django-channels 1.x detect when user leaves/refreshes page
How can I detect this? Currently I can only do_something if the user clicks a back button and I manually disconnect from the websocket under consideration. Sometimes Websocket DISCONNECT fires, but much of the time it doesn't. If a user refreshes or leaves a page, the disconnect code cannot run. How can I detect when a user leaves/refreshes? -
Callable to add to list_display that references extra field in the intermediary model of a M2M relationship
I have two models, Tender and Status, that have a many-to-many relationship with an intermediary model TenderStatus. TenderStatus has an extra date field which denotes the date on which each status was applied. I want to show all the statuses for each Tender in the list_display. I understand that I have to create a callable in my TenderAdmin class to include in list_display, and although I am able to list out the statuses, I'm having trouble accessing the date field in the intermediary model. Here's an abbreviated version of my models.py: class Tender(models.Model): name = models.CharField( max_length=255, null=False ) tender_status = models.ManyToManyField( 'Status', through='TenderStatus', related_name='tender_status' ) class Status(models.Model): status = models.CharField( max_length=50, null=False ) class TenderStatus(models.Model): tender = models.ForeignKey('Tender', on_delete=models.DO_NOTHING, blank=True, null=False) status = models.ForeignKey('Status', on_delete=models.DO_NOTHING, null=False) date = models.DateField(blank=True, null=False) And here's an abbreviated admin.py--note the status_list callable, this one works but it doesn't have the date in there. Any attempts I've made to access the date have not worked. class TenderAdmin(admin.ModelAdmin, ExportCsvMixin): list_display = ['name', 'status_list'] def status_list(self, obj): return [x.status for x in obj.tender_status.all()] status_list.allow_tags = True I've tried this, but it can't find the date and returns a 500 error: def status_list(self, obj): return [str(x.date) + … -

Custom User model in django. UNIQUE constraint failed: users_user.username
I am trying to make a custom registration form. Main idea is that users should use email as login method and be able to set username in profile(so I dont want to override username field). Problem with built-in django User model is that username field is required so I made my own model based on AbstractUser.

Django urls and views properly defined, still showing 404 error
I have a blog which was running without any error. Different users can register, login, and post articles. Users can write/edit/delete comments on the articles. Previously, the URL of the articles were decided using 'article id'. Later, I read this tutorial and added slug along with id in the URL for every article's Detail View. Then I deleted my old articles since they didn't have any slugs. After this change, a user can create a comment successfully, but cannot 'edit' or 'delete' any comment. Whenever 'edit' or 'delete' button is pressed, 404 error is shown. See the error image by pressing this link.

Django 3.0: Unable to get username in template
I have issue is that in template, I automatically get access of username of Superuser (if that is logged-in) but not username of user based on Buyer (Model). User is getting registered and also can login (I can see it in database). But in template I am unable to get username of user other than superuser. I don't what i am missing here. So i am putting all code of view.py here. Also after user logging he sees bookrepo:home and i am using user logic in header.html (bookrepo:home extends header.html) I have model named Buyer in models.py file. And based on this model, two modelForm has made.

DRF-Filtering with multiple query params and foreign keys
I'm new to Django and I'm trying to create a route that can be called to retrieve an array of vehicles from my database, but I want the user to be able to provide multiple query params in the url (something like: http://127.0.0.1:8000/vehicles/?year=2020&make=Toyota). The problem that I have come across is that my vehicle model includes references to foreign keys for the make and the v_model (so named to avoid conflict with the Django "model"). I have a solution that doesn't seem very graceful. The fact that I have three nested conditional statements for each search field makes me suspicious. I tried using "filters.SearchFilter" but I was only able to provide a single value on which to base the search. So a request like this: http://127.0.0.1:8000/vehicles/?search=2020&search=Toyota would only search for vehicles with a make of "Toyota", ignoring the "year" parameter. Is there some other way to do this that is cleaner or more "Django-approved"? Here is my code: models.py: class Make(models.Model): name = models.CharField(max_length=200, unique=True) def __str__(self): return self.name class VModel(models.Model): name = models.CharField(max_length=200, unique=True) make = models.ForeignKey(Make, on_delete=models.CASCADE) def __str__(self): return self.name class Vehicle(models.Model): make = models.ForeignKey(Make, on_delete=models.CASCADE) v_model = models.ForeignKey(VModel, on_delete=models.CASCADE) year = models.CharField(max_length=5) def __str__(self): return self.year … -

Listing answers for question(get_object_or_404) in for loop. How can I get each answer also as an object in one def?

Reverse Accessor for "CustomPAM.groups' clashes with reverse accessor for 'CustomUser.groups

Both the Models are below. mysite/PAM/models.py from django.db import models from django.contrib.auth.models import AbstractUser from datetime import datetime # Create your models here. class CustomPAM(AbstractUser): date_created=models.DateField(auto_now_add=True) starting_date=models.DateField(default=datetime.now, editable=True) deadline_date=models.DateField(null=True, editable=True) question1=models.TextField() question2=models.TextField() question3=models.TextField() question4=models.TextField() question5=models.TextField() question6=models.TextField() question7=models.TextField() question8=models.TextField() question9=models.TextField() question10=models.TextField() answer1=models.PositiveIntegerField(max_length=1, null=True, editable=True) answer2=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer3=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer4=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer5=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer6=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer7=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer8=models.PositiveIntegerField(max_length=1,null=True, editable=True) answer9=models.TextField(null=True, editable=True) answer10=models.TextField(null=True, editable=True) assessmentFrom = models.EmailField(unique=False) assessmentFor=models.EmailField(unique=False) def __unicode__(self): return self.assessmentFrom and mysite/myusers/models.py from django.db import models from django.contrib.auth.models import AbstractUser from django.conf import settings from django.db.models.signals import post_save from django.dispatch import receiver from rest_framework.authtoken.models import Token class CustomUser(AbstractUser): username=models.CharField(max_length=50, unique=True) name=models.CharField(max_length=150) eagle_id=models.PositiveIntegerField(unique=True, null=True) email=models.EmailField(max_length=150, unique=True) password=models.CharField(max_length=80) is_student=models.BooleanField(default=False) is_professor=models.BooleanField(default=False) is_TA=models.BooleanField(default=False) team_number=models.PositiveIntegerField(default=0,null=False, editable=True) def __str__(self): return self.name #the next four lines are for generating tokens @receiver(post_save, sender=settings.AUTH_USER_MODEL) def create_auth_token(sender, instance=None, created=False, **kwargs): if created: Token.objects.get_or_create(user=instance) the users model is one I made a few weeks ago, the Peer Assessment Model is the … -
What tools do I need to use for a web application [closed]
So I'm teaching my self how to create web applications, like a blog. I'm currently just learning and have built some pages with HTML and CSS(with bootstrap), and I'm using Django.

It would be great if you guys could break it up into categories, like the front-end framework, explain what it does, and give some examples of tools. I know there are groups of tools people use like the ones in MEAN stack, but I really don't get what they do. -
