Daniel, In that case, isn’t the code on Listing 2.2, 2.3, 2.4 wrong here at [http://railstutorial.org/chapters/a-demo-app#top](http://railstutorial.org/chapters/a-demo-app#top) Shouldn’t that have the normal methods in there instead? Thanks, Paul ---

There is only a “.” on line 7. How would that trigger a syntax error? Thanks and regards, Paul ---

Paul, It looks like at some point when you started copy-pasting examples you got tired and stopped paying attention to explanations. Have a some rest, man. Dots alone are not a valid Ruby expression for sure. It’s all Ruby out there and has to comply. - A ---

Heheh! No, there’s nothing wrong there - the ‘.’ characters are simply placeholders for your own code. As your app grows, you’ll add more routes to routes.rb, and they will go where the dots are in the example listing. The same applies with the other listings - you need to fill out the method bodies with your own code, the exact nature of which will, of course, depend upon what your app needs to do. Try removing those pesky full stops and have another go. Dan ---

OK, thanks for the explanation. Paul
