Question

my form is

class MapForm(forms.ModelForm):
     class Meta:
        model = Map
        fields = ('mapName', 'kmlStr')

and the view is :

map_form = MapForm(request.POST or None)
if map_form.is_valid():
    map = map_form.save(commit=False)
    map.mapName=map_form.mapName#is this code right ?

how to get the mapName ‘s value , us ‘map_form.mapName’ ?

thanks

Not quite, you want to access the form fields through cleaned_data

Processing the data from a form

Once is_valid() returns True, you can
process the form submission safe in
the knowledge that it conforms to the
validation rules defined by your form.
While you could access request.POST
directly at this point, it is better
to access form.cleaned_data. This data
has not only been validated but will
also be converted in to the relevant
Python types for you. In the above
example, cc_myself will be a boolean
value. Likewise, fields such as
IntegerField and FloatField convert
values to a Python int and float
respectively.

map.mapName = map_form.cleaned_data['mapName']

However, you’re already using model forms, so you can save the form to return an object.

map_form = MapForm(request.POST or None)
if map_form.is_valid():
    map = map_form.save()
