Getting "Error processing tar file(exit status 1): open /myenv/include/python3.6m/Python-ast.h: no such file or directory" while docker-compose build
So I am pretty new to docker and django. Unfortunately while running the below command on my linux machine which i am connected using my physical windows machine using putty: docker-compose build I am getting an error: Error processing tar file(exit status 1): open /myenv/include/python3.6m/Python-ast.h: no such file or directory 'myenv' is the environment I have created inside my folder. I am getting a container started on port 9000. The app doesn't have anything yet just a simple project so i just expect to see the 'congratulations' screen. I don't know where I am going wrong. My final goal would be to run the docker url in my windows browser and see the screen of docker container. This is my docker-compose.yml file: version: '3' services: web: build: . command: python manage.py runserver 0.0.0.0:9000 ports: - 202.179.92.106:8000:9000 the IP: 202.179.92.106 is my public IP. I did the above binding so as to access the docker container from my windows machine. Would request additional inputs for the port binding as well if correct/incorrect. Below is my Dockerfile: FROM python:3.6.9 RUN mkdir djangotest WORKDIR djangotest ADD . /djangotest RUN pip install -r requirements.txt Please help me out peeps! -

field_name = ordering[0].lstrip('-') throws IndexError: tuple index out of range in DRF rest_framework\pagination.py
I am getting error IndexError: tuple index out of range while using CursorPagination of DRF. my code- class CursorSetPagination(CursorPagination): page_size = 10 page_size_query_param = 'page_size' ordering = '-created_at' class WalletCreditViewset(viewsets.ReadOnlyModelViewSet): authentication_classes = [JWTAuthentication] permission_classes = [IsAuthenticated] pagination_class = CursorSetPagination serializer_class = WalletCreditSerializer def get_queryset(self): queryset = PaymentOrder.objects.filter(user=self.request.user) return queryset The errors comes when the entry in the database table for a particular user cross the value of page_size.

How can I upload new webpages to a django app?
I am quite new to django so I am sorry if I have overlooked something simple. This is my current website: https://www.michealnestor.com I am trying to remake it using react and django, and a lot of it is different, however I want to keep the functionality of being able to run my js apps from the website: https://www.michealnestor.com/projects EXAMPLE: https://www.michealnestor.com/projects/sortingalgorithms/ . I want to be able to upload project folders, with html, css and js in them from the admin page, and then be able to open these projects from my website. I am not sure how to do this though. I have tried manually placing such a folder in a templates folder in my app, and I have managed to use a view to load the html file, but this file can't seem to find the css and js. Maybe I am going about this the wrong way, in any case I would appreciate some guidance! -
I want to make social registration without token validation

how can I install django website on localhost with bash export
I'm new to django programming, I have downloaded the discord website from git hub https://github.com/python-discord/site. I am trying to install this website for the last 5-6 hours. I searched for an answer everywhere, unfortunately I can't find a clear answer. I will write my steps so far: Downloaded the source code Started venv, started new project and then copied all files to the folder. Added conf folder and inside secret.json now i am stuck at 4: Add export DJANGOPROJECT_DATA_DIR=~/.djangoproject (without the backticks) to your ~/.bashrc (or ~/.zshrc if you're using zsh, ~/.bash_profile if you're on macOS and using bash) file and then run source ~/.bashrc (or source ~/.zshrc, or source ~/.bash_profile) to load the changes. I added the line: export DJANGOPROJECT_DATA_DIR=~/Desktop/website/site-main (this is my website folder path) at the end of the .bashrc file. But I get nothing beside: 'source' is not recognized as an internal or external command, operable program or batch file.

