Django Redirect followed by database lookup
I have an authenticated user that is signed into a webpage Page1.html on this page I want to create redirect the user to another page that matches a particular property that the user has in their user role. I managed to get the part working that redirects the user to that webpage, but I know I am going to be faced with having many users so it will take a while for searching each user that is why I want the second redirect to occur on the second html page. My thoughts are that I use the manipulation of the post to the redirect of the first page Page1.html, and have Page1.html have a please wait till redirected to the final page that they will be using. I was reading this question but it did not really answer my question: Django - show loading message during long processing -

Writing Django Func() Expression with multiple parameters and specify the order
I'm using Func() Expressions to use this answer and compute the difference between two dates in business days: class BusinessDaysBetween(Func): """Implementation of a Postgres function to compute the working holidays between two fields.""" template = """ (SELECT COUNT(*) FROM generate_series(%(expressions)s, interval '1 day') s(day) WHERE EXTRACT(DOW FROM s.day) NOT IN (0, 6)) """ arity = 2 output_field = IntegerField() However, I am having problems with the formatting of Date and DateTime. So I want to call the functions mentioned in this answer. My edited code looked like this: class BusinessDaysBetween(Func): """Implementation of a Postgres function to compute the working holidays between two fields.""" template = """ ( SELECT COUNT(*) FROM generate_series( TO_CHAR(CAST(%(expressions)s AS DATE), 'YYYY-MM-DD'), TO_CHAR(CAST(%(expressions)s[1] AS DATE), 'YYYY-MM-DD'), interval '1 day' ) s(day) WHERE EXTRACT(DOW FROM s.day) NOT IN (0, 6) ) """ arity = 2 output_field = IntegerField() The problem is that I am putting both parameters in the first place, I don't know how to specify the order of the parameters in which they will appear.

Why am I unable to query the date from my database in django?

Do not monitor changes for field in django-simple-history
I am trying to monitor and display historical changes of my model. Problem is that every time user logins it saves it to historical model. I have tried to exclude this field like shown bellow, but it just saves new instance without field last_login.

How to update large amount of records in chunks?
I have models: class Partner(models.Model): sap_code = models.CharField(max_length=64, null=True, blank=True, verbose_name='sap id', default=uuid4) # another fields class DeficienciesAct(models.Model): partner = models.ForeignKey('partners.Partner', null=True, on_delete=models.CASCADE) sap_code = models.CharField(max_length=64, null=True) # another fields Data: Partner: id sap_code 1 123 2 124 ... ... DeficienciesAct: id partner_id sap_code 1 null 123 2 null 333 ... ... ... 500000 null 421 Let's imagine that in DeficienciesAct there are 500 000 records. Not all DeficienciesAct.sap_code can be in Partner.sap_code. So I need to update field DeficienciesAct.partner_id by DeficienciesAct.sap_code. DeficienciesAct.sap_code is equal to Partner.sap_code. For that I developed a script: DeficienciesAct.objects.filter( partner__isnull=True, sap_code__in=Subquery(Partner.objects.values_list("sap_code")) ).annotate( new_partner_id=Subquery( Partner.objects.filter( sap_code=OuterRef('sap_code') ).values('id')[:1] ) ).update(partner_id=F("new_partner_id")) Well that works. But I'm afraid that huge amount of records can affect a database (postgres). Is there any way to do the task in chunks? -
Why is bootstrap able to load the backdrop for one modal but not the other

Custom ASGI worker metrics with OpenTelemetry
Is it possible to create custom open telemetry metrics to calculate the average time a request stays queued in ASGI before execution and also the average queue size per worker? Or if it is not possible by worker just in general in the ASGI server. I tried searching on the internet but I didn't found any example of this use case. ChatGPT suugested me to create a middleware and do it like this: import time from starlette.middleware.base import BaseHTTPMiddleware from opentelemetry import metrics # Create a Meter meter = metrics.get_meter_provider().get_meter("asgi.queue") # Define a histogram for queue time queue_time_histogram = meter.create_histogram( name="asgi.queue_time", description="Time requests spend in the ASGI queue", unit="ms", ) class QueueTimeMiddleware(BaseHTTPMiddleware): async def dispatch(self, request, call_next): request.state.queue_start_time = time.perf_counter() # Request received response = await call_next(request) queue_time = time.perf_counter() - request.state.queue_start_time queue_time_histogram.record(queue_time * 1000) # Convert to milliseconds return response However I am little suspicious about this snippet and don't know if this is exactly what we want. Does anyone have any advice on this case? -

