Trying to learn Ruby on Rails is difficult enough when one doesn’t have a high level programming language background. Add that to running 6 miles before you get home and you have a recipe for the most common of errors, human.

I was working through the RailsSpace book last night and was in the section where I learn about sessions. I made a pretty common mistake. There is a section of the code the says after you save the user to the database you can set the user session. The code roughly looks like this session[:user_id] = @user.id. Well, I had wrote the code as follows session[:user_id] = @user_id. Notice the little underscore instead of the period. It took me over 30 minutes and 3 reference books to figure out what was going on.

Now, I know that no one out there has ever done anything like this. Have you? Post your reply to the comments.
