Django: Data corrupted after loading? (possible programmer error)
- by Rosarch
I may be loading data the wrong way.
excerpt of data.json:
{
"pk": "1",
"model": "myapp.Course",
"fields":
{
"name": "Introduction to Web Design",
"requiredFor": [9],
"offeringSchool": 1,
"pre_reqs": [],
"offeredIn": [1, 5, 9]
}
},
I run python manage.py loaddata -v2 data:
Installed 36 object(s) from 1
fixture(s)
Then, I go to check the above object using the Django shell:
>>> info = Course.objects.filter(id=1)
>>> info.get().pre_reqs.all()
[<Course: Intermediate Web Programming>] # WRONG! There should be no pre-reqs
>>> from django.core import serializers
>>> serializers.serialize("json", info)
'[{"pk": 1, "model": "Apollo.course", "fields": {"pre_reqs": [11], "offeredIn": [1, 5, 9], "offeringSchool": 1, "name": "Introduction to Web Design", "requiredFor": [9]}}]'
The serialized output of the model is not the same as the input that was given to loaddata. The output has a non-empty pre_req list, whereas the input's pre_reqs field is empty. What am I doing wrong?
