Django combining the names of my two apps, and saying no module named that, with a module not found error
I'm new to django and doing my first project, I have just made a second app for my project, and I had thought that I set everything up properly.

I tried to add "homepagecourses" into my installed apps in settings but then it just said it couldn't find "homepagecourseshomepagecourses". My file directory looks like this -

Adding custom expensive field on Django model serializer
Normally, in Django, using rest_framework, to add a custom field to a model, you can use SerializerMethodField. From what I understand however, this works great for values that are easy to calculate, but if the value requires database queries to related tables, you're going to be performing these for every item being returned. If I have a ViewSet like this: class ProductViewSet(ModelViewSet): queryset = models.Product.objects.all() serializer_class = serializers.ProductSerializer ... And a Serializer like this: class ProductSerializer(ModelSerializer): class Meta: model = models.Product fields = "__all__" How do I run a bulk query to get some data from a related table for all the products being serialized, and attach it to a new field. Ex: if each product is attached to an Order, maybe I want to add an order_number field. I could do this: class ProductSerializer(ModelSerializer): order_number = SerializerMethodField() @staticmethod def get_order_number(obj): return obj.order.order_number class Meta: model = models.Product fields = "__all__" But if the view is returning 100 products, that will be 100 database queries. Is there a more efficient way to do this? -

Each time I create superuser, Django saves the user but throws an error that user already exists even if it has never existed
I am fairly new to advanced Django and using Django 4.2 and PostGreSql 9.5 with PgAdmin4. I am trying to create a website, where users can sign in with email and password.

Reference Django Model Field from iterator in a for loop
I am attempting to create a model record using a for loop and cannot figure out how to reference the model field in a django create() function. I have mirrored response keys to the model fieldnames and want to loop through the response keys and assign the values in the model. Here is a simplified example. r = requests.get(url) r = r.json() ModelOne.objects.create( for field in r: ModelOne.field = r[field] ) I am trying to create the equivalent of ModelOne.Objects.create( fieldone = r[fieldone] ,fieldtwo = r[fieldtwo] ) Model: class ModelOne(models.Model): fieldone = models.IntegerField(blank=True, null=True) fieldtwo = models.IntegerField(blank=True, null=True) What I do not think works is trying to use .field in ModelOne.field as the object attribute. It doesn't return any errors but does not save the record either. I have also tried using raw sql with the django connection library but run into many other hurdles with that method. Is there a way to do this using the QuerySet API or should I be looking into another way? -
