Checking if a field is read-only
210080 [ ni@ar bs ro] Can you help me please and tell how can i check if a field is read only
210081 [farrel.lifso] You could check to see if the object responds to "field=".

Call functions of superclass
210128 [bart.braem@g] I'd like to be able to do

| | + 210146 [wccrawford@g] He has redefined the 'another' method in the child class. But for some
| | | 210220 [listbox@ju i] I am not saying I _need_ to do that, I was curious if it's at all
| | + 210151 [jan.svitok@g] The OP defined method zoo in Child as well, and wanted to call the
| | + 210188 [nsmith5@um c] class Child < Parent
| | 210190 [dblack@wo bl] But the Parent class has no hoo instance method, so calling super from

| | 210219 [nsmith5@um c] If I'm thinking correctly, self.class.superclass will point to the
| | 210222 [dblack@wo bl] No; it will point to the superclass of the class of self :-)
| | 210327 [nsmith5@um c] class A
| | + 210328 [decoux@mo lo] no, not really. self.class.superclass make reference to the superclass of

| | | | + 210341 [decoux@mo lo] Re read carefully "Programming Ruby", it was written by someone which know
| | | | | 210342 [nsmith5@um c] Rather than making rash statements such as that, it'd be nice of you to

| | | | + 210457 [hal9000@hy e] Does the 2nd edition say that??
| | | | + 210532 [decoux@mo lo] Well the 2nd edition speak about the metaclass and there is a paragraph in
