Heroku: python version problems
I am trying to deploy a Django app on Heroku, but I am having compatibility issues with the requirements.txt file, it specifies "python-3.11.1". According to Heroku's documentation, Heroku stack 22 supports Python 3.11.1. But each time I try to deploy using the Heroku CLI, I get an error message. -----> Building on the Heroku-22 stack -----> Using buildpack: heroku/python -----> Python app detected -----> Using Python version specified in runtime.txt Traceback (most recent call last): File "/tmp/codon/tmp/buildpacks/0f40890b54a617ec2334fac0439a123c6a0c1136/vendor/runtime-fixer", line 8, in <module> r = f.read().strip() File "/usr/lib/python3.10/codecs.py", line 322, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte /tmp/codon/tmp/buildpacks/0f40890b54a617ec2334fac0439a123c6a0c1136/bin/steps/python: line 9: warning: command substitution: ignored null byte in input !

Force login not working with fixtures (Django TestCase)
I'm populating my test db via a fixture, and everything loads fine. However, I'm unable to get either login or force_login to work. User is also in the fixture. When I try to test the first view, it redirects to the login page. class TestUnauthUser(TestCase): fixtures = ['project.json'] @classmethod def setUpTestData(cls): cls.client = Client() # Get User and Login cls.unauth_user = User.objects.get(username='unauth_user') print(cls.unauth_user.pk) #cls.login = cls.client.login(username=cls.unauth_user.username, password=cls.unauth_user.password) cls.client.force_login(cls.unauth_user) # Get Project cls.project = Project.objects.get(slug='test-project') cls.slug_dict = {'slug': cls.project.slug} # Get Task cls.task = Task.objects.get(slug='test-task') def test_login(self): self.assertTrue(self.unauth_user.login) def test_project_view(self): # Project Main response = self.client.get(reverse('customerportal:project', kwargs=self.slug_dict)) self.assertEqual(response.status_code, 403) I'm able to verify that I have the correct user object with: print(cls.unauth_user.pk). So the User exists and is being obtained. But, it's still not logging-in successfully. -
Is there a way to do {% url 'blog' blog[i].slug %} in Django?
I want to make this type of loops: {% for i in length %} where lenth = range(len(blogs)) in views.py. And then into that loop I want to do: <a href="{% url 'single_blog' blogs[i].slug %}"> blogs go from views.py too: blogs = Blog.objects.all() But it shows an error, it says it can't use [i] in this construction. Please let me know, how can I use blogs[i] in Django HTML? Thanks. -
Preserve and display Django form inputs on POST submission
--PROBLEM-- I have created a basic calculator using Django. The app takes some basic form inputs before executing some calculations and returning the outcomes to the user, however I want the user's inputs to remain visible in the form on submission.

Django simplejwt validate token
I am implementing authentication with Django simpleJwt, and have a question. I want to create something with Client's jwt token. I use methods provided from simpleJwt to validate and decode jwt token. class AccountBookAPIView(APIView): def post(self, request): jwt_authenticator = JWTAuthentication() raw_access_token = request.META.get('access_token') validated_token = jwt_authenticator.get_validated_token(raw_access_token) user = jwt_authenticator.get_user(validated_token) However, I doubt that some methods really validate token. So I checked the method's implementation. Below is the code for question. def get_validated_token(self, raw_token): """ Validates an encoded JSON web token and returns a validated token wrapper object. """ messages = [] for AuthToken in api_settings.AUTH_TOKEN_CLASSES: try: return AuthToken(raw_token) except TokenError as e: messages.append( { "token_class": AuthToken.__name__, "token_type": AuthToken.token_type, "message": e.args[0], } ) raise InvalidToken( { "detail": _("Given token not valid for any token type"), "messages": messages, } ) # this class is AuthToken in my opinion. class AccessToken(Token): token_type = "access" lifetime = api_settings.ACCESS_TOKEN_LIFETIME I can't find the point that validate token from Database. It looks like just construction of token for me. Don't I need to check token in the Database(blacklist and outstanding tokens)? Plz help me. Any answer is welcome.

