unexpected keyword argument 'timeout' on Celery/Redis run on Django
I'm trying to set a environment on AWS (identical to another env I have that runs Celery perfectly) but I'm having this issue when I run celery -A core worker --loglevel=INFO [2022-08-03 12:59:06,633: CRITICAL/MainProcess] Unrecoverable error: TypeError("wrapped_func() got an unexpected keyword argument 'timeout'") I've already tried to upgrade and downgrade celery/redis/kumbu versions and nothing works. I oppened a python shell on this EC2 and tested the Redis connection and its working redis_client = redis.Redis(host=settings.REDIS_URL, port=6379) redis_client.set('key', 'value', nx=True, ex=5) I don't know what am I missing here.. My versions are celery==5.2.7 Django==3.1 django-celery-beat==2.3.0 kombu==5.2.4 redis==4.3.4 pip==22.1.2 setuptools==58.0.0 -
django - track data in formset which haven't been changed
I've created UpdateView with formset. The point is one of field in each formset should be filled after post. this field is calculated in function based on values from main form and some from formset but only when user clicks specific button in template. The user doesn't have to change anything in formset. It's not allowed. I've got code as folows: class DocUpdateView(UpdateView): model = Doc form_class = NewDocForm template_name = 'addatts.html' def get_success_url(self): return reverse('doc_detail', kwargs={'pk': self.object.doc_pk}) def get_context_data(self, **kwargs): context = super(DocUpdateView, self).get_context_data(**kwargs) if self.request.POST: context['form'] = NewDocForm(self.request.POST, instance=self.object) context['formset'] = MyModelFormSet(self.request.POST, instance=self.object) else: context['form'] = NewDocForm(instance=self.object) context['formset'] = MyModelFormSet(instance=self.object) return context def post(self, request, *args, **kwargs): self.object = self.get_object() form_class = self.get_form_class() form = self.get_form(form_class) formset = MyModelFormSet(self.request.POST, instance=self.object) print(f'formset valid: {formset.is_valid()}') if form.is_valid() and formset.is_valid(): return self.form_valid(form, formset) else: return self.form_invalid(form, formset) def form_valid(self, form, formset): self.object = form.save(commit=False) self.object.save() instances = formset.save(commit=False) print(instances) if 'sub_butt_1' in self.request.POST: for instance in instances: # here I wanted do logic with calculations instance.save() return HttpResponseRedirect(self.get_success_url()) def form_invalid(self, form, formset): return self.render_to_response(self.get_context_data(form=form,formset=formset)) Howewer every time I print 'intances' there is only emply list. What am Idoing wrong? -
Redis SADD multiple workers
I am using Redis server version 7.0.0 with Django-Redis. I have multiple workers in production and plan to use Django Redis's get_redis_connection.sadd to add values to a Set() in Redis. When multiple workers do that in Production, will data be lost due to two workers executing simultaneously? I read that Redis's I/O is single-threaded before version 6.0; since I am using 7.0 (I/O multi-threaded), can concurrency issues/race conditions exist? -
Access Django ModelChoiceField form field value inside __init__
I would like to make the certain field in my formset read-only once the value has been chosen. Kind of like this: class MyModelForm(forms.ModelForm): class Meta: model = MyModel fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.fields["my_field"].value is not None: self.fields["my_field"].disabled == True Except ModelChoiceField object doesn't have an arguement value and I am not even sure __init__ it is the right place to try access value of a formmset form's field. -

how to convert and save String to float field without rounding it in Django
I have a value of the string that is like 30.72044543304425 and am saving it to a FloatField as a float. example my_string = "30.72044543304425" object = something.objects.get(id=123) object.myFloatField = float(my_string ) object.save() but the result is 30.7204454330443 As you see the number has been rounded ..how to avoid this? -
Azure Batch OutputFiles upload from all compute nodes
I have a mpi-based task, where each thread writes files on 'working-directory' for each compute node on Azure-Batch. The task is configured to upload result (files) to my storage account. But only the files on the master node are uploaded to storage. I want to know, how can I make all the nodes to upload files to my storage account ? Is there any intermediate way to copy the files on to the files from the slave nodes to the master node and upload to storage account ? -
Can I use the current logged in user in models.py?
What I have: The default django User model with an attached Profile model that, amongst others, contains a ForeignKey to an Office model. So every user in my application is tied to a specific office. And in each office there are several Shifts. models.py: class Profile(models.Model): id = models.AutoField(primary_key=True) user = models.OneToOneField(User, on_delete=models.CASCADE) office = models.ForeignKey(Office, on_delete=models.RESTRICT) class Office(models.Model): id = models.AutoField(primary_key=True) short_name = models.CharField(max_length=3, default='FRA', null=True, unique=True) long_name = models.CharField(max_length=10, default='Frankfurt', null=True, unique=True) class Shift(models.Model): id = models.AutoField(primary_key=True) office = models.ForeignKey(Office, on_delete=models.RESTRICT) short_name = models.CharField(max_length=5, default="") long_name = models.CharField(max_length=20, default="") What I am trying to do: Now, in my CreateView I want to limit the available choices in the "shift" field to the ones attached to the office of the current logged in user. I thought about using the limit_choices_to option of ForeignKey, but I can't get my head around how to access the user information within a model? Something like class Shift(models.Model): id = models.AutoField(primary_key=True) office = models.ForeignKey(Office, on_delete=models.RESTRICT, limit_choices_to={'office': ???}) short_name = models.CharField(max_length=5, default="") long_name = models.CharField(max_length=20, default="") -
Error with Next.js getStaticPaths or getStaticProps in docker build process

