I want to override DTMLFile from Globals in my own special product. I managed to do this::
class PeterDTMLFile(DTMLFile): def foo(self): return "works"
I have not tried it in Zope, but it seems to me that you ought be be able to create new class methods just by assignment to the class (outside of the class definition). This works with normal Python classes, but I do not know how far a DTMLFile class differs from a normal class, nor how restricted product code might be compared with normal Python code.
Here is an example -
class Class1: pass
def foo(self): print 'This is "foo"'
Class1.foo = foo
obj = Class1() obj.foo() # prints This is "foo"
Of course, this would affect all instances of DTMLFile and I am not clear if you really intend that or not.
No that would be a hotfix on all instances of the DTMLFile class. Not what I was after. BTW, I've found my solution, but I guess I'll really need to inspect the code to sort out the security stuff. Will come back to the list for that probably. Peter
