It's true for every language you don't know well. No one writes bug free Java code from scratch after few months of experience.

Also, even if you're right, it's not that bad, as it sounds. It's not possible to write something good at a first try. Code, like wine, takes time. A language that fools you to think otherwise makes your work harder.

I think the whole problem with Rails is the premise that you can create whole sites in a minute or two, literally without any significant experience.
