I am trying to allow a user to edit their profile. In the post method I want to save the new data over the old data in the same row.
# Post method of class view in views.py
def post(self, request, username):
try:
user = User.objects.get(username=username)
except User.DoesNotExist:
raise Http404('The User "' + username + '" could not be found.')
if (not request.user.is_authenticated):
return HttpResponseForbidden()
elif (user.id is not request.user.id):
return HttpResponseForbidden()
form = self.form_class(request.POST)
if (form.is_valid()):
# creates a new user object, does not save to the database yet
profile = form.save(commit=False)
# clean (normalized) data
# ...
profile.save()
if (user.is_active):
return redirect('/profile/' + user.username)
return render(request, self.template_name, {'form': form, 'error_message': 'Oops, something went wrong'})
This code I believe is creating a new database row when the post method is called. How do I get it to update the existing row in a clean looking solution?
如果您使用Django的UpdateView
则它将保存ModelForm ..来处理许多这些详细信息。包括保存更新,成功重定向用户以及在出现问题时显示错误时重新显示表单。
