blank?()Link

nil is blank:

nil.blank? # => true

@return [true]

to_param()Link

Returns self.

try(*)Link

Calling try on nil always returns nil. It becomes especially helpful when navigating through associations that may return nil.

nil.try(:name) # => nil

Without try

@person && @person.children.any? && @person.children.first.name

With try

@person.try(:children).try(:first).try(:name)

try!(*)Link

Calling try! on nil always returns nil.

nil.try!(:name) # => nil
