undefined method `merge’ for 5:Fixnum – Hidden Field

Just a quick post on an error I ran into today while using hidden fields:

undefined method `merge' for 5:Fixnum

27:   
28: 'button' %> 29:
30: 31: 32:

Thankfully this is an easy fix, simply amend your code as follows:

'button' %>
@upload.product_id %>

And that’s all there is to it, let me know if there are any issues.
