Question

您是否有提示为什么验证码不显示？

from captcha.fields import CaptchaField

class ResponseForm(models.ModelForm):

    captcha = CaptchaField() # added this according to documentation

    class Meta:
        model = Response
        fields = ['comments']

    def __init__(self, *args, **kwargs):
        [...]

    def save(self, commit=True):
        [...]

它在这里工作：

from captcha.fields import CaptchaField

class UserCreationForm(UserCreationFormBase):

    email = forms.EmailField(
        label='Email',
        error_messages={'invalid': 'Check email address!'})

    captcha = CaptchaField() # works fine here

    class Meta:
        model = User
        fields = ('username', 'email', 'password1', 'password2')

    def get_credentials(self):
        [...]

是因为功能def __init__和/或def save吗？

行为是没有显示验证码字段，并且表单在点击提交时不执行任何操作。如果代码中没有captcha，它就可以正常工作。

更新

没有错误消息。似乎页面再次加载。
