Hi Peter. This is very interesting. I will look at the code! I agree
with you about exposing the zsql methods and also I tend to use a
naming convention for zsql methods might even stick out more. Many
thanks for your reply.
Regards,
David

I have never used traversal into zsql methods simply because I don't
want to expose geeky things like "employee_by_id" to the user. People
should be able to find out what you call your ZSQL methods. My
suggestion is to consider a more controlled solution.
About having request variables in the URL I suggest you download and
study the code of the IssueTrackerProduct. Look for a method called
get_environ and __before_bobobase_traverse__
Then one gets URLs like this:
http://demo.issuetrackerproduct.com/ListIssues/sortorder-urgency/
reverse-true
which is translated in get_environ() to
http://demo.issuetrackerproduct.com/
ListIssues?sortorder=urgency&reverse=true

I have gone over the zope book to see what I can do about calling a
sql
with a form and getting three additional parameters in the request and
am wanting this to get better looking urls that calling the parameters
directly in the url. I asked a similar question yesterday but perhaps
it was not clear enough about what asking. It is really a traversal
question and how to string together a sql query with a zpt form that
also requires parameters from the request namespace.
I can call my zsql method and then my edit form like this:
/employee_by_id/employee_id/42/employee_edit_form
or with simple direct traversal on the zsql method:
/employee_by_id/42/employee_edit_form
Problem is I need three other parameters in the request for my edit
form to satisfy my sorting so when the edit form returns it is back on
the same batch page
Parameters passed in traversal go into the request namespace according
to the zope book so was hoping for something similar to this which
doesn't work - and I can't see how it could.
/employee_by_id/employee_id/42/employee_edit_form/start/2/sort/
employee/reverse/0
The zope book examples are with python scripts so am not sure whether
this is possible with a ZPT that also requires parameters from the
request or will I need a script to be called in the path somewhere to
pick up the results of the query and then pass parameters to the form
-
something like:
/employee_by_id/employee_id/42/some_other_script/start/2/sort/
employee/
reverse/0/employee_edit_form
where some_other_script would be a script python. Any hints to help
me
understand what can be done with traversal like this would be
appreciated since I would rather have nice urls instead of stringing
parameters directly in the url with all the ?= and &'s.

David
