How to redirect from one view to another view in django?

Problems with running Python in Virtual environments after Python update
I used Python 3.7 for many Django projects using virtual environments (venv) under Windows. The Python path was C:\Program Files\Python37\python.exe now I upgrated python to 3.9 and the current path is C:\Program Files\Python39\python.exe Now when I want to run Python in any of my past projects, for example python manage.py runserver I get the error No Python at 'C:\Program Files\Python37\python.exe' Which is quite normal. How could I update each project in order to accept the new path? Is there a way to do this or should I better downgrade to Python 3.7 and use it forever? Renaming the folder where Python is installed doesn't seem a good idea. It must surely be a configuration file to change, a variable to set or whatever. I'm relatively new with Python and I never faced this problem before. Could you help? -
Too many SQL queries with Django Admin many-to-many inline view
I have a 'diamond' relationship between four models. AlignedScan is basically a pay-load carrying model facilitating a many-to-many relationship between Scan and Alignment. Both Scan and Alignment have a to-one relationship to Scan Project. When trying to display a inline-list of AlignedScans in an Alignment detail window (in Django Admin), it works but is very slow due to two extra SQL queries being executed for each record. What am I doing wrong? These are my models: from django.contrib.gis.db import models from django.db.models import Count, Q class ScanProject_Manager(models.Manager): def get_queryset(self): return (super().get_queryset() .annotate(number_of_alignments=Count('alignments', distinct=True)) .annotate(number_of_usedscans=Count('scans', distinct=True, filter=Q(scans__used=True))) ) class ScanProject(models.Model): objects = ScanProject_Manager() slug = models.CharField(max_length=30,primary_key=True,) label = models.CharField(max_length=100,) #... class Scan(models.Model): name = models.CharField(max_length=24,) #... scanproject = models.ForeignKey( ScanProject, related_name='scans', on_delete=models.CASCADE, ) class Alignment(models.Model): aligned_when = models.CharField(max_length=13,) #... scanproject = models.ForeignKey( ScanProject, related_name='alignments', on_delete=models.CASCADE, ) class AlignedScan(models.Model): registered = models.BooleanField() x = models.FloatField(blank=True, null=True,) y = models.FloatField(blank=True, null=True,) z = models.FloatField(blank=True, null=True,) #... alignment = models.ForeignKey( Alignment, related_name='alignedscans', on_delete=models.CASCADE, \ ) scan = models.ForeignKey( Scan, related_name='alignedscans', on_delete=models.CASCADE, ) class AlignedScan_Manager(models.Manager): def get_queryset(self): return super().get_queryset().select_related('scan') I've tried with and without the AlignedScan_Manager, I've tried using a plain-vanilla straight out of the box InlineModel: class AlignedScan_Inline(admin.TabularInline): model = AlignedScan and i've tried … -

Factory_boy not creating RelatedFactory in Trait
I've got a Purchase model and a PurchaseInfo model. PurchaseInfo has a foreign key to Purchase. I'm trying to modify an existing Factory for Purchase that will create PurchaseInfo at the same time using RelatedFactory since it's a reverse foreign key relationship. The only thing is that I wanted to use a Taint so that I could control the value of fields within PurchaseInfo. Normally when I create a Purchase like p = PurchaseFactory() the PurchaseInfo is created with null fields inside of it. If I create a Purchase like p = PurchaseFactory(info=True), so I can get the field modifications via the Taint, the PurchaseInfo is not created at all. I have a feeling that putting the RelatedFactory in a Taint is not the way to go. What is the correct way to do this? Models: class Purchase(Model): ... class PurchaseInfo(Model): purchase = models.ForeignKey(Purchase, on_delete=models.CASCADE, unique=True, db_index=True) lock = DateTimeField(null=True) lock_by = ForeignKey(... class PurchaseInfoFactory(DjangoModelFactory): class Meta: model = PurchaseOrderInternalField lock = None lock_by = None class PurchaseFactory(DjangoModelFactory): class Meta: model = Purchase info = RelatedFactory(PurchaseInfoFactory, factory_related_name='purchase') class Params: info = Trait(internalfield=RelatedFactory(PurchaseInfoFactory, factory_related_name='purchase', lock=timezone.now() - relativedelta(months=1), lock_by=SubFactory(UserFactory, user_id=1))) -

Django tests pass individually but fail when running together
I have a number of tests that all pass if I just run the file individually in Pycharm. But if run them as using the DiscoverRunner some of them fail. I know it must have something to do with the tests setup, so I am looking for input on how to debug this. Things I already tried based on other stackoverflow answers: Make sure all the testscases are django.test.TestCase. Most test load data from fixtures in the class definition. Make sure to call the super method where I define the tearDown method. I had two tests files that used mail.outbox when run together. But if I put them together in a package inside the test folder they suddenly passed. Any idea what could be causing this? Any tips on how to debug this?
