How to have a check that User must Select at least one of the two Foreign Keys in Django Rest Framework
I am trying to make a Django App. I am facing this issue that I need to bound the user to at least select one of the foreign keys. The logic being the user should have his own Idea or he needs to request one of the ideas posted by the teacher. My code looks like this.

Using Django Rest Framework to initiate data processing on the backend
I have a fully functioning Django application and I am now adding an API using Django Rest Framework. I will creating a React front end which will use the API provided via DRF. I have worked out how to use DRF to create endpoints for my models using ModelViewSets and ModelSerializers. These work fine. I now need to create an endpoint that initiates some data processing. The endpoint will need to accept a date as input and then call some code to do the processing. My standard Django application currently does this by accepting a date via a Django form and then initiating a celery task. Here is the view: class GenerateRosterView(LoginRequiredMixin, FormView): """Generate Roster View.""" template_name = "generate_roster.html" form_class = GenerateRosterForm def get_form_kwargs(self): """Pass request to form.""" kwargs = super().get_form_kwargs() kwargs.update(request=self.request) return kwargs def get_success_url(self): """Get success URL.""" return reverse("roster_generation_status", args=(self.task_id,)) def form_valid(self, form): """Process generate roster form.""" start_date = form.cleaned_data["start_date"] self.request.session["start_date"] = start_date.date().strftime( "%d-%b-%Y" ) result = generate_roster.delay(start_date=start_date) self.task_id = result.task_id return super().form_valid(form) Here is the form: class GenerateRosterForm(forms.Form): """Generate Roster Form.""" def __init__(self, request, *args, **kwargs): """Get default start date from session.""" super().__init__(*args, **kwargs) if "start_date" in request.session: start_date = datetime.datetime.strptime( request.session["start_date"], "%d-%b-%Y" ) else: start_date = … -
Django - How can I set a Model's field using the existance of a ForeignKey as a condition?
I am trying to create a Django app where there are two main models - Team and Person. A Person can use the app as an User or can belong to a Team, and, in that case, the User will be the Team. class Team(models.Model): name = models.CharField(max_length=50) team_user = models.ForeignKey( User, on_delete = models.CASCADE, null = True, blank = True ) class Person(models.Model): person_user = models.ForeignKey(User, on_delete = models.CASCADE, null = True, blank = True) team = models.ForeignKey( Team, on_delete = models.CASCADE, null = True, blank = True ) I am trying to develop a File structure like this: /root /Team_01 /Person_01 (non-User) /files.csv /Person_02 (non-User) /files.csv /Person_03 (User) /files.csv I have read the documentation and I was trying to do something with the comment from Evgeni Shudzel in this post, but my problem is that I don't know how to set the file's path for the Person model so that if the Person is member of a Team, the path is "/team_id/person_id" and if not, the "/team_id" part is excluded. The pseudocode I have in mind: if Person.team exists: files = models.FileField(upload_to="TEAM_ID/PERSON_ID/") else: files = models.FileField(upload_to="PERSON_ID/") How can I implement this pseudocode? Thank you! -
django alternative to prevent header poison
Firstly I don't speak English very well, but anyway... i know I need to use allowed_hosts, but I need to use all "*" and a header attack can cause something like: <script src = "mysite.com/js/script.js"> <script> to <script src = "attacker.com/js/script.js"> <script> or mysite.com/new_password=blabla&token=blabla8b10918gd91d1b0i1 to attacker.com/new_password=blabla&token=blabla8b10918gd91d1b0i1 But all static files are load on a nodejs server "cdn.mysite.com" and all domains are in the database, so I always take the domain from the database to compare with the request header, and use the domain from the database of data to send anything to the client: views.py: def Index(request): url = request.META['HTTP_HOST'] cf = Config.objects.first() if cf.domain == url: form = regForm() return render(request, 'page/site/home.html', {'form': form}) elif cf.user_domain == url: ur = request.user.is_authenticated if ur: config = {'data' : request.user} lojas = 'json.loads(request.user.user_themes)' return render(request, 'app/home.html', {"config":config, "lojas":lojas}) else: forml = loginForm() return render(request, 'page/users/login/login.html', {'form':forml}) else: redirect("//" + cf.domain) Would that still be unsafe to use this way? -

