*user registration with email(without verification) and password

Goal : Change the django-allauth's auto generated username with my own right after they signup.

Issue: I am not really sure whether the signals are not working or coming, or something wrong with my code but I am unable to change the auto generated django allauth username with my own. I have also posted the various iterations of my attempts here (commented out). These are just a very few of so many iterations and attempts of my code from last few days. I have so far spent an entire friday+saturday to achieve this. I have referred the following resources and tried to mimick or adapt them to my use case but no go.

You should use pre_save for saving username and you could do this is in more convenient way, here I can provide you my function for generating usernames

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

Edit it and use your own method for generating username, in your models

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)
