GeoDjango: Filter by distance to objects from unrelated model
I'am using geodjango and django-rest-framework to set up a gis application. Now I have two Models (Shop and BusStation) which have no relation. Now I want to filter the shops based on the fact, if there is a bus station nearby. Somesting like: .../getAllShops/?city=Berlin&busstationdistance_min=3km Is there a possibility to add such a filter into my current FilterSet?? Thanks a lot for any help! :) My Models: class Shop(models.Model): name = models.CharField(max_length=254) address = models.CharField(max_length=254) city = models.CharField(max_length=254) size = models.FloatField(null=False) website = models.CharField(max_length=254) geom = models.MultiPointField(srid=4326, null=False) class BusStation(models.Model): name = models.CharField(max_length=254) geom = models.MultiPointField(srid=4326, null=False) My ViewSet: class ShopViewSet(viewsets.ModelViewSet): queryset = Shop.objects.all() serializer_class = ShopSerializer filterset_class = ShopFilter My FilterSet: class ShopFilter(filters.FilterSet): city = filters.CharFilter(field_name="city", lookup_expr='iexact') size = filters.RangeFilter(field_name="size"); class Meta: model = Shop fields = ['name', 'city', 'size'] -
Why are users not logged in when using a customized backend in Django?
With gracious help from another member on here, I am using a customized backend that checks for two requirements to log someone in. backends.py from django.contrib.auth.backends import ModelBackend class ProfileCheckBackend(ModelBackend): def user_can_authenticate(self, user): is_active = super().user_can_authenticate(user) return is_active and getattr(user.profile, "approved", False) settings.py AUTHENTICATION_BACKENDS = [ "django_site.backends.ProfileCheckBackend", # "django.contrib.auth.backends.ModelBackend" ] This works great, but when a user tries to sign up, they need to be logged in to move to the next function: views.py def register(request): if request.method == 'POST': form = UserRegisterForm(request.POST) if form.is_valid(): user_object = form.save() user_object.is_active = True user_object.save() username = form.cleaned_data.get('username') password = make_password(form.cleaned_data.get('password1')) # user = authenticate(username=username, password=password) user = form.save() login(request, user, backend='django.contrib.auth.backends.ModelBackend') # messages.success(request, f'Your account has been created! You are now able to log in!') return redirect('sign_up_post') else: form = UserRegisterForm() return render(request, 'users/register.html', {'form': form}) @login_required() def sign_up_post(request): if request.method == 'POST': ... The login function, however, does not log the user in. How can I fix this? -

How to add in Django a non-nullable ForeignKey to an existing table?
I have the following models: class Parent(models.Model): name = CharField(max_length=80, ...) class Child(models.Model): name = CharField(max_length=80, ....) And I want to add a non-nullable foreign key as shown here: class Child(models.Model): name = CharField(max_length=80, ....) parent = ForeignKey(parent) Both tables already exists in the database but have no data. When running makemigrations Django asks for a default value. If I don't want to provide a default value, is it better to perform 2 migrations, the first one with null=True and then run a second one with null=False, before ingesting data in the DDBB? Thank you for your advice. -

Selenium - assert element exists
I'm using Selenium (Django) and am wanting to ensure that before a user logs in the 'login' button is present, but after they log in it is no longer present and is replaced with a 'logout' button.

How to get django to serve on https (443) on docker on AWS?
I have my Django backend hosted on an ec2 server. I only use it for the REST API. The frontend is in React and it is hosted already with an https certificate on Netlify. When I did this, all API calls failed because of this error: In Django Log: You're accessing the development server over HTTPS, but it only supports HTTP. I tried this, this, and this tutorial.

Running output of Python in html in Djngo
I am working on a django project. In the app's views.py I am having some outputs that I am storing in a dictionary. The views.py looks like this: from django.shortcuts import render def allblogs(request): a = request.GET['a'] b = request.GET['b'] return render(request, 'blog/allblogs.html', {'a': a, 'b':b}) I am calling these a and b in the html file. When I am just showing them without any html code like this: here are your {{a}} and {{b}} then I am getting them in the boring white page. However, when I am trying to call them in a html code, I am getting nothing. If I try to run them like this: {% a %} this gives me error: TemplateSyntaxError at /blog/ Invalid block tag on line 98: 'a'. Did you forget to register or load this tag? Request Method: GET Request URL: http://localhost:8000/blog/?the_sender=&the_amount= Django Version: 3.0.6 Exception Type: TemplateSyntaxError Exception Value: Invalid block tag on line 98: 'a'.
