Question

这是我的观点：

def registerView(request):
    form = RegistrationForm()

    if request.method == 'POST':
        form = RegistrationForm(request.POST)

    if form.is_valid():
        user = User.objects.create_user(
            username=form.cleaned_data['username'],
            password=form.cleaned_data['password1'],
            email=form.cleaned_data['email']
        )

        username=form.cleaned_data['username']
        password=form.cleaned_data['password1']
        user = authenticate(username=username, password=password)
        login(request, user)
        return redirect('/home/') 

    variables = {'registerForm':form}
    return render(request, 'register.html', variables)

这是我的RegistrationForm：

class RegistrationForm(forms.Form):

    username = forms.CharField(label='Username', max_length=30)
    email = forms.EmailField(label='Email')
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput()) 
    password2 = forms.CharField(label='Confirm Password', widget=forms.PasswordInput()) 

def clean_password2(self):
    if 'password1' in self.cleaned_data:
        password1 = self.cleaned_data['password1']
        password2 = self.cleaned_data['password2']
        if password1 == password2:
        return password2
    raise forms.ValidationError('Passwords do not match.')

def clean_username(self):
    username = self.cleaned_data['username']
    if not re.search(r'^\w+$', username):
        raise forms.ValidationError('Username can only contain alphanumeric characters and the underscore.')
    try:
        User.objects.get(username=username) 
    except ObjectDoesNotExist:
        return username 
    raise forms.ValidationError('Username is already taken.')

这是我的模板：

<form method="post" action="/regsiter/">{% csrf_token %}
    <h6>username:</h6>
    {{ registerForm.username }}

    <h6>email</h6>
    {{ registerForm.email }}

    <h6>password:</h6>
    {{ registerForm.password1 }}

    <h6>confirm password:</h6>
    {{ registerForm.password2 }}

    <input type="hidden" name="next" />
    <input type="submit" value="register" />
</form>

现在由于某种原因，当我转到我的模板并且没有填写任何内容（将所有字段留空）并尝试注册时，它会重定向到/ home /，这意味着它将表单标记为有效（如果form.is_valid （）：由于某种原因返回true）即使所有字段都是空白。我甚至尝试使用存在的用户名，但它仍然表示该表单有效。知道为什么吗？

表单操作拼写错误，因此从未触及registerView。它应该是：

<form method="post" action="/register/">

Form.is_valid（）在不应该返回时返回true？
