Desciption:
I have a generic function
def gen(model_name,model_type):
objects = model_name.objects.all()
for object in objects:
object.model_type = Null (Or some activity)
object.save()
How Can I achieve the above ? Is it possible?
I would use get_model:
from django.db.models import get_model
mymodel = get_model('some_app', 'SomeModel')
Cannot import name get_model in the first line. Did anything change in the latest Django version?
As of Django 1.7 the django.db.models.loading is deprecated (to be removed in 1.9) in favor of the the new application loading system. The 1.7 docs give us the following instead:
$ python manage.py shell
Python 2.7.6 (default, Mar 5 2014, 10:59:47)
>>> from django.apps import apps
>>> User = apps.get_model(app_label='auth', model_name='User')
>>> print User
<class 'django.contrib.auth.models.User'>
>>>
if you pass in 'app_label.model_name' you could use contenttypes e.g.
from django.contrib.contenttypes.models import ContentType
model_type = ContentType.objects.get(app_label=app_label, model=model_name)
objects = model_type.model_class().objects.all()
The full answer for Django 1.5 is:
from django.db.models.loading import AppCache
app_cache = AppCache()
model_class = app_cache.get_model(*'myapp.MyModel'.split('.',1))
