DJango, the preivous post or the next post according to that category list
I am studying to develope a blog website using DJango's generic view class. I categorized blogs into categories. If you select a blog from the full list and go to the detail page, you have implemented the ability to go to the previous post and the next post using "previous()" and "next()" in that post. I want to select a blog from a category list and move it to the preivous post or the next post according to that category list, but I don't know how. What can I do? models.py class Post(models.Model): .......... def prev(self): return self.get_previous_by_created_at() def next(self): return self.get_next_by_created_at() views.py class PostListByCategory(PostList): def get_queryset(self): slug = self.kwargs['slug'] if slug == 'no_category': category = None else: category = Category.objects.get(slug=slug) return Post.objects.filter(category=category).order_by('-pk') def get_context_data(self, **kwargs): context = super(PostListByCategory, self).get_context_data() slug = self.kwargs['slug'] if slug == 'no_category': category = 'None' else: category = Category.objects.get(slug=slug) context['category'] = category return context post_detail.html .............. <div class="row row-cols-auto"> {% if object.next %} <div class="col"> <a href="{% url 'tube_detail' object.next.pk %}" class="btn btn-sm pt-1 pb-1 bg-light" title="Prev"> <i class="bi bi-caret-left-fill" style="color:#dd3535"></i> </a> </div> {% endif %} <div class="col"> <a href="{% url 'tube_list' %}{% if request.GET.category %}category/{{ request.GET.category}}{% endif %}" class="btn btn-sm pt-1 pb-1 bg-light" title="LIST"> … -

Type error when changing model object in admin
When I try to change an object in django admin, I get a Type error. This happens with all the objects of that model, but not with other models. I suspect there is something wrong in my model, or at least something that django admin doesn't appreciate. Here is the error: TypeError at /admin/events/evenement/10/change/ type object argument after ** must be a mapping, not QuerySet Request Method: GET Request URL: http://127.0.0.1:8000/admin/events/evenement/10/change/ Django Version: 4.1.5 Exception Type: TypeError Exception Value: type object argument after ** must be a mapping, not QuerySet This is my model class Evenement(models.Model): name = models.CharField(max_length=50) url_name = models.SlugField(max_length=50, blank=True) datum = models.DateField() locatie = models.CharField(max_length=100) omschrijving = models.TextField() evenement_type = models.ForeignKey(EvenementType, on_delete=models.PROTECT) ideal = models.BooleanField() aantal_honden_toegestaan = models.IntegerField(default=2) annuleren_toegestaan = models.BooleanField(default=True) alleen_flatcoat = models.BooleanField(default=False) secretariaat = models.ForeignKey(Group, on_delete=models.PROTECT, limit_choices_to=limit_secretary_choices) publicatiedatum_vanaf = models.DateField() inschrijven_vanaf = models.DateField() inschrijven_tot = models.DateField() onderdelen = models.ManyToManyField(Onderdeel, blank=True) prijs_leden = models.DecimalField(max_digits=5, decimal_places=2) prijs_niet_leden = models.DecimalField(max_digits=5, decimal_places=2) extra_onderdelen = models.ManyToManyField(ExtraOnderdeel, blank=True) def __str__(self): return '{} ({})'.format(self.name, self.datum.strftime('%d-%m-%Y')) class Meta: verbose_name_plural = "Evenementen" If more info is needed I will provide of course.

Is there a proper filter for Django Rest Framework to work with PostgreSQL InetAddressField
I am using DRF and PostgreSQL to store IP, Subnet and IP Range data. For the filters I wanted to create a filter that resolves the given reach string and checks if a given IP is not only an exact match, but also part of a subnet or IP range in the database. PostgreSQL does have a number of operators that can be used for a lookup in InetAddressFields. PostgreSQL Documenation But it seems none are supported by Django/DRF. The django.contrib.postgres.fields package seems to have none of the network address fields. Is there a well supported module or any other way to implement proper filters for InetAddressField in DRF? -
Django project crashes server when admin backend is accessed
Problem I am running apache2 on my local ubuntu server. I set up a Django project using django-admin startproject site and set up my virtual host to use a WSGI Daemon process to run the Django project. This worked and the site is accessible through its IP 192.168.1.3. When I go to /admin, it allows me to log in and see the initial backend but loads for 5 minutes then goes to a 500 error when I click anything or reload, even when trying to access the non-admin index page. This persists until I run systemctl restart apache2 and completely restart apache or wait ~10-15 minutes until it fixes itself (only to break again immediately if I access /admin pages). Versions Django version 4.1.5 mod-wsgi version 4.9.4 My Attempts If I run the project with python manage.py runserver, I can access it on 192.168.1.3:8000 and fully use the /admin backend, even creating new users, etc. I then thought it was the WSGI Daemon process somehow messing it up, so I followed the linked section of this page: https://pypi.org/project/mod-wsgi#using-mod-wsgi-express-with-django and ran the site with python manage.py runmodwsgi. The site completely works on 192.168.1.3:8000 along with the /admin, and I can create … -

