Django - Inline formset - Jak nastavit aktuální uživatel

-Cíl- Potřebuji nastavit v Inline Formset, aktuální uživatel, jako je automatické obsah pole formuláře. (V současné době nefunguje)

Verze Python 3.9.2 - Django 3.2

Souvislosti: Vytvořil jsem Seznam, kde jsem si některé objekty(Záhlaví). Ze seznamu můžete vytvořit nové záhlaví a přístup k detailu-page(Detailview)pro každý z těchto pomocí cizí klíč(nazvaný podle PK-primární klíč).

Na této stránce vidím, že více informací o 1 konkrétní záhlaví. Každá hlavička může mít více řádků informací, které musí být spojeny. Řádky jsou vytvořeny nebo aktualizovány s (max 4 různé) konkrétní Inline Formsets.

-Vydání a Chyby- Jsem vytvořil tvary, které jsou správně vykreslen, ale potřebuji nastavit pro každý řádek, pole, které se automaticky dostane "aktuálního uživatele", neboť její obsah. Nemůžu zachránit a získat místo"Uživatel nemůže být null".

Jsem schopen najít řešení a zkoušel mnoho věcí, ale uvízl s touto chybou.

Laskavě ocení jakoukoli pomoc, jak tento problém vyřešit. Díky předem,

Níže nějaký kód:
