Django model filter with default value
I wanna do something similar as here, but I want a filter with default value if it's not passed as parameter. E.G: class MyUserManager(models.Manager): def get_queryset(self, is_active=True): return super().get_queryset().filter(is_active=is_active) class User(AbstractUser): # ... manager = MyUserManager() So I don't have to remember to filter with is_active=True every time since I will want only active users all the time, except when I intentionally pass is_active=False. I don't think get_queryset() override works for this case. -

Django: How to dynamically store user data in sessions?
I am trying to create different django-allauth signup forms for different types of users. So different forms for different user types. Once a user selects a user type (example: "I want to sign up as a vendor"), they should be redirected to a different form where they will fill up other signup and profile details before email confirmation and login. I have one signup form working, but not multiple. Currently I have a general purpose form assigned to users/accounts/signup/ but I also want a vendor specific signup form assigned to users/accounts/signup_vendor/. The best possible solution I've found is provided by the django-allauth author, stating: "There are multiple ways to approach this. You could store the desired user type into the session, and dynamically construct your form fields depending on that. Or, you could allow for the user to make up his mind at any time by simply adding a "profile type" to the sign up form. Basically, the fields in the signup form would have to be the union of all possible fields, and perhaps you would want to add some Javascript to dynamically show/hide some fields depending on the type chosen. I would recommend an approach where the user … -

Django REST Framework PDF Generation
I am currently developing the back-end for a mobile application using Django REST Framework. The app has a feature where the user can request a pdf report. I am not sure whether to use ReportLab to generate the report or to create an html template and then convert that to a pdf. -
Django Channels - Duplicates with consumers on multiple servers with load balancer with separate redis server
Issue concerns duplicate messages received thanks to having multiple Django servers, with django channels consumers, accessing a separate redis server. I am running 2 identical instances of my Django server with a load balancer. The channels consumers in these servers access a separate redis server. The issue is that currently I am receiving duplicate messages as I think each consumer is separately fetching from redis and sending to the destination. (If I turn one of the servers off my duplicate messages go away). Wondered what the common / best solution to this was? One thought was trying to target different databases redisurl/0, redisurl/1 for each server ... however this raises issues as I don't know to which one my load balancer will direct traffic for other parts of the application. Thoughts appreciated hahah! Using: Django 2.2 Channels 2.4.0 Channels-Redis 3.1.0 Redis 6 -
Django pagination by date (week)
I am making a website that displays this week's soccer games from the day you open the website to six days later (current week), and i want to paginate by date. example <previous> <19 feb - 25 feb> <next> then when i press next <previous> <26 feb - 4 march> <next> in views.py. matches is a list of dictionaries, each dictionary is a single game that contains the date of the game and other info and its sorted by date def home(request): start = datetime.now().date() end = today + timedelta(6) matches = request_games(today, after_week) return render(request, "sporty/home.html",{ "matches": matches, "start" : start, "end": end }) in home.html {% for match in matches %} //match info {% endfor %} -
Django Logging: Output all Logger messages to a file
I'm trying to do some debugging and cannot figure out how I can get all the usual server output that I would normally get on a development server. Here's my logging file: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'catch_all_logger': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, 'somelogfile.log'), }, }, 'loggers': { 'django': { 'handlers': ['catch_all_logger'], 'level': 'DEBUG', 'propagate': True, }, 'django.request': { 'handlers': ['catch_all_logger'], 'level': 'DEBUG', 'propagate': True, }, 'django.server': { 'handlers': ['catch_all_logger'], 'level': 'DEBUG', 'propagate': True, }, 'django.security.DisallowedHost': { 'handlers': ['catch_all_logger'], 'propagate': True, }, 'django.security.csrf': { 'handlers': ['catch_all_logger'], 'propagate': True, }, }, } When I do cat somelogfile.log, I get almost useless information: Bad request: /url/where/bad/request However, the documentation says that django.server for instance will show status code and a message with it as extra context on the INFO level with HTTP 5XX as ERROR and 4XX as WARNING. Do I have the logging level setup incorrectly? Would love some guidance as I'm puzzled. -
Multiple Values into initial form data
I am attempting to render a form which will have certain fields prefilled based on the Primary Key. Im currently only able to successfully prefill one field (Project). Do I have to define all the other fields in my view? This is my Model class Document(models.Model): DOC_TYPE = ( ('Proposal', 'Proposal'), ('Invoice', 'Invoice'), ('Receipt', 'Receipt'), ('Other', 'Other') ) docName = models.CharField("Document Name", max_length=1000, null=True) docType = models.CharField("Document Type", max_length=10, null = True, choices=DOC_TYPE) company = models.ForeignKey('project.Company', on_delete=models.PROTECT, blank = True, null = True) customer = customer = models.ForeignKey('customer.Customer', on_delete=models.PROTECT, null = True) project = models.ForeignKey('project.Project', on_delete=models.PROTECT, blank = True, null = True) docFile = models.FileField("Document", upload_to='newdocuments/') note = models.TextField("Note About Document", blank = True, null = True) dateUpload = models.DateTimeField(auto_now_add=True) This is my View def ProjectAddDocument(request, pk): project = Project.objects.get(id=pk) form = ProjectAddDocumentForm(initial={'project':pk}) if request.method == 'POST': form = ProjectAddDocumentForm(request.POST) if form.is_valid(): form.save() return redirect('file_list') context = {'form':form} return render(request, 'project/adddocument.html', context) This is my URL path('adddocument/<int:pk>/', views.ProjectAddDocument, name='proj_document'), This is my Form class ProjectAddDocumentForm(ModelForm): class Meta: model = Document fields = ['docName', 'docType', 'company', 'customer', 'project', 'note', 'docFile'] -
How to validate and redirect on fail in CreateView get
I am trying to do some sanity checks in a CreateView get request and want to redirect user to a different URL in case the sanity checks fail. How can I achieve this? For example: class JobCreateView(LoginRequiredMixin, CreateView): model = Job form_class = JobFormClass # This does not let me redirect on return since a dictionary return is expected and redirect is not acceptable def get_context_data(self, **kwargs): if not self.request.user.is_superuser: messages.add_message( self.request, messages.ERROR, _("You are not authorized! Bugger off!") ) return redirect("home") # The user is good to proceed return super().get_context_data(**kwargs) This gives me back the following error: context must be a dict rather than HttpResponseRedirect. I am using get_context_data because I don't know what to use to be honest. Feel free to suggest something better. My use case in not really a super user check, that just felt like a better example -
Best practice for saving new model instance in Django Rest Framework
I'm new to DRF and I can't wrap my head around where to save new model instances when I POST to my endpoints. I need to overwrite my def create() method because I'm managing nested objects in my queries. I've noticed that I can save new instances from the model Serializer ( def create(self, validated_data)) but also from the associated class view ( def create(self, request)) What's the best practice here? I'm pretty sure I'm confusing major concepts, please indulge me! -
