[Zope] SQL trees...

[Mayers, Philip J]

Excellent. That answers that.

I'm loath to ask this, since it's supposedly a FAQ, but I'm having trouble
with the tree...

Following:

http://www.zope.org/Members/anthony/tree-coding-tricks

I've got:

<dtml-let network="'0/0'">
<dtml-tree id=network branches_expr="network_children(parentnet=network)">
 <b><dtml-var network></b> <dtml-var descr>
</dtml-tree>
</dtml-let>

The SQL query is working - "test"ing network_children will give the correct
hierarchy. However, the tree generated looks like this:

192.168/16
  192.168/16
    192.168/16
    10/8
    172.20/16
  10/8
    192.168/16
    10/8
    172.20/16
  172.20/16
    192.168/16
    10/8
    172.20/16
10/8
  <etc>

Basically, the tree only seems to ever contain the top-level (children of
the root of the tree).  The children of all the nodes is... another copy of
the root top-level nodes! Whu?!? A search for several variations of "SQL
tree" in all the relevant list/site archives didn't seem to help. Any ideas?

Regards,
Phil

Anything in a DTML tag that's inside "" is python, usually ;-)

So, your dtml-let should be:
<dtml-let network="'0/0'">

which is kinda yucky, don't you think?

cheers,

Chris
