如何在Django中通过手机号重置密码？

            # 手机号不存在于用户数据库中，给出相应提示
            return render(request, 'reset_password.html', {'error': '手机号不存在'})

        # 生成重置密码令牌
        token = default_token_generator.make_token(user)

        return render(request, 'reset_password.html', {'success': '重置密码链接已发送到您的手机号'})

    return render(request, 'reset_password.html')

            # 更新用户密码
            user.set_password(new_password)
            user.save()

            # 用户密码重置成功后，自动登录
            user = authenticate(request, username=user.username, password=new_password)
            if user is not None:
