I pass Member to the template with something like this...(I don't have
my code here with me)
VIEW
...
if not post
member = MemberModel(pk=1)
return render_to_response('mytemplate.html', {'Member':member})
Basically, I am providing a Member (ModelForm) to the template.
What you gave me here should help, I was not familiar with additional
parameters, I will
look more into that. I just thought I needed the posted data and it
would include the primary key
and then I could load that member again and pass to the save routine.
Thank you!
