它没有将值保存到数据库表中，为什么？

Question

def register(request):
    flag = True
    possible = '0123456789abcdefghijklmnopqrstuvwxyz'
    token = ''
    length = 10
    i = 0

    current_datetime = datetime.datetime.now()

    user = UsersModelForm()
    if request.method == 'POST':
        userf = UsersModelForm(request.POST)
        username = userf.data['username']
        password = userf.data['password']
        passwordrepeat = userf.data['passwordrepeat']
        email = userf.data['email']

        if password != passwordrepeat:
            flag = False
            passVariable = {'user':user, 'flag': False}
            return render_to_response('register.html', passVariable, context_instance=RequestContext(request))

        elif password == passwordrepeat:
            for i in range(1,10):
                temp = random.choice(possible)
                token = token + temp

            print token
            userf.email_token = token
            userf.email_token_expiry = current_datetime + timedelta(1)
            if userf.is_valid():
                check = userf.save()
            return HttpResponseRedirect('/')

userf.save() 正在插入一行，但它没有保存 email_token、email_token_expiry，它只是插入用户名、密码、电子邮件和 models.py 中的默认值。

models.py：

class Users(models.Model):
    username = models.CharField(max_length=255)
    slug = models.CharField(max_length=255, default='0')
    password = models.CharField(max_length=300)
    passwordrepeat = models.CharField('Repeat Password', max_length=300)
    password_token = models.CharField(max_length=300, default='0')
    email = models.CharField(max_length=255)
    email_verified = models.BooleanField(default=False)
    email_token = models.CharField(max_length=255)
    email_token_expiry = models.DateTimeField(auto_now_add=True)
    tos = models.BooleanField(default=False)
    active = models.BooleanField(default=False)
    last_login = models.DateTimeField(auto_now_add=True)
    last_action = models.DateTimeField(auto_now_add=True)
    is_admin = models.BooleanField(default=False)
    role = models.CharField(max_length=255, default='0')
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now_add=True)

    def __unicode__(self):
        return self.username

class UsersModelForm(forms.ModelForm):
    class Meta:
        model = Users
        fields = ('username', 'password', 'passwordrepeat', 'email')
        widgets = {
            'password' : PasswordInput(),
            'passwordrepeat' : PasswordInput(),
        }

有人可以帮我解决这个问题吗？为什么不将值保存到其他字段？

Answer 1

它只是为您在fields 中指定的字段插入值。将 email_token、email_token_expiry 添加到该列表中，这些也将保存到数据库中。

编辑：哎呀，是的。改为这样做：

check = userf.save(commit=False)
check.email_token = token
check.email_token_expiry = current_datetime + timedelta(1)
check.save()

表单对象不会保存附加的附加信息 (AFAIK)。您需要从 save() 取回对象，然后分配这些值。 commit=False 阻止表单保存到数据库。然后添加所需的额外信息并保存对象。

Answer 2

试试这个：

        if userf.is_valid():
            user = userf.save(commit=False)
            user.email_token = token
            user.email_token_expiry = current_datetime + timedelta(1)
            user.save()
