There is only a "." on line 7. How would that trigger a syntax error?

Thanks and regards,
Paul

Because a '.' on a line on its own is not a valid Ruby expression...

Dan

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

Shouldn't that have the normal methods in there instead?

Thanks,
Paul

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

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

OK, thanks for the explanation.

Paul
