do not display already selected items as choices in the dropdown in django admin inline but preserve already selected
I am using Tabularinline class inside the django admin for many to many relation. I want to filter the queryset so already selected can't be chosen. I tried to override formfield_for_foreignkey method and it partially does the job. Choices are in the desired they (What is already selected are not present in the choices) but the default state is empty for the fields which already exist and when I try to submit a form it throughs an error indicating that the field is required (which should be this way) I don't know how to achieve this goal without overriding the admin template This is how the admin panel looks like -
Django Rest API Cache with Radis & seeking sugestion
Problem I have a backend with Django (Wagtail CMS) and a frontend with react. I am using them as a news site. I am new in Django and my other teammate manages the front end. I am providing them with wagtail's default API with some customization(I have exposed all needed fields in BaseAPIView). In my API there were 25 blog posts for the first time and now there are 60 posts. The first time the API loading time was 1.02 sec and now the API load time is 1.69sec. I am afraid of what will happen when the posts hit 5000+! Because I am not limiting anything in the API. Plan I am planning to use radis cache for the API. But I can't understand what should I set in the API views! because my API views is this. #api.py from wagtail.api.v2.views import PagesAPIViewSet,BaseAPIViewSet api_router = WagtailAPIRouter('wagtailapi') class ProdPagesAPIViewSet(BaseAPIViewSet): renderer_classes = [JSONRenderer] filter_backends = [FieldsFilter, ChildOfFilter, AncestorOfFilter, DescendantOfFilter, OrderingFilter, TranslationOfFilter, LocaleFilter, SearchFilter,] meta_fields = ["type","seo_title","search_description","first_published_at"] body_fields = ["id","type","seo_title","search_description","first_published_at","title"] listing_default_fields = ["type","seo_title","search_description","first_published_at","id","title","alternative_title","news_slug","blog_image","video_thumbnail","categories","blog_authors","excerpt","content","content2","tags","story_type"] nested_default_fields = [] def get_queryset(self): return super().get_queryset().filter(story_type='Story').order_by('-first_published_at') name = "stories" model = AddStory api_router.register_endpoint("stories", ProdPagesAPIViewSet) Will adding radis cache in API solve the loading problem or should I add … -
Django - command createsuperuser creates superuser in the default database when passing the --database parameter
I have three Postgre databases in my project: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'default', 'USER': 'user', 'PASSWORD': 'password', }, 'clients_db': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'clients_db', 'USER': 'user', 'PASSWORD': 'password', }, 'other': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'other', 'USER': 'user', 'PASSWORD': 'password', }, } And three apps: clients, users and myapp. The app clients have a router for the clients_db database: class ClientsRouter: route_app_labels = {'clients'} def db_for_read(self, model, **hints): if model._meta.app_label in self.route_app_labels: return 'clients_db' return None def db_for_write(self, model, **hints): if model._meta.app_label in self.route_app_labels: return 'clients_db' return None def allow_relation(self, obj1, obj2, **hints): if ( obj1._meta.app_label in self.route_app_labels or obj2._meta.app_label in self.route_app_labels ): return True return None def allow_migrate(self, db, app_label, model_name=None, **hints): if app_label in self.route_app_labels: return db == 'clients_db' return None The other two apps uses the same database.

How can I allow the user to edit comments in a Django Blog using DetailView and UpdateView on the same page?

Programmatic login succeeds, but not recognized
I have a magnet link feature where my web app sends a login URL with a username & one-time token encrypted. When clicking the link on the email, the user is sent to an authentication where I programmatically log in and then redirect to the member page. Authentication and login are successful, but when I redirect to the main page, Django sends the user back to the login page. However, when I click the logo, the main page shows. authentication & login code def magnet_link_login(request, *args, **kwargs): if request.user and request.user.id != None: return redirect('stream:home') magnet_token = request.GET['key'] if 'key' in request.GET else '' decrypted_token = decrypt_text(magnet_token) split_texts = decrypted_token.split('&') if len(split_texts)<2: #invalid and redirect to an invalid magnet link page pass uname = split_texts[0].split('=')[1] auth_token = split_texts[1].split('=')[1] #fetch the user record acc = Account.objects.get(slug=uname) if not acc: #error and redirect to an invalid account name page pass #validate and login try: logged_user = authenticate(username=acc.username,password=auth_token) if logged_user is not None: login(request, logged_user) return redirect('stream:home') else: return redirect('invalid-link') except Exception as e: print(e) return redirect('invalid-link') My member page (stream:home) is a CBV. class Home(LoginRequiredMixin, ListView): paginate_by = 6 context_object_name = 'content_list' ***SOME STUFF HERE*** def get_queryset(self): *** SOME STUFF HERE*** def … -
Django: annotate a model with multiple counts is super slow
I'm trying to annotate a model that has multiple relationships, with multiple counts of those relationships. But the query is super slow. Campaign.objects.annotate( num_characters=Count("character", distinct=True), num_factions=Count("faction", distinct=True), num_locations=Count("location", distinct=True), num_quests=Count("quest", distinct=True), num_loot=Count("loot", distinct=True), num_entries=Count("entry", distinct=True), ) When I mean super slow, I mean it: it takes multiple minutes on my local MacBook Pro with the M1 Max 😰 And there aren't even that many row in these tables. If I simply fetch all campaigns, loop over them, and then get the counts of all these related objects in separate queries, it's a LOT faster (at the cost of doing number of campaigns * 6 queries). But that is so much more code to write, can't this query be optimized somehow? -

