Re: Disadvantages of using model name rather than model class for FK field?

Class might be easier to use for beginner and is explicit. There is an
import, you know what you are dealing with and you get clear error
when you do things wrong.

If you have circular depencencies, using model name can be the only solution.
If you have model A with a foreign key on model B and model B with a
foreign key on model A, both in the same file, using class is a no go.
You will try to reference a model that is not yet declared, causing
error.
That's the primary use case for model name.
