Nested attributes using paperclip rails 4

What's in your deal_param method?
Do you permit deal_photos' attributes in it?
If no then do something like

def deal_params
 params.require(:deal).permit(deal_attr1, deal_attr2,...., deal_photos_attributes: [:deal_photo_attr1, ...])
end

Also, do you get a deal_id in your deal_photos in view?

How to use link_to inside a nested form in Rails?

I think you should be able to do

f.object.url

So:

%fieldset
  .field
    = f.label :file
    = f.file_field :file
    # Not sure if it would produce a Nil error on the new form.
    # given how the f object wouldn't yet have a url
    - if f.object.url
       = link_to f.object.url 
  .field
    = f.hidden_field :_destroy
    = link_to "Remove File", '#', class: "remove_fields"

Rails 4 nested form image preview with Paperclip

I'm not sure if this is the problem, but you shouldn't have multiple HTML elements with identical IDs. Try changing the JS so that it uses the class of file fields instead.

$(function() {
  $('.fileBt').on('change', function(event) {
...

Note that you probably want to rename that class to something more meaningful and specific to image upload fields. For example ".photo-upload-field" would work :)
