Si estas usando ajax lo que puedes hacer es instalarte django rest framework o crearte una vista que cuando sea get te retorne los datos de la db y cuando sea post los actualice y puedes llamarla desde ajax una primera vez cuando se ejecuta el formulario para rellenarlo y luego cada vez que se hace submit hacer un preventdfault y llamar a la vista por ajax con un método post y si es exitoso llamar con uk get para actualizar el form.
