简单形式无法验证 [英] Simple form not validating

问题描述

我在stackoverflow中找到了一种使用信号扩展django内置身份验证的方法。我的基础用户由电子邮件和密码定义（所以没有用户名）。所以我试图根据我的需要修改它，但是我正在为我的表单发出验证错误。奇怪的是，错误连接到User.email字段，即使我刚刚注册，我正在已经在使用。是试图保存它2次还是什么？当我发送字典时，我发送字典与shell中的表达式的构造函数： form = MyForm（data = {}）。在此表单仍然无效后，但是将电子邮件更改为不同的值终于给了我True。

I have found here on stackoverflow a method to extend django's built-in authentication using signals. My base User is defined by 'email' and passwords (so no username there). So I'm trying to modify it to my needs, but I'm geting a validation error for my form. Strange thing is that error is connected to the User.email field and I'm getting 'already in use' even though I'm just registering at the moment. Is it trying to save it 2 times or what ? I've discovered it when I was sending dictionary with data to form's contstructor in shell: form = MyForm(data={}). After this form was still invalid, but changing email to different value finally gave me True.

将user_created函数连接到注册信号：

The user_created function connected to registration signal :

def user_created(sender, user, request, **kwargs):
    form = CustomRegistrationForm(request.POST, request.FILES)
    if form.is_valid():
        data = UserProfile(user=user)
        data.is_active = False
        data.first_name = form.cleaned_data['first_name']
        data.last_name = form.cleaned_data['last_name']
        data.street = form.cleaned_data['street']
        data.city = form.cleaned_data['city']
        data.save()
    else:
        return render_to_response('user/data_operations/error.html', {'errors': form._errors}, context_instance=RequestContext(request))

user_registered.connect(user_created)

我的表单：

class CustomRegistrationForm(RegistrationForm):
    first_name = forms.CharField(widget=forms.TextInput(attrs=attrs_dict), max_length=50)
    last_name = forms.CharField(widget=forms.TextInput(attrs=attrs_dict), max_length=50)
    street = forms.CharField(widget=forms.TextInput(attrs=attrs_dict), max_length=50)
    city = forms.CharField(widget=forms.TextInput(attrs=attrs_dict), max_length=50)

我的模型：

class UserProfile(models.Model):
    first_name = models.CharField(_("Name"), max_length=50, blank=False,)
    last_name = models.CharField(_("Last name"), max_length=50, blank=False,)
    street = models.CharField(_("Street"), max_length=50, blank=False,)
    city = models.CharField(_("City"), max_length=50, blank=False,) 
    user = models.ForeignKey(User, unique=True, related_name='profile',)

注册表单：
class RegistrationForm（forms.Form）：

Registration form : class RegistrationForm(forms.Form):

email = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict,
                                                           maxlength=75)),
                         label=_("Adres email"))
password1 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                            label=_("Haslo"))
password2 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                            label=_("Haslo powtorzone"))

def clean_email(self):
    email = self.cleaned_data.get("email")
    if email and User.objects.filter(email=email).count() > 0:
        raise forms.ValidationError(
            _(u"Already in use."))
    return email

推荐答案

您的'user_registered'信号在用户保存后发送。所以它已经定义了一个电子邮件字段。

your 'user_registered' signal is sent after the User is saved. So it already has an 'email' field defined.

更新

使用不安思考：

form = CustomRegistrationForm(request.POST, request.FILES, notvalidateemail=True)

并在表单中：

def __init__(self, *args, **kwargs):
    self.notvalidateemail = kwargs.pop('notvalidateemail',False)
    super(CustomRegistrationForm, self).__init__(*args, **kwargs)

def clean_email(self):
    if self.notvalidateemail:
        return
    else:
        #your cleaning here
        return email
