If the object to which you delegate can be nil, you may want to use the :allow_nil option. In that case, it returns nil instead of raising a NoMethodError exception.
The main purpose of #devguru is to provide the best tutorials, tips and hacks that are connected with our work and passion, which is web developing.
Everyday we learn something new. We read articles, we solve problems that we deal with at work. We want to share our experience, knowledge, and the stuff we find on web and we find interesting.
If you want to contribute, find us on Flaker.pl or Facebook, send us a link and if we like it - you'll certainly find it here.
