I have called the partial file form the loop. now when i update , i do not actually get updated result but need to do refresh for getting updated result. the code is like this :

the file1

  @folders.each do |@folder|
  = render :partial => 'folders/group_list'

the partial file

%div{:id => "group_list_#{@folder.id}"}  // this is the div which needs to be updated
  = group_member(@folder)   //this is the helper method

I need the updated @folder from controller but I always get file1's @folder

controller side

def any_method
  ..
  some code
  ..
  @folder = Folder.find(params[:folder_id])
  render :partial => '/folders/group_list'
end
