Hi,
I'm writing a custom change manipulator for a model. I'm not using
the default because there's some special processing that has to happen
on each save. Now, this model has a ManyToMany relationship. How do I
add a form field that will update that relationship? In effect, it has

Thanks. I think I figured it out. It's not the expr tag, it's {%%}. It
seems that {%%} doesn't cause a form field to render into HTML the way
{{}} does.

Hi Eugene,
Thanks for this example. I think it'll be helpful for me. I'm
working on something like this right now, where I need to generate a
whole bunch of small and simple subtemplates inside of a main layout

Malcolm and Adrian,
Thanks so much for your quick replies! I thought of that, but I
didn't know if it was the Djangoic way of doing it.
Follow up question -- are _all_ the files in the sql/ directory
executed, or just those that have the same names as the models?

Hi,
I'm trying to implement a complicated sequence of updates inside a
form-handling view, and I realized that it might be best to do it
inside a Postgresql function. In fact, I've already found sample code
for a postgres function that's almost exactly what I need.
My question is, how do I
I'm going to try to do the same thing as well. I have a vague idea that
I have to write a custom view for it, but I'm still trying to figure
out the right way to do it. Any pointers?
