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.
I am sure you don't want to hear this, but that's what '? = &' are for. If
you really want to make your life complicated you could look into storing
the parameters in cookies or session data, but those are pretty ugly
work-arounds just so you can have pretty urls.
