file validator - validating file with mime and magic numbers

[Reza Shakeri]

I want to add a file validator to Django using the native Python library called mimetypes ​https://docs.python.org/3/library/mimetypes.html
There is a file validator in Django, but it only validates files using the extension, which is not very reliable. According to the documentation, I wrote a file validator that checks the magic numbers (mimes) of the files In addition to file extensions, and it is more reliable and reliable with It supports the use of native Python libraries and many mimes, This file validator can check the size of files in addition to mimes and validate both of them.

I wrote a file validator library using Python, which you can use using the link below and see its codes:

Hi Reza.

You've marked this as a new feature, so I guess you want to include this in core. I'll say no at first pass, since complicating the built-in validators isn't really on the agenda.
Folks are very able to create their own, as you've done here. There'd need to be a consensus to include more logic here via a discussion on the DevelopersMailingList.

You can also tell folks about your validator on the ​Show & Tell category on the Django Forum. (More generally see TicketClosingReasons/UseSupportChannels).

Thanks.
