The drop-down list when hovering over the element field when the contents of the line is long? (Django-Select2)
Good day! I have data to display in a row. I use such an element as a choice in a drop-down list. I have a very large long line of about 100 characters and I would like to have line breaks. I plan to display a drop-down list in a form. I read that you can come up with something like this - shorten the line - the number of words, characters and make the end of the list in the form of three dots. And when hovering or selecting an element, open something like tooltips with the full name of the content when hovering. Is it possible to do something similar through such add-ons as?

django deploy on pythonanywhere, unhandled-exception error
I'm looking for help since I'm stuck with the deploy (for testing) of my django website. First deploy ever, so expect inaccuracies.

Using Openlayers GeoTIFF sources in a django app
I have a django app with a page that displays OSM through Openlayers, I dynamically add some markers to it and now I also want to display raster overlays from .tif files. I am struggeling to implement Openlayers GeoTIFF. This is my current testing template, where i am just trying to get any tif file to display. I am using a local copy of the openlayers code here: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Title</title> <link rel="stylesheet" href="{% static '/css/ol.css' %}"> <script src="{% static '/js/ol.js' %}"></script> <script type="module" src="{% static '/ol/source/GeoTIFF.js' %}"></script> <script src="{% static '/js/proj4.js' %}"></script> </head> <body id="body"> <div id="map" style="width: 1000px; height: 500px;"></div> </body> <script type="module"> const source = new GeoTIFF({ sources: [ { url: 'https://sentinel-cogs.s3.us-west-2.amazonaws.com/sentinel-s2-l2a-cogs/36/Q/WD/2020/7/S2A_36QWD_20200701_0_L2A/TCI.tif', }, ], }); const layer = new TileLayer({ source }); const map = new Map({ target: 'map', layers: [layer], view: new View({ center: [0, 0], zoom: 12, }), }); </script> </html> This doesnt work because GeoTIFF.js is trying to import from 'geotiff', which it cant find. I know I probably have to go through the npm install and somehow bundle the dependencies to use GeoTIFF in a template like this but I … -
Celery Pytest integration test not working properly with django emails
I made a task for celery and tested it with as a unit with this test: @pytest.mark.django_db def test_document_expiry_alert_unit(settings): settings.CELERY_TASK_ALWAYS_EAGER = True manager = UserFactory( email="manager@mail.com", role=Role.MANAGER, organization__check_docs=True ) doc = EmployeeDocumentFactory(user__organization=manager.organization) mail.outbox = [] document_expiry_alert.delay() assert len(mail.outbox) == 1 sent = mail.outbox[0] html_content = sent.alternatives[0][0] assert manager.email in sent.to assert doc.get_type_display() in html_content assert doc.user.get_full_name() in html_content assert "documents are expiring tomorrow" in sent.body It worked and the test passes, then I tried to make an integration test, so I installed celery[pytest] and add the config in pytest along with the plugin in conftest.py, celery.contrib.pytest Now I tried running this test: @pytest.mark.django_db(transaction=True) def test_document_expiry_alert_intergration(celery_app, celery_worker): manager = UserFactory( email="manager@mail.com", role=Role.MANAGER, organization__check_docs=True ) EmployeeDocumentFactory(user__organization=manager.organization) mail.outbox = [] celery_app.send_task("organizations.tasks.document_expiry_alert") celery_worker.reload() assert len(mail.outbox) == 1 assert manager.email in mail.outbox[0].to But I get this error FAILED tests/organizations/task_tests.py::test_document_expiry_alert_intergration - assert 0 == 1 which means the mailbox has no mail sent, I tried using @patch to mock the send, but I got also zero call counts. The logs and print statements are showing in my terminal when running the test, so everything before the point I send the email, everything works.

accounts/login/ is not mapped when only root paths to its hosted app is not specified
I am using django 5.2.3 and I am trying to use the built-in login system, for that I have defined the path inside my app users/urls.py: from django.urls import path, include from . import views urlpatterns = [ path("accounts/", include("django.contrib.auth.urls")), ] Now the thing is that if I go to the url http://127.0.0.1:8000/accounts/login/ it will throw the following error: The current path, accounts/login/, didn’t match any of these. I fixed the issue by adding the following path to the url dispatcher inside urls.py at the project level (my project/urls.py): urlpatterns = [ path('admin/', admin.site.urls), path('', include('users.urls')) # This fixed the issue ] And now the login form displays correctly at http://127.0.0.1:8000/accounts/login/ HOWEVER, when I tried with a different path, like the following, it doesn't work: urlpatterns = [ path('admin/', admin.site.urls), path('users/', include('users.urls')) # This doesn't work, same error thrown ] My question is, why it does work with path('', include('users.urls')) and not path('users/', include('users.urls')) ?

