匹配查询不存在Django中的错误 [英] matching query does not exist Error in Django

问题描述

我已经在django中实现了密码恢复功能。使用我的方法，新密码将被发送到他输入的电子邮件ID。当我给出正确的电子邮件（数据库中存在的电子邮件ID）时，它的工作正常。但是当我给出一个不在数据库中的电子邮件ID时，它会给我这个错误'DoesNotExist at / forgotPassword /

大学详细信息匹配查询不存在。有人可以帮忙解决这个问题。将粘贴我的代码在这里。有人可以帮我解决这个问题。

forgotPassword.html（）

  def forgotPassword（request）：
 if request.POST：
 email = request.POST.get（email）
 user = UniversityDetails.objects 
如果（不是用户）：
打印没有用户
返回render_to_response（forgotPassword.html）
 else：
 newPassword = user.password 
 send_mail（'Password Recovery'，'您的网站的密码是'+新密码''[e-mail]'，
 ['[e-mail]']，fail_silently = 
返回render_to_response（passwordRecovery.html）
返回render_to_response（'forgotPassword.html'）
  

html

 < form name =forgotPasswordmethod = POSTid =myFormidaction =http://10.1.0.90:8080/forgotPassword/> 
< div style =float：center; width：100％; color：＃0000A0> 
输入您的电子邮件ID< / label>< br /> < input type =textname =emailsize =25/> 
< input type =submitvalue =提交/> 
< / div> 
 
< / form> 
  

解决方案

  try： 
 user = UniversityDetails.objects.get（email = email）
除了UniversityDetails.DoesNotExist：
 user = None 
  

我也看到你正在以明文形式存储你的密码（一个很大的安全性，不要！）。为什么不使用内置的验证系统？

I have implemented a password recovery functionality in django. With my method the new password will be sent to his email id entered. And its working fine when i give the correct email (e-mail id which exists in the database). But when i give an email id which is not in the database, it gives me this error 'DoesNotExist at /forgotPassword/

UniversityDetails matching query does not exist.'. Can somebody help to solve this. Will paste my code here. Can somebody help me to solve this problem.

forgotPassword.html()

def forgotPassword(request):
    if request.POST:
        email=request.POST.get("email")
        user = UniversityDetails.objects.get(email=email)
        if(not user):
            print "No user"
            return render_to_response("forgotPassword.html")
        else:
            newPassword = user.password
            send_mail('Password Recovery', 'The password for your site is '+ newPassword, '[e-mail]',
    ['[e-mail]'], fail_silently=False)   
            return render_to_response("passwordRecovery.html")
    return render_to_response('forgotPassword.html')

html

<form name="forgotPassword" method="POST" id="myFormid" action="http://10.1.0.90:8080/forgotPassword/">
<div style="float:center;width:100%;color:#0000A0">
 Enter your E-mail ID</label><br/> <input type="text" name="email" size="25" /> 
 <input type="submit" value="Submit" />
 </div> 

</form >

解决方案

try:
    user = UniversityDetails.objects.get(email=email)
except UniversityDetails.DoesNotExist:
    user = None

I also see you're storing your passwords in plaintext (a big security no-no!). Why don't you use the built-in auth system?
