Error in docs / auth / Programmatically creating permissions

[German Larrain]

In the example included in ​https://docs.djangoproject.com/en/dev/topics/auth/default/#programmatically-creating-permissions (versions 1.4, 1.5, and dev) there is a mistake in the sentence

content_type = ContentType.objects.get(app_label='myapp', model='BlogPost')

since that will raise

DoesNotExist: ContentType matching query does not exist.

since model argument must be in lower case. Thus the correct sentence would be

content_type = ContentType.objects.get(app_label='myapp', model='blogpost')

Perhaps an overall improvement would be to use method get_for_model of ContentTypeManager instead of get because it

"Returns the ContentType object for a given model, creating the ContentType if necessary. Lookups are cached so that subsequent lookups for the same model don't hit the database."

In that case, the proposed solution is to replace the abovementioned sentence with:

from myapp.models import BlogPost
content_type = ContentType.objects.get_for_model(BlogPost)
