Re: cannot get value(foreign key) after using distinct()
since you are using .first() in the query, it will return only 1 object so
I don't think using a for loop our 'category' in template will work

Custom User error
Greetings, I am starting in the world of django and I have some problems
with a custom user, for the registration of users to the database, the
example that I have works 100% with the user that comes by default allows
me to render the registration form user without any inconvenience, but when
I create a custom user the same screen for registration no longer works for
me, it no longer works for me, I have read a lot of the web but nothing
works for me. It should be something very simple, but I can't find what I
should do.
To make the change to a custom user, delete the database and the migration
that I had to create a clean database with the new model, but I have not
been able to do it.

Custom User error
Saludos, me estoy iniciando en el mundo de django y tengo algunos problemas
con un usuario personalizado, para el registro de usuarios a la base de
datos, el ejemplo que tengo funciona al 100% con el usuario que viene por
defecto me permite renderizar el formulario de registro de usuario sin
ningún inconveniente, pero cuando creo un usuario personalizado la misma
pantalla para el registro ya no funciona para mí, ya no funciona para mí,
he leído mucho de la web pero nada funciona para mí. Debería ser algo muy
simple, pero no puedo encontrar lo que debo hacer.
Para realizar el cambio a un usuario personalizado, borra la base de datos
y la migración que tuve para crear una base de datos limpia con el nuevo
modelo, pero no he podido hacerlo.
models.py
desde django.contrib.auth.models importar AbstractUser
clase UserProfile (AbstractBaseUser, PermissionsMixin):
# plantilla de tabla para usuarios de inicio de sesión del sistema con
correo electrónico
correo electrónico = modelos. EmailField (max_length = 255, unique = True,
verbose_name = 'E-mail')
nombre = modelos. CharField (max_length = 200)
is_active = modelos. BooleanField (predeterminado = Verdadero)
is_staff = modelos. BooleanField (predeterminado = False)
views.py
desde .forms importar UserProfile
def record (solicitud):
datos = {
'formulario': UserProfile ()
}
form = UserProfile (datos = solicitud. POST)
si form.is_valid ():
form.save ()
#authentic a la vez
usuario = autenticar (nombre de usuario = form.cleaned_data ["correo
electrónico"], contraseña = form.cleaned_data ["contraseña1"])
# Inicio sesión aquí
login (solicitud, usuario)
#redirect inicio
messages.success (solicitud, "Registrado correctamente")
redirigir de retorno (a = "inicio")
data ["form"] = formulario
devolución (solicitud, 'registro / registro.html', datos)
setting.py
AUTH_USER_MODEL = 'perfiles. UserProfile'
Repito con el modelo de usuario que viene por defecto de django, funciona
al 100%
Al ejecutar el servidor me arroja este error
TypeError at / record /
UserProfile () obtuvo un argumento de palabra clave inesperado 'data'

Apologies if this is stating the obvious, but to select more than one item,
are you using "shift+click" or "ctrl+click" or just "click"?
You need to use the modifier key with "click", not just "click".

cannot get value(foreign key) after using distinct()
Hi all,
There is a question when I use distinct().
When I try to use the ORM(distinct & value), I cannot get the value of the
attribute(foreign key).
models.py
class Category(models.Model):
category = models.CharField(max_length=20)
class Article(models.Model):
category = models.ForeignKey(Category, on_delete=models.CASCADE)
views.py
category =
Article.objects.filter(visible=True).values('category').distinct().first()
return_result.update({'category': category})
template/xxx.html
{% if category %}
{% for name in category %}
{{ name.category }}
...
the result is 4. (int) and there is no result if I type {{
name.category.category }}
I hope the result is Work which is the 4(category_id) refs.
Thanks,
Kath

How to get a chinese django tutorial
Dear Team, I recently learned django tutorials on django's website, which has tutorials in Chinese, but it's not convenient to visit django's website in my work environment. Is there any way to download the Chinese version of Django tutorial PDF file or epub file? -- You received this message because you are subscribed to the Google Groups "Django users" group.
