Trigger Django Action in Wagtail Equivalent
I'm trying to figure out how to trigger a custom Django action in Wagtail. Essentially trying to run a custom function in some way from the UI in Wagtail. I looked into the ButtonHelper / PageButtonHelper helpers, but it looks like that just allows you to navigate to a url. I'm looking for something very similar to Django Actions in Wagtail. Does anyone know if this is possible, or there's some equivalent in Wagtail? Thanks. -
What is the correct way of setting the Action attribute in a Django form

Hello everyone I ran into a problem, made all settings on the server, checked gunicorn, started the project directly with the command gunicorn Superman.wsgi: application --bind 0.0.0.0:8001, the site started, but without static files.

Django error logging only working in debug mode
When getting a django.request error my logging only writes into the log file when running with DEBUG=True. With DEBUG=False nothing gets written. Here is my LOGGING definition: def skip_static_requests(record): if record.args[0].startswith('GET /static/'): # filter whatever you want return False return True LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'require_debug_false': { '()': 'django.utils.log.RequireDebugFalse', }, 'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', }, 'skip_static_requests': { '()': 'django.utils.log.CallbackFilter', 'callback': skip_static_requests, }, }, 'formatters': { 'verbose': { 'format': "%(asctime)s [%(schema_name)s] %(levelname)s [%(name)s:%(lineno)s] %(message)s", 'datefmt': "%Y-%m-%d %H:%M:%S" }, 'simple': { 'format': '%(levelname)s %(message)s' }, }, 'handlers': { 'file': { 'level': 'INFO', 'class': 'logging.FileHandler', 'filename': '/var/log/mylog.log', 'filters': ['skip_static_requests'], 'formatter': 'verbose' }, 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', 'filters': ['require_debug_false'], }, 'null': { 'class': 'logging.NullHandler', }, }, 'loggers': { 'django.security.DisallowedHost': { 'handlers': ['null'], 'propagate': False, }, 'django': { 'handlers': ['file', 'mail_admins'], 'propagate': True, 'level': config('LOG_LEVEL', default='INFO'), }, 'django.request': { 'handlers': ['file', 'mail_admins'], 'propagate': True, 'level': 'ERROR', } } } Anyone who has a clue what could be wrong? My feeling is that it has nothing to do with the LOGGING definition. -

Update django form maintaining expiration time
this is my first post on this life-saving community. I recently started studying django, using 3.1 right now. My main problem is about maintaining a field from a form after the update. Using: form = TodoForm(request.POST, instance=todo) I can see all the fields, except from the expire one in wich i see dd/mm/yyyy (the default from the date picker) At the moment, to take expire field, I use bootstrap_datepicker_plus. Do you need more code to see what I'm doing wrong? Any idea? -

Django: UpdateView for Double Nested Forms
I currently have an error with writing UpdateView for double nested forms. My architecture is comprised of one template containing one form and two formsets. There's a large form for publisher. Someone can then add as many author formsets as they want and as many book formsets to each author as they want. So it looks like: Publisher -> Author1, Author2, Author3, ... Author1 -> Book1, Book2, Book3 Author2 -> Book4 Author3 -> Book5, Book6 Again, this is all listed in one create.html template. I wrote this using CreateView and it works fine. Now with writing UpdateView, I redirect to my html template for the creation of the forms and can correctly populate the form with data for publisher and author. However, when I try to populate the form with the book data, it populates every author instance with the same book instances rather than populate each author instance with their matching book instances. So it looks like: Publisher -> Author1, Author2, Author3, ... Author1 -> Book1, Book2, Book3 Author2 -> Book1, Book2, Book3 Author3 -> Book1, Book2, Book3 My models.py looks like : class Publisher(models.Model): name = models.CharField(max_length=255, unique=True) class Author(models.Model): name = models.CharField(max_length=255, unique=True) publisher = models.ForeignKey(Publisher, on_delete=models.CASCADE) … -

Submiting multiple (unrelated) forms django, ajax same view same page
I'm trying to submit more than four forms in the same view and template in Django, each unrelated to the other. the challenge is that only one form is submitting successfully, while nothing happens to the other forms, Is there a way I can effectively solve this problem without having separate views for each form using ajax or?

Delete records from 2 tables in join with Django ORM
I am using Django and have 2 tables and I want to delete records from the join. These are simplified model definitions: from django.db import models class MyModelA(models.Model): created = models.DateTimeField(null=True, blank=True) class MyModelB(models.Model): modela = models.OneToOneField( MyModelA, on_delete=models.DO_NOTHING, db_constraint=False ) created = models.DateTimeField(null=True, blank=True) If I used SQL, I could write a DELETE statement with a join, which would delete all records that are returned by the join like this: DELETE a, b FROM mymodela AS a INNER JOIN mymodelb AS b ON a.id = b.modela_id WHERE a.created < '<some date>' I would like to use the Django ORM and the delete() method. I could easily write the SELECT equivalent using: MyModelA.objects.filter(mymodelb__isnull=False) .filter(created__lt=<some date>) .select_related("mymodelb") However, when I chain the delete(), only records in MyModelA are deleted and the resulting SQL-query is something like this: DELETE FROM mymodela WHERE mymodela.id IN (<LIST OF IDs in JOIN>) I could of course use a different on_delete action or get the list of ids and delete the records table by table, but I would like to know: is it possible to get a DELETE a, b FROM... statement as shown above? -
How can pass my data into this particular serializer?
I'm currently working with data that looks like: { "events": [] } But, I'd like to transform it to: { "events": "added-to-calendar": [], "confirmed": [] } I've written out a serializer that looks like: class CalendarFeedSerializer(serializers.Serializer): """ Serializer for the Calendar Feed """ added_to_calendar = EventSerializer(many=True, read_only=True) confirmed = EventSerializer(many=True, read_only=True) class Meta: model = Event But, I'm not entirely sure how to pass my data into this Serializer. Here's the ListAPIView that I am working with to achieve { "events": [] }: class CalendarFeedView(generics.ListAPIView): serializer_class = serializers.EventSerializer def get_queryset(self): user = get_user_model().objects.get(id=self.request.user.id) added_to_calendar_events = user.events_in_calendar() confirmed_events = user.events_confirmed() return added_to_calendar_events | confirmed_events But, as you can see, I am using the base EventSerializer that I created to transform this list of Event's. What I want, is to somehow pass added_to_calendar_events and confirmed_events to my CalendarFeedSerializer so that I can have the desired data structure { "events": "added-to-calendar": [], "confirmed": [] } -