How to get a users lat and long via button press in Django?
I'm in the process of trying to create an app that can grab a users lat and long when a button is press/clicked. I plan on storing the lat and long inside of a model field for each individual press/click. Only to be used later on inside of an interactive map, displaying every lat and long that has been stored. Looking into Leaflet or Google Maps API to implement a map. I've read the Django documentation on GeoIP2 and I think it may be my best option but I'm not sure if there are any better options? As far as implementing GeoIP2 goes, it's really as simple as what I have below, correct? from django.contrib.gis.geoip2 import GeoIP2 g = GeoIP2() lat,lng = g.lat_lon(user_ip) model_field_example_lat = lat model_field_example_lng = lng -
Django migrate rollback multiple migrations on failure
Django migrations has excellent behavior in terms of single migrations, where, assuming you leave atomic=True, a migration will be all-or-nothing: it will either run to completion or undo everything. Is there a way to get this all-or-nothing behavior for multiple migrations? That is to say, is there a way to either run multiple migrations inside an enclosing transaction (which admittedly could cause other problems) or to rollback all succeeded migrations on failure? For context, I'm looking for a single command or setting to do this so that I can include it in a deploy script. Currently, the only part of my deploy that isn't rolled back in the event of a failure are database changes. I know that this can be manually done by running python manage.py migrate APP_NAME MIGRATION_NUMBER in the event of a failure, but this requires knowledge of the last run migration on each app. -

Ajax data manipulation when transmitting to Django CBV
I'm using django-autocomplete-light with the select2 "select multiple" widget for a M2M form. I have it set up to enable "Create New" when the input is not found. However, my model has additional required fields beyond the initial input of the "select multiple" widget. I am trying to create a way to prompt the user for the additional fields when trying to create, and then sending that data through ajax to my django view. Right now, if I pre-supply the other required fields within my view, the user can create a new object with the name that they've entered (and clicked "Create New") for, and the other fields will be determined in my view. This shows me that the code is working, but ideally I'd like to prompt the user for the additional data. I have created a prompt, however I cannot the correct syntax for transmitting the data. As an example, pretend I have a model with required fields "Name" and "Location". On the Select2 widget, the user types a "Name" which doesn't exist as an object, and clicks "Create New". Now, I'd like the script to prompt them for the location, then transmit that in as a get_or_create … -

django-tables2: Change column header link
I have created a table using django-tables2, and it displays correctly with verbose names displaying in the column headers.

certbot and apache domain name trouble
I have deployed a django web application on a linux server using ubuntu 20.10 and apache2. My site was working well before I added certbot. However, after I ran the certbot commands for apache2 and ubuntu 20.04 (because 20.10 was not listed) my site only works for for first time users who put www.my_domain_name.com. When they just put my_domain_name.com in it serves them the default apache ubuntu page which is clearly not what I want. My idea was to use rewrite conditions and rules to send them to the www. version if they try to access it without that but everytime I do that an error occurs. The only rewrite rule I have is below and Server_Name is set to www.my_domain_name.com at the top of the .conf file. Can you help me write a rewrite rule to always send them to the https version and to the www. version or give me advice on how to get the non www. version to serve up the proper page with https? Also it is worth noting that when I try to open the non www. version in my browser it works fine, but when a first time user trys it it does … -

If such event occurs JS sends message to Channels where it gets access to db where there is a model of a counter, increment it depends it was click or key, and then send it back to group on layers. Unfortunately, error occurs. Why it calls contex error if I already used database_sync_to_async My consumers.py : from channels.generic.websocket import AsyncWebsocketConsumer import json from channels.db import database_sync_to_async from .models import Licznik class MyConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_group_name = 'main_room' self.counter = await database_sync_to_async(self.get_counter)() await (self.channel_layer.group_add)( self.room_group_name, self.channel_name ) await self.accept() def get_counter(self): return Licznik.objects.all()[0] async def receive(self, text_data): if text_data == "klik": self.counter.klik +=1 elif text_data == "klak": self.counter.key += 1 await database_sync_to_async(self.counter.save()) #error here klik = self.counter.klik klak = self.counter.key await (self.channel_layer.group_send)( self.room_group_name, { 'type': 'chat_message', 'klik': klik, 'klak': klak } ) async def chat_message(self, event): message_klik = event['klik'] message_klak = event['klak'] await self.send(text_data=json.dumps({ 'klik': message_klik, 'klak': message_klak })) async def disconnect(self, close_code): await (self.channel_layer.group_discard)( self.room_group_name, self.channel_name ) await self.close() Error: Exception inside application: You cannot call this from an async context - use …