Could not connect to Saleor during installation. Saleor URL that App tried to connect: http://localhost:8000/graphql/
I'm using self hosted Saleor and trying to integrate self hosted stripe app, however I'm getting "Couldn’t Install Stripe The auth data given during registration request could not be used to fetch app ID. This usually means that App could not connect to Saleor during installation. Saleor URL that App tried to connect: http://localhost:8000/graphql/" I'm not sure why saleor url is http://localhost:8000/graphql/ since all variables in my env point to my deployed server api url and not localhost. Nothing is running locally, i'm using my deployed dashboard to install a deployed stripe app. -

gunicorn gevent CERTIFICATE_VERIFY_FAILED error
I have a Django website running in a Docker container (Debian), which I deploy with the following command: gunicorn core.wsgi:application --bind 0.0.0.0:8000 --workers 33 --worker-class gevent --timeout 1200 I created a simple view with an outgoing request: def my_view(request): import requests requests.get('https://website.domain.com', verify='/etc/ssl/certs/mycert.cer') return HttpResponse('Success') Which throws the error: requests.exceptions.SSLError: HTTPSConnectionPool(host='website.domain.com', port=443): Max retries exceeded with url: / (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1000)'))) What could be the reason for such behavior? What is special about how the gevent worker handles SSL certificates? What I found out for now: The script works fine when I use --worker-class sync or deploy with python manage.py runserver The script works fine when executed via python console or via python manage.py shell (from a running docker container) The certificate is correct (otherwise, it didn't work for cases above) Unsetting REQUESTS_CA_BUNDLE, CURL_CA_BUNDLE, SSL_CERT_FILE or setting them to current location of my cert file doesn't help PYTHONHTTPSVERIFY=0 seems to have no effect verify=False and verify=True have no effect Adding monkey.patch_all() in the script has no effect Adding gunicorn.conf.py with monkey.patch_all() in it has no effect The certificate is definitely being used.

Django media images not loading in production using Nginx , with Debug=False
I'm deploying my Django project with DEBUG=False, and media files like images are not loading.

However, when I access a media file through the browser (e.g., http://<server_ip>/media/sample.jpg), I get a 404 Not Found error. The media files exist in the correct folder, Nginx is running, and permissions are correct. I'm not sure if the issue is with my Nginx config or something else. What did you try and what were you expecting? I tried accessing media files through the browser directly, like: http://<my_server_ip>/media/sample.jpg I expected the image to load, but it returned a 404. I checked that the file exists, the path in Nginx is correct, and the alias points to the right folder. Still, Nginx doesn't seem to serve the media files. -
django-mptt using get_root() on TreeQuerySet element inside for loop and output stored in list does not persist outside of for loop
I am trying to use get_root() on individual TreeQuerySet elements in a for loop. This seems to work in the Django Python shell as shown below. Upon pressing [Enter] twice to indicate the end of the for loop, the result of applying the get_root() to each element is printed automatically in the shell. The result is correct in that the output does indeed list the top level root of each TreeQuerySet element. However outside of the loop, the list in which these should be stored in is not updated. Instead this list contains the original TreeQuerySet elements. In Django Python shell: >>> topics_w_arttype_articles = topics.Topic.objects.filter(to_ArtTypeArticle_topic_from_Topic__title__isnull=False).distinct() >>> topics_w_arttype_articles <TreeQuerySet [<Topic: Level1Topic1>, <Topic: Level1Topic2>, <Topic: Level1Topic3>, <Topic: Level1Topic4>, <Topic: Level2Topic1>, <Topic: Level2Topic2>, <Topic: Level2Topic3>, <Topic: Level2Topic4>]> >>> arttype_topic_roots_list = [] >>> for item in topics_w_arttype_articles.iterator(): ... item.get_root() ... arttype_topic_roots_list.append(item) ... <Topic: Level0Topic1> <Topic: Level0Topic2> <Topic: Level0Topic2> <Topic: Level0Topic3> <Topic: Level0Topic4> <Topic: Level0Topic5> <Topic: Level0Topic5> <Topic: Level0Topic5> >>> arttype_topic_roots_list [<Topic: Level1Topic1>, <Topic: Level1Topic2>, <Topic: Level1Topic3>, <Topic: Level1Topic4>, <Topic: Level2Topic1>, <Topic: Level2Topic2>, <Topic: Level2Topic3>, <Topic: Level2Topic4>] >>> I placed the logic of the shell interaction in a custom template tag, shown below (with additional code that should remove duplicates from the list, if it … -
Why aren't my Django Postgres `ArrayAgg` members sorting?
I'm exploring the use of ArrayAgg and I don't understand why 'histidine-[13C6,15N3]' doesn't occur before 'isoleucine-[13C6,15N1]' in this example: In [25]: for i in Infusate.objects.annotate(tns=ArrayAgg("tracer_links__tracer__name", order_by="tracer_links__tracer__name")).order_by("tns").distinct(): ...: print(i.tns) ...: ['inosine-[15N4]'] ['isoleucine-[13C6,15N1]', 'leucine-[13C6,15N1]', 'valine-[13C5,15N1]'] ['isoleucine-[13C6,15N1]', 'lysine-[13C6,15N2]', 'phenylalanine-[13C9,15N1]', 'threonine-[13C4,15N1]', 'tryptophan-[13C11]', 'histidine-[13C6,15N3]'] The records/rows are sorted based on the first value, which is great, but that first value isn't sorted WRT the other values in the list. For that matter, why doesn't the order of the members of the list change at all when I negate the order_by in the ArrayAgg? According to what I read, this should sort the list items. Am I blind? What am I doing wrong?

