Module for mod_python

[rieh25]

Thanks for your response. Actually I have looked at some of them, although
not in great detail and haven't actually installed them. I do have to do
some more investigating, but I think I can say something right now. The one
thing I think I have to offer in terms of originality is the idea of keeping
state of record selection, and making that selection affect (filter) the
listing of related tables.

As an example this is the way a master-detail application for a chain of
book stores works normally: There is a detail form with a list of stores,
and upon selection of one of them, the id of the store is passed as a
parameter to a new page which lists the books in that store.

In my version, there is also a detail form with a list of the stores, but
the store id is not passed as a parameter, it is saved as a session
variable. Upon loading the page with the list of books, a filter takes
effect taking into accoung the store id. The saving of the session variable
and the filtering is never specified though. It is done automatically given
the existence of a foreign key in the books table making reference to a
store id.

As far as I know, db object relational mapper systems take care of the
creation of the tables in the actual database, and are capable of generating
forms given a table name, but my system would also take care of the
selection of records, and the cascading effect that has on related tables in
the sense of how they are listed in detail forms with corresponding filters.
I'm not sure that it is that new of an idea, or that helpful from someone
else's point of view, but it is something that I have put into practice and
have a good concept of it.

And I do recognize I should do more investigating...
