How to use initialize FormModel with request.post and model instance.

So I basically have this code:

@render_to('hello/home.html')
def home(request):
    info = Info.objects.get(pk=1)
    if request.method == "POST":
        form = InfoForm(request.POST, instance=info)
    else:
         form = InfoForm(instance=info)
   return {"info": info, "form": form}

aaand it doesn't work as I guessed it would be. If I initialize form with ONLY either model instance or POST, it works, but not when both. Is there a (nice?) way to create form with data populated from model instance, and update it with data from request.POST?

The code you are writing is already in the framework.

urls.py

from django.views.generic import UpdateView
from myapp.forms import InfoForm
urlpatterns = patterns('',
    url(r'^info/(?P<pk>[-_\w]+)/update/$', UpdateView.as_view(model= Info,template_name="hello/home.html",form_class=InfoForm), name='info_update'), 
)
# you might need to include a success url in the **kwargs i.e. success_url="/thankyou/"
