*使用电子邮件注册用户（未经验证）和密码

目标：注册后用我自己的权利更改django-allauth的自动生成的用户名。

问题：我不确定信号是否正常工作，或者我的代码有问题，但是我无法使用自己的名称更改自动生成的django allauth用户名。我还在这里发布了尝试的各种迭代（注释）。这些只是最近几天我的代码的众多迭代和尝试中的极少数。到目前为止，我已经花费了整个星期五和星期六的时间来实现这一目标。我已经引用了以下资源，并试图模仿或使它们适应我的用例，但没有成功。

您应该使用pre_save保存用户名，并且可以通过更方便的方式进行操作，这里我可以为您提供生成用户名的功能

def unique_username_generator(instance, new_username=None):

    #user_str = get_first_name(instance.name)

    #In your case
     user_str = instance.username 

    if new_username is not None:
        username = new_username

    else:
        user_num = random.randint(1,391020931223)
        username = '{user_str}_{user_num}'.format(user_num=user_num,
                    user_str=user_str)

    klass = instance.__class__

    qs_exists = klass.objects.filter(username=username).exists()
    if qs_exists:
        user_num = random.randint(1,391020931223)
        new_username = '{user_str}_{user_num}'.format(user_num=user_num,
                    user_str=user_str)
        return unique_username_generator(instance,new_username=new_username)

    return username

在模型中对其进行编辑并使用您自己的方法来生成用户名

def username_pre_save_receiver(sender, instance, *args, **kwargs):
    if not instance.username:
        instance.username = unique_username_generator(instance)

pre_save.connect(username_pre_save_receiver, sender=User)

django allauth user_signed_up信号不起作用
