Django - Generic m2m relation or two m2m relations?
I'm building a Movie database. The thing is each movie can have many producers and many directors. The directors can be either persons or collectives, and the producers might be persons, collectives or institutions (or a mixture of all these things). I also want to store different information for these kinds of entities (persons, collectives and institutions). Furthermore, I need: To have order (director1, director2) is different from (director2, director1) The admin to be able to handle producer/director adding, modifying, etc. from the Movie module. To organize my models I've thought of having a generic m2m relation (inspired in this answer) --only for directors, to simplify: class Movie(models.Model): name = models.CharField(max_length=100) # etc... class Person(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) director_of = GenericRelation('Directorship') class Collective(models.Model): name = models.CharField(max_length=100) number_of_participants = models.IntegerField() director_of = GenericRelation('Directorship') class Directorship(models.Model): movie = models.ForeignKey(Movie, on_delete=models.CASCADE, related_name='directors') content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') order = models.PositiveIntegerField() The problem with this solution is that the Movie admin with a Directorship inline looks awful: I could customize the admin form to display a specific ModelForm depending on the choice of the first combobox, but that looks like an awful lot of work … -

AttributeError: 'module' object has no attribute 'lru_cache' in Apache using Python3
I'm having trouble running my Django application through Apache. Running Django on the built in development server works fine, as does serving html files directly through Apache. I originally had the error 'no module named django.core.wsgi' which I remedied by updating the WSGIPythonHome directive to point to the python3.6/site-packages directory. After doing this from looking at the traceback the server appears able to locate django.core.wsgi but now throws the error: AttributeError: 'module' object has no attribute 'lru_cache' I read it could potentially be a Python2 / Python3 issue with Apaches version of mod_wsgi so I reconfigured Apache and reran make, make install but no luck there. I found the same question posted here: AttributeError: 'module' object has no attribute 'lru_cache' and tried the recommended solution of removing libapache2-mod-wsgi and installing libapache2-mod-wsgi-py3 both system wide and within the virtual environment I'm pointing to in my httpd.conf file. This didn't fix the issue either. What could be the cause ? Help is greatly appreciated !

How can I select two ranges of the same field in Django?
With the following model: class Event(models.Model): latitude = models.FloatField() longitude = models.FloatField() I would like to execute the following logic: Select all events where latitude is in range(float1, float2) or in range (float3, float4) This looks like this in SQL: SELECT * FROM event WHERE latitude (BETWEEN float1 and float2) or (BETWEEN float3 and float4); I tried this in Django but I get a "SyntaxError: keyword argument repeated": Events.objects.filter(latitude__range(float1, float2), latitude__range(float3, float4) -

CSRF verification always fails when accessing Django admin page through nginx proxy
I have gunicorn serving a Django (v3.0.6) project on my server (at port 8000). I have the host name (and variations on localhost) in the ALLOWED_HOSTS variable of my Django project. And I have nginx set up to serve various apps within my Django project via a reverse proxy, like this: location /guestbook/ { proxy_pass http://localhost:8000/guestbook/ ; } These all seem to work just fine, for the record. What isn't working fine is the Django admin app. Initially I set it up with a very simple reverse proxy as shown above, but over time, as I was experiencing problems with it, I started incorporating various suggestions I found online until now it looks like this: location /admin/ { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-NginX-Proxy true; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://localhost:8000/admin/ ; } but my problem persists: If I visit the admin site (via the nginx proxy) remotely after clearing all my cookies, the admin page loads just fine. I type in my login credentials, hit "login" and nothing happens. If I hit login again, the CSRF verification fails, and if I have DEBUG set to True Django says the CSRF … -

