I didn''t look at the code but it appears you are trying to iterate over an empty string. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

As it turns out, I had declared that my main object class had many of
another type of object (photos). In my object controller new method I
had
@object.photos.build
But then in my form I only had one field for the photo object. It was
trying to build the photo objects with just one string as input and
that is what was giving the method ''each'' error for String.