Get slug name list by url path name
I am reverse-engineering django urlpatterns. For my purpose, I need to dynamically know the list of slug names developers chose to use within url. Example: path("<slug:membership_slug>/<slug:parent_slug>/data/", rzd.ReportingUnitDataView.as_view(), name="hierarchy.item.data"), So, in the world, where everyone writes perfect code, my function should take "hierarcy.item.data" and spit out ["membership_slug", "parent_slug"] I looked at the reverse function, hoping it would return something useful without kwargs, but it does not. Have been googling like Neo, but to no avail. But the hope does not leave my heart... somewhere django should hold all that urlpatterns stuff! I still believe. Perhaps you can at suggest how to get a hold of list of urls, even if in the raw format, that would already be a help. Thank you. -

update only targeted element with ajax
I'm trying to update my cart page with ajax when someone increases or decreases the quantity of the products, my view logic is fine. My issue as I can infer is targeting the class "ajax_updater", as soon as I hit the quantity buttons ajax works, but instead on just the specific product, it targets all the products' quantity with the same class ".quantity-style" and changes the value as per the targeted product, so, if the quantity for product A is 4 after ClickEvent, the quantity for product B, D, F gets targeted and changed to 4 too, what could be a solution? {% for item in items %} <div class="quantity"> <p id="quantity-style" class="quantity-style">{{item.quantity}}</p> <div class="quantity-arrows"> <img data-product="{{item.product.id}}" class="ajax_updater" data-action="add" src="{% static 'shop/images/arrow-up.png' %}"> <img data-product="{{item.product.id}}" class="ajax_updater" data-action="remove" src="{% static 'shop/images/arrow-down.png' %}"> </div> </div> {% endfor %} function update_arrow() { $.ajaxSetup ({ cache: false }); var spinner = '<i class="fas fa-circle-notch fa-spin" style="font-size:15px;" alt="loading" ></i>'; $(".quantity-style").html(spinner).load(update_quantity_url); console.log(update_arrow_url); } $('.ajax_updater').click(function () { update_arrow(); console.log('hit hit'); }); -
What is the difference between SimpleTestCase.settings() and django.test.override_settings?
Django provides different ways to change settings(documentations) in a test in different levels (TestCase class, test method, context manager). I understand the difference between override_settings and modify_settings, but I can't get the difference between SimpleTestCase.settings() and django.test.override_settings() when being used as a context manager. Is there any difference in functionality or preference in which one to use? -
(Django / Nginx / Gunicorn) HTTPS fails to serve pathed directories on my site
Pretty new to Nginx and web deployment in general. I have a site I am aiming to deploy using a DigitalOcean droplet. Right now it is working, but only with http://[SERVER-IP] (here) Although the site does load with HTTPS (here), no domain.com/[ X ] sites work. The aim is to make get all URLs within https://rejesto.com functioning normally and leading to their respective sites. For context, all links on the page are provided by Djagno's {% url '[url]' %} tag system; they work as intended locally, and using http://[SERVER-IP]/[ X ]. I'm assuming that the issue is within the Nginx config files because: http://46.101.92.95/blog leads to the correct page. (for better or for worse) https://rejesto.com/blog does not work. Here is (what I believe to be) the relevant config file: /etc/nginx/sites-available/rejesto.com: server { server_name rejesto.com www.rejesto.com; location / { try_files $uri $uri/ =404; include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/rejesto/myprojectdir; } listen [::]:443 ssl ipv6only=on; # managed by Certbot listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/rejesto.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/rejesto.com/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by … -

How to mark words that match words from a list in a django form's textarea using javascript?
I have the following form: class TestForm(Form): testfield = CharField(widget=Textarea(attrs={'rows': 10, 'id': 'test'}), label='Input test text here') Rendered to my template along with the following list as context: dummy_list = ['hi', 'hello'] I'm trying to make a button which I can click in my template which makes words in the form bold if they are contained within the list.

Django: relations between two objects of the same model
I have created this model: class Process(models.Model): name = models.CharField('Process name', max_length=50, unique=True) owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, max_length=50, null=True, verbose_name='Process owner') I want to create multiple processes and from those build a hierarchy. Here is a hierarchy model: class Hierarchy(models.Model): name = models.ForeignKey('process.Process', on_delete=models.CASCADE, verbose_name='Sub process name') name = models.ForeignKey('process.Process', on_delete=models.CASCADE, verbose_name='Main process name') order = models.IntegerField('Process order', default='1') Obviously this doesn't work as the 'name' fields in hierarchy model interfere with each other. I wouldn't want to create models MainProcess and SubProcess as some SubProcesses might have more SubProcesses etc. What would be the right way to build this type of model/hierarchy? This might be very basic issue, but I couldn't find any related issues to apply a solution from, so any help would be appreciated. -

Wagtail dumpdata modellogentry null values
Having a problem with dumpdata command in Wagtail v.3.0.3. Some of the entries for the table pagelogentry have data set to null and not the expected {}. It is not all the values.

I'm not sure what the right course to fix the data is here. -
