python - AttributeError：“CharField”对象没有属性“编码”Django

问题描述

我正在构建一个smtp邮件工具，最近遇到了属性错误。我真的很感谢有人帮我修复这个错误。这是我的代码。

视图.py

class HomePageView(FormView):
    form_class = ToolsForm
    template_name = 'tools/home.html'
    success_url = reverse_lazy('success')

    def form_valid(self, ToolsForm):
        ''' This method is called when valid form data has been posted '''
        ToolsForm.send_email()
        return super().form_valid(ToolsForm)

表格.py

class ToolsForm(forms.Form):
    sender_mail = forms.CharField(required=True,
                                    widget=forms.EmailInput(attrs={'placeholder': 'Enter your mail account here:'}))
    receiver_mail = forms.CharField(required=True,
                                     widget=forms.EmailInput(attrs={'placeholder': 'Enter your mail account here:'}))
    subject = forms.CharField(max_length=100, required=True,
                              widget=forms.TextInput(attrs={'placeholder': 'Enter the subject here:'}))
    message = forms.CharField(required=True, max_length=200,
                           widget=forms.TextInput(attrs={'placeholder': 'Enter your body text here'}))
    password = forms.CharField(widget=forms.PasswordInput(attrs={'placeholder': 'Enter your password here'}))

    def send_email(self):
        sender = self.cleaned_data.get("sender_mail")
        receiver = self.cleaned_data.get("receiver_mail")
        subject = self.cleaned_data.get("subject")
        message = self.cleaned_data.get("message")
        password = self.cleaned_data.get("password")

        send_mail(subject, message, sender, [receiver], auth_password=password)

错误

    new_conn_created = self.open()

解决方案

问题：问题出在views.py文件中。在引用send_mail()函数之前，我忘记创建该类的实例。

解决方案：通过form_class访问该方法可能有效，但我没有尝试过。所以我创建了一个ToolsForm类的实例并调用了send_mail()方法。
