Hi Mike,
Not a serious blunder, but I think there may be a small mistake in part
2, where you describe updating an email address:
# change the first address
prof.addresses[0] = Address("[email protected]")
I don't think this is going to update the '[email protected]' row in the
database to say '[email protected]'. Instead, it is going to disconnect
that row from the user by setting the user_id to NULL, and add a new row
with the new address. (This may be what you intended, but I don't think
it's clear from the description).
I would have thought that you'd actually want to write this:
# change the first address
prof.addresses[0].email_address = "[email protected]"
Hope that helps,
Simon
