

You can set the deny for this collection for all client operations to false:

const Attachments.files = new Mongo.Collection('fs.files')
Attachments.files.deny({
  insert () { return true },
  update () { return true },
  remove () { return true }
})

This defaults to deny any client operation to sync with the server.
