meteor upload a file to mongodb

问题

I am trying to find a way to upload an mp3 file into a mongo collection through my meteor collection. Its a bit challenging as I end up with "C:\fakepath\audio.mp3" as what is saved in the collection.

Any help is greatly appreciated. Thanks.

You are looking for the FSCollection Package, and the GridFS Storage Adapter.

to get started run this on the console.

meteor add cfs:standard-packages

meteor add cfs:gridfs

now With fsCollection you can upload files simple as.

First

Declare the Collection.

AudioCollection = new FS.Collection("AudioCollection", {
  stores: [new FS.Store.GridFS("AudioCollection")]
});

Create a simple Event handler.

Template.example.events({
  'click #example':function(e,t){
    //Simple Event to upload files into mongo.
  }
})

And do a simple helper

Template.example.helpers({
 showAudio:function(){
   return AudioCollection.find();
  }
})

With this HTML

{{each showAudio}}
  {{#if isAudio}}
   <!-- show whatever you want here -->
  {{/if}}
{{/each}}

Since the README its empty at this moment i made a sample DEMO.
