How can i find out how to get the right pk?
I'm new to programming and I'm practicing on making a poll app. But im stuck trying to get the percentage of each choice voted, like so: Models.py: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now was_published_recently.admin_order_field = 'pub_date' was_published_recently.boolean = True was_published_recently.short_description = 'Published recently?' class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text Views.py: class IndexView(ListView): template_name = 'posts/index.html' context_object_name = 'latest_question_list' def get_queryset(self): """ Return the last five published questions (not including those set to be published in the future).

Why won't this post request submit a file in Django Tests
I have a test that looks like this: with open('/path/testing_file.txt') as fp: file = fp form = { 'data1': 'text', 'data2': 'text2', 'file': open('/path/testing_file.txt'), } response = self.client.post('/link', form, follow=True) '/link' is connected to a view which prints the POST data: print(request.POST) In my actual site I submit files with an AJAX request, and it works well. However, when attempting to execute this unit test, the file is not submitted. The print statement prints this: <QueryDict: {'data1': ['text'], 'data2': ['text2']}> I tested the output with print(request.body) as well, and the output is messy, but is clear that the file data is getting sent to the request object, as I can see the content of file in the output. However, since my code works by accessing the file through request.POST['file'] already, I don't want to modify the view code to accommodate a test. So why isn't this working, and how can I properly post a file in django tests? -

How to test successful token claim with jwt
I'm using django rest simple jwt and I wanted to test a simple login and check the response data for the token and other custom data. So I tried with the APITestCase to create an user and then try a login with the same credentials. The results is a 401 instead a 200 with a token in response data. Here is my test case simplified: from rest_framework.test import APITestCase from django.contrib.auth import get_user_model # Create your tests here. User = get_user_model() class UserAuthTestCase(APITestCase): username = "someuser" password = "1234pass" def setUp(self): self.user = User.objects.create( username=self.username, password=self.password ) def test_successful_login_gives_200(self): response = self.client.post( '/auth/token/', { 'username': self.username, 'password': self.password }, format='json' ) self.assertEqual(response.status_code, 200) The the rest framework configuration is set to use the simplejwt authentication only.

Multiple POST to One Endpoint Django
I have an endpoint /homepage in my django app that renders an HTML page. This page has several forms that each make a POST request to the /homepage endpoint. How can I decipher which POST request is being sent to the /homepage endpoint? Or, is it better to make and endpoint like /api that has sub-endpoints for each of the POST requests in the page?

Djano first project search issue
This is the part of the project I'm stuck on: Search: Allow the user to type a query into the search box in the sidebar to search for an encyclopedia entry. If the query matches the name of an encyclopedia entry, the user should be redirected to that entry’s page. If the query does not match the name of an encyclopedia entry, the user should instead be taken to a search results page that displays a list of all encyclopedia entries that have the query as a substring. For example, if the search query were Py, then Python should appear in the search results. Clicking on any of the entry names on the search results page should take the user to that entry’s page. my code: urls.py from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path("wiki/<str:title>", views.wiki, name="wiki"), path("search", views.search, name="search"), ] util.py import re from django.core.files.base import ContentFile from django.core.files.storage import default_storage def list_entries(): """ Returns a list of all names of encyclopedia entries.

Having to run main.py file from manage.py shell django
Running main.py file from manage.py shell django I need some help understanding this. So i have a main.py file that i want to access a file from a database table and do some wizard with numbers in the file. I access this by: import pandas as pd import matplotlib.pyplot as plt from .models import UploadedFile if UploadedFile.objects.filter(the_file='hello.csv').exists(): df = pd.read_csv(UploadedFile.objects.get(the_file='hello.csv').the_file, index_col='Date', parse_dates=True) Thats fine and makes sense. But what i dont understand is when i run this file using: python3 main.py run i get an error. the error says: File "main.py", line 3, in <module> from .models import UploadedFile ImportError: attempted relative import with no known parent package So what i have to do to get my numbers crunched from the file is to go into my python3 manage.py shell and then do from charts app import main. If i do this the code runs as soon as i do that. why is this. i dont understand this. it is a annoying because in pycharm i can't just select the main button and click run. -

Django jinja if-elif statement breaks with ==
So on my front-end, I want to show some HTML only if the user belongs to one of 2 groups: 'admins' or 'clerks'. There are 3 groups of users: 'admins', 'clerks', and 'sellers'. Here is my front-end code: {% if user.groups.all.0 == "admins" %} <h1>Some HTML</h1> {% elif user.groups.all.0 == "clerks" %} <h1>Some HTML</h1> {% endif %} When I run this code, the HTML shows for the admins. But that of the clerks does not show. I have tried printing out the group to be sure that the spelling and the casing were the same, and they were the same. And Django does not throw an error. It only works if I rewrite the code as follows: {% if user.groups.all.0 == "admins" %} <h1>Some HTML</h1> {% elif user.groups.all.0 != "sellers" %} <h1>Some HTML</h1> {% endif %} But I feel like this is not good design. Please am I missing something? Thank you all in advance -

Django filters - adjusting box width
With django_filters, I have my filterset, everything works fine it's just the display that I am stuck with (box width). As you can see below, I have changed the "size" attribute of some of the filter options - because the default is too wide. But the "rating" one, which is a NumberInput, doesn't work for some reason. The "size" attribute works for TextInput but not NumberInput. I want to change the size or rather the width of the NumberInput box that will be displayed in the template (see template pictures below). Can anyone help?

I need to refresh a js file in my static files folder, however whenever I run python manage.py collectstatic, a clone of my static files folder is created in a diffrent part of the project, and the js file is still not updated. I tried changing the STATIC_ROOT variable in the settings.py file to the actual location of my static folder, but it doesn't seem to refresh because the collectstatic warning message in the console says its going to be saved in a completely different location. The Structure of my project is resume_V6-test -resume -home -static (actual location) -resume -settings.py -store -staticfiles (clone of the static folder) -users and my settings.py is # Commented out the location it was before I tried fixing the error #STATICFILES_DIRS = [ #os.path.join(BASE_DIR, "static"), #'/resume_V6-test/resume/home/static', #] #STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_ROOT = os.path.join(BASE_DIR, 'home/static') STATIC_URL = '/static/' And the error message is python manage.py collectstatic You have requested to collect static files at the destination location as specified in your settings: C:\resume_V6-test\resume\staticfiles This will overwrite existing files! Are you sure you want to do this? Thanks -
Django user followers ajax issue
I have built user folloing functionality with Ajax, so a user can follow/unfollow another user. The problem is that when I click "follow" button nothing happens in the frontend. I mean text doesn't change to "Unfollow", as it should be and number of followers does not change too. If reload the page, it is fine - a follower is added. Then if I click "Unfollow" button everything works fine - Ajax request is ok, and in db a follower is deleted. I found out, that the problem happens, because when pushing the "Follow" button and send a Post request, the response code is 500 (Internal Server Error). With "Unfollow" it works fine and the request is 200. I spent a lot of time struggling with this. Any help appriciated. Bellow is the code. The user model and the model for following functionality: from django.db import models from django.contrib.auth.models import AbstractUser from django.utils.translation import ugettext_lazy as _ from django.urls import reverse from django.conf import settings from .managers import CustomUserManager from team.models import Team class Contact(models.Model): user_from = models.ForeignKey('CustomUser', related_name='rel_from_set', on_delete=models.CASCADE) user_to = models.ForeignKey('CustomUser', related_name='rel_to_set', on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True, db_index=True) class Meta: ordering = ('-created',) def __str__(self): return '{} follows {}'.format(self.user_from, self.user_to) … -
