[Zope-dev] Suggestion for DT_In

[Johan Carlsson]

Hi,
I found a small change that can solve a problem with
sort_expr in dtml-in.

There is no way to let the dtml-in not sort when
using sort_expr. This would be a good thing if you
want to be able to choose the default order of
the sequence:

A small patch to DT_In enables the dtml-in to
ignore sorting if the result of the expression is None.


         if self.sort_expr is not None:
             self.sort=self.sort_expr.eval(md)
-           sequence=self.sort_sequence(sequence, md)
-       elif self.sort is not None:
+       if self.sort is not None:
             sequence=self.sort_sequence(sequence, md)


This patch needs to be done in to places:
renderwb and renderwob as far as I can see.
