From http://api.rubyonrails.org

Syntax: file_field(object_name, method, options = {})

You should be doing file_field :show, :upload to parameterize it
within the ‘show’ object.

Also, just use <%form_for @show, do |f| %> … <% end %> instead of
qualifying each tag. You can then use f.text_field :mobile_name,
f.field_field :upload ,etc.
