Using field in Trunc's kind property
I use PostgreSQL in my project and have three related models: class Timer(models.Model): start = models.DateTimeField() end = models.DateTimeField() task = models.ForeignKey( Task, models.CASCADE, related_name="timers", ) class Task(models.Model): name = models.CharField(max_length=64) wanted_duration = models.DurationField() frequency = models.ForeignKey( Frequency, models.CASCADE, related_name="tasks", ) class Frequency(models.Model): class TimeUnitChoices(models.TextChoices): DAY = "day", "day" WEEK = "week", "week" MONTH = "month", "month" QUARTER = "quarter", "quarter" YEAR = "year", "year" events_number = models.PositiveIntegerField() time_unit = models.CharField(max_length=32, choices=TimeUnitChoices.choices ) I want to get a start of timespan (day, week - a value of Frequency's time_unit) according to start date (field of Timer). I tried execute next code: task.timers.annotate(start_of=Trunc('start', kind='task__frequency__time_unit')) But Django doesn't accept field in kind argument of Trunc class. Error: psycopg.ProgrammingError: cannot adapt type 'F' using placeholder '%t' (format: TEXT) If I execute a following query in raw SQL: SELECT DATE_TRUNC(schedules_frequency.time_unit, timers_timer.start)::date as start_of FROM public.tasks_task INNER JOIN public.schedules_frequency ON tasks_task.frequency_id = schedules_frequency.id INNER JOIN public.timers_timer ON timers_timer.task_id = tasks_task.id; Everything works as wanted. Is there workaround without using raw SQL directly in the Django project? -

Error after removing slug from Page.promote_panels [Django Wagtail]
I am getting the following error after removing the 'slug' field from Page.promote_panels. I am using wagtail 5.1. KeyError at /admin/pages/add/blog/blogdetailpage/10/ "Key 'slug' not found in 'BlogDetailPageForm'. Choices are: category, classes, comment_notifications, container_size, containerized, content, expire_at, go_live_at, publish_at, search_description, seo_title, site, title."

Possible security risks for the following form submission in Django
I am trying to create the page for a livetime chat app using Django and some Ajax. I have always used django forms, since it is more secure and clean if you are not very familiar with javascript. The below html and views.py don't use django forms, but instead go with the traditional method of using javascript. However, I am concerned that there might be security leaks with this following form, which I copied from another website. I believe I added the csrf token correctly, but is there anything else I need to consider?

Django session id cookie not as expected when requesting from swift
When I use Postman to log a user in I get my csrftoken and sessionid cookies in the response as expected. When I make the same exact request but on my iOS app on the simulator, I get the csrftoken cookie from my response just fine as expected. But I do not get the same sessionid cookie. The cookie I'm getting is named "__cf_bm" with a much longer than expected value. The domain of the sessionid cookie on iOS is also now "cloudflare-ipfs.com", whereas on both Postman and iOS the csrftoken domain is just 127.0.0.1. On Postman the sessionid cookie's domain is also just local host. I never did anything with cloudflare. What could be causing this? -

Django "django-modeladmin-reorder" library does not work for side navigation/nav bar of admin
I have a django project, which contains several models with natural grouping, as well as some off-the-shelf models from install libraries. I am trying to have this natural grouping reflected in the admin hope page, as well as the side navigation (nav bar) of the admin panel. By using django-modeladmin-reorder library, the home page is properly grouped as I want. Though, the nav bar ordering is not working and the models appear in their original order (alphabetically, grouped by the library/file where they are fetched from). I have tried several complex (or more complex than just plugging a library) solutions, such as overriding the nav bar/app list html of django and create other templates and creating custom middlewares. -

What is wrong with the Procfile I use in order to deploy my Django website to Heroku
I've been trying for days now to deploy my django website to heroku. I fixed problems with my requirement.txt file, but the Procfile stills gives me problems. The procfile contains this simple line : web: gunicorn myproject.wsgi Which corresponds to the name of my django project, as it is in my wsgi.py file : import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings') application = get_wsgi_application() The structure of my project is basic : /django_learn /myproject /landing_page /myproject /staticfiles /db.sqlite3 /manage.py /venv310 Procfile requirements.txt runtime.txt The requirements.txt was generated with a pip freeze command, no problems when I push to heroku with git push heroku master. When I use herok open I end up with an application error message.

Get ElasticSearch suggestion based on filtered data in Django
I am using django-elasticsearch-dsl for integrating elastic search. I have an API that returns name suggestions using elastic search suggest feature. It's working as expected but the issue is I can't apply a specific filter. For example, I want to get suggestions for the published products only. #Document class ProductDocument(Document): status = fields.IntegerField() meta = fields.ObjectField( properties={ "is_published": fields.BooleanField(), "full_name": fields.TextField( analyzer=html_strip, fields={ "raw": fields.KeywordField(), "suggest": fields.Completion(), } ), }, ) search = ProductDocument.search() search = search.filter("match", meta__is_published=True) completion = { 'field': "meta.full_name.suggest", 'size': 10, 'fuzzy': {'fuzziness': "auto:4,8"}, } suggest = search.suggest("auto_complete","abc", completion=completion) But it return products with is_published=False. Is there any way to achieve this? -

Django translation.activate not working in middleware
I'm attempting to implement an auto language switcher in Django based on the client's IP address. For testing purposes, I've created a middleware to set the language to French ('fr'). class SetFrenchLanguageMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): user_language = 'fr' translation.activate(user_language) request.LANGUAGE_CODE = translation.get_language() response = self.get_response(request) response.set_cookie('django_language', user_language) print("language set to ", user_language) return response When I access a page, I see "language set to fr" printed in the console, indicating that the middleware is executed. However: The content is still displayed in English, the default language. The URL prefix doesn't change to "/fr/". Could someone help me understand why this isn't working as expected and guide me on how to resolve the issue? -
