Django REST Framework - Set request in serializer test for ApiClient
I already read: Django REST Framework - Set request in serializer test?. And it doesn't work for me! Because I'm using APIClient and not RequestFactory like him. I built a web app where the back-end is implemented using the Django REST Framework. Now I'm writing unit tests and I have come across a problem in testing my serializer methods. Here is one example of a serializer method I'm struggling with: def get_can_edit(self, obj): request = self.context['request'] user = User.objects.get(username=request.user) return user == obj.admin When trying to call this from the test, first I declare an instance of the serializer: But now I need self.serializer to have the correct request when get_can_edit does self.context.get('request'). I've created a fake request with the correct information using APIClient: self.client = APIClient() self.client.force_authenticate(user) conference = a_fake_conference res = self.client.get('conference:conference-detail'. args=[conference.id]) serializer = ConferenceSerializer(conference, context={WHAT_IS_REQUEST?}) # I'm using a dict as context but the request gave me an error: context={'request': { 'user': user }} sert.assertEqual(res.data, serializer.data) Now I am stuck because I am unsure how to add request1 to serializer such that request = self.context['request'] will return Thanks. -
Django: dbbackup displays pg_dump: error: too many command-line arguments
I've installed the django-dbbackup package and from what the Documentation tells, i need to run python manage.py dbbackup but it generated error pg_dump: error: too many command-line arguments from what i have seen in the logs dbbackup.db.exceptions.CommandConnectorError: Error running: pg_dump database_name --host=127.0.0.1 --port=5432 --username=postgres --no-password --clean From what i have known, the correct command for pg_dump is to include the database name in the last part but the dbbackup include the database name first. Anyone know the fix for the Django-dbbackup? -

How does @cache_page enable server side caching?
https://docs.djangoproject.com/en/3.0/topics/cache/ says "The cache system requires a small amount of setup. " It seems I have to setup something to make server side caching work. I didn't do any settings, I solely put @cache_page on my method in view.py. I run the server and request the page, only the first request executes the print statement. I think the caching is kicking in. So what caching backend is it using? -
Frontend receives 403 error when logged in if Django admin is also logged in
I'm trying to understand if I can be logged in as a user in both the django admin and frontend at same time in development mode. For some reason both won't work. If I log out of admin I can request data and do some crud operations in the frontend. If I'm logged in the admin and logged in the frontend all crud like operations receive a 403 error. I'm using django/backend nuxt/fronend and docker. What do I need to do in order to have both logged in and working on data? -

Django: file upload folder relative runserver command
I have a small form for file upload. #import os from .models import Pkvjanosch def handle_uploaded_file(f, rgauswahl): #PROJECT_PATH = os.path.abspath(os.path.dirname(name)) d = Pkvjanosch.objects.filter(rg_id = rgauswahl) dateizusatz = d[0].rgsteller + " " + d[0].rgdatum.strftime("%d.%m.%Y") with open('documents/' + dateizusatz, 'wb+') as destination: #with open(PROJECT_PATH + '/documents/' + dateizusatz, 'wb+') as destination: for chunk in f.chunks(): destination.write(chunk) When I run the runserver with python3 /var/services/[abbreviated]/DjangoProject/abrechnung/manage.py runserver 0:8000 from the root folder of the django app and I use this form, it works fine and the uploaded file ends up in the document folder. But if instead I start the runserver from within the documents folder, this results in an error. From the error message [Errno 2] No such file or directory: '[abbreviated]/DjangoProject/abrechnung/rgeingabe/documents/documents/filename.pdf' I can see that the path gets mixed up and that the folder document now is nested in itself. So, how can I resolve this without using an absolute path? Best regards -
How to get one of reverse foreign-key records when in a model queryset
I'm working on a django website for keeping track of devices in the network. I have a model Device: class DeviceManager(models.Manager): def get_queryset(self): return super().get_queryset().annotate( num_interfaces=Count('interface', distinct=True)) class Device(models.Model): objects = DeviceManager() uuid = models.UUIDField() name = models.CharField(max_length=30) class Meta: _base_manager = DeviceManager() and then I have model Interface: from .models import Device class Interface(models.Model): ip = models.GenericIPAddressField() device = models.ForeignKey(Device, on_delete=models.CASCADE) When displaying a list of devices, I need to list the number of interfaces for each device. So I created the Manager which pulls the count with one query, instead of having a separate query for each device in the list. Now I want to display a random IP for each device. It doesn't which one, if a device has multiple interfaces. I started writing another .annotate to my DeviceMangerand I am not sure what to do. I was thinking about using a subquery, something like: subquery = Interface.objects.filter(ip=OuterRef('ip')) so: class DeviceManager(models.Manager): def get_queryset(self): subquery = Interface.objects.filter(device_id=OuterRef('device')) return super().get_queryset().annotate( num_interfaces=Count('interface', distinct=True)).annotate( ip=Coalesce(Min(Subquery(subquery('ip'))), None) But then I realized that Interface depends on Device, and so I can't refer to Interface until Device is fully defined, so definitely not in DeviceManager What is the best way of doing this? -
Python for loop in Django returning random value in dictionary
I have a Wagtail page displaying the routing link block inside it and I'm adding an icon to the routing link model to display with title in the block on main page. In the main page I'm getting the context for uploaded file field for icon as below: def get_context(self, request): context = super().get_context(request) routing_links_queryset = self.routing_links for link in routing_links_queryset: i_link = link.link_icon if i_link: try: with i_link.icon.open() as file_obj: data = file_obj.read() data = data.decode("utf-8") context["iconlink_data"] = data except OSError: pass return context link_icon is field in routing_links model and icon is Filefield in Icon model. Now this is returning the context on the main page but if there are 2 routing link blocks on the main page, it will render the same icon for both. Do I have to append the context in each iteration? How exactly I could append in this case or any alternative way to do this? -

Sending data between views in Django
I want to send data between 2 views in Django. Main logic is that on main mage I have a simple form where I input url. After submit I scrap data from this url and redirect to endpoint /bokeh. From this endpoint I want to go to endpoint /days (from the navbar) and operate on the same given URL. I was trying to use session, but it didn't work well. My code looks like: views.py def home(request): if request.method == 'POST': url = request.POST['url'] request.session['url'] return redirect('bokeh',url=url) return render(request,'home.html') def bokeh(request,url): cl = CalculationLogic() return cl.get_data_from_url(request,url) def days(request,url): cl = CalculationLogic() url = request.session.get('url') return cl.show_days_of_the_week(request,url) So, after sending data from home.html to bokeh, everything is fine and I do my CalculationLogic. When I want to go to days I get NoReverse Match error: NoReverseMatch at /days/https://github.com/USER/PROJECT/commits/master Reverse for 'days' with keyword arguments '{'url': ''}' not found. 1 pattern(s) tried: ['days/(?P<url>.+)'] and my urls looks like: urlpatterns = [ .... url(r'^days/(?P<url>.+)',views.days,name='days'), .... ] in my base.html file I have: <body> <nav> <a class="nav-link" href="{% url 'days' url=url %}">Days</a> </nav> </body> Does anyone know why this soulution does not work? -
Django 3 - Making Model's FK Dropdown Display Current User's Data Only
I'm creating my first app with Django and still have a lot to learn, but right now I am completely stuck and need some help. I have a model for Customers and Tickets. I have it so different users can save new customers/tickets and only view their data from the dashboard once logged in. However, when creating a new ticket, there is a dropdown option to select customer for the ticket - and the current user is able to see every users customers.
