Prettier - How to format HTML files as expected, in a Django project
I have difficulties in formatting HTML files as expected. Here are some of them: (1) Expectation (before being saved): After being saved and formatted (not as expected): (2) Expectation (before being saved): After being saved and formatted (not as expected) : (3) Expectation (before being saved): After being saved and formatted (not as expected): My .prettierrc is as follow: { "singleQuote": true, "printWidth": 80, "useTabs": true, "overrides": [ { "files": ["**/*.html"], "options": { "printWidth": 150 } } ] } I feel like the expected ones make the file more readable. Am I missing some configurations in .prettierrc? Thank you -
Django 4.1 Static Files
I recently migrated from Django 3.8 to 4.1 without much issue, but since then, when I have DEBUG=True in my development environment, changes to Static Files are not reflected when refreshing the page, I instead have to reboot my dev environment. All other changes, including template changes and view changes are working as expected, just not static file changes. To fix the template changes issue I updated my templates variable from: { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [BASE_DIR/'templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.request', 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] to: default_loaders = [ "django.template.loaders.filesystem.Loader", "django.template.loaders.app_directories.Loader", ] cached_loaders = [("django.template.loaders.cached.Loader", default_loaders)] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [BASE_DIR/'templates'], 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.request', 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], 'loaders': default_loaders if DEBUG else cached_loaders, }, }, ] Which worked perfectly, however still, changes to my static files are not being served. I have tried disabling my browser cache with no luck. I am using Docker to run the dev environment with Docker Compose. Let me know if you need any other information, wasn't 100% sure what to provide as I have no idea what may be causing it. -
displaying image from sqlite in django
I have a model that has a field of Image profile_picture = models.ImageField(upload_to='clothes_images', null=True, blank=True). I have a function that returns the image URL def image_url(self): if self.profile_picture: return self.profile_picture.url return None but when I display in my template using this code <img src="{{cloth.image_url}}"> I get this error Not Found: /media/clothes_images/1_fSqDIIb.png my image name is 1.png but it changes when I store that and not find that. I want to display each image that stores in my local system. -
Django Schema Reverse Related Objects
I have the following two Django models: class Participant(models.Model): name = models.TextField() sport = models.TextField() bookmaker = models.ForeignKey(Bookmaker, on_delete=models.CASCADE) updated_at = models.DateTimeField(auto_now=True) created_at = models.DateTimeField(auto_now_add=True) class Meta: unique_together = ("name", "bookmaker", "sport") def __str__(self) -> str: return f"{self.name} ({self.sport}) | {self.bookmaker.name}" class BookmakerParticipant(models.Model): sharp_participant = models.OneToOneField( Participant, on_delete=models.CASCADE, primary_key=True, related_name="sharp_participant_match" ) soft_participants = models.ManyToManyField( Participant, related_name="soft_participant_matches" ) updated_at = models.DateTimeField(auto_now=True) created_at = models.DateTimeField(auto_now_add=True) In my schema definition I'd like to access all the BookmakerParticipant objects where the Participant is in soft_participants from the Participants perspective. Thus, I created the following schema: class UnmatchedParticipantSchema(ModelSchema): bookmaker: BookmakerSchema soft_participant_matches: BookmakerParticipantSchema class Meta: model = Participant fields = [ "name", "sport", "bookmaker", "soft_participant_matches" ] However, this creates the following error in Django ninja.errors.ConfigError: DjangoField(s) {'soft_participant_matches'} are not in model <class 'core.models.Participant'>. How do I resolve this? -

Serving static files with presigned URLs
I have a Django application hosted in AWS Lightstail and its static and media files hosted in a S3 bucket. The client is asking me to serve ALL the files (static and media) through AWS's presigned URLs. To my knowledge, presigned URLs are more suitable for media or single files rather than all the website's static files, since every time someone access the website, a new URL is generated for each static file, causing loading delays and misusage of the URLs' expiration time. I suggested to set up CloudFront instead. My question: Is the client's request reasonable? And if so, is there a way to serve these static files in a way that the presigned URLs are not created with every new access to the website? -
Display Image related to a Foreign Key
I have scoured the Internet, ChatGPT, StackOverflow, etc, and cannot find out how to make an image from my AWS S3 bucket (from a foreign key) appear in my template.

How to fix importerror or Pythonanywhere deployment with Python upgrade?
I am using Python 3.8 on my mac and developing an app for more then two years. I am hosting this app on PythonAnywhere because I'm using Sqlite3. Now PA sent me an email that I need to upgrade the system image from Python 3.8 to 3.10. I never done this before so I'm registered a free account and deployed the exactly same app to test the process. I made a new project, virtualenv and installed Python 3.10 and Django 5.0 (tried 3.1 too - this is the version on my Mac). I did all the setting ans setted the wsgi too like many times before in other projects. When I installed all the apps and try to run the site I get this very long error traceback: 2023-12-20 18:37:37,746: Error running WSGI application 2023-12-20 18:37:38,100: ImportError: cannot import name 'SuccessURLAllowedHostsMixin' from 'django.contrib.auth.views' (/home/ruszakmikloseu/.virtualenvs/mpa-virtualenv/lib/python3.10/site-packages/django/contrib/auth/views.py) 2023-12-20 18:37:38,100: File "/home/ruszakmikloseu/.virtualenvs/mpa-virtualenv/lib/python3.10/site-packages/django/core/handlers/wsgi.py", line 124, in __call__ 2023-12-20 18:37:38,100: response = self.get_response(request) 2023-12-20 18:37:38,101: 2023-12-20 18:37:38,101: File "/home/ruszakmikloseu/.virtualenvs/mpa-virtualenv/lib/python3.10/site-packages/django/core/handlers/base.py", line 140, in get_response 2023-12-20 18:37:38,101: response = self._middleware_chain(request) 2023-12-20 18:37:38,101: 2023-12-20 18:37:38,101: File "/home/ruszakmikloseu/.virtualenvs/mpa-virtualenv/lib/python3.10/site-packages/django/core/handlers/exception.py", line 57, in inner 2023-12-20 18:37:38,102: response = response_for_exception(request, exc) 2023-12-20 18:37:38,102: 2023-12-20 18:37:38,102: File "/home/ruszakmikloseu/.virtualenvs/mpa-virtualenv/lib/python3.10/site-packages/django/core/handlers/exception.py", line 140, in response_for_exception 2023-12-20 18:37:38,102: … -

