Django, save data from form without having to manually set each field to save ?

Question

I can't seem to figure out a good way to do this,

I have a bunch of form input fields and rather than having to do like below where I have to type out each fieldname = "" and such, is there a way to code this so it would automatically save each field from within the form?

b = Modelname(fieldname=request.POST['fieldname'])
b.save()

I realize security issues of this but could be negated by running it through a list that checks for a valid form value.

Sure, request.POST.items() and request.POST.iteritems() work just like the methods of the same name in a dict, returning resp. a list and an iterator of all (name, value) pairs (2-items tuple) in that dict-like object. If there are multiple values for a name, that only gives you the last one; if you want all of them, use request.POST.iterlists(), which in the value slot of each pair has a list of all the values for fields with that name.

So, assuming for example that you don't care about duplicates or know there are none, even a snippet as short as:

for name, value in request.POST.iteritems():
    ModelName(**dict( [ (name, value) ] )).save()

might suffice, though it might definitely be better to add some validation checking of the name/value pair before saving it this way;-).
