Question

我尝试在注册时保存两个表单。我可以看到auth表单保存，但第二个表单没有通过.is_valid（）。你能告诉我什么是错的吗？

Models.py

class School(models.Model):
    id = models.IntegerField(primary_key=True)
    Name = models.CharField(max_length=50, null=False)
    Domain = models.CharField(max_length=50, null=False)
    Mascot = models.ImageField(null=True, upload_to='mascot')

    def delete(self, *args, **kwargs):
        self.Mascot.delete()
        super(School, self).delete(*args, **kwargs)

    def __str__(self):
        return self.Name

class HeepooUser(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=15, null=True)
    allow_phone = models.BooleanField(default=False)
    school_id = models.IntegerField()
    date_join = models.DateTimeField(auto_now_add=True)

forms.py

class UserForm(forms.ModelForm):
    email = forms.EmailField(max_length=50, required=True)
    password = forms.CharField(widget=forms.PasswordInput())

    class Meta:
        model = User
        fields = ('email', 'password')


class RegisterForm(forms.ModelForm):
    school_id = forms.ModelChoiceField(queryset=School.objects.all())
    phone = forms.CharField(max_length=15, min_length=10, required=False)

    class Meta:
        model = HeepooUser
        fields = ('phone', 'school_id')

views.py

def register(request):
    registered = False
    if request.method == 'POST':
        user_form = UserForm(request.POST)
        profile_form = RegisterForm(request.POST)

        if user_form.is_valid() and profile_form.is_valid():
            user = user_form.save(commit=False)
            user.set_password(user.password)
            user = user_form.save()

            profile = profile_form.save(commit=False)
            profile.user = user
            profile = profile_form.save()

            registered = True
        else:
            return HttpResponse('Wrong access1')
    else:
        user_form = UserForm()
        profile_form = RegisterForm()

    return render(request, "register.html", {
        'user_form': user_form,
        'profile_form': profile_form,
        'registered': registered,
    })

我尝试将电子邮件和密码保存到auth_user和school_id，并将电话保存到单独的表格中。

一切顺利！

问题在于二进制AND的工作原理。如果user_form.is_valid（）返回False，则“if”语句将整个语句标记为False，而无需评估profile_form.is_valid（）。因此，profile_form.is_valid（）永远不会被调用，它的错误dict将不会被填充。不幸的是，django的形式is_valid（）不仅仅返回一个布尔值，并且具有填充错误字典的副作用。

if user_form.is_valid() and profile_form.is_valid():
    ...

你可以做的一件事是这样的：

user_valid = False
if user_form.is_valid():
   user_valid = True

profile_valid = False
if profile_form.is_valid():
   profile_valid = True

if user_valid and profile_valid:
   ... do something

以上确保两种表格都得到处理。可能有更好的表达方式，但这就是想法。

测试了您的代码以及我在提交表单时遇到的内容

school_id value must be an integer

我建议将school_id / school设置为学校模型的外键

class HeepooUser(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=15, null=True)
    allow_phone = models.BooleanField(default=False)
    school_id = models.ForeignKey(School)
    date_join = models.DateTimeField(auto_now_add=True)

这样我们就可以像这样做

class RegisterForm(forms.ModelForm):
    class Meta:
        model = HeepooUser
        exclude = ('allow_phone', 'user')

我认为您不需要为UserForm指定表单字段，因为默认情况下django用户只需要密码，用户名和电子邮件

报名表保存
