Thank you for the suggestion.
I actually ended up extending Django's json serializer. Here is the
code in case you or someone else needs to do something like this.
from django.core.serializers.json import Serializer as JsonSerializer
from django.utils.encoding import is_protected_type
class DisplayNameJsonSerializer(JsonSerializer):
def handle_field(self, obj, field):
value = field._get_val_from_obj(obj)
#If the object has a get_field_display() method, use it.
display_method = "get_%s_display" % field.name
if hasattr(obj, display_method):
self._current[field.name] = getattr(obj, display_method)()
# Protected types (i.e., primitives like None, numbers, dates,
# and Decimals) are passed through as is. All other values are
# converted to string first.
elif is_protected_type(value):
self._current[field.name] = value
else:
self._current[field.name] = field.value_to_string(obj)
