'QuerySet' object has no attribute '_meta'

[ayayalar]

I am just simply trying to display all existing objects in a form

MODEL:
class Product(models.Model):
name = models.CharField(max_length=30)

def __unicode__(self):
return self.name

VIEW
def product(request):
product = Product.objects.all()
form = ProductForm(instance=product)
return render_to_response('index.html', {'form' : form})


Throws this error:

Any suggestions?

You don't show us ProductForm but I can guess it is a ModelForm for Product.  A ModelForm is designed to display and let you edit one individual object from the DB, not multiple.  Thus the 'instance' parameter to a model form is supposed to be one single instance of a model, not a QuerySet.  A model formset might be closer to what you are looking for:

Karen,

On this note, is it possible to customize the widget's for formsets as
well?


Thank you.

You can pass modelformset_factory a kwarg form which should just me
the form class you want to use(aka make a ModelForm with the changes
to the widgets).
