Django static files don't load in Heroku
I've been hitting my head against the wall with this one. I am trying to deploy a django app to Heroku but css files are not being loaded. What should I do? I get this error message in console Refused to apply style from 'https://sleepy-wildwood-57073.herokuapp.com/static/network/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. Aside from that heroku logs --tail doesn't seem to show any errors. My settings.py: STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'network/static'), ) TEMPLATE_DIRS = ( os.path.join(BASE_DIR, 'templates'), # Add to this list all the locations containing your static files ) STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage' django_heroku.settings(locals()) MIDDLEWARE = [ 'whitenoise.middleware.WhiteNoiseMiddleware', ... ] One thing is that I am writing styles with scss and then turning them into css with django-sass script. I am not commiting the css files to the repo. Just the scss files. And the page loads, the js scripts load but all the styles won't load! I have no idea what I should do. Please help!

ManyToMany vs. Intermediary Model for Follower-Following Relationship for Django Rest Framework
I'm working on a blog application with Django Rest Framework (very original I know) and I'm trying to add a followers/following relationship between Users. Currently my UserProfile is implemented as follows: from django.db import models from django.contrib.auth import get_user_model from django.db.models.signals import post_save from django.dispatch import receiver User = get_user_model() class UserProfile(models.Model): """Model For Extending Default Django User Model""" user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile') username = models.CharField(max_length=150, blank=True, null=True) bio = models.TextField(blank=True, null=True) avatar = models.ImageField(blank=True, null=True) def __str__(self): return f'{self.user.first_name} {self.user.last_name}' @property def full_name(self): return f'{self.user.first_name} {self.user.last_name}' @property def posts_list(self): return self.user.posts.filter(author=self.user) @property def comments_list(self): return self.user.comments.filter(author=self.user) @receiver(post_save, sender=User) def create_profile(sender, instance, created, *args, **kwargs): """Automatically Create A User Profile When A New User IS Registered""" if created: user_profile = UserProfile(user=instance) setattr(user_profile, 'username', instance.username) user_profile.save() My goal is to create a way to link UserProfiles via a Follower/Following relationship. My first idea was to create a ManyToMany relationship like the following: followers = models.ManyToManyField('self', symmetrical=False, blank=True) This makes sense to me, since a UserProfile can have multiple followers and follow multiple people. If I want to serialize this model, then I can use something like the following: class UserProfileDetailsSerializer(serializers.ModelSerializer): posts_list = SerializerMethodField(source="get_posts_list") followers = SerializerMethodField(source="get_followers") class Meta: model = … -
Handling File Upload Errors in Django with DO/S3
I'm using django-storages with DO/S3 to upload a file from curl (later to be a Java client): curl -F some_file=@some_file.txt -F name=some_file --referer https://localhost:8000 -k -i https://localhost:8000/file/request Storage backend configured: storages.backends.s3boto3.S3Boto3Storage My model field: some_file = models.FileField('Some file', blank=True, null=True, upload_to=some_file_path) All this is working fine. I can send a POST request with a file and it uploads to the right place. What I'm trying to figure out is error handling. Since I'm relying on a third party CDN (DO) and library (boto3) to seamlessly upload files, how do I handle errors if the upload fails? I searched Django, DO, django-storages, and AWS docs and couldn't find a good answer. I'd like to handle failed uploads in a user friendly manner, but I'm not even sure how to test this scenario either. If I was calling this file upload in a view, handling the errors in a try block would be straight forward. But since this storage backend is only configured in settings to be the repository for all my uploaded files, how do I handle errors? Do I have to write a custom backend? Any help appreciated. -
Django - Would I be able to use template tags for rendering HTML given URL path conditionals?
I have a blog page with the path /articles/. I would like to use conditional statements to reflect HTML renders. For example, my blog uses a paginator for blog posts. The paginator uses a URL query to retrieve the next page of post objects like so: /articles/?page=2 I would like for the next page to stylize the HTML template differently, hence my reasoning for using a conditional statement. Here is my template that I use: {% if request.path == '/articles/' %} # Render HTML only meant for the above path {% elif request.path != '/articles/'%} # Render HTML for paths that are NOT the exact match above, such as pagination URLs, # search querys, categories filtering, etc... {% endif %} My current bug is that I'm only rendering the first statement: if request.path == '/articles/' for everything, even non exact matches. So this URL path: /articles/?page=2 is rendering: {% if request.path == '/articles/' %} when it should be rendering the elif {% elif request.path != '/articles/'%} due to the not equals sign. Is the above possible to do with only HTML template tags? I know I can use urls.py and edit views but I'm using wagtail CMS and playing with … -

