I use this script to export a group of models that I want to import later as initial data. It exports them as serialized json, which is perfect for importing later with the loaddata function in manage.py.

import sys, os

sys.path.append('/Path/To/Django/Projects/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

from django.core.serializers import serialize
from myproject.myapp import models

model_names = [] # a list of the names of the models you want to export

for model_name in model_names:
    cls = getattr(models, model_name)
    filename = model_name.lower() + ".json"
    file = open(filename, "w")
    file.write(serialize("json", cls.objects.all()))