Retrieve all related objects of objects in a queryset
Asked another question yesterday. Unfortunately, the answer did not solve the problem so I thought I narrow the question down and ask again. I have a Category model which is hierarchial(using django-treebeard). When I run example_category.get_descendants() the result I get is a MP_NodeQuerySet like the following <MP_NodeQuerySet [<Category: shoes>, <Category: Sneakers>, <Category: laced_sneakers>]> Out of this queryset I want to fetch every product related to each category and display in a view(DetailView). My best bet has been def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["products_in_category"] = Category.objects.prefetch_related( Prefetch("products", queryset=self.object.get_descendants())) return context Which results in the error "Cannot resolve keyword 'category' into field. Choices are: depth, description, id, numchild, path, products, slug, title" I guess I for some reason get the category back and not its products and I don't really know how to solve it. Check out the old question for more context or just ask away! -
Simple django filter is includes all users’ data rather than that of the logged-in user
I’m new to Django and have built a basic filter that does not filter according to the logged-in user’s data but rather all users’ data, which is incorrect. The filter is for an Automation class, which has a many:many relationship with the Message class (and funnily enough the exact same happens with the message filter). Views.py: @login_required(login_url='login') @allowed_users(allowed_roles=['admin', 'customer'], own_account_only=True) def automation_list(request, pk): account = Account.objects.get(id=pk) automations = account.automation_set.all() filter = AutomationFilter(request.GET, queryset=automations) automations = filter.qs context = {'account': account, 'automations': automations, 'filter': filter} return render(request, 'automations/automation_list.html', context) Filters.py: class AutomationFilter(django_filters.FilterSet): start_date = DateFilter(field_name='date_joined', lookup_expr='gte') end_date = DateFilter(field_name='date_joined', lookup_expr='lte') class Meta: model = Automation fields = '__all__' exclude = ['account', 'date_created'] Models: class Automation(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=200) account = models.ForeignKey(Account, on_delete=models.CASCADE) date_created = models.DateTimeField(auto_now_add=True, null=True) messages = models.ManyToManyField(Message, blank=True) def __str__(self): return self.name class Message(models.Model): name = models.CharField(max_length=100) subject = models.CharField(max_length=128) text = models.TextField() account = models.ForeignKey(Account, on_delete=models.CASCADE) date_created = models.DateTimeField(auto_now_add=True, null=True) automations = models.ManyToManyField('automations.Automation', blank=True) def __str__(self): return self.name Why is the filter not just filtering according to the logged-in user? I’d have thought that I’m only passing in the user’s data via this line: filter = AutomationFilter(request.GET, queryset=automations) Thanks -
Getting 504 Gateway Time-out for Django on Ubuntu
I deployed a Django app on Ubuntu 20.04 with Digital Ocean. The app has a Python package called howdoi that does some web scraping of google search results. I upgraded howdoi with pip from 2.0.16 to 2.0.17. Once I did that, the website stopped working and shows this error: 504 Gateway Time-out nginx/1.18.0 (Ubuntu) But if I downgrade the package to 2.0.16 the website works. The issue only happens on the production server. On localhost, the web app works fine. I am not sure what is the correct command to see the errors. I tried this command: sudo journalctl -u gunicorn -f and that returns these logs (I removed UTC times from the logs to make them more readable here): Aug 27 11:00:05 django-s-1vcpu-2gb-nyc1-01 gunicorn[469603]:[INFO] Worker exiting (pid: 469603) Aug 27 11:00:06 django-s-1vcpu-2gb-nyc1-01 gunicorn[469545]:[WARNING] Worker with pid 469603 was terminated due to signal 9 Aug 27 11:00:06 django-s-1vcpu-2gb-nyc1-01 gunicorn[469665]:[INFO] Booting worker with pid: 469665 Aug 27 11:08:10 django-s-1vcpu-2gb-nyc1-01 gunicorn[469545]:[CRITICAL] WORKER TIMEOUT (pid:469665) Aug 27 11:08:10 django-s-1vcpu-2gb-nyc1-01 gunicorn[469665]:[INFO] Worker exiting (pid: 469665) Aug 27 11:08:11 django-s-1vcpu-2gb-nyc1-01 gunicorn[469545]:[WARNING] Worker with pid 469665 was terminated due to signal 9 Aug 27 11:08:11 django-s-1vcpu-2gb-nyc1-01 gunicorn[469920]:[INFO] Booting worker with pid: 469920 I also tried this: … -
Hot to make a user profile view?
Since I am new to django, this is my first time trying to create a user profile. And I don't know how to make a profile view with a link to it.

Django / DRF - Invalid syntax in a Response object
everyone. Sorry for dumb question. I follow this guide: https://www.youtube.com/watch?v=4Uy8NZsUfF0&t=3341s&ab_channel=JayCoding Here I have a Response object: https://youtu.be/4Uy8NZsUfF0?t=3352 return Response('test': self.get_serializer(test, context={'request': self.request}).data, 'last_question_id':last_question) And I get "Invalid syntax" on colons. But in video it works. When I change string to this: return Response(self.get_serializer(test, context={'request': self.request}).data, last_question) It works well. What should I change to make it work? Thank you. -
Persistent slug in Django
In my Django web application, each user has a randomly generated token generated for purposes beyond the scope of this question. This is the relevant Profile model models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE,max_length=30) verified_account = models.BooleanField(default=False) verify_token = models.SlugField(max_length=15, blank=True, null=True, unique=True) def __str__(self): return self.user.username def get_absolute_url(self): return reverse('user:profile', kwargs={'pk': self.pk}) def generate_token(self): #important from django.utils.crypto import get_random_string self.verify_token = get_random_string(length=15) return self.verify_token def save(self, *args, **kwargs): # also important self.slug = slugify(self.user.username) self.generate_token() # issue is here super().save(*args, **kwargs) So basically, whenever a Profile object is created (on the creation of the User model), a token is randomly generated. However, whenever the Profile model is updated, so is the verify_token. Below is the code for my @receiver that handles user creation @receiver(post_save, sender=User) def create_or_update_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) else: instance.profile.save() I have tried to insert the following code below the Profile.objects.create(user=instance) line in order to try and get it to only generate the token when the Profile is created Profile.objects.filter(user=instance).generate_token() But this gives me the following error 'QuerySet' object has no attribute 'generate_token' What is the best way to ensure that the slug is not changed after every update of it's Profile model?

AttributeError: 'NoneType' object has no attribute 'nace_classes'
Hej! I get an the Error: AttributeError: 'NoneType' object has no attribute 'attribute'. There error occurs when I try to save an institution in the django admin area. All other fields work totally fine. The function where I get the error is a @classmethod in my models.py # class StringFactory: @classmethod def construct_string(cls, something) value = set() value2 = set() for klass in something.attribute.all() # here is the error value.add(klass.code_str()) value2.add(klass.some_str()) return " ,".join(value) if I print my something it is None. Therefor the NoneType error. I am new to classes and classmethods. Can anyone help me where I should look whats going wrong and why it can't find my 'something' or why it is None? I call the class in a function in another class in a django admin.py So I guess the error comes from there. # class SomethingForm(forms.ModelForm): def construct_initial_string(self, somethingelse): return StringFactory.construct_string(somethingelse) I am a bit lost with the classes and tried to name all given somethings (something, somethingelse) the same, but nothing changed. If you want I can post more code but it's very much and in different files. Thanks for your help! -

Django Heroku Channels Live Chat Fail
