问题 I just started a new development server for a website I am working on and I can't seem to get the Django development server to serve the static files I have for CSS and other things. The CSS for the admin site loads fine. I am running it in a virtualenv sandbox. In settings.py I've messed around with MEDIA_ROOT and MEDIA_URL. So far for MEDIA_ROOT I've tried. MEDIA_ROOT = '/home/wluw/wluw/wluw/media' and MEDIA_ROOT = os.path.join(os.path.dirname(__file__), 'media') I changed my ADMIN_MEDIA

问题 Python/Django n00b moving over from javascript. Trying to add an API endpoint using Django REST Framework which I'm hoping will ultimately be able to update a User with the body of a PATCH request, but for now I just want it to not throw a 500 error.

I know thats because the HttpResponseRedirect. How can I change this without to break the form? views.py class cloud(CreateView): template_name = 'base/cloud.html' form_class = UserForm def get_context_data(self, *
