get_object_or_404 only for DetailView
Im new to programming, im working on a app to study a given topic, and after I read the topic, im showing some flashcards, but I want to show only the flashcards related to the topic, but I always get more then one Deck of flashcards, probably because I'm not getting the correct deck_id.

Clearing out redis from celery tasks that has finished
I'm using celery task queue which use Redis as a message broker to run some background tasks that save results to Redis. I wanted to clear out Redis from task results that did finish because i no longer need them and so in case of having a big spike I shouldn't worry. I came across CELERY_RESULT_EXPIRES which indicates that a task result will automatically clean up after X seconds. Consider the following code: from celery import Celery CONFIG = { 'BROKER_URL': 'redis://localhost:6379/0', 'CELERY_RESULT_BACKEND': 'redis://localhost:6379/0', 'CELERY_RESULT_EXPIRES': 15, # 15 secs 'BROKER_POOL_LIMIT': 0, # redis connection get closed once task is done.. } celery = Celery('tasks', config_source=CONFIG) @celery.task(name='tasks.say_hello') def say_hello(): return "Helloooooo i just came out from the background!" say_hello.delay().get() When running the code above and having celery beat -A tasks -l info running too, then checking Redis after a while (more than 5mins) I see this: 127.0.0.1:6379> KEYS * 1) "_kombu.binding.celery" 2) "_kombu.binding.celery.pidbox" 3) "_kombu.binding.celeryev" 4) "celery-task-meta-854543d8-14ad-4bf8-9725-edcf64131bb2" 5) "celery-task-meta-fa3e267e-46d0-4488-a766-d3276b6abdeb" 6) "celery-task-meta-86c2d83c-cadd-41b9-b4ff-426607786299" Tasks 4 to 6 which were completed still there! Isn't the results supposed to clear out after 15 seconds, Am I missing something here? Thanks in advance. -
my error message is not displaying on my web site using python, Django, and html
I am using Django to make a website similar to wiki for a project. The code below is where I'm having some trouble. I want it to display an error message that I made, but it keeps saying "no item" when I put a title that isn't on the web site.

I am having problem installing wkhtmltopdf on my docker container for a Django application?
I am using pdfkit in my django application and it seems to be working fine after I installed wkhtmltopdf on my machine.

Django setting initial dropdown value from current instance?
I am trying to set the initial choices in a dropdown, on profile edit for selecting Business type. But I want the dropdown to already have the current instance' selections already chosen.

Resources for designing document management system (dms) [closed]
This is pretty open-ended, but I'm looking for guidance in designing a simple file management system, preferably in Python, though React is sufficient. The goal at the start is just a simple web app where users can sign in, upload files, and manage all of the files they've uploaded. So far, I've done a fair bit of research, and already tried using Django-Filer, though on its own I found it was too difficult to transition its admin widget to a standalone app. I've come across plenty of options, like Mayan DMS, but no options, both open source and commercial, seem reliable. I appreciate any advice. I'd rather not design it all from scratch, but with each passing day it's beginning to feel like that's what I'll have to do :( -
How to add property to Django self.request
I am using DRF and token based auth and need to frequently access a property called request.user.organization_id in my views. The organization_id is not stored in my user table, so I need to find a way to add it to the request.user object. I tried but failed at adding this property via middleware. How should I go about this? Here is my middleware code: class UserOrganizationMiddleware(MiddlewareMixin): def process_request(self, request): primary_organization = OrganizationUser.objects.get(user=request.user).first() request.user.organization_id = primary_organization.organization With my current middleware, request.user comes back as an anonymous user, even when I am logged in. My middleware is placed AFTER my authentication middleware in my settings file, but this still happens. user model: class User(AbstractBaseUser, PermissionsMixin): id = models.AutoField(primary_key=True) uuid = models.UUIDField(primary_key=False, unique=True, default=uuid4, editable=False) first_name = models.CharField(_('First Name'), max_length=50) last_name = models.CharField(_('Last Name'), max_length=50) email = models.EmailField(_('Email address'), unique=True) -
Django: passing a URL parameter to every instance of a reverse URL lookup in a template tag
Sorry if the title is unclear, I'm not sure the best way to describe the issue. I have an application with a Ticket model and a Team model. All Tickets are associated with a single Team. The issue I'm having is a problem of URL reversing. I'm trying to set it up my URLs like so: /<team_pk>/tickets/ displays a list of tickets associated with the Team specified by team_pk. So /1/tickets/ would display all of the tickets for the first Team. Both of these objects are in the app tracker. To do this, I've set up my project/urls.py files like so: project/urls.py urlpatterns = [ path('<team_pk>/', include('tracker.urls', namespace='tracker')), ] tracker/urls.py urlpatterns = [ path('tickets/', views.TicketTable.as_view(), name='ticket_list'), ] Then, inside my html templates, I have the following URL tag: href="{% url 'tracker:ticket_list' %}" This results in a NoReverseMatch error: NoReverseMatch at /1/tickets/ Reverse for 'ticket_list' with no arguments not found. 1 pattern(s) tried: ['(?P<team_pk>[^/]+)/tickets/$'] What I would like is for the reverse match to just use the current value for the team_pk URL kwarg. What I have tried to fix it: I have found the following solution to the problem, but it involves a lot of repetition, and I feel like … -
Extend django.rest_framework.serializers.ModelSerializer to model property fields?
I am using this serializer to query and return some json objects. class MyModelPathSerializer(serializers.ModelSerializer): class Meta(): model = MyModel fields = ('setup', 'path') depth=1 I am interesting in returning a property of of my model rather than a field though. class MyModel(models.Model): setup = models.ForeignKey(Setup, on_delete=models.CASCADE) @property def path(self): return '/some/path/' Is there a way to modify the serializer class so that also properties are returned? -

