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. I already tried: With {0} and {1} and it says there is a syntax error. %(expressions)s and %(expressions)s[1] and nothing. With %s, it's raising the "not enough arguments for format string" โฆ -
wrong password when social authentication in allauth
I have been struggling with this for days, I'm a beginner and I don't know how to implement social authentication (authentication by providers) neither in allauth nor in headless-allauth libraries, I have implemented a sign in with providers in reguler allauth, my settings.py SOCIALACCOUNT_PROVIDERS= { 'google': { 'SCOPE': [ 'profile', 'email' ], 'AUTH_PARAMS': {'access_type': 'online'}, 'APP': { 'client_id': '247133284916-r5pu7h3bnee0vbrbem7nhph5ffhkk5ob.apps.googleusercontent.com', 'secret': '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', 'key': '' } }, 'github' : { 'SCOPE': [ 'user' ], 'APP': { 'client_id': 'Ov23liT9Y3rQjzd25rZN', 'secret': '02f816d85ec879da6ddec85d2d169a019fa1084b', 'key': '' } }, 'facebook': {'METHOD': 'oauth2', 'SCOPE': ['email','public_profile'], 'AUTH_PARAMS': {'auth_type': 'reauthenticate'}, 'FIELDS': [ 'id', 'email', 'name', 'first_name', 'last_name', 'verified', 'locale', 'timezone', 'link', 'gender', 'updated_time'], 'EXCHANGE_TOKEN': True, 'LOCALE_FUNC': lambda request: 'en_US', 'VERIFIED_EMAIL': False, 'VERSION': 'v2.4'} } html <a class="social-login Google-login" href="{% provider_login_url 'google' %}"> <span class="G-logo"></span> <span>Log in with Google</span> </a> when I try to sign up with a provider (google for instance) I am signed in and everything is ok, but when I try to reauthenticated in headless-allauth library by entering the password (I am using both) or I try to sign out then sign in by entering the email and password, I always keep getting (the password you specified is not correct.) when I am sure of my google account โฆ -
Why am I unable to query the date from my database in django?
My database does have an item in the collection I want to query, and it returns the price correctly. from django.db import models # Create your models here. class Dollar_price(models.Model): price = models.FloatField() date = models.DateTimeField() def __str__(self): print(self.date) return str("success") The problem is that when I try printing self.date it says it's None. I don't know why this happens, nor how can I solve this. -
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.

django managers vs proxy models

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: 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
I have an endpoint that I made using djangorestframework. The view has a dispatch method for retrieving data from the request and sending it to post method. Endpoint: class Profile(APIView): permission_classes = [IsAuthenticated] data = None def dispatch(self, request, *args, **kwargs): if request.content_type == 'application/json': try: self.data = json.loads(request.body) except json.JSONDecodeError: return super().dispatch(request, *args, **kwargs) else: return super().dispatch(request, *args, **kwargs) I tested this endpoint with 'Authorization': 'Bearer ${token}' header using postman and rest file, and I am getting the data back with status 200. But when I do the same thing in React using axios.post method, the same user is unauthorized. Axios.post: useEffect(() => { axios.post('http://127.0.0.1:8000/user/profile/', { headers: { "Content-Type": "application/json", "Authorization": `Bearer ${token}` }, body: { "username": "Caution1", "password": "Caution123" } }).then(response => {setData(response.data); console.log(data);}); }, []); I have CORS_ALLOW_ALL_ORIGINS and CORS_ALLOW_CREDENTIALS both to True. -

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
I am adding a custom admin page to the Django admin site where the logged in user can open a text file, it is then parsed, and the parsed data is added as a new record in a table using the user's assigned token. Is the below method secure? Is there a better strategy? I've added a custom template: {% extends "admin/change_form.html" %} {% load static %} {% block extrahead %} {{ block.super }} <script type="application/javascript" src="{% static 'js/add_cal_file.js' %}"></script> {% endblock extrahead %} {% block content %} <h1>Add cal file</h1> <div class="mb-3"> <input class="form-control" type="file" id="formFile" accept=".cal" token="{{ request.user.auth_token }}"> </div> {% endblock %} When the user selects a file the following parser in static 'js/add_cal_file.js is called: const parseCal = async (fileContents, token) => { // parses fileContents to postRequest here const response = await fetch("/api/add-calibration", { method: 'POST', headers: {"Content-Type": "application/json", "Authorization": "Token "+token }, body: JSON.stringify(postRequest) }) } The view at /api/add-calibration is protected using @permission_classes([IsAuthenticated]) limiting it to only requests that provide an authorization token -

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) โฆ -

What is pytests equivalent to setUpTestData in Django?
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.

Images not displaying after deploying Django app to Render, but they work locally
Iโve deployed my Django application on Render, and while everything works perfectly locally (including images), the images are not displaying after deployment. The other static files, like CSS and JavaScript, are loading fine, so I believe the issue might be specific to serving media files. Hereโs what Iโve checked so far: MEDIA_URL and MEDIA_ROOT: Iโve configured the MEDIA_URL and MEDIA_ROOT in my settings.py as follows: python Copy Edit MEDIA_URL = '/media/' MEDIA_ROOT = '/mnt/data/media' # Path to Render persistent disk Persistent Disk: Iโm using Render's persistent disk and confirmed that the images are correctly uploaded to the server. File Permissions: Iโve checked the file permissions, and they seem to be correct. However, despite all this, the images are not showing up on the live site.
