Would there be a way to do something like this:
If contrib.contenttypes are in settings.INSTALLED_APPS:
Add to models.Model a method:
get_content_type that returns the ContentType object?.
That way, any model I have will have that method available to easily and
quickly get its content type.
I've been playing with apps that relate to content types more and this
seems like a useful thing to have.
I tried adding a method to my model along the lines of this:
def get_content_type(self):
cm = ContentTypeManager()
return cm.get_for_model(self)
But that failed:
>>> from innovate.innovation.models import Innovation
>>> i = Innovation.objects.get(id=1)
>>> i.get_content_type()
Traceback (most recent call last):
File "<console>", line 1, in ?
File
"/Users/rhudson/sandbox/innovate/../innovate/innovation/models.py", line
37, in get_content_type
return cm.get_for_model(self)
File
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/django/contrib/contenttypes/models.py",
line 13, in get_for_model
ct, created =
self.model._default_manager.get_or_create(app_label=opts.app_label,
AttributeError: 'NoneType' object has no attribute '_default_manager'
So I ended up hard coding it, which is ok, I suppose:
def get_content_type(self):
return ContentType.objects.get(app_label__exact="innovation",
model__exact="innovation")
It just seems like a more introspective way to do this could come in handy.
