I'm not explicitly having a problem, but I would like an explanation. I understand the usefullness of dtml-with in dtml. I was converting some dtml methods to python scripts and I ran across a dtml-with. Is there an equivalent for python scripts? If so, great. If not, please explain why it is not needed. Thanks in advance.
"dtml-with" is a tool for putting names on the namespace stack, which is critical for DTML, since the namespace stack is the source of all names. Python, on the other hand, doesn't use DTML namespaces, although it can manipulate them like any other data structure. It doesn't need them, since it can easily create a local variable. Example: <dtml-with expr="foo.bar.controller()"><dtml-var x><dtml-var y></dtml-with> This really means "put 'foo.bar.controller()' on the namespace stack, ask the namespace stack for 'x' and 'y', then pop the stack, but the person who wrote it was probably thinking "get 'x' and 'y' from foo.bar.controller()". In this case, the following Python works: fbc = foo.bar.controller() print fbc.x print fbc.y Cheers, Evan @ digicool & 4-am
