How can I assign different platform ID to multiple candidates before saving it to the database?
I have a formset that takes in 7 candidates and each candidate should have a platform id. When I try to assign a platform to a candidate in a for loop, it only assigns the first platform ID to all candidates. here is my view fuction. def addcandidate(request): party = PartyList.objects.all() partylist_form = PartylistForm() PlatformSet = formset_factory( PlatformForm,extra=7) candidateFormSet = formset_factory(CandidateProfileForm,extra=7) form1 = PlatformSet(prefix='platform') form2 = candidateFormSet(prefix='candidate') if request.method == 'POST': partylist_form = PartylistForm(request.POST) form1 = PlatformSet(request.POST, prefix='platform') form2 = candidateFormSet(request.POST,request.FILES,prefix='candidate') if form1.is_valid() and form2.is_valid() and partylist_form.is_valid(): try: partylist = PartyList.objects.get(partylist_name=request.POST['partylist_name']) except ObjectDoesNotExist: partylist = partylist_form.save() for f1 in form1: p1 = f1.cleaned_data['platform'] p2 = f1.cleaned_data['platform2'] p3 = f1.cleaned_data['platform3'] try: Platform.objects.get(candidate_platform=p1) except ObjectDoesNotExist: platform = Platform(candidate_platform=p1,candidate_platform2=p2,candidate_platform3=p3) platform.save() for count,f2 in enumerate(form2): name = f2.cleaned_data['name'] img = f2.cleaned_data['Candidate_Img'] try: CandidateProfile.objects.get(name=name) except ObjectDoesNotExist: candidate = CandidateProfile(Candidate_Img=img,name=name) candidate.save() candidate.platform = platform candidate.partylist = partylist if count == 0: candidate.position = Position.objects.get(id=1) elif count == 1: candidate.position = Position.objects.get(id=2) elif count == 2: candidate.position = Position.objects.get(id=3) elif count == 3: candidate.position = Position.objects.get(id=4) elif count == 4: candidate.position = Position.objects.get(id=5) elif count == 5: candidate.position = Position.objects.get(id=6) elif count == 6: candidate.position = Position.objects.get(id=7) candidate.save() return redirect(request.META['HTTP_REFERER']) else: print(form1.errors) print(form2.errors) print(form1.non_form_errors) print(form2.non_form_errors) context = … -

Dajngo admin: more "view on site" alternatives
I am creating a fairly standard CRUD application with Django. For now I have chosen an approach where the common/complex properties can be edited using custom forms and the more exotic elements of the application must be edited with the django admin - works quite nicely. In the Django admin I really like the "View on site" link which will take me to view an object on the site. Now I would really like to other "call back into the site" functionalities: From the list view in django admin I would like to be able to have a "View on site" which takes me to a "list view" in the application. From the application view in Django admin it would be nice to have a "View on site" which takes me to an "application root" in the application. Are any such things available? -
Django admin is not accesible when DEBUG=False
I'm writing the backend for my app using django and django-rest-framework. The problem I have is that when I set DEBUG=False in my settings, the admin site (along with the browseable rest API) is no longer available, and I got a 500 response. The rest when queried/posted using JSON still works normally. This is my urlspatterns (I also tried including /admin at the top of the list) urlpatterns = [ path("", index, name="index"), path("api/", include(router.urls)), path("admin/", admin.site.urls), path("api-auth/", include("rest_framework.urls", namespace="rest_framework")), ] Since I'm creating my app using react, I'm testing a project structured in a way that all the django apps are contained in the same folder, being the main app: backend. I had to make some minor changes in the apps to accommodate this structure. For instance, this is an excerpt of how the installed apps: INSTALLED_APPS = [ ... "rest_framework", "backend", "backend.projects", "backend.tasks", "backend.subtasks", "backend.comments", ] And this is a capture of the folder tree. I think it must be something that changes in app/template discovery when changing from DEBUG=True to False. Point out that everything else apart from that works correctly: the root of my backend is serving the react app correctly, rest API works correctly as … -

Why I got "http://~" as redirect url parameter althoguh I set "https://~" to LOGIN_REDIRECT_URL in mozilla-django-oidc?
I've been trying to integrate Django app with Keycloak using mozilla-django-oidc and fix the problem as refered to in the title. I configured LOGIN_REDIRECT_URL in settings.py LOGIN_REDIRECT_URL = "https://~" and prepared Django template. {% if request.user.is_authenticated %} <p>Current user: {{ request.user.email }}</p> <form action="{{ url('oidc_logout') }}" method="post"> {{ csrf_input }} <input type="submit" value="logout"> </form> {% else %} <a href="{{ url('oidc_authentication_init') }}">Login</a> {% endif %} However I clicked the "Login", then I got the error message which is invalid redirect url because redirect url parameter was changed to http://~. I looked through the code of mozilla-django-oidc, and seemed that there's no function changing "https://~" to "http://~" as redirect url parameter and set "https://~" to LOGIN_REDIRECT_URL so there might be something wrong with reverse proxy which is Istio in my case. I haven't configured it to anything by myself so far. In case of using Ngnix, this problem can be solved like this. I'd like you to answer what's the cause of problem and how to fix it. I appreciate for your time to read this. -

Display messages/notifications in NetBox
I would like some help with messages in NetBox, please. I'm writing a custom validator and I need to display a warning message if for example a device name doesn't fit the company's policy. I can't use the standard fail method in the CustomValidator class - the edit request should be fulfilled, it's just supposed to warn the user as well. I would like to use a box message like this one, just with the warning level. I tried something like this: from extras.validators import CustomValidator from django.contrib import messages class device_validator(CustomValidator): def validate(self, instance): if instance.name is not instance.name.upper(): messages.info(request, "Names of devices should be in all-caps.") return But clearly, my syntax is wrong. I get the "Server Error" window and following message: <class 'NameError'> name 'request' is not defined How do I define the request? Could someone please give me an example how to display a message in this context? Thank you. -
How to create a Django project that allows a User to install plugins from a marketplace Just like WordPress
I would like to create a Django project that allows me to sell services as packages. Here I mean, Users should visit my market place, choose a package they want, then click on Install. Just Like WordPress. This process should automatically do configurations in the background including running the required pip install app commands add the app into installed apps make necessary migrations collect static files I'm confused on how to implement this, and need your help on this. I have been able to create a Django project, and am able to package convert apps into packages. I also understand the consequences of conflicts in migrations and circular dependencies associated with multiple apps. What I want is to allow a user of my system to be able to install a package whenever they need to add it on their options, by just clicking install. -

Django and whitenoise - caching "too much"
I am using Whitenoise to serve static files (images, css, js) for a Django site. Now my problem is that the static files seem to be "cached to much"(?) when working locally. Description of actions: Initially my static files are served correctly I edit a file in static/ I run ./manage.py collectstatic (which correctly identifies one updated file). When going to http://127.0.0.1:8000/ my browser consistently shows the old stale version of the file. I have even tried completely removing the generated staticfiles/ folder - and the browser still seems to be able to dig out an old version of the file? This is when running locally in debug mode. Do not have a consistent understanding of how it is in production, but I think it works better (as it should?) there. My configuration: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', ....

Django disable ForeignKey field in Form
