Hello guys, I have been wondering and looking around for examples... what is the best way to handle for validation of complex forms in Django+htmx? By "complex" i mean where for example the same form validates username length, username not in db, and profile picture (file uploaded in the same form) should not exceed say 5 MB and 4k resolution. There are some methods I have been thinking of to validate this form but I'd love to hear your ideas. (Please point to any relevant examples/tutorials if any/demos/production projects too.)
