Hello colleagues,
I have the models.py:
class User(models.Model):
LastName = models.CharField(max_length=50, verbose_name =
"Фамилия")
FirstName = models.CharField(max_length=50, verbose_name = "Имя")
MidleName = models.CharField(max_length=50, verbose_name =
"Отчество")
class SoldServices(models.Model):
state_choices = (
('ACT', u'Активно'),
('PAS', u'Пасивно'),
('TRM', u'Отключено'),
)
Service = models.ForeignKey('Service', verbose_name = 'Услуга')
User = models.ForeignKey('User', blank=True, null=True,
verbose_name = 'Пользователь', related_name='SoldService')
ValidFrom = models.DateTimeField(default=datetime.today(),
verbose_name = u"Активный с")
ValidTo = models.DateTimeField(verbose_name = u"Активный до")
State = models.CharField(default='ACT', max_length=3, choices =
state_choices , verbose_name="Состояние")
admin.py:
class SoldServicesInline(admin.TabularInline):
model = SoldServices
class UserAdmin(admin.ModelAdmin):
inlines = [SoldServicesInline]
When I'm trying to save the User model with Admin interface, it
through an error like Service and ValidTo should be set for all non
filled feelds in inline form.
How can I prevent this behavior? I need possibility to add new inlines
(I can't set extra=0), but I don't want to add this every time, and
this behavior looks strange to me.
When I change to blank=True, null=True, it create blank Sold services
as soon as I save the User which is not acceptable also.
