python - Django Forms cleaned_data 缺少某些字段

Question

我使用 Django 客户用户模型为用户注册创建的表单有一个奇怪的问题。我正在运行 Django 1.6.5。

表单.py

class SignupForm(forms.ModelForm):
    password1 = forms.CharField(widget=forms.PasswordInput,
                                label=_('Password'),
                                max_length=50)
    password2 = forms.CharField(widget=forms.PasswordInput,
                                label=_('Repeat password'),
                                max_length=50)

    class Meta:
        model = RegisteredUser
        fields = ("firstname", "lastname", "email", "password1", "password2",)

    def clean_email(self):
        existing = RegisteredUser.objects.filter(email__iexact=self.cleaned_data['email'])
        if existing.exists():
            raise forms.ValidationError(_('A user with that email already exists.'))
        return self.cleaned_data['email']

    def clean(self):
        cleaned_data = super(SignupForm, self).clean()
        if 'password1' in self.cleaned_data and 'password2' in self.cleaned_data:
            if self.cleaned_data['password1'] != self.cleaned_data['password2']:
                raise forms.ValidationError(_('The two passwords did not match.'))
        return cleaned_data

View .py

class SignUpView(FormView):
    template_name = 'core/signup.html'
    form_class = SignupForm
    success_url = None

    def post(self, request, *args, **kwargs):
        form = self.get_form(self.get_form_class())
        if form.is_valid():
            return self.form_valid(request, form)
        else:
            return self.form_invalid(form)

    def form_valid(self, request, form):
        new_user = self.register(request, **form.cleaned_data)
        success_url = self.get_success_url(request, new_user)

        try:
            to, args, kwargs = success_url
            return redirect(to, *args, **kwargs)
        except ValueError:
            return redirect(success_url)



    def register(self, request, **cleaned_data):
        RegisteredUser.objects.create_user(email=cleaned_data['username'],
                                           firstname=cleaned_data['firstname'],
                                           lastname=cleaned_data['lastname'],
                                           password=cleaned_data['password2'])

表单返回无效，表示“password1”和“password2”是必填字段。该值与其他字段一起清楚地显示在发布数据中。

无论我尝试过什么，'password1' 和 'password2' 都不包含在 cleaned_data 字典中。我已经尝试为这两个字段使用各种其他名称，只是为了确保“password2”不会与其他任何内容发生冲突。

我可能忽略了一些非常简单的事情:-)

谢谢!

编辑 1 - 正在使用的模板(抱歉 div-hell!):

<section class="container">
        <div class="row">

Answer 1

这是我如何在我的项目中执行此操作的示例:

表单.py:

class NewUserForm(forms.Form):
    username = ...
    password1 = forms.CharField(widget=forms.PasswordInput, required=True)
    password2 = forms.CharField(widget=forms.PasswordInput, required=True)

    def clean_password2(self):
        password1 = self.cleaned_data.get("password1", "")
        password2 = self.cleaned_data.get("password2", "")
        if password1 and password2:  # If both passwords has value
            if password1 != password2:
                raise forms.ValidationError(_(u"Passwords didn't match."))
        else:
            raise forms.ValidationError(_(u"Passwords can't be blank."))
        return password2

views.py:

@login_required
def add_user(request):
    ''' Adds new user '''

    if request.method == 'POST':
        form = NewUserForm(request.POST)
        if form.is_valid():
            user = form.save()
            # TODO: Save in temporary table
            return HttpResponse('SUBMIT')
    else:
        form = NewUserForm()

    return render_to_response('add_user.html', {'form': form}, context_instance=RequestContext(request))

模板(表单示例):

<form action="." method="post" id="add_user_form">
{% csrf_token %}
    {{ form.username }}
    {{ form.password1 }}
    {{ form.password2 }}
    {{ form.usertype }}

    <input type="submit" value="{% trans 'Save' %}" class="default"/>

</form>

{% csrf_token %} :你需要把它放在你使用的每一个表单中

action="." :这使得发布到实际页面

{{ form.VARIABLE_NAME}} 您需要像这样设置表单的输入，在 View 中创建表单，发送到模板，并将其用作 Django 变量使用{{ }}。要为您的其中一个字段设置输入，例如 password1，就像我在上面写的那样 {{ form.password1}}，您也可以使用 {{ form.errors}} 检查所有表单错误，或 {{form.VARIABLE_NAME.errors}} 检查模板中的确切字段错误