Django-CKEditor5 Source Editing Feature Doesn't Work

Django: How to natural sort a QuerySet with Postgres and SQLite
I have the following model: from django.db import models class VersionInfo(models.Model): version = models.CharField("Version", max_length=16) # 3-digit version like "1.2.3". I have to natural sort the QuerySet by the 3 parts of "version" when rendering a django_tables2 table. I already tried things like this, but it doesn't sort like expected: from django.db.models import Func, IntegerField, Value from django.db.models.functions import Cast class SplitPart(Func): function = 'SUBSTR' template = "%(function)s(%(expressions)s)" def get_queryset(self): qs = super().get_queryset() qs = qs.annotate( major=Cast(SplitPart('version', 1, Func('version', Value('.'), function='INSTR') - 1), IntegerField()), minor=Cast( SplitPart( 'version', Func('version', Value('.'), function='INSTR') + 1, Func(SplitPart('version', Func('version', Value('.'), function='INSTR') + 1), Value('.'), function='INSTR') - 1, ), IntegerField(), ), patch=Cast( SplitPart( 'version', Func(SplitPart('version', Func('version', Value('.'), function='INSTR') + 1), Value('.'), function='INSTR') + Func('version', Value('.'), function='INSTR') + 1, ), IntegerField(), ), ).order_by('major', 'minor', 'patch') return qs Yes, it's very ugly, but should work in SQLite and Postgres (SQLite has no STRING_TO_ARRAY function), but it doesn't. Does anybody have an idea? May be there's a library providing this functionality? Thanks. -
Django + React: Can't get access to an endpoint

What is meant with validation for django imagefield?
The ImageField docu states: Inherits all attributes and methods from FileField, but also validates that the uploaded object is a valid image. Yet any string is accepted class Foo(Model): pic = models.ImageField(upload_to='files') e.g. I can save this without error and nothing is uploaded to files (not even with a correct file) fooinstance.pic="bogus" fooinstance.save() fooinstance.pic.__dict__ {'_file': None, 'name': 'bogus', 'instance': <Foo:...>, 'field': <django.db.models.fields.files.ImageField: pic>, 'storage': <django.core.files.storage.filesystem.FileSystemStorage at 0x721add4903d0>, '_committed': True} Meanwhile the FileField works/uploads perfectly fine -
Securly passing authorization token from template to static javascript in Django

Why does django override css variable name from db?
I'm taking over a django+react project from a guy who left the company, but this is the first time I work with django so I'm somewhat clueless. The project is a status management page with calendar and stuff (sqlite3 as db). Possible statuses (like In Office, or Sick Leave) and their corresponding data is stored in db, including color for the status. The color was previously stored as a css hex string without the # (got prepended later by code). But the color values are used at multiple places, so they were copy-pasted many times. Since the colors might change, I wanted to get them all together, so I created css variables like '--in-office-color: rgb(whatever)', and changed db to contain the strings 'var(--in-office-color)' and so instead. Now when I want to return it in a view like this: class SomeView(APIView): def get(self, request): //... data = { /* other profile data here */ "statuses": {i.id: {"name":i.name, "color": i.color} for i in Statuses.objects.all()} } return Response(data) Then in the response some css variables are ok, and some got changed. The two problematic ones are "--in-office-color" which changes to "--in.office-color" and "--home-office-color" also changed to "--home.office-color" (whilst "--out-of-office-color" remains unchanged for example) … -

I have seen TestCase.setUpTestData which improves test speed quite a bit in my case. I typically prefer pytest fixtures instead of the TestCase classes. However,when I make a session-scope fixture which does data preparation needed for all tests with the fixture, I get RuntimeError: Database access not allowed, use the "django_db" mark, or the "db" or "transactional_db" fixtures to enable it. I followed https://stackoverflow.com/a/72261942/29412366, but that had no effect. How can I store and re-use a DB state within a Django application when testing using pytest? I use an in-memory sqlite3 DB. I tried https://stackoverflow.com/a/72261942/29412366 : @pytest.mark.django_db @pytest.fixture(scope='session') def thing(django_db_setup, django_db_blocker): del django_db_setup # Cannot be used with usefixtures(..) it won't work with django_db_blocker.unblock(): print('sleeping') Thing.objects.create(thing='hello') and expected the test to run successfully + save time. Instead, I got the RuntimeError mentioned above. (function-scoped fixtures work fine, but then I don't save any test execution time) -
Django NFC Writing Issue on Production - HID Omnikey 5422 - "Service not available" Error
I am developing a Django web application to write to an NFC card using the HID Omnikey 5422 reader.
