Serving statics while on FORCE_SCRIPT_NAME
I'm struggling with serving static files while using apache2 proxy. I want to keep my django server on foo path like below. <VirtualHost *:80> ProxyPreserveHost On ProxyPass /foo/ http://0.0.0.0:8000/ ProxyPassReverse /foo/ http://0.0.0.0:8000/ </VirtualHost> With this settings my application is not getting static files e.g. admin site. My app doesn't throw any errors but in my browser i got: Failed to load resource: the server responded with a status of 404 (Not Found) I tried to proxy static <VirtualHost *:80> ProxyPreserveHost On ProxyPass /foo/ http://0.0.0.0:8000/ ProxyPassReverse /foo/ http://0.0.0.0:8000/ ProxyPass /static/ http://0.0.0.0:8000/static/ ProxyPassReverse /static/ http://0.0.0.0:8000/static/ </VirtualHost> And now all I get is: [16/Dec/2021 10:54:14] "GET /api/ HTTP/1.1" 200 5763 [16/Dec/2021 10:54:14] "GET /static/rest_framework/css/bootstrap.min.css HTTP/1.1" 404 1949 [16/Dec/2021 10:54:14] "GET /static/rest_framework/css/bootstrap-tweaks.css HTTP/1.1" 404 1958 [16/Dec/2021 10:54:14] "GET /static/rest_framework/js/jquery-3.5.1.min.js HTTP/1.1" 404 1952 I ran python manage.py collectstatic and my settings.py are: DEBUG = True STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' FORCE_SCRIPT_NAME = '/foo' If I leave my proxy on / everything works fine.

django rest_framework login system [closed]
I'm using Django and djangorestframework library to make a simple login system in which I get an authentication token if everything is right, but when I'm testing it with Postman, it only accepts the credential when they are in the body section. My questions are: Is this the right thing to send these pieces of information in the body section? If not, how can I change Django to accept these fields in the header section? Also where should I put the authentication token for future uses? (Header or Body) Thank you in advance. -

install multiple apps by one entry in INSTALLED_APPS in django (dependency)
is the concept of dependencies available in Django apps too? For example, let's say I'm building my own custom Django app "polls" that can be reused in any Django project. so whenever you need to add it to a project, you will have to add INSTALLED_APPS = [ ... 'polls.apps.PollsConfig', ] but let's also say, that this polls app depends on the Django REST Framework, so whenever you use it, you will have to add that as well INSTALLED_APPS = [ ... 'polls.apps.PollsConfig', 'rest_framework', ] And how about if it depends on even way more apps, do I have to list them all again in the settings.py of each and every project? Or, is there some way to add rest_framework as an installed app inside the apps.py of the polls app so that it's automatically installed whenever polls is installed on a project? -

Django: How to make form conditional?
I have a form with two fields. The user should be required to only select one of the two. Not both and not none. I tried solving this by overwriting the clean method as described in the Django Doc: forms.py class ConfigureWorkout(forms.Form): first_exercise = forms.ModelChoiceField(empty_label="select", label="Choose First Exercise", queryset=FirstExercise.objects.all(), required=False) sec_exercise = forms.ModelChoiceField(empty_label="select", label="Choose Sec Exercise", queryset=SecExercise.objects.all(), required=False) def clean(self): first_exercise = self.cleaned_data.get("first_exercise") sec_exercise = self.cleaned_data.get("sec_exercise") if first_exercise and sec_exercise: raise forms.ValidationError("Enter either a First Exercise or a Secondary Exercise.") else: return self.cleaned_data views.py def configure(request): configure_workout = ConfigureWorkout() if request.method == "GET": return render(request, "userprofile/some.html", configure_workout) else: return render(request, "app/other.html") template <form action="{% url 'configure' %}" method="POST"> {% csrf_token %} {{ configure_workout }} <input type="submit" name="configuration_completed"> </form> However, if I test this by selecting both fields in the form, there won't be an error displayed/raised. I pass the form successfully and get sent to "other.html". What am I missing? Thanks so much in advance for any help :) -
