python - （Django）基于类的视图中的验证表单不起作用

问题描述

我创建了一个视图，用户可以在其中注册使用带有验证功能的表单。但是，这些功能不起作用。

class SignUpPage(View):
    def get(self, request):
        form = SignUpForm()
        return render(request, "signup.html", {'form': form})
    def post(self, request):
        form = SignUpForm(request.POST or None)
        if form.is_valid():
            redirect('/signup')
        else:
            form = SignUpForm()
        ctx = {"form": form}
        return render(request, "signup.html", ctx)

表格：

class SignUpForm(forms.Form):
    first_name = forms.CharField(max_length=32, required=True)
    last_name = forms.CharField(max_length=32, required=True)
    username = forms.CharField(max_length=32, required=True)
    email = forms.CharField(label="email")
    password1 = forms.CharField(label="Password", max_length=32, widget=forms.PasswordInput(attrs={'class': 'password'}))
    password2 = forms.CharField(label="Password Again", max_length=32, widget=forms.PasswordInput(attrs={'class': 'password'}))
    date_of_birth = forms.DateField(label="Date of birth", required=True, widget=forms.SelectDateWidget(years=YEARS, attrs={'class': 'date-select'}))

def validate_email(self):
    data = self.cleaned_data.get('email')
    if User.objects.filter(email=data).exists():
        raise forms.ValidationError("This email is already registered")
    return data

def validate_age(self):
    user_date = str(self.cleaned_data['date_of_birth'])
    year = int(user_date[0:4])
    month = int(user_date[5:7])
    day = int(user_date[8:10])
    today = dt.today()

    if int(today.year) - year < 18:
        raise forms.ValidationError("You must be 18 years old to have an account")
    elif int(today.year) - year == 18 and int(today.month) - month < 0:
        raise forms.ValidationError("You must be 18 years old to have an account")
    elif int(today.year) - year == 18 and int(today.month) - month == 0 and int(today.day) - day < 0:
        raise forms.ValidationError("You must be 18 years old to have an account")
    else:
        return user_date

有人可以解释一下为什么这些验证功能不起作用吗？我什至尝试过：

    def validate_email(self):
        data = self.cleaned_data.get('email')
        if data == "abc":
            raise forms.ValidationError("This email is already registered")
        return data

通过在输入字段中写入“abc”。

或者：

data = self.cleaned_data['email']

更多细节的 HTML 代码：

   <form action="" method="post" class="formField">
                {% csrf_token %}
                {{form}}
                <div class="s-password">
                    <input type="checkbox" class="form-checkbox" id="show-password" onclick="showPassword()">
                    <label for id="s-password">Show Password</label>
                </div>
                <div class="form-btn-wrapper">
                    <button type="submit" class="btn-form">Sign Up</button>
                    <input type="checkbox" class="form-checkbox" id="check" name="remember">
                    <label for id="remember">Remember me</label>
                </div>
                <footer class="form-footer">
                    <p>Already have an account <a href="/login">Login now</a></p>
                </footer>
</form>
