EasyNils¶ ↑

Why write this

user && user.account && user.account.authorized?

when what you want is this

user.account.authorized?

EasyNils lets you abridge compound conditional expressions returning nil if any of the method calls return nil.

Install

• sudo gem install easy_nils

Use

• require ‘easy_nils’

Rails

• gem.config ‘easy_nils’

If you need to explicitly test for a nil value, then do so

if user.account.authorized?
  ... do something for an authorized account
elsif user.nil? || user.account.nil?
  ... do something here for the nil case
else
  ... do someting for an unauthorized account
end
