Formulaire pour lien "ForeignKey" / Django
Bonjour,
J'ai un modèle de données qui imbrique plusieurs "models.ForeignKey".
Comment faire un formulaire pour permettre la création/modification d'un élément de type "Trade" ?
Un Trade contient des phases. Les phases contiennent des conditions et des actions.
Comment faire un formulaire pour creer/modifier un Trade ?
Trade
-- Phase(s)
---- PhaseCondition(s)
---- PhaseAction(s)
Mon modèle est le suivant :
