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.

DRF updating data using AJAX call
When I try to send data via the frontend to the serializer I get a HTTP 400 error. If I do it directly via the DRF browsable API it works though: model: class Shipment(models.Model): name = models.CharField("name", max_length = 128) date = models.DateField() class Product(models.Model): serial = models.CharField("serial", max_length = 31, unique = True) shipment = models.ForeignKey(Shipment, on_delete = models.CASCADE, blank = True, null = True) serializer: class ShipmentSerializer(serializers.ModelSerializer): class Meta: model = Shipment fields = ["id", "name",] class ProductSerializer(serializers.ModelSerializer): shipment = ShipmentSerializer() def update(self, instance, request): product = Product.objects.get(serial = instance) product.shipment = Shipment.objects.get(id = request["shipment"]["id"]) product.save() return instance class Meta: model = Product fields = ["serial", "shipment",] lookup_field = "serial" read_only_fields = ["serial",] ViewSet: class ProductViewSet(ModelViewSet): serializer_class = ProductSerializer lookup_field = "serial" http_method_names = ["get", "patch", "put"] def get_queryset(self): return Product.objects.all() AJAX call: $.ajax({url: `api/products/${serial}/`, dataType: "json", contentType: "application/json", type: "PUT", data: {"shipment": shipment[0]}, headers: {"X-CSRFTOKEN": csrf_token }, success: function () {window.location = "?msg=ok";}, error: function () {window.location = "?msg=error";} }); Browser output: PUT http://127.0.0.1:8000/api/products/d39f281f/ Status400 Bad Request VersionHTTP/1.1 Transferred400 B (111 B size) Referrer Policysame-origin Request payload: shipment=4 Response: {"shipment":["This field is required."]} or after some playing: JSON parse error - Expecting value: line 1 column 1 … -
Filter Django-Function-View Queryset for User.Request
Models.py class Experience(models.Model): user = models.ForeignKey(User, null=True, on_delete = models.CASCADE) company_name = models.CharField(max_length=100) company_address = models.CharField(max_length=200) post_held = models.CharField(max_length=30) year_from = models.CharField(max_length=20) year_to = models.CharField(max_length=20) info = models.TextField() def get_absolute_url(self): return reverse('resume') def __str__ (self): return self.company_name Views.py def Resume(request): experience = Experience.objects.filter(user = request.user) return render(request, 'resume.html', {'experience': experience}) Template <ul> {% for an_experience in experience %} <a href="{% url 'edit_experience' an_experience.pk %}"><li ><h5>{{ an_experience }},</h5></a> {{ an_experience.company_address }} - {{ an_experience.post_held }}</li> <small>{{ an_experience.year_from }} - {{ an_experience.year_to }}</small> <div> {{ an_experience.info }} </div> {% endfor %} </ul> if I use .all(), it is working perfectly but while trying to filter it using request.user nothing is displaying in the template file.
