Can't add comment with Django forms
I am making an ed-tech app and I want to add comment form for each module in the app. But whenever I try to submit the form it returns 'This page isn’t working' after the submission, and I have tried everything to figure it out, but I couldn't.

DJANGO how to add item to cart? (simple django shop)
I try to build simply Django shop as a code practice. I was wondering how to solve issue of adding items to cart. I must say that i'm interested in simplest solutions since i would like to practice basics before advanced techniques. Thus, i would like to use cart as a model and sth like adding items to query.

Django tests, verify that a Profile is automatically created
thanks in advance, How could I verify that a profile is automatically created after a user creation threw a test? I've searched in the TestCase docs but found nothing but i'm sure I'm missing something really obvious. from django.test import TestCase from django.contrib.auth import get_user_model from users.models import Profile class test_user_creation(TestCase): def test_create_user(self): User = get_user_model() new_user = User.objects.create_user( username="New_user", email="New_user@user.com", date_of_birth="2002-12-23") self.assertEqual(new_user.username, "New_user") self.assertEqual(new_user.email, "New_user@user.com") self.assertEqual(new_user.date_of_birth, "2002-12-23") self.assertIs(new_user.is_admin, False) self.assertIs(new_user.is_staff, False) self.assertEqual( new_user.profile, "New_user Profile") The last one is the one i'm asking about, it's working this way but how could i do it without refering to the string returned by the Profile class ? My Profile class class Profile(models.Model): user = models.OneToOneField( settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def __str__(self): return f'{self.user.username} Profile' -
Django template rendering not giving expected results
I am rendering data from my views into my template, as follows: <tbody> {% for item in lyrics %} <tr class='lyrics-table'> <td>{{item}}</td> <td> {% if item in user_flash %} <p>{{flash}}</p> {% else %} <p>xxx</p> {% endif %} </td> {{item}} works as expected, but {{flash}} only gives the same value for every row, instead of the relevant value.

How to Response PDF and/or ZIP File from Django Rest Framework?
I have a Django Rest Framework API. I have a petition where I send a file in the response, can be PDF or ZIP files. But any of these working. Mi petition is: @api_view(['GET', 'POST']) def getLabels(request,): html = render_to_string( template_name='labels.html', context={}) response = HttpResponse(content_type="application/pdf") response['Content-Disposition'] = "inline; filename=etiqueta.pdf" font_config = FontConfiguration() pdf = HTML(string=html).write_pdf(response, font_config=font_config) if api: r = {'file':pdf,'type':'pdf'} return Response(r, status=status.HTTP_200_OK) Otherwise, if I have two or more labels, I create a Zip: pdf = HTML(string=html).write_pdf(font_config=font_config) files.append((f, pdf)) full_zip_in_memory = generate_zip(files) if api: r = {'file':full_zip_in_memory,'type':'zip'} return Response(r, status=status.HTTP_200_OK) I have some errors: When I response a ZIP: 'utf-8' codec can't decode byte 0xdb in position 12: invalid continuation byte When I response a PDF it answer me that it is null or Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>` I have ridden documentation and request, but I did not find the correct way to answer it in a API.

How to ensure form data is posted correctly in Django
I am populating Django formset with data from Ajax callback (barring a few form elements which are to be filled manually by the user). I am trying to automate filling most of the form elements to eliminate error. However, while "POST"ing, the data does not get saved in respective models. Using the same process I am able to create records (where data is filled (manually) by the user).

