Join For FreeFor assignment self is necessary. This clarifies that we assign an attribute and not a local variable.
class User < ActiveRecord::Base
def set_first_name_to_oliver
self.first_name = 'oliver'
end
end
For access self is not necessary and we should leave it away.
class User < ActiveRecord::Base
def full_name
"#{first_name} #{last_name}"
end
end
