I guess you have quotes around the name of the class, so that the
Referenced
class is really a string that does not have '_meta' attribute.
I tried what suggested, i.e to import the class from where is is
defined but
I met another problem. I've got a 'Film' model Class and a proposed_by
field that should reference django User, so in models.py I did:
from django.contrib.auth.models import User
(...)
class Film(models.Model):
...
proposto_da = models.ForeignKey(User, blank=True)
When I try to edit with the admin interfaces django raises an error:
Exception Type: OperationalError
Exception Value: no such column: film_film.proposto_da_id
Why does it look for film_film.proposto_da_id. Of course this is not a
valid
name!
The sqlite schema seems correct:
CREATE TABLE "film_film" (
"id" integer NOT NULL PRIMARY KEY,
"titolo" varchar(100) NOT NULL,
"regista" varchar(40) NOT NULL,
"url_iann" varchar(200) NOT NULL,
"url_altri" varchar(200) ,
"anno" integer NOT NULL,
"image" varchar(100) NOT NULL,
"durata" integer NOT NULL,
"genere_id" integer NOT NULL REFERENCES "film_genere" ("id"),
"data_proiezione" date,
"proposto_da" integer REFERENCES "auth_user" ("id")
);
CREATE INDEX film_film_genere_id ON "film_film" ("genere_id");
Any help is appreciated!
Thanks
