Just as an aside, when I use this approach I find it handy to use a date field, 'deletedate' rather than a flag. This provides the extra bit about when an item was deleted, which can sometimes be useful later information on. > Rather than going to every function I am displaying items ( 99% of the > time I'm using .filter then some filter ), is there a way to tell it > in the model to always append delete_flag=0 to any of the .filter > parameters I am passing in, so that only non logically deleted items > are returned?

What you're probably looking for is a custom model manager that replaces the default manager for your models. Making a custom model manager is documented at http://www.djangoproject.com/documentation/models/custom_managers/ and the example case (published books) is very similar to what you're after. The only thing that example doesn't do is make the custom manager the default. This is accomplished simply by setting the model's 'objects' property to your custom manager. Bear in mind, however, that there can be side effects to applying a filter of this sort by default to all queries made through the manager. For example, since the admin application uses the default manager, items which are filtered out will be inaccessible from there. This issue is discussed in ticket #1855.
