I read sometimes from people that seem to be working with rails since longer, that one important lesson they learnt would be “Don’t use scaffolding”. Also on irc I read commonly hints from this direction.
My question is why, what is the bad thing about it? And is nifty_scaffolding bad as well?

My guess would be it is bad because it generates by default an xml version of your controller action, which would expose the field names of our application to anybody and make it more vulnerable for attacks, so maybe it’s this?

What are your reasons to not do scaffolding?

    I’m experienced with rails and I rarely use scaffolding simply because my end goal is far from simple CRUD actions. However, there’s no strict rule to not use scaffolding. Some coders frown on it because it is actually scaffolding, literally. It’s not a finished product. Scaffolding supports you as you build the actual product. Search google images for “scaffolding” and you should get the idea.

    Keep in mind scaffold is just one of many built-in generators in Rails. A Rails generator is simply a script that outputs some generic code. Generators are very useful time-savers, and you’ll quickly find yourself writing generators for your own custom needs.
