Q:

Multi file uploads in rails 4

I'm having a few problems with multi file uploads in rails 4, I've got it working using carrierwave and polymorphic associations but its creating a file filed for every image in the view.  This makes sense as its creating fields for the associated model. 
If there is a better or more standard way of doing this in rails 4 I'd be grateful for your advise. 
Here is a gist to what I'm doing: https://gist.github.com/lperry65/5805b5f41495f8a820b7

There seems to be lots of ways to accomplish this, but most of the info I found while googling is for rails 3.  It's my intention to use UploadiFive for the front end once I iron out the wrinkles.

A:

Changing   <%= f.fields_for :images do |i| %> to <%= f.fields_for :images[0] do |i| %> stopped the file input from being duplicated for every image.  I can't say I'm happy with it but it works for now. 
I'll update the gist to reflect any other changes, it's all working now so I'll leave it until I find a better solution.
