Displaying a Carrierwave filename in the view

Question

I am trying to display the filename of a Carrierwave attachment in a Rails erb template. The following does not work:

<%= @page.form.filename %>
         


        

Answer 1

This is my solution:

  before_save :update_file_attributes


  def update_file_attributes
    if file.present? && file_changed? 
      self.content_type = file.file.content_type
      self.file_size = file.file.size
      self.file_name = read_attribute(:file)
    end
  end
