Question

有人知道为什么以下表格没有验证：

forms.py：

class UserRegistrationForm(UserCreationForm):
    required_css_class = 'required'
    username = forms.CharField(label='Username')
    email = forms.EmailField(label='Email')
    password = forms.CharField(label='Password')
    password2 = forms.CharField(label='Password2')

    class Meta:
        model = User
        fields = ('first_name', 'last_name', 'username', 'email')

    def __init__(self, *args, **kwargs):
        super(UserRegistrationForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget = TextInput(attrs={'placeholder': 'Username'})
        self.fields['username'].required = True
        self.fields['username'].error_messages = {'required': 'Please enter your username'}

        self.fields['email'].widget = EmailInput(attrs={'placeholder': 'Email'})
        self.fields['email'].required = True
        self.fields['email'].error_messages = {'required': 'Please enter your email'}

        self.fields['first_name'].widget = TextInput(attrs={'placeholder': 'Forename'})
        self.fields['first_name'].required = True
        self.fields['first_name'].error_messages = {'required': 'Please enter your first name'}

        self.fields['last_name'].widget = TextInput(attrs={'placeholder': 'Surname'})
        self.fields['last_name'].required = True
        self.fields['last_name'].error_messages = {'required': 'Please enter your last name'}

        self.fields['password'].widget = PasswordInput(attrs={'placeholder': 'Password'})
        self.fields['password'].required = True
        self.fields['password'].error_messages = {'required': 'Please enter your Password'}

        self.fields['password2'].widget = PasswordInput(attrs={'placeholder': 'Confirm password'})
        self.fields['password2'].required = True
        self.fields['password2'].error_messages = {'required': 'Please confirm your Password'}

    def cleaned_username(self):
        username = self.cleaned_data.get('username')
        username_qs = User.objects.filter(username=username)
        if username_qs.exists():
            raise forms.ValidationError("I'm sorry, that username already exists.")

    def cleaned_email(self):
        email = self.cleaned_data.get('email')
        email_qs = User.objects.filter(email=email)
        if email_qs.exists():
            raise forms.ValidationError("I'm sorry, this email has already been taken.")

    def cleaned_password2(self):
        password = self.cleaned_data.get('password')
        password2 = self.cleaned_data.get('password2')

        if password != password2:
            raise forms.ValidationError("Your passwords do not match.")

templates.html：

<form class="contact-form" name="contact-form" method="POST" action="." enctype='multipart/form-data'>
  <div class="form-group">
  {% csrf_token %}
  <input class="form-control" type="text" name="{{ form.first_name.name }}" {% if form.first_name.value %}value="{{ form.first_name.value }}"{% endif %} placeholder="Forename"/>
  {% if form.firstname.errors %}<span class="form-error error-above">{{ form.first_name.errors.as_text }}</span>{% endif %}
  <input class="form-control" type="text" name="{{ form.last_name.name }}" {% if form.last_name.value %}value="{{ form.last_name.value }}"{% endif %} placeholder="Surname"/>
  {% if form.lastname.errors %}<span class="form-error error-above">{{ form.last_name.errors.as_text }}</span>{% endif %}
  <input class="form-control" type="text" name="{{ form.username.name }}"    {% if form.username.value %}value="{{ form.username.value }}"{% endif %} placeholder="Username"/>
  {% if form.username.errors %}<span class="form-error error-above">{{ form.username.errors.as_text }}</span>{% endif %}
  <input class="form-control" type="text" name="{{ form.email.name }}" {% if form.email.value %}value="{{ form.email.value }}"{% endif %} placeholder="Email"/>
  {% if form.email.errors %}<span class="form-error error-above">{{ form.email.errors.as_text }}</span>{% endif %}
  <input class="form-control" type="password" name="{{ form.password.name }}" {% if form.password.value %}value="{{ form.password.value }}"{% endif %} placeholder="Password"/>
  {% if form.password.errors %}<span class="form-error error-above">{{ form.password.errors.as_text }}</span>{% endif %}
  <input class="form-control" type="password" name="{{ form.password2.name }}" {% if form.password2.value %}value="{{ form.password2.value }}"{% endif %} placeholder="Confirm Password"/>
  {% if form.password2.errors %}<span class="form-error error-above">{{ form.password2.errors.as_text }}</span>{% endif %}
  <button type="submit" class="btn btn-primary" value='{{ title }}'>Sign Up</button>
</form>

表单只是没有验证 - 我想它可能与templates.html有关，但很难确切地知道没有错误被抛回。我确定根据我定义的控制流程，我输入的细节都是正确的。

views.py：

def register(request):
    title = "Register"
    if request.method == 'POST':
        form = UserRegistrationForm(request.POST or None)
        if form.is_valid():
            print("The form is valid!")
            user = form.save(commit=False)
            user_passsword = form.cleaned_data.get('password')
            user.set_password(user_password)
            user.save()

            return render(request, 'blog/post/list.html', { 'user': user, 'title': title })
    else:
        print("The form is not valid!")
        form = UserRegistrationForm()

    return render(request, 'oauth/user/registration_form.html', { 'form': form, 'title': title })

请帮忙！我只是不知道我哪里出错了 - 我尝试的一切似乎都给了我＆＃34;表格无效！＆＃34;在终端 - 我无法验证这种形式。我错过了什么？（它必须是显而易见的）:(

尝试一次

def register(request):
    title = "Register"
    if request.method == 'POST':
        form = UserRegistrationForm(request.POST or None)
        if form.is_valid():
            print("The form is valid!")
            user = form.save(commit=False)
            user_passsword = form.cleaned_data.get('password')
            user.set_password(user_password)
            user.save()

            return render(request, 'blog/post/list.html', { 'user': user, 'title': title })
        else:
            print("The form is not valid!")
    else:
        form = UserRegistrationForm(request.POST)
    return render(request, 'oauth/user/registration_form.html', { 'form': form, 'title': title })

模板中的

  <div class="form-group">

Django注册视图没有验证表单？
