我正在使用 Django 为用户创建一个 OneToOneField 对象,代码如下:
class ControlInformation(models.Model):
user = models.OneToOneField(User)
TURN_ON_OFF = (
('ON', 'On'),
('OFF', 'Off'),
)
AUTO_MANU = (
('ON', 'On'),
('OFF', 'Off'),
)
TEMP_DINNINGROOM = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
TEMP_LIVINGROOM = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
turn_on_off = models.CharField(max_length=2, choices=TURN_ON_OFF)
auto_manu = models.CharField(max_length = 2, choices=AUTO_MANU)
temp_dinningroom = models.CharField(max_length=2, choices=TEMP_DINNINGROOM)
temp_livingroom = models.CharField(max_length=2, choices=TEMP_LIVINGROOM)
#signal function: if a user is created, add control information to the user
def create_control_information(sender, instance, created, **kwargs):
if created:
ControlInformation.objects.create(user=instance)
post_save.connect(create_control_information, sender=User)
然后,我使用以下代码为该对象创建了一个表单:
class ControlInformationForm(forms.Form):
TURN_ON_OFF = (
('ON', 'On'),
('OFF', 'Off'),
)
AUTO_MANU = (
('ON', 'On'),
('OFF', 'Off'),
)
TEMP_DINNINGROOM = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
TEMP_LIVINGROOM = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
on_off = forms.ChoiceField(label="on_off", choices=TURN_ON_OFF)
auto_manu = forms.ChoiceField(label="auto_manu", choices=AUTO_MANU)
temp_dinningroom = forms.ChoiceField(label="temp_dinningroom", choices=TEMP_DINNINGROOM)
temp_livingroom = forms.ChoiceField(label="temp_livingroom", choices=TEMP_LIVINGROOM)
最后,我用
ControlInformation = request.user.get_profile()
form=ControlInformationForm(request.POST)
在views.py 中获取ControlInformation 对象的值,但它不起作用(错误:'UserProfile' 对象没有属性'turn_on_off')。我认为问题的发生是因为我使用了request.user.get_profile()
. 我如何修改它以获取 ControlInformation 对象的值,然后修改并保存()它?
