Creates a model serializer class on the fly, just taking the model (class) as its argument.

My use case: When importing data from spreadsheets, the DRF serializers are an easy way to create model instances from a dictionary. This function saves me from creating a custom serializer each time I add a new importer.

Using __all__ is dangerous ;-)

Here’s a little snippet for creating serializers on the fly:

```
from rest_framework.serializers import ModelSerializer

def serializer_factory(model):
    cls_name = f"{model.__name__}Serializer"
    return type(
        cls_name,
        (ModelSerializer,),
        {"Meta": type("Meta", (), {"model": model, "fields": "__all__"})},
    )
```
