I've "fixed" the problem, but I don't understand exactly what was it.
The problem wasn't the import itself, but the moment in wich I was doing it.
Let's go back to the function that had the error, here with more detail
def instalar_nuevo_sitio(nombre):
sitio = db(db.sitios.nombre == nombre).select().first()
# here it does a lot of stuff
sitio.set_metodo_pago(metodopago='ticket') # this line throws the error
Notice the comment where I say that in that place, the function does "a lot
of stuff". What is that stuff? Well, what the function does is to install a
new app in web2py, that is, clonning the repository and putting all the
files needed by the new app.
How did I solve it? I just moved the sentence to the top, before doing that
"lot of stuff".
I don't know why exactly that worked, because the line that throwed the
error doesn't have anything to do with the new application installed by the
function.
Anyway, It's solved now, but I cannot say why :/
