Django set_password(password) doesn't hash the password
In Django documentation, it says that it hashes the password but is not saving it, so I have to save it, as I did. If I create a superuser then everything is ok, but when I try to create a user account, the password gets saved unhashed into the database. I try to use make_password, but that doesn't work either, I get the same result.

How do I sub-class a Django Model Foreign Key Field
New to Python and Django but I would like to create a custom foreign key field containing a variety of presets to use across my app. I have tried several approaches but have a variety of errors and not sure where to go from here. Goal is a 'BaseFKField' model class that has: on_delete = models.RESTRICT by default blank = False by default related names don't have the typical '_set' suffix for queries, related_name has been challenging I have tried various formulations of this: class BaseFKField(models.ForeignKey): def __init__(self, to, on_delete = None, ok_blank = None, *args, **kwargs): on_delete = models.RESTRICT kwargs['blank'] = ok_blank super().__init__(to, on_delete, blank = ok_blank, *args, **kwargs) class BaseFKField(models.ForeignKey): def __init__(self, to, on_delete=None, *args, **kwargs): super().__init__(to, on_delete, blank = False, *args, **kwargs) Also explored setting kwargs["rel"] in my ___init___ by importing ManyToOneRel and using it like they do with rel_class in the Foreign Key field class but no luck. Errors I have been getting: reverse accessor error for related_name variable set twice missing required argument In general, I am finding it very difficult to create custom fields at all. I have found the docs to be difficult to follow (the example there is very basic). I am … -

Where are captcha values usually stored?
Long story short, I made a captcha that can generate from 26letters + digits using pillow that looks cool, Now I need a way to verify that captcha value without the using of database A practical and easiest way of doing this is with sessions, It does not require read or write to the DB, But since cookies are stored on the frontend, I don't think this is a very secure way of storing the value of the captcha, I want the attacker to actually decode captcha using machine learning and not session value which I assume would be easier for the attacker to do. Is there a way to hot verify them? Even with the use of APIs it changes nothing, In this case APIs would be just like sessions and the only difference would be sending value to another function vs sending value to another url. Are there any other alternatives to where these "single use only values" are stored? Or Is there truly a way to hot verify I haven't thought of? -
