I am getting a IntegrityError UNIQUE constraint failed for django

pipenv set path of virtual environment in vs code
I'm using visual studio code on windows 10, using python and django. The problem I have is that whenever I create a new virtual environment it takes place on its default folder, I'd like to change it to take place in the address I specify. How can I specify the folder that virtual environment takes place in? So far, I've tried different ways to solve this problem, but none of work for me, this could be because of the system and tools I'm using, I've tried setting the path variables using set command, like: set Path="~/.ven" I also looked for changing the variables of pip and pipenv but I couldn't make it work. I also searched the similar questions on stackoverflow, I couldn't find a proper answer. Also in the documentation of pipenv, I couldn't find the solution. Thanks for reading and your time. -

Add hyperlink to columns in DataTables
Im newbie in using DataTables, I created a webpage that uses client-side processing to load the data. I want to add Hyperlink in my columns using "columns.render" to view the details in entire row where the value of ID/pk corresponds to the hyperlinked text, so that if a user click the Id/hyperlink in ID columns they would be rerouted to a separate page, "VM/Details/(id/pk)". How I fixed this?

Non superusers unable to login and displaying password in admin - Django
In my Django project, I have a custom user class inside models.py of an app called "accounts": from django.db import models from django.contrib.auth.models import AbstractUser from localflavor.br.br_states import STATE_CHOICES class Company(models.Model): id = models.IntegerField(primary_key=True) class Client(AbstractUser): company = models.ForeignKey(Company, on_delete=models.CASCADE, default=0) role = models.CharField(verbose_name='Cargo', max_length=20) city = models.CharField(verbose_name='Cidade', max_length=20) state = models.CharField(verbose_name='Estado', max_length=2, choices=STATE_CHOICES) phone = models.CharField(verbose_name='Telefone', max_length=25) I have this variable set at my settings.py: AUTH_USER_MODEL = 'accounts.Client' But I am only able to login to the platform with a superuser. Non superusers get a wrong username or password (and they are active, I've checked). Also, in the admin page, it is showing the password of the Clients. Btw, I am using POSTGRES. 1) How can I make any user login into the platform (not admin page, but my main platform)? 2) How can I properly store their password and not show it in the admin page? Thank you. -

Django pgettext and format_lazy with raw regex string
As the title says... In Django 3.0 we can do: urlpatterns = [ path(format_lazy("{text_to_translate}", text_to_translate=pgettext("URL", "text_to_translate")), ] For actually translating text in the URL beyond the prefix added by i18n_patterns. However, what about re_path. What's the equivalent, if any, for being able to do: re_path(format_lazy(r"^{text_to_translate}/(?P<...>)/$", text_to_translate=pgettext("URL", "text_to_translate")), Since this is a raw string meant to be lazily compiled by re.compile. -

I want to use the time to again work on my django web app. This time in addition to showing all my customers on the page I want to return the information for a single customer, that I selected on the website. I get the information about all the customers in the databse to show up on the website and when I use print in my views.py I see all the information from the single object. However, it will not show up in my template :( Here is my code (first the model): class PrivateCustomer (models.Model): WEIBLICH = 'W' MANNLICH = 'M' DIVERS = 'D' KEINEANGABE = 'K' GENDER =( (WEIBLICH, 'Weiblich'), (MANNLICH, 'Maennlich'), (DIVERS, 'Divers'), (KEINEANGABE, 'Keine Angabe') ) kundennummer = models.CharField(max_length=5, null=False, primary_key=True) vorname = models.CharField(max_length=30, null=False) nachname = models.CharField(max_length=30, null=False) adresse = models.CharField(max_length=50, null=False) postleitzahl = models.CharField(max_length=5, null=False) stadt = models.CharField(max_length=30, null=False) geschlecht = models.CharField(max_length=3, null=False, choices=GENDER) geburtstag = models.DateField(null=True) telefon = models.CharField(max_length=30, null=True) mobil = models.CharField(max_length=30, null=True) email = models.CharField(max_length=80, null=True) datum = models.DateField(null=False) # def __str__(self): # return self.nachname Then the function in the views.py: def showCustomer(request): if request.method == 'POST': kd = request.POST['kundennummer'] … -
Do a default save rather than override
I have a model that looks like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.CharField(max_length=160, null=True) avatar = models.ImageField(storage=OverwriteStorage(), upload_to=create_user_image_path, validators=[validate_avatar], default="default/avatars/default.jpg") The model also has its default save method overridden to do some logic for the image that's uploaded. However, let's say the user signed up and has no image, so the default image is used instead. So when this happens Profile(user=22).save() I don't want to use the overridden save method because we are using the default image instead, so there's no extra logic needed. Is there a way I can save it normally in the database instead of it going through the overridden save method? -

Django ListView
It's my first time to use ListView and it doesn't work and give me error. I put get_query but they still give me same error. How can I fix the problem? And everytime when I write code in views.py I always used 'def' not 'class'. But could see many people use (and also django documents) 'class' for ListView. So for general render stuffs we use 'def' and for django.views.generic stuffs we use class right? Why they distinguished these two? This is error what I got. ImproperlyConfigured at /search/results ListView is missing a QuerySet. Define ListView.model, ListView.queryset, or override ListView.get_queryset(). urls.py from django.urls import path from django.conf import settings from django.views.generic import ListView, TemplateView from . import views app_name = 'search' urlpatterns = [ path('', TemplateView.as_view(template_name = "search/index.html")), path('results', ListView.as_view(template_name = 'search/results.html')), path('beerlist', views.beerlist, name='beerlist'), path('<int:beerinfo_id>', views.beerinfo, name='beerinfo'), ] views.py from django.shortcuts import render, get_object_or_404, redirect from django.db.models import Q from django.views.generic import ListView, TemplateView from .models import Beerinfo # Create your views here. def index(TemplateView): template_name = 'search/index.html' def results(ListView): model = Beerinfo template_name = 'search/results.html' def get_queryset(self): query = self.request.GET.get('q') object_list = Beerinfo.objects.filter( Q(name__icontains = query) | Q(label__icontains = query) ) return obejct_list index.html <form action="{% url 'search:results' %}" … -

How to properly configure Celery logging functionality with Django?
I use Django and Celery to schedule a task but I have an issue with the logger because it doesn't propagate properly. As you can see in the code below I have configured the Python logging module and the get_task_logger Celery module. import logging from celery import Celery from celery.utils.log import get_task_logger # Configure logging logging.basicConfig(filename='example.log',level=logging.DEBUG) # Create Celery application and Celery logger app = Celery('capital') logger = get_task_logger(__name__) @app.task() def candle_updated(d, f): logging.warning('This is a log') logger.info('This is another log') return d+f I use django-celery-beat extension to setup periodic task from the Django admin. This module stores the schedule in the Django database, and presents a convenient admin interface to manage periodic tasks at runtime. As recommended in the documentation I start the worker and the scheduler that way: $ celery -A capital beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler celery beat v4.4.0 (cliffs) is starting. __ - ... __ - _ LocalTime -> 2020-04-02 22:33:32 Configuration -> . broker -> redis://localhost:6379// . loader -> celery.loaders.app.AppLoader . scheduler -> django_celery_beat.schedulers.DatabaseScheduler . logfile -> [stderr]@%INFO . maxinterval -> 5.00 seconds (5s) [2020-04-02 22:33:32,630: INFO/MainProcess] beat: Starting...
