【问题描述】:
我正在尝试为用户创建一个小应用程序以建立联系人。我使用 django-profiles 作为我的个人资料的基础。现在一切正常,直到我尝试提交编辑联系表单并收到此错误。
Cannot assign "<Contact: Contact object>": "Contact.user" must be a "UserProfile" instance.
作为 Django 的新手,我什至不确定我是否在这里采用了正确的方法。我的最终目标是让用户能够根据需要添加尽可能多的联系人。 任何建议表示赞赏。
我的扩展 User 的 UserProfile 模型如下所示:
class UserProfile(models.Model):
#User's Info
user = models.ForeignKey(User, unique=True)
first_name = models.CharField("first name", max_length=30)
last_name = models.CharField("last name", max_length=30)
home_address = models.CharField(max_length=50)
primary_phone = PhoneNumberField()
city = models.CharField(max_length=50)
state = USStateField()
zipcode = models.CharField(max_length=5)
birth_date = models.DateField()
gender = models.CharField(max_length=1, choices=GENDER_CHOICES, blank=True)
我的联系人模型如下所示:
class Contact(models.Model):
user = models.ForeignKey(UserProfile)
contact_description = models.CharField("Relation or Description of Contact", max_length=50, blank=True)
contact_first_name = models.CharField("contact first name", max_length=30)
contact_last_name = models.CharField("contact last name", max_length=30)
contact_primary_phone = PhoneNumberField("contact primary phone number")
contact_secondary_phone = PhoneNumberField("contact secondary phone number",blank=True)
我的看法:
def editContact(request, username, object_id=False, template_name='contacts/edit.html'):
user = UserProfile.user
AddContactFormset = inlineformset_factory(UserProfile,Contact, extra=1)
if object_id:
contact=Contact.objects.get(pk=object_id)
else:
contact=Contact()
if request.method == 'POST':
f= ContactForm(request.POST, request.FILES, instance=contact)
fs = AddContactFormset(request.POST, instance=contact)
if fs.is_valid() and f.is_valid():
f.save()
fs.save()
return HttpResponse('success')
else:
f = ContactForm(instance=contact)
fs = AddContactFormset(instance=contact)
return render_to_response(template_name ,{'fs':fs,'f':f,'contact': contact}, context_instance=RequestContext(request))

为什么你对个人资料有一个 FK 而不是对用户本身?