Follow/following system Django - how to check if user is already following
Trying to build a follow/following system with Django. The model seems to be working but I'm running into issues trying to perform an "already-following" check in my view. Here is the view: class FollowView(View): model = UserRelationships def get(self, request, username=None): user = self.request.user viewed_user = User.objects.get(username=username) if user not in viewed_user.followers.all(): UserRelationships.objects.create(user_id=user, following_user_id=viewed_user) data = {} return HttpResponse(data) At this point, a new object gets created each time I hit the "Follow" button regardless if the user is already following. Here is the UserRelationships model: class UserRelationships(models.Model): user_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="following") following_user_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="followers") created = models.DateTimeField(auto_now_add=True) And the two relevant URLs (base and specific app): path('accounts/<username>/', include('accounts.urls')) path('follow/', FollowView.as_view(), name='follow') And then I pass in the current user's username via a template tag for the HTML button. Any idea what I'm doing wrong here? Much appreciated! -

Real life implementation of HybridDetailView that can return both HTML and JSON

(Django) RQ scheduler - Jobs disappearing from queue
Since my project has so many moving parts.. probably best to explain the symptom I have 1 scheduler running on 1 queue. I add scheduled jobs ( to be executed within seconds of the scheduling). I keep repeating scheduling of jobs with NO rq worker doing anything (in fact, the process is completely off). In another words, the queue should just be piling up. But ALL of a sudden.. the queue gets chopped off (randomly) and first 70-80% of jobs just disappear. Does this have anything to do with: the "max length" of queue? (but i dont recall seeing any limits) does the scheduler automatically "discard" jobs where the start time is BEFORE the current time? -

My model looks like this: class InvoiceInfo(BaseModel): invoice_number = models.CharField(max_length=100, unique=True, null=False, blank=False, default="") delivery_date_time = models.DateTimeField() net_payable_amount = models.FloatField(default=0, null=False, blank=False) paid_status = models.BooleanField(default=False) ONLINE_PAYMENT = 'SSLCOMMERZ' CASH_ON_DELIVERY = 'CASH_ON_DELIVERY' PAYMENT_METHOD = [ (ONLINE_PAYMENT, 'SSLCommerz'), (CASH_ON_DELIVERY, 'CashOnDelivery'), ] payment_method = models.CharField(max_length=20, choices=PAYMENT_METHOD, default=CASH_ON_DELIVERY) order_number = models.ForeignKey(Order, related_name='invoice', blank=True, null=True, on_delete=models.CASCADE) def __str__(self): return 'OrderId: ' + str(self.order_number) + " " + "InvoiceNumber: " + str(self.invoice_number) And my admin.py looks like this: class InvoiceInfoAdmin(MaterialModelAdmin): list_display = ['id', 'invoice_number', 'order_number', 'delivery_date_time', 'paid_status', ] search_fields = ['invoice_number', 'order_number__pk'] list_editable = ('paid_status',) list_filter = ['created_on', 'delivery_date_time'] def save_model(self, request, obj, form, change): if obj.id: obj.modified_by = request.user obj.created_by = request.user obj.save() return super().save_model(request, obj, form, change) but when I do this, the paid_status field becomes blank in my admin panel; how can I fix this? Screenshot for reference: P.s. I am using material admin -
Django Get Foreign Key Value in Many-to-Many
relatively new to Django, so this is probably straightforward and just missing something. Given these models: class Manager(models.Model): mgrname = models.CharField(max_length=100) class Salesperson(model.Model): name = models.CharField(max_length=100) mgr_name = models.ForeignKey(SalesMgr,on_delete=models.CASCADE) class SalesList(models.Model): list_description = modesl.CharField(max_length=100) list_members = models.ManyToManyFiels('Salesperson') Each salesperson is assigned a manager (only one - managers have many salepeople). My user can create an arbitrary contact list ("SalesList") which contains any number of salespeople (salespeople can belong to many lists. A list may contain many sales people). I'm able to retrieve a list of salespeople on a selected list, but I need to include the sales manager name. How can I retrieve the manager name when the list is selected? Thank you!
