blank?()

nil is blank:

nil.blank? # => true

@return [true]

# File activesupport/lib/active_support/core_ext/object/blank.rb, line 56
def blank?
  true
end
to_param()

Returns self.

# File activesupport/lib/active_support/core_ext/object/to_query.rb, line 20
def to_param
  self
end
try(_method_name = nil, *, **)

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)
# File activesupport/lib/active_support/core_ext/object/try.rb, line 146
def try(_method_name = nil, *, **)
  nil
end
try!(_method_name = nil, *, **)

Calling try! on nil always returns nil.

nil.try!(:name) # => nil
# File activesupport/lib/active_support/core_ext/object/try.rb, line 153
def try!(_method_name = nil, *, **)
  nil
end
