Allow using class properties of models for populating fields in serializers

[pktiuk]

One of the features I miss in DRF is mapping serializer fields to properties of selected models. (It could be a good alternative to some ReadWriteSerializerMethodFields )

Desired usage example:

models.py

# We have a model which stores some data in a different format than we are going to serve it class Location(models.Model): lattitude_degrees = models.FloatField() @property def lat_radians(self): return deg_to_rad(self.lattitude_degrees) @lat_radians.setter def lat_radians(self, lat: float): self.lattitude_degrees = rad_to_deg(lat)

serializers.py

class LocationSerializer(serializers.ModelSerializer): class Meta: model = models.Location fields = ["lat_radians"] lat_radians = serializers.FloatField(source="lat_radians")

I think it's because ModelSerializer cannot infer the field type without a model field.

Have you tried the following?

class LocationSerializer(serializers.ModelSerializer): lat_radians = serializers.FloatField() class Meta: model = models.Location fields = ["lat_radians"]

I think it's because ModelSerializer cannot infer the field type without a model field.

I updated my example to address this issue.

Have you tried the following?

I will check this out and let you know

It works as you said. Thank you for quick answer
