Question

我是django的新手。我想开发一个注册页面，我想在其中添加姓名，电子邮件和密码字段。如果电子邮件已经存在它应该返回错误消息。为此我开发了以下代码。但它显示错误 * /中的SyntaxError 语法无效（views.py，第19行）以及其他一些

这是我的代码

forms.py *

    email=forms.EmailField(label='Email',max_length=254)

    def clean(self,*args,**kwargs):
        email=self.self.cleaned_data.get("email")
        password=self.cleaned_data.get("password")

您可能在此行中遇到问题

return render(request,"registration/signup.html",{"form":form,"title"=title})
                               # here, should be {"form":form,"title":title}

你有两次这个问题。

请尝试下次更好地格式化代码。
