DRF dynamic choices depend on current user

Question

is there any way to make choices dynamically depend on current user something like that:

class RideSerializer(serializers.ModelSerializer):
    provider_username = serializers.ChoiceField(choices=request.user.providers)

Answer 1

You can set the choices during in the constructor. The following code show the idea. You can pass the request via context https://www.django-rest-framework.org/api-guide/serializers/#including-extra-context

class RideSerializer(serializers.ModelSerializer):
    provider_username = serializers.ChoiceField()

    def __init__(self, *args, **kwargs):
       super().__init__(*args, **kwargs)
       self.fields["provider_username"].choices = request.user.providers
