Nope, no need to import anything manually. You've been bitten by a
"quirk" of Python. Notice that you have this:
prepopulate_from=("title")
That's *almost* right. In the documentation, they show a two element
tuple, ("pre_name", "name"). You only have a one element tuple.
However, you did it wrong. A one element tuple in Python *has* to have
a trailing comma, so it should be
prepopulate_from=("title",)
Alternatively, you can use a list instead of a tuple, then you don't
need the comma
prepopulate_from=["title"]
The trailing comma in a tuple is required so Python knows whether or
not you are creating a tuple, or just simply putting brackets around
an expression.
Hope that helps,
Jay P.
