[Zope] Passing context from DTML to Python

[Dylan Reinhardt]

There's hardly anything to do, really.  Context is passed for you.

If you have method A and script B in your root, a URL of the form:

http://yourserver/path/to/subfolder/A

will call A *in the context* of the path you specified.*  If A calls B,
then B will have the same context by default.  Ta da!

The fact that B is stored in the same folder as A is only relevant to
how A *finds* B, not to what context B runs in. For more detail, see the
Acquisition chapter of the Zope Book:
http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition

HTH,

Dylan


{*} - Assuming, of course, that there is no other object called A that
would be acquired first.  :-)
