You have not defined __str__ on B, so this isn't entirely unexpected
(although I am not completely sure what you're seeing, but anything is
not unexpected here).
Note that the estudi_oferit field is many-to-many, so it has no
"natural" way to be represented as a string. After all, it could be
referring to 10,000 objects at the other end. There's no way to display
that naturally.
Explicitly define a __str__ method on B that displays the fields you
want. Django's default __str__ is rarely the right thing to use.
