Python Django-从自定义对象获取值
我正在使用Django为用户创建OneToOneField对象,代码如下:Python Django-从自定义对象获取值,python,django,django-models,django-forms,django-views,Python,Django,Django Models,Django Forms,Django Views,我正在使用Django为用户创建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
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)
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)
然后,我用下面的代码为这个对象创建了一个表单:
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)
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\u on\u off”)。我认为出现问题是因为我使用了
request.user.get\u profile()
。如何修改它以获取ControlInformation对象的值,然后修改并保存它?而不是ControlInformation=request.user.get\u profile()
使用:
instance = ControlInformation.objects.get(user=request.user)
更多提示:
- 使用
从模型自动创建表单ModelForm
- 您可以使用
布尔字段来代替开/关
TEMP = (
('HIGH', 'High'),
('MEDIUM', 'Medium'),
('LOW', 'Low'),
)
享受Django 您需要包含更多关于views.py的信息,因为错误引用的是问题中未定义的
UserProfile
对象。另外,您是否在设置中将appname.ControlInformation
设置为AUTH\u PROFILE\u MODULE
?
