make authenticated and login work for multiple table other then auth User table django?
I have created hostTable model in hostlogin app and I want to use this table for login purpose for that i have created custom authenticate function because default authenticate() was working for auth user table only. Also login() is not attaching current session to the users from hostTable. Although it working fine if I set AUTH_USER_MODEL ='hostlogin.HostTable' but then admin page is not working also this is not acceptable solution because hostTable I will use for teaches login (127.0.0.1:8081/tlogin/) and studentlogin table I will use for student login (127.0.0.1:8081/slogin/) that time how will I use two different table for different login() and authenticate (), for non of these two users I don't want to provide admin access (127.0.0.1:8081/admin/) that's why I am not using auth user table. models.py from django.db import models from django.utils import timezone from django.contrib.auth.models import AbstractUser,AbstractBaseUser,PermissionsMixin from django.contrib.auth.hashers import make_password, check_password class HostTable(AbstractBaseUser): pid=models.AutoField(primary_key=True,auto_created=True) username=models.CharField(max_length=50,unique=True) password=models.CharField(max_length=128) createdtime =models.DateTimeField(default=timezone.now) last_login=models.DateTimeField(default=timezone.now) is_authenticated=models.BooleanField(default=True) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) USERNAME_FIELD = 'username' REQUIRED_FIELDS=['hostname','ownername','password'] def save(self, *args, **kwargs): self.password = make_password(self.password) super(HostTable, self).save(*args, **kwargs) def __str__(self): return self.hostname view.py def hostlogin(request): if request.method == 'POST': form = UserLoginForm(request.POST) if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') print('view',username,password) user = hostTableAuth.authenticate(request,username,password) … -

No output in serializermethodfield()
I defined a serializermethodfield. My problem in displaying the output. When this method exists, the image field is empty for me. But if I delete this serializermethodfield, my image output will be correct. serilizer: class ArticleSerializer(serializers.ModelSerializer): user = serializers.StringRelatedField(read_only=True) image=serializers.SerializerMethodField() class Meta: model=Article fields="__all__" validators=[Checktitle()] def get_image (self , obj ): request=self.context.get("request") if obj.image: image_url=obj.image.url return request.build_absolute_uri(image_url) return None view: class ArticleListview(APIView): def get(self,request): query_set=Article.objects.all() ser = ArticleSerializer(instance=query_set,many=True,context={'request':request}) print(request) return Response(data=ser.data) I wanted to change the url image.

Unable to start Django app, error related to what seems like a circular import?
I'm currently attempting to build my first django app, a resume website. I get this error when trying to start the app. <class 'mainapp.admin.CertificateAdmin'>: (admin.E108) The value of 'list_display[3]' refers to 'is_active', which is not a callable, an attribute of 'CertificateAdmin', or an attribute or method on 'mainapp.Certificate'. This is what I have in my models.py file related to "certificate" (comments included): `class Certificate(models.Model): class Meta: verbose_name_plural = 'Certificates' verbose_name = 'Certificate' date = models.DateTimeField(blank=True, null=True) # When the certificate was earned name = models.CharField(max_length=50, blank=True, null=True) # Name of the certificate title = models.CharField(max_length=200, blank=True, null=True) # Title or description of the certificate description = models.CharField(max_length=500, blank=True, null=True) # Additional details about the certificate is_active = models.BooleanField(default=True)` And this is what I have in my admin.py file: @admin.register(Certificate) class CertificateAdmin(admin.ModelAdmin): list_display = ('id', 'name', 'title', 'is_active') # Display 'id', 'name', and 'is_active' fields ChatGPT has been no help so far, only circular answers to make sure 'is_active' is properly called, I'm not sure it is, it seems like it (I'm sort of a beginner).

Memcached-MemcacheIllegalInputError - Data values must be binary-safe: 'ascii' codec can't encode characters in position 2-5: ordinal not in range(128
I'm doing some tests with memcached on my django project to understand if I can get benefit of it. But I stuck at unicode character caching. I read many article about it but still could not understand how can I make it work. Here is my code block: def cache(request): client = Client("127.0.0.1:11211") cache_key = '123' # needs to be unique cache_time = 86400 # time in seconds for cache to be valid data = client.get(cache_key) # returns None if no key-value pair if not data: print("setting cache") #data contains unicode characters - Throws an error datafromdb = Subject.objects.all() #unicode characters - Throws an error unicodestr="abçüıö" #encoded unicode characters - Working fine encodedunicodestr=str.encode("abçüıö") client.set(cache_key,unicodestr , cache_time) else: print("getting from cache") return HttpResponse(data) So If I use str.encode on text values It works fine and data can be cached. But If I retrieve data from database(postgres) and this data contains unicode memcached throws an error. I'm wondering if is there a way to use str.unicode on my queryset/list etc that returned from database or something else may be. -
Unit Test pipeline - Django Unit tests
I am working on a django project and it has 20+ apps in it which means i have to run tests of 20+ apps which includes 3000+ tests. So I decided to make subjobs in my pipeline and now running 20 jobs for the unit tests on commit. But the issue is that when more than 1 developer commits and tests runs for both, pipeline get stucks. Pipeline runners are registered on a VM of 32 CPU cores and 24 GB of RAM.

Django Rest Framework APIClient login is not working
I have test function to test whether user can login or not. I am using DRF's APIClient and logging in. When I do a get request to a protected API endpoint I get 401 response.

Create superuser in ktor
in django, there's manage.py createsuperuser for creating a user with elevated privileges. For ktor, I have resorted to creating a user programmatically when the app starts, (first checking if the user already exist) Is there a more elegant or standard way of doing this? I assume it would be a similar process in other frameworks, express, flask etc since they don't also have that -
