Actually i have created my own custom-user (MyUser) in models.py from django.db import models from django.contrib.auth.models import AbstractUser class MyUser(AbstractUser): country=models.CharField(max_length=20) settings.py AUTH_USER_MODEL = 'new_user.MyUser' I created a simple function in views.py to create new users. from django.shortcuts import render,redirect from django.http import HttpResponse from django.contrib.auth import get_user_model from django.conf import settings def save_account(request): MyUser=get_user_model() if request.method == "POST": name=request.POST.get("name") email=request.POST.get("email") password1=request.POST.get("password1") password2=request.POST.get("confirm-password") country=request.POST.get("country") new_user=MyUser.objects.create_user(username=name,email=email,password=password1,country=country) new_user.save() return redirect('/') else: return HttpResponse("404 Not Found") 1.

I just want to know that which option is best to import custom-user in views.py and why? -

one to many or many to many relationship in DJANGO
I wanna try to build a relationship between an employee and an area. Each employee has to visit more than one area and the area depends on the city. I built a relationship between city and area with a foreignkey(many-to-one). I have to add more than one areas to single employee however, I used manytomany relationship between employee and area. At the time of employee registration when I select city from "City" dropdown the list of the area is not altered. All the areas are shown.

Ngnix redirect for Mouseflow to remove Django staticfiles MD5 hash
Mouseflow recordings issue I have an issue with Mouseflow and the way that it displays "recordings". Mouseflow recordings capture and store the mouse movement of users at a particular time, and also the HTML of the page that they were interacting with. However, Mouseflow does not store the associated static assets that the site uses, such as CSS, JavaScript, or image files such as logos, icons etc. - these are loaded again at the time the recording is played back via the Mouseflow admin panel. Django static assets Apart from CMS-generated media (such as uploaded images and documents), Django's static file assets are collected each time there is a new code deployment, and processed to add MD5 hashes to the end of the filename, preceding the file extension. Example static file URL before processing: https://example.com/assets/css/screen.min.css Example static file URL after processing: https://example.com/assets/css/screen.min.87f74c1e97de.css When Mouseflow generates a recording, the HTML refers to the static asset filenames at the time of the interaction. If a recording is viewed at a later date and the static assets have been changed and re-deployed, the filenames will no longer exist. This issue is documented here on the Mouseflow support site. As suggested in the support … -

RESTful API filter data by list of filters
I am creating a RESTful API to return a lot of data. Now I want to filter this data by the selected filters from a list. There are more than 150 options. The user can select the filters link this: My question is, how can I apply those filters without having 150+ if statements.

Using docker secrets without swarm
I recently went trough a nextcloud deployment and I saw at the nextcloud docs that I could use docker secrets without a docker-swarm setup it seems: https://hub.docker.com/_/nextcloud/ -> Docker Secrets Now I have Integrated secrets into my docker-compose file like so: secrets: mariadb_password: file: secrets/mariadb_password.txt services: app: build: .... environment: MYSQL_PWD: /run/secrets/mariadb_password But currently it seems that my application does not use the content of /run/secrets/mariadb_password instead it uses the path to the file and not the content of it. This is how I currently load my mariadb config at my Django application: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'OPTIONS': { 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", }, 'NAME': env.str('MYSQL_DB'), 'USER': env.str('MYSQL_USER'), 'PASSWORD': env.str('MYSQL_PWD'), 'HOST': env.str('MYSQL_HOST'), 'PORT': env.str('MYSQL_PORT'), } } I also have read at the nextcloud docs that: As an alternative to passing sensitive information via environment variables, _FILE may be appended to the previously listed environment variables, causing the initialization script to load the values for those variables from files present in the container. Do I need to write a initialization script myself? If so, is there a pratical example to do this? thanks in advance -
How to retrieve a GenericRelation data using single query in Django
My aim is to retrieve a GenericRelation data using single query & without use of for loop. Example: I have Customer model & Address model from django.contrib.contenttypes.fields import GenericForeignKey, GenericRelation from django.contrib.contenttypes.models import ContentType from django.db import models class Customer(models.Model): name = models.CharField(null=False, blank=False, max_length=255) email = models.EmailField(null=False, blank=False, unique=True) address = GenericRelation(Address) class Address(models.Model): address1 = models.CharField(max_length=255) address2 = models.CharField(max_length=255) content_type = models.ForeignKey(ContentType, null=True, blank=True, on_delete=models.DO_NOTHING) object_id = models.PositiveIntegerField(null=True, blank=True) content_object = GenericForeignKey('content_type', 'object_id') Bellow is the traditional way i archive GenericRelation data result = [] customer1 = Customer.objects.filter(pk=1) customer1_obj = Customer.objects.get(pk=1) address_of_customer1 = customer1_obj.address.all() result.append({'customer_data': customer1.values(), 'address_data': address_of_customer1.values()}) print('---result---', result) ---result--- [{'customer_data': <QuerySet [{'id': 1, 'name': 'Aakash', 'email': 'aakash@g.com'}]>, 'address_data': <QuerySet [{'id': 2, 'address1': 'Flat 1-2', 'address2': 'Road 1-2', 'content_type_id': 18, 'object_id': 1}, {'id': 1, 'address1': 'Flat 1-1', 'address2': 'Road 1-1', 'content_type_id': 18, 'object_id': 1}]>}] But this is not Good solution. Take too much time when ids is in thousands of range. If is there any other way to archive those data. Then please give your solution in comments.. Note: Make sure your query result get customer & address data in one result. without use of for loop. -
django.core.exceptions.ImproperlyConfigured and TypeError: 'module' object is not iterable
I have a very annoying problem. There was an errors in the project I am creating: django.core.exceptions.ImproperlyConfigured: The included URLconf 'My_Site.urls' does not appear to have any patterns in it.
