Django имеет встроенный UpdateView. 

from django.views.generic.edit import UpdateView

class MyUpdateView(UpdateView):
    model = MyModel
    fields = ["field_1", "field_2"] # or use form_class = MyForm
    template_name = "myapp/mymodel_update.html"

Вам понадобится PK в вашем URL для просмотра обновлений, чтобы он мог правильно искать экземпляр модели (вы можете переопределить это установив lookup_url_kwarg в классе IIR C)