Recommend way and maximum byte size for requests in a data-intensive Django application
I am working on an application that handles datasets with varyiing sizes. For POST requests I do a check on the attached .csv-File for byte size like and if its over 10mb, I return a BAD_REQUEST response: MAX_FILESIZE_BYTES = 10485760 # 10mb csvFile = request.data["file"] if(csvFile.size > MAX_FILESIZE_BYTES): raise Exception("File size over "+str(MAX_FILESIZE_BYTES)) except Exception as e: return Response("Uploaded File bigger than maximum filesize", status=BAD_REQUEST, exception=True) Is this the recommend way of handling files too big? And is 10mb a reasonable size, or could my application handle much bigger sizes?

Django variable doesn't get passed to template
Basically, what happens here, the list user_data doesn't get passed to the template, I can't figure out why. Does anyone have any ideas please? When I use the search bar I just get the else condition from the template, and it never shows any variable.

How to get a proper and query with django where not exists statement
So I have this query which I would like to use as a filter: select * from api_document ad where not exists ( select 1 from api_documentactionuser ad2 where ad2.user_id=4 and ad2.action_id=3 and ad.id = ad2.document_id limit 1 ) What I've tried with django is: q = queryset.exclude( Q(documentactionuser__action__id=3) & Q(documentactionuser__user=current_user), ) while queryset is a queryset on the api_document table. When I print the generated query however, django keeps separating the two conditions into two queries instead of simply using and, which in turn gives me the wrong data back: select * FROM "api_document" WHERE NOT ( EXISTS(SELECT 1 AS "a" FROM "api_documentactionuser" U1 WHERE (U1."action_id" = 3 AND U1."document_id" = ("api_document"."id")) LIMIT 1) AND EXISTS(SELECT 1 AS "a" FROM "api_documentactionuser" U1 WHERE (U1."user_id" = 1 AND U1."document_id" = ("api_document"."id")) LIMIT 1) ) I've tried chaining exclude().exclude(), filter(~@()).filter(~@()) and the above variant and it all returns nearly the same query, with the same data output -
How to fix out of sync Django migration with unique constraint
I had a model that looked something like this: class FooBar(models.Model): foo = models.ForeignKey(Foo, on_delete=models.CASCADE) bar = models.ForeignKey(Bar, on_delete=models.CASCADE) <some other fields> class Meta: constraints = [ models.UniqueConstraint(fields=['foo', 'bar'], name='foobar_candidate_key') ] I deleted the fields foo and bar and made the migrations and ran the migrations. I had not deleted the Meta class when I did this. I noticed that I forgot to remove the Meta class and removed it. Then I made the migrations again and tried to migrate. I got an error like: django.db.utils.OperationalError: (1091, "Can't DROP 'foobar_candidate_key'; check that column/key exists") How can I fix? I have considered using --fake but I'm worried that the constraint is still in the database constraints and I need it removed? -

mock assert_called_with treat argument as unordered list
I have some mocked function and I try to test that the arguments I pass there are correct. One of the arguments is a list generated based on DB queryset, lets say [{"id": 1}, {"id": 13}] The function doesn't care about the order of dicts in a list, so it works the same with a reversed (shuffled) list. I also have a test to check arguments are passed correctly: function_mock.assert_called_once_with( argument1='some_string', argument2='another_string', argument3={'some_dict_key': False}, ... my_list=[{"id": 1}, {"id": 13}], ) The problem is that on different environments queryset produces records in different order, resulting in [{"id": 1}, {"id": 13}] on some environments and [{"id": 13}, {"id": 1}](different order) on other. This results in tests pass on some environments and fail on other. Is there a way to inform mock that this argument should be treated as an unordered list? Something similar to my_list=mock.any_order([{...}, {...}]) P.S. I know about call_args_list so I can check arguments one by one, and apply set when necessary, but I'd like to avoid this solution unless there is better one. -
