我创建一个用户配置文件如下：
class UserProfile(models.Model):
# This field is required:
user = models.OneToOneField(User, related_name="User can view study permission")
# Other fields:
phone = models.CharField(max_length=20)
disease = models.ManyToManyField(Disease)
date_assigned = models.DateTimeField("Date Assigned")
query = models.ManyToManyField(Query, blank=True)
def __unicode__(self):
studies = ', '.join(study.name for study in self.disease.all())
return "%s can view %s" % (self.user, studies)
它是用户的扩展信息。现在我正在自己创建一个管理页面，以允许管理员更新包含上述用户配置文件的用户帐户信息。其形式和代码如下：
def edit(request, user_id):
"""Edit a user's details"""
try:
user = User.objects.get(id=user_id)
except User.DoesNotExist:
user = None
# user exists:
if user:
# Initial form field data:
initial={'user_id': user_id,
'username': user.username,
'fname': user.first_name,
'lname': user.last_name,
'email': user.email,
'phone': user.get_profile().phone,
'groups': user.groups.all(),
'studies': user.get_profile().disease.all(),
'is_admin': user.is_staff,
'is_active': user.is_active
}
request.breadcrumbs(
(_("Home"), reverse('home')),
(_("All Users"), reverse('all users')),
(_("User Details"), reverse('user details', args=[user_id])),
)
if request.method == "GET":
form = UserProfileEditForm(initial=initial,extra=request.user.id)
response = {'heading': 'Edit', 'form': form}
return render_to_response('accounts/edit.html',
response,
context_instance=RequestContext(request)
)
elif request.method == "POST":
form = UserProfileEditForm(request.POST,extra=request.user.id)
if form.is_valid():
Log().add(request, "Edit", "W", "userprofile", user_id)
if form.cleaned_data['password1'] and form.cleaned_data['password2']:
user.set_password(form.cleaned_data['password1'])
user.username = form.cleaned_data['username']
user.first_name = form.cleaned_data['fname']
user.last_name = form.cleaned_data['lname']
user.email = form.cleaned_data['email']
user.groups = form.cleaned_data['groups']
user.is_staff = form.cleaned_data['is_admin']
user.is_active = form.cleaned_data['is_active']
user.save()
# Oddly to make the extra fields found in UserProfile are saved, you
# have to call get_profile().ATTRIBUTE, assign a value, then call
# get_profile().save(). Calling user.save() as the last step won't
# save any changes made to UserProfile:
disease_pks = form.cleaned_data['studies']
user.get_profile().disease = Disease.objects.filter(pk__in=disease_pks)
user.get_profile().phone = form.cleaned_data['phone']
user.get_profile().save()

如果管理员试图编辑其他用户的帐户信息，它可以正常工作。但是，当管理员尝试更新他自己的帐户时。无论此字段是否更改，疾病字段将始终为空白。
有谁知道原因以及我应该如何更改我的代码？非常感谢。
