created_at filter does not work - causes error "Does not refer to a field"

You say that created_at is bulit into Django but any time I add it to my array of list_filter it spits out an error The value of 'list_filter[1]' refers to 'created_at', which does not refer to a Field. Has this changed? I don't see it in the documentation link provided.

I believe that it's not built in. Rather, it's referring to an attribute of a model. Check models.py and the Course attributes. You should see 'created_at' there.

While following along at home I noticed that the is_live filter didn't work, as it was sneakily added to the workspaces Course model without mention. I had to manually add it, set the default to false, then adjust for experimenting.
