Django dump data for a single model?

Question

Can I perform a dumpdata in Django on just a single model, rather than the whole app, and if so, how?

For an app it would be:

python man         


        

Answer 1

As noted, you can't do this through a manage.py command in Django 1.0. However you could use a script to export the JSON file, and load it using loaddata:

from django.core import serializers
from myproject.myapp import models
data = serializers.serialize("json", models.MyModel.objects.all())
out = open("mymodel.json", "w")
out.write(data)
out.close()

Answer 2

I've created a management command the generate a fixture on a per model basis. Fixtures can be generated by running:

./manage generate_fixtures app.model.MyModel --file=dump/MyModel.json

Answer 3

Take all data into json format from django model.

Syntax:

python manage.py dumpdata app_name.model_name

For example dumping data from group_permission model which reside in default auth app in django.

python manage.py dumpdata auth.group_permission

For output take a look on console.
