Per method exception and ensure handlers
2006-04-17
In Ruby, methods automatically define begin/end blocks. That makes it easy to write exception handlers and ensure blocks:
1 def access!(options={})
2 raise AuthorizationFailure if self.email != options[:email]
3 self.download_count += 1
4
5 rescue AuthorizationFailure
6 self.unauthorized_access_count += 1
7 raise
8
9 ensure
10 self.save!
11 end
It is important to re-raise the exception in the exception handler, or else the exception will be silently thrown away.
