*用户注册邮箱（无需验证）和密码

目标：在 django-allauth 注册后立即用我自己的用户名更改自动生成的用户名。

问题：我不确定信号是否不起作用或是否出现，或者我的代码有问题，但我无法用自己的方式更改自动生成的 django allauth 用户名。 我还在此处发布了我尝试的各种迭代（已注释掉）。这些只是最近几天我的代码的如此多的迭代和尝试中的一小部分。到目前为止，我已经花了整个星期五+星期六来实现这一目标。 我参考了以下资源并尝试模仿或调整它们以适应我的用例，但没有成功。

你应该使用pre_save来保存用户名，你可以这样做更方便，这里我可以为你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

编辑它并使用您自己的方法在您的模型中生成用户名

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)