Django REST Framework seemingly ignoring field
I'm coming to you, because I think I'm going insane (or maybe I'm just a noob at this), but I'm trying to implement a lobby system in Django, which we can use for a game. For testing purposes, I have set up a private project with Django and threw the Django REST Framework into it. Inside, I have defined a few models, the main one being a Lobby. class Lobby(models.Model): """ We are no lobbyists! """ name = models.CharField(max_length=100) creation_date = models.DateTimeField() creator = models.ForeignKey(User, on_delete=models.CASCADE, related_name='created_lobbies') password = models.CharField(max_length=128, null=True, default="") players = models.ManyToManyField(User, related_name="lobbies") session = models.OneToOneField(LobbySession, on_delete=models.CASCADE, null=True, blank=True, related_name='lobby') Looks pretty simple, is pretty simple. I hooked this model up to a HyperlinkedModelSerializer, which lets it list all fields inside. Players and creators are both realized using PrimaryKeyRelatedFields. Plus the creation_date is filled automatically inside the serializer. The View is a regular ModelViewSet, literally just a few lines long: class LobbyViewSet(RequestLogViewMixin, viewsets.ModelViewSet): """ API endpoint for lobbies """ queryset = Lobby.objects.all().order_by('-creation_date') serializer_class = LobbySerializer permission_classes = [permissions.IsAuthenticatedOrReadOnly] Alright, now for the game's code, we serialize a narrowed down class to a JSON string, like this: {"name":"Horsey from code2","creator":1,"session":null,"players":[1]} Sending that to our API endpoint, returns me … -
Count records per day in a Django Model where date is Unix
I'm trying to create a query that counts how many queries per day there were on a certain Django table. I found a bunch of examples about it but none was dealing with Unix data. Here is what my model looks like: class myData(models.Model): user_id = models.IntegerField() user = models.CharField(max_length=150) query = models.CharField(max_length=100) unixtime = models.IntegerField() class Meta: managed = False db_table = 'myData' So the result i'm trying to get is something like: {'27/06/2020': 10, '26/06/2020': 15 ... } The doubt i have is: should i use a raw MYSQL query or should i use Django's ORM? I tried to make it with a raw query, but didn't get the expected output: select FROM_UNIXTIME(`unixtime`, '26.06.2020') as ndate, count(id) as query_count from myData group by ndate But it gave the following output: ndate query_count 26/06/2020 1 26/06/2020 1 26/06/2020 1 26/06/2020 1 .... Can anyone help me out on this? It doesn't make the difference whether the query is made with raw mysql or Django ORM, i just need a simple way to do this -

Trying to filter by user group using class based view with django-tables2, can't access self.user
I'm trying to use a class based view using django-tables2 to define the table and template returned based on what group the logged in user belongs to. This is my attempt at doing so: class cases(LoginRequiredMixin, SingleTableView): login_url = '/account/login/' if User.objects.filter(pk=self.request.user.id, groups__name='teachers').exists(): model = Graduation table_class = TeachersTable template_name = 'mysite/teachers.html' elif User.objects.filter(pk=self.request.user.id, groups__name='students').exists(): model = Graduation table_class = StudentsTable template_name = 'mysite/students.html' I think the approach is more or less correct (I've only learned about class based views today), but I am unsure how to access the user id. The relevant parts of this view should only be called when a user is logged in (at least I think) because I'm using the LoginRequiredMixin, so 'self' should exist. The answers I have seen addressing this problem say override get_queryset, but I am reluctant to do that as I think that will break django-tables2. What is the best approach in this case to do what I am trying to do? -

How do i get rid of empty filters in django-filter url path and just leave the ones with an actual value selected?
I'm using django-filters to filter results in my search and when i apply filters it shows all the urls even the ones with no filters applied to them, is there a way to just show only the queries with the filters applied and also if possible show them in human friendly urls especially for foreign key fields which show numbers like http://localhost:8000/?city=1 instead of a human readable value like this http://localhost:8000/?city=Nairobi? here is what are the images and my code. models.py class Employee(models.Model): AVAILABILITY = ( ('Mornings','Mornings'), ('Afternoons','Afternoons'), ('Evenings','Evenings'), ('Nights','Nights'), ('Full-time','Full-time'), ('Part-time','Part-time'), ('Special Occassions','Special Occassions'), ('Emergencies','Emergencies'), ('On-demand','On-demand'), ) EDUCATION = ( ('Primary Level','Primary Level'), ('High School','High School'), ('Tertiary Level','Tertiary Level'), ('Open','Open') ) user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True,related_name='employee_profile') avatar = models.ImageField( verbose_name='profile picture', upload_to='users/employees/avatars', blank=True, null=True ) address = models.CharField(max_length=500, null=True, blank=False) education_level = models.CharField(choices=EDUCATION, max_length=50, blank=False, default=False) verified = models.BooleanField(null=False, blank=False, default=False) account_active = models.BooleanField(default=True,null=False, blank=False) bio = models.TextField(null=True, blank=False) preferred_work_locations = models.ManyToManyField(City) availability = models.CharField(max_length=100,choices=AVAILABILITY,null=True, blank=False) date_of_birth = models.DateField(auto_now=False, auto_now_add=False, null=True, blank=False) def __str__(self): return self.user.first_name + ' ' + self.user.last_name filter.py class EmployeeFilter(django_filters.FilterSet): AVAILABILITY = ( ('Mornings','Mornings'), ('Afternoons','Afternoons'), ('Evenings','Evenings'), ('Nights','Nights'), ('Full-time','Full-time'), ('Part-time','Part-time'), ('Special Occassions','Special Occassions'), ('Emergencies','Emergencies'), ('On-demand','On-demand'), ) EDUCATION = ( ('Primary Level','Primary Level'), ('High School','High School'), ('Tertiary … -

Apscheduler logging in Django project

If i call operate_with_file manually from django shell that works fine. File already exists in a model. What wrongs with this?
