当用户在django框架中注册时，如何将默认选择值分配给用户

Question

我正在编写一个逻辑，当用户创建和帐户时，我想自动为他们分配免费会员资格，我知道这应该在register视图中完成，但我不知道为什么它没有按预期工作。我仍然需要手动转到我的管理页面，手动为新创建的用户分配一个值，这不是我真正想要的。

型号.py

class Membership(models.Model):
MEMBERSHIP_CHOICES = (
('Enterprise', 'Enterprise'), # Note that they are all capitalize//
('Team', 'Team'),
('Student', 'Student'),
('Free', 'Free')
)
PERIOD_DURATION = (
('Days', 'Days'),
('Week', 'Week'),
('Months', 'Months'),
)
slug = models.SlugField(null=True, blank=True)
membership_type = models.CharField(choices=MEMBERSHIP_CHOICES, default='Free', max_length=30)
duration = models.PositiveIntegerField(default=7)
duration_period = models.CharField(max_length=100, default='Day', choices=PERIOD_DURATION)
price = models.DecimalField(max_digits=10, decimal_places=2, default=0.00)
def __str__(self):
return self.membership_type
#### User Membership
class UserMembership(models.Model):
user = models.OneToOneField(User, related_name='user_membership', on_delete=models.CASCADE)
membership = models.ForeignKey(Membership, related_name='user_membership', on_delete=models.SET_NULL, null=True)
reference_code = models.CharField(max_length=100, default='', blank=True)
def __str__(self):
return self.user.username
@receiver(post_save, sender=UserMembership)
def create_subscription(sender, instance, *args, **kwargs):
if instance:
Subscription.objects.create(user_membership=instance, expires_in=dt.now().date() + timedelta(days=instance.membership.duration))

views.py

def register(request):
reviews = Review.objects.filter(status='published')
info = Announcements.objects.all()
categories = Category.objects.all()
if request.method == "POST":
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
username = form.cleaned_data.get('username')
obj = request.user
get_membership = Membership.objects.get(membership_type='Free')
instance = UserMembership.objects.create(user=obj, membership=get_membership)
messages.success(request, f'Account Successfully created for {username}! You can Login In Now')
return redirect('userauths:login')

elif request.user.is_authenticated:
return redirect('elements:home')
else:
form = UserRegisterForm()
context = {
'reviews': reviews,
'form': form,
'info': info,
'categories': categories
}
return render(request, 'userauths/register.html', context)

在模型中，您需要指定一个默认值="quot；属性