Django simple app causes a circular import error, followed by a definition error
I'm having a seemingly simple definition error whereby the class Automation is not defined. I've created a very simple app called automations which seems to have caused a problem despite barely changing it. Note that there's also another app called messages, with a many:many relationship with the new automations. Automations is just an app with this simple models.py file: from django.db import models from accounts.models import Account from messages.models import Message 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) def __str__(self): return self.name And messages is a separate app with this models.py file: from django.db import models from accounts.models import Account # from automations.models import Automation # < FAILS from automations.models import * # < WORKS # from apps.get_model(email_messages, Message) # < FAILS # from django.apps get_model(email_messages, Message) # < FAILS # from django.apps import apps # < FAILS # Automations = apps.get_model('email_messages', 'Messages') # < FAILS 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(Automation) # < PROBLEMATIC LINE def __str__(self): return self.name I initially had this import from automations.models import Automation which caused this … -
Defining the initial values of a ModelForm in Django admin using the contents of the request
I'm trying to pre-fill a ModelForm for the admin interface of my Django application. I'm storing some values in request.session and I'd like to use them to define the initial parameter of my ModelForm. I'm able to retrieve these values in ModelAdmin.render_change_form(self, request, context, *args, **kwargs), but I'm not sure how to pass them to the form. Is it possible to do this? I guess I should use a class factory (taking inspiration from this answer) but I'm not sure where to call it, as ModelAdmin.form is a class attribute, not an instance attribute. Below is a short version of the code I'm using. ## admin.py @admin.register(Game) class GameAdmin(admin.ModelAdmin): # ... # This is where I'd like to pass the value of request.session["prefill_data"] form = GameAdminForm() # inherits forms.ModelForm() def render_change_form(self, request, context, *args, **kwargs): self.change_form_template = 'my_app/admin_game.html' extra_context = {} if "prefill_data" in request.session: # I'm able to access this data here extra_context["something_available_for_the_template"] = something_i_did_with prefill_data # Once I've done what I need I can safely delete the session variable del request.session["prefill_data"] return super(GameAdmin, self).render_change_form(request, context | extra_context, *args, **kwargs) # This is actually the view that populates request.session def admin_prefill(self, request): # [something something] request.session["prefill_data"] = foo # … -
Django Channels: Saving logged in user to session
According to the docs: If you are in a WebSocket consumer, or logging-in after the first response has been sent in a http consumer, the session is populated but will not be saved automatically - you must call scope["session"].save() after login in your consumer code: However, I am having some trouble implementing this. I start by getting my user: def login(form_data): try: user = User.objects.get(username=form_data['username']) except User.DoesNotExist: return "This account doesn't exist." password = form_data['password'] if check_password(password, user.password): return user else: return "Incorrect Password." And then following the directions like so: user = login(form_data) async_to_sync(login)(self.scope, user) self.scope["session"].save() self.send(text_data=to_json({ 'operation': 'set_user', 'success': True, 'message': "Loading User Data", 'object': {'username': user.username} })) And it works to deliver the user to the page and set it up for the life of the consumer. However, it seems that the user is not being saved to the user's session, because when I reload the page, self.scope['user'] once again returns an AnonymousUser object. This is how I've got my asgi.py set up: application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AuthMiddlewareStack( URLRouter( routing.websocket_urlpatterns ) ), }) Likewise, navigating to other pages confirms that I am indeed not logged in. What could I be missing? -

Django Lambda with Microservices, Breaking Django Project in Lambda functions

ValidationError getting thrown when cascading the deletion of an object
A user always has one default dashboard for each company they are associated with. We prevent the deletion of the last dashboard/ default dashboard by using the below. @receiver(pre_delete, sender=Dashboard) def check_if_default(sender, instance, **kwargs): if instance.is_default: raise ValidationError( 'Default dashboard for a company can not be deleted.') However with this code in place the users can't be deleted as Django tries to cascade this to the model and it raises this ValidationError. Is there some way to prevent this check or to check in the check_if_default if the user is beeing deleted? -
