Django customUser models
I have faced two or three issues with django customuser model. The first one being the skills models. I wanted to add the Skills in the custom user, realized that there has been some drawbacks, things like, I can not add this skill field properly and when adding the age in django, I dont kno, but the age field seems a bit confusing.

django project does not write to file and there is no error, the file does not appear
I'm trying to write to a file and django doesn't do it. There is no error of any kind but the file does not appear. Using the process monitor I don't see any attempt to write. In a python file the same code works fine. Test performed: @method_decorator(login_required, name='dispatch') class TestWrite(TemplateView): template_name = 'test.html' with open(r'd:\djangotest.txt', "w") as fo: fo.write('test') fo.close() I did the test with Popen and it doesn't work either. p = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True) stdout, stderr = p.communicate() returncode = p.returncode In the case of Popen I used pg_dump.exe and in stderr I got the result of the program running correctly but no file anywhere. It doesn't matter which path you select to write, inside the project, outside of it, ect. the file does not appear. I don't know if it's important, but I did the tests in pycharm. -

Django models: is it possible to force icontains on filter/get for specific field using a manager?
Let's say I have a model with a string field similar to this class Product(models.Model): upc = models.CharField(max_length=12, blank=False, null=False) Is it possible to build a model manager or something similar where every time I use Product.objects.get/Product.objects.filter it overrides the default lookup to force the search/filter to behave like I had used icontains? As in: Product.objects.get(upc="012345678902") Product.objects.filter(upc="012345678902") By default would behave like: Product.objects.get(upc__icontains="012345678902") Product.objects.filter(upc__icontains="012345678902") -

Getting objects before validating data Django REST
I have to create a new Chat object using this view: class ChatListCreateView(ListCreateAPIView): permission_classes = [IsAuthenticated] serializer_class = ChatSerializer def get_queryset(self): data = Chat.objects.filter( Q(employees=self.request.user) | Q(created_by=self.request.user)).distinct() return data The serializer it uses is: class ChatSerializer(serializers.ModelSerializer): created_by = SimpleEmployeeSerializer(read_only=True) employees = SimpleEmployeeSerializer(many=True, read_only=True) title = serializers.CharField(max_length=255) def create(self, validated_data): """ Creates a new Chat and adds the m2m employees to it """ # Create and save the chat chat = Chat.objects.create( created_by=self.context['request'].user, title=validated_data['title'], ) # Add the employees to the chat validated_employees = validated_data.pop('employees') for user_id in validated_employees: employee = Employee.objects.get(id=user_id) chat.employees.add(employee) return chat My issue is that the SimpleEmployeeSerializer expects a user object but I am submitting an array of employees as such: { "title": "fwef", "employees": [ { "id": "8" }, { "id": "30" } ] } What method can I implement to get the objects from these IDs before validation? -
