i am getting this same exact error message when i try to do a
User.find_by_username('array'). Im have twitter users signed up on my
site and i am trying to find the the users on my site from a
timeline.

When i try <%= User.find_by_username('status.user.screen_name') %> It
returns nil, but if i use <%= status.user.screen_name %> it returns
all the user screen names so i can not figure out what is going wrong.
