Jesus Christ, why would you want to use ZODB as a backend if you'renot using Zope? The mind boggles ;)The closest thing I have seen is my own Django-Zope bridge, but thatis more for pulling HTML generated by Django into a Zope-driveninterface, and does not deal with the ZODB directly in any way.If you can elaborate on what you want to accomplish that may help uspoint you in the right direction.Regards,
Jeff

This has never been tried, to my knowledge. It would be possible --
and relatively easy -- to do if there were a DB-API-compliant ZODB
library. Is there one? I know nothing about ZODB, other than the fact
that it's associated with Zope. I think.

ZODB is an object database, not a relational one; based on my
experience with it and other object DBs, it's not a good fit for the
MVC-like separation Django adheres to.

I am curious to learn more about why "object DBs are not good fit forthe MVC-like separation". Previously I had very basic exposure toZODB, along with the concept of object database, when I played withZope a bit years ago.Thanks.

ZODB Anyone ?


Greeting everyone...Yes, i'd be curious too! I see MVC and OODB/SQLDB as completelyorthogonal concepts.Plus, if I may add, the distinction between OODB and relational can inpractice not always be so clear. In fact I know of two efforts that tryto combine the benefits of both these worlds, i.e of combining realobjects with a "tabular" organization.One of these is the moellus package, that is a layer on top of thesmall Durus OODB (that is a ZODB-inspired OODB, but intentionallysimpler), that organizes items (objects) in containers (tables). Thepackage allows you to define an object model, similar to an ORM.However, you can think of this as an ORM without the mapping layer, asyour model *is* your database. Other advantages you get for free arereal object references, as well as typically difficult-to-have featuressuch as "mutable compound primary keys". Moellus is at:<http://ruggier.org/software/moellus/>The other one I know of is Schevo from Orbtech. There may well beothers, but my point is which back-end you use has, or should have,nothing to do with how you organize your user application.mario
