Django：我无法在网站上显示从数据库中搜索到的信息

Question

I'm setting up a user registration / login / search program and when I try to find users by email and show them on the site it's like they do not find it in the database, but it's there. 我正在设置用户注册/登录/搜索程序，当我尝试通过电子邮件查找用户并将其显示在网站上时，就像他们在数据库中找不到该用户一样，但是它在那里。

I can not figure out what I'm doing wrong. 我不知道我在做什么错。 Can someone point me in the right direction? 有人可以指出我正确的方向吗？ Thank you in advance! 先感谢您！

This part of the code makes no sense: 这部分代码没有意义：

    email = MyUser(email = request.GET['email'], nome = request.GET['nome'])
    myusers = MyUser.objects.filter(email__contains = 'email')

maybe you meant something like: 也许你的意思是这样的：

myusers = MyUser.objects.filter(email__contains = request.GET['email'])