On media screen, swiping over the home-slider doesn't move

Django & DRF: trying to find a way to reuse code for user registration for web and REST api
I have a working Django based web experience that has a CustomUser (AbstractUser) model to remove username and require email as default. I implemented a "register" function within views.py that set is_email_verified to FALSE (which is only set to TRUE by the email verification component). Now, I am creating REST services that could be used by a mobile app. I find the logic for the register function within api/views.py to be very similar to the register function within the views.py supporting the web experience. While I can extract the common code into a common function (and call it from both web and api register functions), is it a bad practice to instead update the web register function as follows (and call it from the POST function within the api/views): web views.py: @api_view(['POST']) @permission_classes([AllowAny]) @csrf_exempt def register(request): if request.method == 'POST': if request.content_type == 'application/json': # registration via API call data = json.loads(request.body) user_form = UserRegistrationForm(data) else: # registration via web user_form = UserRegistrationForm(request.POST) if user_form.is_valid(): new_user = user_form.save(commit=False) new_user.set_password(user_form.cleaned_data['password']) new_user.is_email_verified = False new_user.save() Profile.objects.create(user=new_user) send_email_verification_email(request, new_user) if request.content_type == 'application/json': # API response with token token, created = Token.objects.get_or_create(user=new_user) if created: return Response({'message': _('User registered successfully'), \ 'token': token.key, 'created': … -

Select non-image file in Django ckeditor browser
I previously uploaded a zip file from django_ckeditor, and I want to create a link to that file. So I clicked the "link" button (or Ctrl-K), and then selected the "browse server" button to select my file. However, when I select the file, I see no button to select the file, and the preview pane kept spinning: But when an image is selected, I'm able to select the "Embed image" button: Relative Django setting: CKEDITOR_UPLOAD_PATH = "public/" CKEDITOR_UPLOAD_SLUGIFY_FILENAME = False CKEDITOR_RESTRICT_BY_USER = False CKEDITOR_RESTRICT_BY_DATE = False CKEDITOR_FILENAME_GENERATOR = 'util.func.ckupload_name' CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'full', } } def ckupload_name(fname, request): return f'{uuid.uuid4()}/{fname}' It looks the image functionality, but I'm sure I'm opening this box using the "link" button. Because the files are uploaded to a random folder, I cannot manually enter the link easily. (I verified that if I found the UUID part, I can download the file from web) So the question is: How can I get the link toward the zip file from ckeditor? -

How do I unit test writing to a CSV file?
I am currently writing a test for a django script that writes some audit log entries to a CSV file. The system takes one CSV file, parses its contents, then adds entries based on the selections within, and saves it again once its all done.

Elasticsearch, Searching by extra field in logging
I'm using Elasticsearch with elastic-apm==6.19.0 configured for Django. After logging an error message like logger.exception( custom_logging_message, exc_info=True, extra={ 'status_code': status_code }, ) I can indeed observe the error containing custom_logging_message in Kibana. In Elasticsearch, I can even use Query DSL to view the document which was created by the above logging event. It also holds the data which was passed to the logger using the extra keyword, as follows: "error": { ..., "custom": { ..., "status_code": 500, } } So far so great, but I want to write a query which is based on one of the extra fields. Like: GET _search { "query": { "range": { "error.custom.status_code": { "gte": 500 } } } } But the result is empty. I tried to figure out whether the respective field is indexed, using the following query: GET _my_error_index/_mapping?pretty. The result did indeed not hold the respective field under "mappings". Is this the reason why I could not use it in the search query? And if so, how to I get it indexed? Is it a setting in the elastic-apm package? I am very new to this topic and appreciate any help. Thank you. -

How to get hierarchal results from models
I have hierarchal django model and it looks like this class Organizator(Model): is_active = models.BooleanField() user = models.IntegerField() clas Task(Model): content = models.CharField() task_id = models.IntegerField() parent = models.ForeignKey('self') organizator = models.ForeignKey(Organizator, related_name='control_taks') class Performer(Model): user = models.IntegerField() task = models.ForeignKey(Task, related_name='tasks') from this given model I am going to get following result like this { "user": 1, "is_active": true, "control_taks": [ { "task_id": 2, "content": "test", "performers": [ { "user": 1, "tasks": [ { "task_id": 3, "performers": [ { "user": 3, "tasks": [] } ] } ] } ] } ] } how can I do this? My code does not return expected result so I did not show here. Any help would be appreciated! -
