“string indices must be integers” when trying to load test yaml data

Question

I'm trying to figure out how to load test data in Django and Python 3.7. I have the below YAML file

website:
 - id: 1
   path: "/test"

Pretty basic. In my unit test, I attempt to load it using

management.call_command('loaddata', 'test_data.yaml', verbosity=0)

But this results in the below error. What's wrong with my YAML file that would cause the below error?

======================================================================
ERROR: test_add_articlestat (mainpage.tests.FirstTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/davea/Documents/workspace/mainpage_project/venv/lib/python3.7/site-packages/django/core/serializers/pyyaml.py", line 73, in Deserializer
    yield from PythonDeserializer(yaml.load(stream, Loader=SafeLoader), **options)
  File "/Users/davea/Documents/workspace/mainpage_project/venv/lib/python3.7/site-packages/django/core/serializers/python.py", line 91, in Deserializer
    Model = _get_model(d["model"])
TypeError: string indices must be integers

Answer 1

The first line does not look right to me:

website:

The correct format is

-model: appname:modelname
