Permet de créer, modifier et supprimer :
|
|
- un port (add_port, edit_port, del_port)
|
|
- un switch : les vues d'ajout et d'édition font appel aux forms de creation
|
|
de switch, mais aussi aux forms de machines.forms (domain, interface et
|
|
machine). Le views les envoie et les save en même temps. TODO : rationaliser
|
|
et faire que la creation de machines (interfaces, domain etc) soit gérée
|
|
coté models et forms de topologie
|
|
- une chambre (new_room, edit_room, del_room)
|
|
- une stack
|
|
- l'historique de tous les objets cités
