Hi,
I'm using version 0.91.
To put it short, I get a TypeError when I try to use a foreign key.
Here's what I have:
_In Postgresql_
TABLE "cadastro_servicos" (
~ "id" serial NOT NULL PRIMARY KEY,
~ "codigo" text NOT NULL,
~ "nome" varchar(80) NOT NULL
);
TABLE "cadastro_cadastros" (
~ "id" serial NOT NULL PRIMARY KEY,
~ "serv_clientes_id" integer NOT NULL REFERENCES "cadastro_servicos"
("id"),
~ "nome" varchar(200) NOT NULL,
~ (...)
);
INSERT INTO "packages" ("label", "name") VALUES ('cadastro', 'cadastro');
INSERT INTO "content_types" ("name", "package", "python_module_name")
VALUES ('servico', 'cadastro', 'servicos');
INSERT INTO "content_types" ("name", "package", "python_module_name")
VALUES ('cadastro', 'cadastro', 'cadastros');
As _django models_:
class Servico(meta.Model):
~ codigo = meta.TextField(maxlength=4)
~ nome = meta.CharField(maxlength=80)
~ def __repr__(self):
~ return self.nome
class Cadastro(meta.Model):
~ serv_clientes = meta.ForeignKey(Servico)
~ nome = meta.CharField(maxlength=200)
~ (...)
~ def __repr__(self):
~ return self.nome
when I try:
lista_sps = cadastros.get_list(servicos__id__exact=2)
from within a view, I get:
TypeError at /cadastro/pesquisa/
got unexpected keyword argument 'servicos__id__exact'
The same happens from the interactive shell.
|>> cadastros.get_list(servico__nome__icontains='bel')
|>> cadastros.get_object(servico__nome__icontains='bel')
|>> cadastros.get_object(codigo__icontains='bel')
I've also tried, just in case:
|>> cadastros.get_object(Servico__nome__icontains='bel')
|>> cadastros.get_object(Servicos__nome__icontains='bel')
If I try to get a list or a object from either of the two classes alone
(with no references to the other) I have no problems getting the
information I want.
How did I build this? First I've developed the Cadastro model, and did
'python manage.py install cadastro'. At this time, cadastro had no
serv_clientes field.
Later on, I added the Servico class to the model, added the table to
Postgresql and changed the Cadastro model to include the serv_clientes
field.
Everything seems alright for me, but not for django. Why does 'got
unexpected keyword argument' happen? Can you give me some hints?
Luis
