Django and redis adding :1 to keys
I'm using django-redis to store some data on my website, and I have a problem where Redis is adding :1 at the beginning so my key looks like this: :1:my_key I'm not sure why is it doing this, I've read the documentation on django-redis and I couldn't find anything related, so my guess it has something to do with redis but I can't figure out what. In my settings.py I have the regular: CACHES = { "default": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://xxxxx/0", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } } } And in my tasks.py I set keys like the documentation says: from django.core.cache import cache cache.set(my_key, my_value, 3600) So now I can't get the values using the cache.get(my_key) -

How to solve 'NoneType' object has no attribute 'fields' in Graphene-django
Have this mutation class AddStudentMutation(graphene.Mutation): class Arguments: input = StudentInputType() student = graphene.Field(StudentType) @classmethod @staff_member_required def mutate(cls, root, info, input): try: _student = Student.objects.create(**input) except IntegrityError: raise Exception("Student already created") return AddStudentMutation(student=_student) Before executing the above mutation in graphiql, I add the request header "Authorization": "JWT <token>" so that the user is authorized. But I get the error graphql.error.located_error.GraphQLLocatedError: 'NoneType' object has no attribute 'fields'. The error doesn't occur when I remove the header. It also works fine when I include it in requests for queries. Am I doing something wrong? I need the authorization to happen for mutations too. I tracked the Traceback and it leads to file .../site-packages\graphql_jwt\middleware.py. It appears it's a bug in the package in function allow_any() line 18 field = info.schema.get_type(operation_name).fields.get(info.field_name). New to this I need help. I'm using graphene-django==2.15.0 and django-graphql-jwt==0.3.4 -
Django with django-tenant, unable to perform migrations
Context I am trying to setup django-tenants for my Django application by following the official installation guide. My Django app used to run perfectly fine when I ran manage.py runserver.

How to automatically add repeated data migrations in Django using Djangos ORM?
I am new to Django and have read the basic and advanced tutorial along with some parts of the documentation on migrations and data migrations: https://docs.djangoproject.com/en/4.0/topics/migrations/#data-migrations Also, I have read about fixtures but this seems to be suitable only for initial data provision: https://docs.djangoproject.com/en/4.0/howto/initial-data/#providing-data-with-fixtures The task I want to accomplish is to bulk insert data repeatedly from "outside" in a clean way using using Djangos ORM and all the benefits of migrations. So far, I haven't found a full example on how to do this because using the first option of data migration would require to touch a file everytime I insert/migrate new data. Any hints on how to accomplish this or am I missing something? Thanks in advance! -

Run periodic celery task with a dynamic schedule in django application
I am wondering if it is possible to have my end users dynamically adjust the schedule of a periodic task. So something along these lines: # celery.py def get_schedule(): config = get_user_config() # returns a model object of sorts return config.frequency_in_seconds app.conf.beat_schedule = { 'my_periodic_task': { 'task': 'my_periodic_task', 'schedule': get_schedule, # schedule updated based on `get_schedule` function }, } This way, if a user were to change the frequency_in_seconds field in their user config setting, it would dynamically update the beat schedule. My preference would be to do this outside of the Django Admin site and without any additional packages (e.g. django-celery-beat). Any thoughts or ideas would be much appreciated. Thanks -

Can I override default CharField to ChoiceFoeld in a ModelForm?
I have a (horrible) database table that will be imported from a huge spreadsheet. The data in the fields is for human consumption and is full of "special cases" so its all stored as text. Going forwards, I'd like to impose a bit of discipline on what users are allowed to put into some of the fields. It's easy enough with custom form validators in most cases. However, there are a couple of fields for which the human interface ought to be a ChoiceField. Can I override the default form field type (CharField)? (To clarify, the model field is not and cannot be constrained by choices, because the historical data must be stored. I only want to constrain future additions to the table through the create view). class HorribleTable( models.Model): ... foo = models.CharField( max_length=16, blank=True, ... ) ... class AddHorribleTableEntryForm( models.Model) class Meta: model = HorribleTable fields = '__all__' # or a list if it helps FOO_CHOICES = (('square', 'Square'), ('rect', 'Rectangular'), ('circle', 'Circular') ) ...? -

Conditional query in django [closed]
Am worried that it may cause any problem, as am using conditional querying paramters. Here is my query: data = Project.objects.filter(user=user if user.role == 1 else user.staff_to_id) In this, staff_to_idis just a self reference to a user to represents that this is a staff. So if Role == 1 then Projects will be fetched using "user" and when Role == 2 or something else it will Project will be fetched using "user.staff_to_id" Is this a bad practice ? -
