pythonanywhere django static files are not collected from application
The problem is that static files from Django app are not being collected in pythonanywhere. After the command python manage.py collectstatic In the directory /home/user/user.pythonanywhere.com/static Only the admin folder appears. settings.py: STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'myapp' ] Css file location: +---myapp | +---static | | \---myapp | | \---css | | \---myapp.css When I run the command python manage.py collectstatic in my local command line, static files from the application are collected, the problem is in pythonanywhere. All actions are standard, I did everything strictly according to the guide, I cannot understand what's the matter. Thanks a lot I have read all the articles on this topic on pythonanywhere and everything I found on stackoverflow and in the documentation, but nothing helps to solve the problem. https://help.pythonanywhere.com/pages/DjangoStaticFiles https://help.pythonanywhere.com/pages/DebuggingStaticFiles/ https://help.pythonanywhere.com/pages/StaticFiles -
How to dynamically update a django form field queryset based on selection in previous field?
I currently have the following form and view: class CreatePreferenceForm(Form): object_1_type = ModelChoiceField(queryset=ContentType.objects.filter(model__in=['course', 'baseuser'])) object_1 = ModelChoiceField(queryset=Course.objects.all()) object_2_type = ModelChoiceField(queryset=ContentType.objects.filter(model__in=['course', 'timeblock'])) object_2 = ModelChoiceField(queryset=Course.objects.all()) class CreatePreferenceView(LoginRequiredMixin, FormView): template_name = 'crud/create_preference.html' form_class = CreatePreferenceForm success_url = '/crud/create-preference' What I want to achieve is: When the user selects the Course model in the object_1_type field, the object_1 queryset should be updated to be Course.objects.all(). Inversely, if they choose the BaseUser model, the queryset will be BaseUser.objects.all(). Equivalent logic will be applied to the second pair of fields, although with different models. I've researched this for some time and was able to find a few potential approaches, however, I am still struggling with implementing them. Advice or alternative approaches would be greatly appreciated. Potential Approaches: Use an Ajax call to update the frontend to filter out the portions of the queryset you do not want (so I'd start with having the queryset be both models and then remove all instances of the "wrong" model using Ajax). I haven't worked with Ajax before, so I'm unsure on how I would write this. Django form fields can be updated programmatically and it's theoretically possible to achieve what I'm looking for by updating the fields during … -
Django Docker How to only migrate in Container?
Question can be little unclear so let me explain. I have a Django Project and for this time I wanted to use Docker. So I dockerized my project from the tutorials on the internet. As Django users know, if you want to extend the user model you need to make migrations afterwards you edit the model So I was editing my custom user model and wanted to test a feature for my model. What I wanted to achieve was, test migrated version of my Django app on Docker container and if it fits my needs I would make the migration on local files. But after I ran the docker-compose exec web python manage.py make migrations users command my also local files changed. So my question is, if I want to test a feature on migrated version of my app can I test it on Docker container and then migrate on local machine? or did I not understand the logic of docker? docker-compose.yml version: '3.8' services: web: build: ./app command: python manage.py runserver 0.0.0.0:8000 volumes: - ./app/:/backend/ ports: - 8000:8000 env_file: - ./.env.dev depends_on: - db db: image: postgres:13-alpine volumes: - postgres_data:/var/lib/postgresql/data/ environment: - POSTGRES_USER=admin - POSTGRES_DB=db - POSTGRES_PASSWORD=password volumes: postgres_data: -

Django load wrong template
I am new to Django. I am trying to configure an app called 'faq', and an index page to display the different "apps", including the previous one. I was following the Learn Django site guide to decide what was best for the template structure. So, I configured myproject/settings.py to let load the template from templates folder: 'DIRS': ['templates'],. In the app folder myproject/apps/faq I have created a templates folder. In the app views myproject/apps/faq/views.py I defined the views to load the data from database and send it back to the template: from django.shortcuts import render from .models import * def faqs_view(request): faqs = FrequentAskedQuestion.objects.all() context = { 'faqs': faqs } return render(request, 'index.html', context) def faq_view(request, id): faq = FrequentAskedQuestion.objects.get(id=id) print(faq) context = { 'faq': faq } return render(request, 'detail.html', context) In the app folder I have created a URLconf configuration in myproject/apps/faq/urls.py: from django.urls import path from .views import faqs_view, faq_view urlpatterns = [ path('', faqs_view, name='faq-list'), path('<int:id>', faq_view, name='faq-detail'), ] A parenthesis here, since the first attempt I have tried to create a project templates folder and use the project views.py and urls.pyand it didn't work I decided to create another app called main.