How to send JSON from NodeJS to Django?
The architecture of our app uses NodeJS and Django together. I need to send a JSON data as a HTTP post from NodeJS to Django without receiving any request before that from Django. Because, there is a function in NodeJS that generates and returns JSON data such that whenever this data returned, NodeJS must send (post) it to Django. I don't know any thing about that and have not any idea for that. What should I do? What APIs/modules do I need to use and how should I work with NodeJS and Django to fulfill it? -

Django - Two forms on one page, how can I maintain URL parameters when either form is submitted?
I'm building an application that contains a list of meals, where each meal has various filters, a price, and a rating. The filters are like tags; the user can select multiple, and the page only shows the meals that have the selected filters. The price and ratings are integers, and the user can sort by either price or rating, which sorts the meals (cheapest -> most expensive for price, highest -> lowest for rating). I have built two forms in Django, one for filters and one for sorting, and they both work on their own. However, let's say I submit the sorting form to sort by price; when I do this, it does sort by price, but it removes all of the prior filters I had submitted. Below are the important pieces of code relevant to this problem: views.py def meals(request): meal_list = Meal.objects.all() tags = Tag.objects.all() reviews = Review.objects.all() filter_form = FilterForm(request.GET or None) sorting_form = SortingForm(request.GET or None) sort = "" active_filters = [] if filter_form.is_valid(): tags = filter_form.cleaned_data.get('tags') for tag in tags: meal_list = meal_list.filter(tags__name=tag) active_filters.append(tag) if sorting_form.is_valid(): sort = sorting_form.cleaned_data.get('sort') if sort == "price": meal_list = meal_list.order_by('price') else: meal_list = meal_list.order_by('-rating') paginator = Paginator(meal_list, 8) page_number … -

so I have a problem with some variables, which are coming from an dictionary iteration: for rank in ranked_stats: if rank['queueType'] == "RANKED_FLEX_SR": flex_rank_name = "Ranked Flex" flex_tier = rank["tier"] flex_rank = rank['rank'] totalrank_flex = flex_tier + " " + flex_rank winrate_flex = rank['wins']/(rank['wins']+rank['losses']) winrate_flex *= 100 winrate_flex = "{:.2f}%".format(winrate_flex) wins_flex = rank['wins'] losses_flex = rank['losses'] else: flex_rank_name = "None" flex_tier = "None" flex_rank = "None" totalrank_flex = "None" winrate_flex = "None" wins_flex= "None" losses_flex = "None" for ranksolo in ranked_stats: if ranksolo['queueType'] == "RANKED_SOLO_5x5": solo_rank_name = "Ranked Solo/Duo" solo_tier = ranksolo['tier'] solo_rank = ranksolo['rank'] totalrank_solo = solo_tier + " " + solo_rank winrate_solo = ranksolo['wins']/(ranksolo['wins']+ranksolo['losses']) winrate_solo *= 100 winrate_solo = "{:.2f}%".format(winrate_solo) wins_solo = ranksolo['wins'] losses_solo = ranksolo['losses'] else: solo_rank_name = "None" solo_tier = "None" solo_rank = "None" totalrank_solo = "None" winrate_solo = "None" wins_solo= "None" losses_solo = "None" These are the loops for this dictionary: [{"leagueId": "0b36ed94-33bc-43e3-aa39-3bff2350f76e", "queueType": "RANKED_SOLO_5x5", "tier": "BRONZE", "rank": "II", "summonerId": "___hidden__", "summonerName": "lantern is lava", "leaguePoints": 57, "wins": 8, "losses": 5, "veteran": false, "inactive": false, "freshBlood": false, "hotStreak": false}, {"leagueId": "52002724-73b2-49bc-ad7b-ae58c64f2623", "queueType": "RANKED_FLEX_SR", "tier": "BRONZE", "rank": "II", "summonerId": "__hidden__", "summonerName": "lantern is lava", "leaguePoints": 1, "wins": 5, "losses": 5, "veteran": false, "inactive": false, "freshBlood": false, … -
How to set SSL on another port besides port 80 for react/django/nginx app
Here is my nginx.conf. SSL works on port 80/443, and I can go to the url mynacode.com with https, however I also want to access my backend on port 8000 using secured https connection. How can I do that? Right now, I can access my backend with an insecure connection i.e. http://www.mynacode.com:8000. I would like to use a secured url https://www.mynacode.com:8000 as well. upstream api { server backend:8000; } server { listen 8080; server_name mynacode www.mynacode.com; location /.well-known/acme-challenge/ { root /var/www/certbot; } location / { return 301 https://$host$request_uri; } } server { listen 443 ssl; server_name mynacode www.mynacode.com; ssl_certificate /etc/letsencrypt/live/www.mynacode.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.mynacode.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; location / { proxy_read_timeout 300s; proxy_connect_timeout 75s; root /var/www/react; try_files $uri /index.html; proxy_set_header Host $host; } location /api/ { proxy_read_timeout 300s; proxy_connect_timeout 75s; proxy_pass http://api; proxy_set_header Host $http_host; } } I've tried searching answers on stackoverflow but have been unsucessful so far. Any help would be appreciated! -
