+Application Food
+================
+
+L'application ``food`` s'occupe de la traçabilité et permet notamment l'obtention de la liste des allergènes.
+
+Modèles
+-------
+
+L'application comporte 5 modèles : Allergen, QRCode, Food, BasicFood, TransformedFood.
+
+Food
+~~~~
+
+Ce modèle est un PolymorphicModel et ne sert uniquement à créer BasicFood et TransformedFood.
+
+Le modèle regroupe :
+
+* Nom du produit
+* Propriétaire (doit-être un Club)
+* Allergènes (ManyToManyField)
+* date d'expiration
+* a été mangé (booléen)
+* est prêt (booléen)
+
+BasicFood
+~~~~~~~~~
+
+Les BasicFood correspondent aux produits non modifiés à la Kfet. Ils peuvent correspondre à la fois à des produits achetés en magasin ou à des produits Terre à Terre. Ces produits seront les ingrédients de tous les plats préparés et en conséquent sont les seuls produits à nécessité une saisie manuelle des allergènes.
+
+Le modèle regroupe :
+
+* Type de date (DLC = date limite de consommation, DDM = date de durabilité minimale)
+* Date d'arrivée
+* Champs de Food
+
+TransformedFood
+~~~~~~~~~~~~~~~
+
+Les TransformedFood correspondent aux produits préparés à la Kfet. Ils peuvent être composés de BasicFood et/ou de TransformedFood. La date d'expiration et les allergènes sont automatiquement mis à jour par update (qui doit être exécuté après modification des ingrédients dans les forms par exemple).
+
+Le modèle regroupe :
+
+* Durée de consommation (par défaut 3 jours)
+* Ingrédients (ManyToManyField vers Food)
+* Date de création
+* Champs de Food
+
+Allergen
+~~~~~~~~
+
+Le modèle regroupe :
+
+* Nom
+
+QRCode
+~~~~~~
+
+Le modèle regroupe :
+
+* nombre (unique, entier positif)
+* food (OneToOneField vers Food)
+
+Création de BasicFood
+~~~~~~~~~~~~~~~~~~~~~
+
+Un BasicFood a toujours besoin d'un QRCode (depuis l'interface web). Il convient donc de coller le QRCode puis de le scanner et de compléter le formulaire.
+
+Création de TransformedFood
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Pour créer un TransformedFood, il suffit d'aller dans l'onglet ``traçabilité`` et de cliquer sur l'onglet.
+
+Ajouter un ingrédient
+~~~~~~~~~~~~~~~~~~~~~
+
+Un ingrédient a forcément un QRCode. Il convient donc de scanner le QRCode de l'ingrédient et de sélectionner le produit auquel il doit être ajouté.
+
+Remarque : Un produit fini doit avoir un QRCode et inversement.
+
+Terminer un plat
+~~~~~~~~~~~~~~~~
+
+Il suffit de coller le QRCode sur le plat, de le scanner et de sélectionner le produit.