Trying to create a dynamic search/filter table for 25 thousand rows of NBA data using Django, Postgresql, and Jquery
But I have no idea what I'm doing. Now this is how far I've gotten: views.py: statsReg = list(seasonstats.objects.filter(pts__gt=2000).order_by('pts')[0:5].values()) stats = simplejson.dumps(statsReg) return render(request, 'djangotest.html', {'stats': stats}) html: <table border="1", id="players", class="text-center"> <tr> <th>Year</th> <th>Player</th> <th>Pos</th> <th>Age</th> <th>Tm</th> <th>G</th> <th>GS</th> <th>MP</th> <th>PER</th> <th>TS%</th> <th>Points</th> </tr> <tbody id="myTable"></tbody> </table> <script> var myArray = {{ stats|safe }}; buildTable(myArray) function buildTable(data){ var table = document.getElementById('myTable') for (var i = 0; i < data.length; i++){ var row = `<tr> <td>${data[i].year}</td> <td>${data[i].player}</td> <td>${data[i].pos}</td> <td>${data[i].age}</td> <td>${data[i].tm}</td> <td>${data[i].g}</td> <td>${data[i].gs}</td> <td>${data[i].mp}</td> <td>${data[i].per}</td> <td>${data[i].tspercent}</td> <td>${data[i].pts}</td> </tr>` table.innerHTML += row } } </script> So this code displays five rows of statistics correctly in a table on my page, but I have a few questions on where to go from here. My first question is if i'm even accessing postgres with this mode.objects call, I've migrated the model to my database and can browse it in psql, but I just don't get how this works. My second question is how I would alter the query by use of a button to for instance, increase the value in the [0:5] part of the query, or change the filter or order. Any comments would be greatly appreciated! -
WSGI: (11) Couldn't create worker thread
I set up an apache2 server running 2 different django projects as virtual hosts using their own subdomain. Both hosts got their own demon WSGI process. However, when I start the apache2 server only one of those 2 projects run properly. Trying to open the index page of project 2 leads to an endless loading try by the browser. So I checked the error.log of apache2 and saw, that it was full of [wsgi:alert] [pid xxxx:tid xxxxxxx] (11)Resource temporarily unavailable: mod_wsgi (pid=xxxx): Couldn't create worker thread x in project2 process project2 It logs this message every 5 sec. or whenever a request for project 2 comes in. That explains, why there is this infinite waiting loop in the browser, but I don't get, why no thread could be spawned. I already looked around the web for a possible solution, but did not find anything helpfull. Most of the findings were either different problems, had no solution or had a solution that was out of date or used files I can't find on my system. Using top I did not find any unexpectedly high usage of CPU or Memory that could explain, why no thread was spawned. I already tried to … -

How do I maintain session across requests in django if I'm using cache / db based session?
I'm implementing a in-memory cache-based session in django: https://docs.djangoproject.com/en/3.0/topics/http/sessions/#using-cached-sessions session_store = SessionStore() session_store['key'] = value session_store.create() but i found that even though the data does persist in memory across multiple requests, but it wont set the session_key in the cookie. Is the intended usage to just pass the key to client and have them send back as a param? right now im manually setting and retrieving the cookie (as request.session['session_key'] doesnt work for me) CREATE response = Response(serializer.data, status=status.HTTP_201_CREATED) response.set_cookie('session_key', session.session_key) RETRIEVE session_key = request.COOKIES['session_key'] -
Stripe does not work correctly - invoice paid but it does not send randomly 'invoice.payment_succeeded' webhook response - bug?
I am using Stripe Webhook and this is phenomenal. I use Stripe webhook in my Django app like this: class StripeView(GenericAPIView): serializer_class = UserNameSerializer def post(self, request): payload = request.body event = None try: event = stripe.Event.construct_from( json.loads(payload), stripe.api_key ) except ValueError as e: # Invalid payload return HttpResponse(status=400) print(event.type) if event.type == 'invoice.payment_succeeded': payment_invoice = event.data.object ... Every single time I use exactly the same method exactly the same way and it is executed without any errors in the same way. It looks like this: customer = stripe.Customer.create( email=user.email, source=request.data['token'] ) subscription = stripe.Subscription.create( customer=customer.id, items=[ { 'plan': 'plan_H8K23228WmaQM', 'quantity': request.data['amount'], }, ], expand=['latest_invoice.payment_intent'], ) Once Stripe generate requests in this way: 2020-06-05 22:48:21 --> payment_method.attached [evt_no] 2020-06-05 22:48:21 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:22 --> customer.created [evt_no] 2020-06-05 22:48:22 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:23 --> charge.succeeded [evt_no] 2020-06-05 22:48:23 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:23 --> invoice.created [evt_no] 2020-06-05 22:48:23 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:24 --> invoice.finalized [evt_no] 2020-06-05 22:48:24 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:24 --> payment_intent.succeeded [evt_no] 2020-06-05 22:48:24 <-- [400] POST http://localhost:8007/stripe/ [evt_no] 2020-06-05 22:48:27 --> customer.source.created [evt_no] 2020-06-05 22:48:27 <-- [400] POST http://localhost:8007/stripe/ [evt_no] Other times he … -
