Rails — create and create! methods, RoR 3 Tutorial

Question

So I know the distinction between the bang (exclamation mark) and non-bang methods usually is whether the method will modify the object itself or return a separate modified obje

Answer 1

Hope this helps as well:

The bang versions (e.g. save!) raise an exception if the record is invalid. The non-bang versions don’t: save and update_attributes return false, create and update just return the objects.
