我創建YAML夾具夾具處理但未加載（繼承的模型）
test.yaml：
- model: myapp.person
pk: 1
fields:
email: [email protected]
params: []
tests.py：
class MyTests(TestCase):
fixtures = ['test.yaml']
def test_1(self):
# import pdb; pdb.set_trace()
person = Person.objects.get(pk=1)
測試結果是
Traceback (most recent call last):
File "/home/django/myapp/tests.py", line 99, in test_part_count
person = Person.objects.get(pk=1)
File "/usr/lib/python3/dist-packages/django/db/models/manager.py", line 85, in manager_method
return getattr(self.get_queryset(), name)(*args, **kwargs)
File "/usr/lib/python3/dist-packages/django/db/models/query.py", line 385, in get self.model._meta.object_name
myapp.models.DoesNotExist: Person matching query does not exist.
如果我取消註釋pdb.set_跟蹤（），並檢查了Person.objects.all()
(Pdb) Person
<class 'myapp.models.Person'>
(Pdb) Person.objects.all()
<QuerySet []>
所以我認爲，燈具不填充數據庫。
所以我檢查夾具文件是否被讀取。我改變參數paramz並得到
Traceback (most recent call last):

所以這是證明，測試讀取文件，並與數據庫檢查。那麼爲什麼人是空的？
UPDATE
def setUp(self):
call_command('loaddata', 'test.yaml', verbosity=2)
我說這tests.py中，得到了更多的詳細程度：
Loading 'test' fixtures...
Checking '/home/django/myapp/fixtures' for fixtures...
Checking '/home/django/fixtures' for fixtures...
No fixture 'test' in '/home/django/fixtures'.
Checking '/home/django' for fixtures...
No fixture 'test' in '/home/django'.
Installing yaml fixture 'test' from '/home/django/myapp/fixtures'.
Installed 1 object(s) from 1 fixture(s)
但：
(Pdb) Person
<class 'myapp.models.Person'>
(Pdb) Person.objects.all()
<QuerySet []>
這是怎麼回事....
