局部视图和父视图Ruby on Rails之间的数据

Question

So I have a new.html.erb which contains the form for a new ad. This view renders a partial to upload images called _upload_control.html.erb. It contains <%= file_field_tag :fileupload %> and I'm trying to reference the uploaded in new.html.erb in order to get the file in the parent's controller. Is there a way to do this?

As per your comment

The partial i'm rendering in the form is used to upload multiple files for a different object, so its not using 'f'

You should use f(form builder) and need to pass your form builder in locals so that your partial can be called with that particular form builder, something like:

<%= form_for resource1 do |f|  %>
  <%=  render :partial => 'upload_control', :locals => { :f => f }  %>
<% end %>

<%= form_for resource2 do |builder|  %>
  <%=  render :partial => 'upload_control', :locals => { :builder => f }  %>
<% end %>

and your partial _upload_control.html.erb

<%= f.file_field :fileupload %>