How can I display a table in a template with additional category/section rows?
Have a nice day! I have a non-standard table. Which I plan to display in the template. I load the table into the template from the model. And I have additional sections - additional fields. These additional fields characterize - Category, Section, Topics. I am thinking how to display such a table from the model in the template - as shown in the picture. To additionally implement additional fields - categories or sections in the table. I have a rough idea - I have to create a transit model for exactly such a table - in which the number of rows is equal to the number of rows of the original table + plus the number of rows of category sections in addition. That is, there can be about 25 rows of the original table and + plus 6 rows - category sections. In total, the required table will have 31 rows of rows. enter image description here But how to display them in the form as in my picture - separating categories sections? models.py class CreateNewGPR (models.Model): name_object = models.IntegerField(verbose_name="") name_category = models.CharField(verbose_name="") name_working = models.CharField(verbose_name="") type_izm = models.CharField(choices=TYPE_IZMERENIYA, verbose_name="") value_work = models.FloatField(verbose_name="") lyudi_norma = models.IntegerField(verbose_name="") technik_norma = models.IntegerField(verbose_name="") … -
How to support multiple Google Cloud Storage buckets in a Django FileField without breaking .url resolution?
I'm using Django with django-storages and GoogleCloudStorage backend. My model has a FileField like this: raw_file_gcp = models.FileField(storage=GoogleCloudStorage(bucket_name='videos-raw')) At runtime, I copy the file to a different bucket (e.g. 'videos-retention') using the GCS Python SDK: source_blob = default_bucket.blob(name) default_bucket.copy_blob(source_blob, retention_bucket, name) After copying, I update the .name field: recording.raw_file_gcp.name = f'videos-retention/{name}' recording.save() Everything works until I restart the app. Then, when I access .url, Django tries to build the URL using the original bucket from the storage=... argument, even if the file now belongs to another bucket. It ends up generating invalid URLs like: https://storage.googleapis.com/videos-raw/https%3A/storage.cloud.google.com/videos-retention/filename.mp4 I expected Django to keep working even if the file was moved to a different bucket. After debugging, I realized that the FileField is tightly coupled to the bucket used when the model is initialized. If the file moves to another bucket, .url breaks. ChatGPT suggested removing FileField altogether, using a CharField instead, and dynamically resolving the GCS bucket + path in a custom @property using google.cloud.storage.blob.generate_signed_url(). Is there a better solution for this? How can I support multiple GCS buckets dynamically with Django FileField? -
I tried to implement custom validation error in django
I have wrote this validators.py file: from django.core.exceptions import ValidationError import os def allow_only_images_validator(value): ext = os.path.splitext(value.name)[1] print(ext) valid_extensions = ['.png', '.jpg', '.jpeg'] if not ext.lower() in valid_extensions: raise ValidationError("Unsupported file extension. Allowed extensions: " +str(valid_extensions)) This is my forms.py file: class userProfileForm(forms.ModelForm): class Meta: profile_picture = forms.FileField(widget=forms.FileInput(attrs={'class': 'btn btn-info'}), validators=[allow_only_images_validator]) cover_photo = forms.FileField(widget=forms.FileInput(attrs={'class': 'btn btn-info'}), validators=[allow_only_images_validator]) But this error is not showing in my template. The SS is here: Can anybody help me on how do I fix it? -
In Django how can I list a Queryset in one view/template generated by another view?
I'm developing a tracking system that has 2 main datasets Orders and Shipments. Focussing on Orders I want to enable users to enter any combination of field data and then display the resulting list using pagination. To achieve this I have 2 views/templates. One, search_orders, displays a form that is, essentially, a list of the majority of the dataset fields. The other, list_orders, displays a list of the selected orders. This all works fine if I just render list_orders from search_orders without any pagination but, in order to get pagination I (believe that I) need search_orders to redirect to list_orders and, so far, I've been unable to do that. Search_orders view: @login_required def search_orders(request): if request.method == 'POST' and len(request.POST) > 1: orders = Order.objects.all() msg = '' fields_selected = '' for fld in request.POST: if fld == 'orderid' and request.POST.get('orderid'): msg += f'{fld} - {request.POST.get('orderid')} and ' fields_selected = True orders = orders.filter(orderid__icontains=request.POST.get('orderid')) if fld == 'bookingtype' and request.POST.get('bookingtype'): msg += f'{fld} - {request.POST.get('bookingtype')} and ' fields_selected = True orders = orders.filter(bookingtype__icontains=request.POST.get('bookingtype')) if fld == 'shp' and request.POST.get('shp'): msg += f'{fld} - {request.POST.get('shp')} and ' fields_selected = True orders = orders.filter(shp__icontains=request.POST.get('shp')) if fld == 'con' and request.POST.get('con'): msg += …
