ActiveRecord object attribute name same as method name

Question

I'm trying to call a method on an ActiveRecord object where there is an attribute of the same name. This results in a SystemStackError: stack level too deep error.

How can I access the object attribute from within the method in order to modify it?

def first_name

 return self.first_name.upper

end

You could probably also do super.upper

If this is an Active Record model you can use read_attribute method

def first_name
  read_attribute(:first_name).upper
end
