True, but right now I have the initial_data written as:
INSERT INTO ... VALUES ((select id from django_content_type where name =
'profile'), ......);
Which stays OK, even if I add/remove Models (which change the
content_type table content!)

What about letting users use python scripts to generate the initial data
(if really needed/wanted)?
---<initial_data.py>--------------------------------------
json = """
[
{
content_type: {{profile_contenttype.id}}
}
// more regular json goes here
]
"""
from django.template import Context, Template
from django.contrib.contenttypes.models import ContentType
def get_json():
c = Context({'profile_content_type': ContentType.objects.get.....})
t = Template(json )
return t.render(c)
---</initial_data.py>--------------------------------------
I know that this kind of goes against what fixtures should be, but it
would be pretty flexible...
