Django change external user-facing field name

I have a model that will have two similar "id"-like fields. One will be the primary key, one will be the a human-readable id.

On the backed/in the model, I have differentiated them as such

pk_id = models.AutoField(primary_key=True) # internal only, incrementing int
ext_id = models.CharField(max_length=128) # external facing, words+int

When the user does a query to get a list of the models, I want to EXCLUDE pk_id entirely, and have ext_id appear simply under the name id. Like this:

{
'id' : 'name_title_001' # same as ext_id
'other_fields' : 'bla bla bla'
}

How do I accomplish this?

suppose your model name is SomeModel; Update your serializers as

class SomeModelSerializer(serializers.ModelSerializer):
    id = serializers.CharField(source='ext_id', read_only=True)
    class Meta:
        model = SomeModel
        fields = (
            'id',
            # other fields excluding pk_id and ext_id
        )
