Here's the custom manager code. I didn't have the latest version with
me, so I try to recreate the get_hot() method below.
class PublishedManager(models.Manager):
def get_query_set(self):
return super(PublishedManager,
self).get_query_set().filter(published=True).filter(category__published=True)
....
def get_hot(self):
return
self.get_query_set().filter(is_hot=True).latest('published_on')
Now, I'm not sure if this was the code that returns the DoesNotExist
exception, but the get_query_set() function definitely returns the
same exception if there are no news items flagged as published (or if
there are no news items in the DB at all).
Here's how I use the custom manager:
class Post(models.Model):
....
objects = models.Manager()
pub_objects = PublishedManager() # filters initial Qset to include
only
When I call the get_query_set() via Post.pub_objects.all(), the
DoesNotExist is returned if there are no matching posts, and this
shows up in the template, so I guess the same will happen if I do
Post.pub_objects.get_hot(). The former problem is not important
because there will always be news in the DB, but the latter is not
okay since there may not be hot items at least for some time after the
site is launched.
The extra_context part of the URLconf looks like this:
common_ec = {
'category_list': models.PostCategory.pub_objects.all(), #
DoesNotExist if no posts with published = True
'latest_post_list': models.Post.pub_objects.get_latest(),
'best_rated_post_list': models.Post.pub_objects.get_best_rated(),
'most_viewed_post_list': models.Post.pub_objects.get_most_viewed(),
'hottest_post_list': models.Post.pub_objects.get_hot(), #
DoesNotExist if not posts with is_hot = True
}
I have defined the common_ec dict separately so I can reuse it in
different generic view dictionaries.