django redirect to subdomain with exact same url
I have a Django website accessible at codewithbishal.com. This is basically a django blog website and all the blog articles are accessible at codewithbishal.com/example/<path> But now I want to completely restructure the website{such that it is accessible at blog.codewithbishal.com/<path>} and I do no want to lose the current SEO therefore I want to configure django redirect such that when someone launches codewithbishal.com/example/<path> through google search search result or directly through link, they are redirected to blog.codewithbishal.com/<path> instead of a 404 page and eventually google will start showing the new links instead of old once. -
Creating a simple multiple users app in Django
So I've created 3 different users: admins, developers, and project managers. When I use the individual signup forms for each of these users and log out, it works, but then I when try to use the login form, it seems to me that it's acting like the signup form. Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I'm not sure how to proceed from here. Here's what I have so far. models.py class CustomUser(AbstractUser): ACCOUNT_TYPE_CHOICES = ( ('admin', 'Admin'), ('developer', 'Developer'), ('project_manager', 'Project Manager') ) account_type = models.CharField(max_length=20, choices=ACCOUNT_TYPE_CHOICES) login and signupviews class LoginView(View): def get(self, request): # Render the login form form = LoginForm() return render(request, 'users/login.html', {'form': form}) def post(self, request): # Get the form data from the request form = LoginForm(request.POST) # Validate the form data if form.is_valid(): # Get the username and password from the form username = form.cleaned_data['username'] password = form.cleaned_data['password'] # Authenticate the user user = authenticate(request, username=username, password=password) # If the user is authenticated, log them in and redirect to the homepage if user is not None: login(request, … -

Django Admin doesn't recognise blank=True in model

How to add data to Django's database by the click of a button using JS and AJAX

Setup logging of Celery in Django correctly - how?
Setting up celery on our production server seems to be more complicated than it should be - and the problem is logging. Our setup is like this: Server is Ubuntu 20.04.5 LTS We run Django 3.2.8 in it's own user and group named "django" The Celery process also has it's own user and group named "celery". Celery is set up as a service and logs to /var/log/celery In celery.py we have set djangoConf pointing to the main settings.py On startup Celery tries to touch a django-logfile and - missing the permissions to do so - returns an error: Dec 16 10:57:27 h2989788 celery[128418]: Usage: celery [OPTIONS] COMMAND [ARGS]...

Unable to install libapache2-mod-wsgi-py3
I am having some issues with wsgi and getting my django api up and running using apache. I think the issue is the mod_wsgi.so. I have already installed libapache2-mod-wsgi, but my venv is configured using python 3.6. Based on my research I think I need libapache2-mod-wsgi-py3. Trying to install with sudo yum install libapache2-mod-wsgi-py3 returns Loaded plugins: extras_suggestions, langpacks, priorities, update-motd amzn2-core | 3.7 kB 00:00:00 No package libapache2-mod-wsgi-py3 available.

Seeing a 500 internal server error with mod_wsgi, apache and django but nothing in the log file. Gunicorn runs without issue
We released some new code that depends on django-tree-queries and are now seeing an internal server error with mod_wsgi. There is nothing in the apache logs and nothing in the django logs. Normally when we have django erors we do see a stack trace in the logs and get an email.

My django form is never valid. Why is this happening?
I have django application where I want user to be able to upload videos. My view looks like this: class CreateVideo(View): def post(self, request): videos = models.Video.objects.all().order_by('-created_on') form = forms.VideoUploadForm(request.POST) if form.is_valid(): print('form is valid') video = form.save(commit=False) video.save() print('video uploaded') else: print('form not valid') context = { 'video_list': videos, 'form': form, } return redirect('index') def get(self, request): videos = models.Video.objects.all().order_by('-created_on') form = forms.VideoUploadForm() context = { 'video_list': videos, 'form': form, } return render(request, 'videos/upload_video.html', context) My form: class VideoUploadForm(forms.ModelForm): class Meta: model = Video fields = ['title', 'description', 'file'] and model: class Video(models.Model): video_id = models.UUIDField( primary_key=True, default=uuid.uuid4, editable=False, unique=True ) title = models.CharField(max_length=50, null=True) description = models.CharField(max_length=500, null=True) file = models.FileField(null=True) created_on = models.DateTimeField(default=timezone.now, null=True) at = models.ForeignKey(at, on_delete=models.CASCADE, null=True) and my template: <div> <form method="post"> {% csrf_token %} {{ form | crispy }} <button>Submit!</button> </form> </div> When I click submit button, I get: form not valid in terminal. I want form to be created, but form is just never valid. Where is the problem? -
How can I add a dyno for my deployed app in Heroku?
I deployed the app for Heroku successfully but when I check status with 'heroku ps' command I receive information that I have no dynos on the app. The app is created in Django. I tried to add a dyno for my app by browser on my account but there is not any option to do that. Is there a possibility that Procfile causes that issue? My Procfile (file without extension) command: web: gunicorn mywebsite.wsgi --log-file - I tried a lot of solutions from the internet and stackoverflow but my problem is still not solved. I would be grateful for any help. -
