Fat`s formula on python
I have a formula: %fat=495/(1.29579-0.35004(log(hips+waist-neck))+0.22100(log(growth)))-450 How did this fat formula on python? I make it: from math import log fat = 495 / (1.29579 - 0.35004 * log(self.hips + self.waist - self.neck) + 0.22100 * log(self.user.profile.growth)) - 450 But the meanings are far from the truth.

If your program executing second.py file. How would you access variable with data of second.py file? [duplicate]
I've seen many post regarding this but doesn't found solution. You have first.py def AI_click(self): string="" os.system('python second.py') self.lineEdit.setText(string) If this method called, second.py will execute. In second.py you have, string="mntk" How will you use second.py string in first.py function? I also asked here This is nothing to do with import because in real second.py contain AI model and it predicts alphabets using ocr and store string value in variable. That's what I want to access in first.py -

Django - Unexpected behaviour with default ordering after annotations
I've discovered a rather odd case where if I set default ordering on a model to id or -id then add distinct annotations to the query, the default ordering is ignored and instead orders by id ascending regardless of what it is set as in the model Meta. However, when I choose a field that isn't specifically id as the default ordering of the model and do the same thing, the queryset is ordered correctly. It only seems to by id. What gives? I'm not sure if this is Django weirdness or postgres weirdness, is it because it's the primary key? If I use .order_by('-id') afterwards it orders as desired and if the ordering gets broken by annotating it, how come it doesn't always break? Example Django version: 4.1 Postgres version: 13.4 class OrderQuerySet(models.QuerySet): def annotateItemCounts(self): return self.annotate( num_items=Count('order_items', distinct=True), num_items_draft=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.DRAFT)), num_items_back_order=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.BACK_ORDER)), num_items_confirmed=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.CONFIRMED)), num_items_in_progress=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.IN_PROGRESS)), num_items_ready=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.READY)), num_items_packed=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.PACKED)), num_items_shipped=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.SHIPPED)), num_items_completed=Count('order_items', distinct=True, filter=Q(order_items__state=OrderItem.OrderItemState.COMPLETE)), ) class OrderManager(models.Manager): def get_queryset(self): return OrderQuerySet(self.model, using=self._db) def annotateItemCounts(self): return self.get_queryset().annotateItemCounts() class Order(models.Model): class Meta: ordering = ['-id'] ... -
Get top rows by one column Django
I'm making a job to categorize earnings and expenses, from app of movimentations. To this, i need get the category to tile, with more cases. For example, in this Scenario: | title | category | count | | ----- | -------------- | ----- | | Pizza | food | 6 | | Pizza | others_expense | 1 | | Pizza | refund | 1 | I want return just the first row, because the title is the same, and category food is used with most frequency.

Model: class Movimentation(models.Model): title = models.CharField(max_length=50) value = models.FloatField() category = models.CharField(max_length=50) Consult: My actual consult in Django ORM is.

Calculating serializers read only fields

Q: Where should i place this business logic? before serializer init, intercepting immutable request.data inside serializer validate() or validate_y() method. using get_y() of SerializerMethodField. inside create_mymodel() service. -

How to properly use multiprocessing module with Django?
I'm having a python 3.8+ program using Django and Postgresql which requires multiple threads or processes. I cannot use threads since the GLI will restrict them to a single process which results in an awful performance (especially since most of the threads are CPU bound). So the obvious solution was to use the multiprocessing module. But I've encountered several problems: When using spawn to generate new processes, I get the "Apps aren't loaded yet" error when the new process imports the Django models. This is because the new process doesn't have the database connection given to the main process by python manage.py runserver. I circumvented it by using fork instead of spawn (like advised here) so the connections are copied to the other processes but I feel like this is not the best solution and there should be a clean way to start new processes with the necessary connections. When several of the processes simultaneously access the database, sometimes false results are given back (partly even from wrong models / relations) which crashes the program. This can happen in the initial startup when fetching data but also when the program is running. I tried to use ISOLATION LEVEL SERIALIZABLE (like … -