celery task scheduled differently?
I have a scheduled Celery task that fetches some data via an API, every 30 min. However, if it crashes or there's no new data, I want the task to retry 5 more times and then stop completely, i.e.(it shouldn't execute after every 30 min anymore).

Manually set model fields in ModelForm
I have a model with a foreign key and a unique constraint as follows: class Menu(models.Model): tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE) name = models.CharField(max_length=128) date_menu = models.DateField() class Meta: constraints = [ models.UniqueConstraint(fields=['tournament', 'name', 'date_menu'], name="unique_name_menu") ] I would like to create a form to add instance of Menu.

As a result I get an integrity error when calling the save function in the view. The question is : how can link the Menu instance created by the form … -

But when I try to save/patch any User data of a User that already has a comment, I get the IntegrityError. users\models.py: class User(AbstractBaseUser): created_at = models.DateTimeField(auto_now_add=True, editable=False)) .... #nothing special here comments\models.py: class Comments(models.Model): created_at = models.DateTimeField(auto_now_add=True, null=True, blank=True, editable=False) modified_at = models.DateTimeField(auto_now=True, editable=False) created_by = models.ForeignKey(User, null=True, editable=False, related_name='%(class)s_created', on_delete=models.SET_NULL) modified_by = models.ForeignKey(User, null=True, editable=False, related_name='%(class)s_modified', on_delete=models.SET_NULL) type = models.CharField(max_length=50, blank=True, default='') content = models.CharField(max_length=100, blank=True, default='') owner = models.ForeignKey(User, null=True, blank=True, related_name='comments', on_delete=models.SET_NULL) The Trace in the Error Message points to the line cmnt.save() in the function update in the users\serializers.py, looking like this: def update(self, instance, validated_data): info = model_meta.get_field_info(instance) #extract nested user information to handle those separately ... ... comments_data = validated_data.pop('comments', None) ... ... # update user fields # Simply set each attribute on the instance, and then save it. # Note that unlike `.create()` we don't need to treat many-to-many # relationships as being a special case.

Renaming the field or using the right filter with django
I accidentaly named one of the fields "type" with django. Is there a way to rename it or can I still use the filter for that 'type' I understand that 'type' is a built-in function and it tries to use it and gives me errors. class Product(models.Model): name = models.CharField(max_length=60) type = models.ForeignKey(CarType, on_delete=models.DO_NOTHING, null=True, blank=True) year_released = models.PositiveIntegerField(default=0) description = models.TextField(null=True, blank=True) price = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True) manufacturer = models.CharField(max_length=60,null=True, blank=True) def get_absolute_url(self): return reverse('product-detail', kwargs={"id": self.id}) class HydrogenView(ListView): model = Product queryset = Product.objects.filter(type='Hyrdogen') context_object_name = 'product' template_name = 'Hydrogen.html' -

When a new model object is create, populate one of the values
I have tried this a few ways but am stuck and unsure where to go. My model (ExampleModStack) has a toadd_fk which is a foreign key obtained from a API. I want to use this to create a forign key refernce to the Toadd model when the ExampleModStack is created. I create ExampleModStack model by reading the API values so I need a funciton to do this for me. I was thinking of using signals pre_save function so that I can set the toadd relationship there. Here is my code: class ExampleModStack(models.Model): toadd_fk = models.IntegerField() toadd = models.ForeignKey( Toadd, null=True, on_delete=models.CASCADE, related_name='%(class)s_toadd' ) class Meta: verbose_name = 'example_mod_stack' verbose_name_plural = 'example_mods_stack' def __str__(self): return str(self.id) @receiver(pre_save) def referenc_product(cls, instance, **kwargs): cls.toadd = Product.objects.get(id=cls.toadd_fk) I can not get this to work though. Does anyone know a way to make this functional?
