Django Fixtures: JSON Formatting

Posted on January 8, 2012

Came across an issue with Django Fixtures using the JSON format. Here was my fixture:

{
	"pk": 1,
	"model": "core.wine",
	"fields": {
		"name": "Juan Gil",
		"vintage": 2009
	}
}


            view raw
            initial_data_broken.json
            This Gist brought to you by GitHub.
          

Here's the error I was getting:

Problem installing fixture '.../core/fixtures/initial_data.json': Traceback (most recent call last):
  File ".../python2.6/site-packages/django/core/management/commands/loaddata.py", line 169, in handle
    for obj in objects:
  File "...python2.6/site-packages/django/core/serializers/json.py", line 35, in Deserializer
    for obj in PythonDeserializer(simplejson.load(stream), **options):
  File "...python2.6/site-packages/django/core/serializers/python.py", line 84, in Deserializer
    Model = _get_model(d["model"])
TypeError: string indices must be integers

The fix was simple, wrap the object in an array.

[
	{
		"pk": 1,
		"model": "core.wine",
		"fields": {
			"name": "Juan Gil",
			"vintage": 2009
		}
	}
]
