Thanks for replies. This:
post.blog_images.first.image_file_name outputs undefined method `image_file_name' for nil:NilClass I think that means I called a method on a class that it cannot find? I have already established has_many belongs_to between blog_images and posts table. This doesn't return error but doesn't output anything: post.blog_images.map(&:image_file_name) Although there are values in the image_file_name field of blog_images table. And if I was to hard code that value in url, it would work, so that map isn't doing what's expected of it. ANy suggestions? thanks for response. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
