Question

我正在尝试建立一个用户个人资料页面，用户可以在其中管理他们订阅的“客户”。出于测试目的，我在模板中调用整个表单{{customer_subscription}}，它正在返回用户的正确实例，但我希望它还可以在表单实例上突出显示该用户的订阅“客户”但它没有选择任何东西。我做错了什么？

models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=10, blank=True)

    def __unicode__(self):
        return self.user.username

class Customers(models.Model):
    customer = models.CharField(max_length=200)

    def __unicode__(self):
        return self.customer

class Customer_Subscription(models.Model):
    user = models.ForeignKey(User)
    customers = models.ManyToManyField('Customers')
    def __unicode__(self):
        return (self.user)

forms.py

class CustomerSubscriptionForm(forms.ModelForm):
    class Meta:
        model = Customer_Subscription
        fields = '__all__'

views.py

def profile(request):

    userprofile = UserProfile.objects.get(user=request.user)
    customer_subscription = CustomerSubscriptionForm(instance=userprofile)
    return render_to_response('profile.html', {'userprofile' : userprofile, 'customer_subscription':customer_subscription, },context_instance=RequestContext(request))

创建ModelForm时，必须使用CustomerSubscription对象实例而不是UserProfile

def profile(request):
    userprofile = UserProfile.objects.get(user=request.user)
    customer_subs = CustomerSubscription.objects.get(user=userprofile)
    customer_subscription = CustomerSubscriptionForm(instance=customer_subs)
    return render_to_response('profile.html', {'customer_subscription' : customer_subscription, 'customer_subscription':customer_subscription, },context_instance=RequestContext(request))

Django Form实例无法正常工作
