Question

我创建了一个Django应用程序。该应用程序具有用户注册页面。注册页面已实施，我正在尝试在注册后实施电子邮件确认。即在用户注册时发送电子邮件。在这样做时我遇到了这个错误，“'str'对象不支持项目分配”。有人可以帮我解决这个问题。将粘贴我的代码。

def registrationForm(request):
    if request.method == "POST":  
        firstName = request.POST.get("firstName")
        lastName = request.POST.get("lastName")
        email = request.POST.get("email")
        password = request.POST.get("password")
        sex = request.POST.get("sex")
        birthday = request.POST.get("birthday")
        print request.POST.get("sex")
        UniversityDetails(firstName=firstName,lastName=lastName,email=email,password=password,sex=sex,birthday=birthday).save()

        msg = "Registration Successfull"
        msg['Subject'] = 'The contents of %s' 
        msg['From'] = me
        msg['To'] =you 
        s = smtplib.SMTP()
        s.sendmail(me, [you], msg.as_string())
        s.quit()

        return render_to_response('registrationForm.html')

    return render_to_response("registrationForm.html")

HTML

<script type="text/javascript">

    if  ((document.myform.firstName.value.length==0)) 
        {
        document.getElementById('firstNameID').innerHTML = 'Please fill this field';
        return true;
        }
    else if ((document.myform.password.value.length==0)) 
        {
        document.getElementById('passwordID').innerHTML = 'Please fill this field';
        return true;
        }
    else if (! ValidCaptcha())
        {txtCaptcha
            alert("Captcha entered wrong");
        }

    else 
        { 
        document.getElementById('FormID').action = "http://10.1.0.90:8080/registrationForm/";
        document.getElementById('FormID').submit();
        return false; 
        }
}

Answer 1

问题在于：

msg = "Registration Successfull"
msg['Subject'] = 'The contents of %s'

string是不可变的，不像dict一样。你也应该使用Django Forms，而不是自己动手。

Django还内置支持发送电子邮件。阅读Sending E-mail documentation以了解如何使用它。
