+Eboutic
+=======
+
+# Aperçu général
+
+L'application eboutic contient les vues, les templates et les modèles
+nécessaires pour le fonctionnement de la boutique en ligne.
+L'utilisateur peut acheter des produits en ligne et payer soit 
+par carte bancaire soit avec l'argent qu'il possède sur son compte AE.
+
+On effectue ici une séparation entre plusieurs types de produits : 
+- les recharges de compte (``Refilling``) qui permettent de rajouter de 
+l'argent sur le compte. Un panier contenant un élément de ce type ne pourra être
+payé que par carte bancaire.
+- Les cotisations (``Subscription``) qui permettent à un utilisateur de cotiser
+à l'AE. Seul un utilisateur ayant déjà été cotisant pourra acheter ce produit.
+Les primo-cotisants doivent s'adresser directement à un membre du bureau.
+- Les produits normaux (badges, écussons, billets pour les soirées...)
+
+Les utilisateurs cotisants ne peuvent pas voir les produits des non-cotisants
+et vice-versa. Ce n'est pas la manière la plus satisfaisante de procéder, mais
+c'est celle qui touchait le moins aux tables déjà en place.
+Les produits avec une limite d'âge ne seront pas visibles par les utilisateurs ayant
+un âge inférieur.
+
+Le comportement de cette application dépend directement de celui des applications
+``core`` et ``counter``. Les modèles de l'application ``Subscription`` sont
+également utilisés. N'hésitez donc pas à vous pencher sur le fonctionnement des modules
+susnommés afin de comprendre comment celui-ci marche.
+
+# Les vues
+
+Cette application contient les vues suivantes : 
+
+- `eboutic_main` (GET) : la vue retournant la page principale de la boutique en ligne.
+Cette vue effectue un filtrage des produits à montrer à l'utilisateur en
+fonction de ce qu'il a le droit d'acheter.
+Si cette vue est appelée lors d'une redirection parce qu'une erreur 
+est survenue au cours de la navigation sur la boutique, il est possible
+de donner les messages d'erreur à donner à l'utilisateur dans la session 
+avec la clef ``"errors"``.
+- ``payment_result`` (GET) : retourne une page assez simple disant à l'utilisateur
+si son paiement a échoué ou réussi. Cette vue est appelée par redirection
+lorsque l'utilisateur paye son panier avec son argent du compte AE.
+- ``EbouticCommand`` (POST) : traite la soumission d'un panier par l'utilisateur.
+Lors de l'appel de cette vue, la requête doit contenir un cookie avec l'état
+du panier à valider. Ce panier doit strictement être de la forme : 
+```
+[
+  {"id": <int>, "name": <str>, "quantity": <int>, "unit_price": <float>},
+  {"id": <int>, "name": <str>, "quantity": <int>, "unit_price": <float>},
+  <etc.>
+]
+```
+Si le panier est mal formaté ou contient des valeurs invalides, 
+une redirection est faite vers `eboutic_main`.
+- ``pay_with_sith`` (POST) : paie le panier avec l'argent présent sur le compte
+AE. Redirige vers `payment_result`.
+- ``ETransactionAutoAnswer`` (GET) : vue destinée à communiquer avec le service 
+de paiement bancaire pour valider ou non le paiement de l'utilisateur.
+
+# Les templates
+
+- ``eboutic_payment_result.jinja`` : très court template contenant juste
+un message pour dire à l'utilisateur si son achat s'est bien déroulé.
+Retourné par la vue ``payment_result``.
+- ``eboutic_makecommand.jinja`` : template contenant un résumé du panier et deux
+boutons, un pour payer avec le site AE et l'autre pour payer par carte bancaire.
+Retourné par la vue ``EbouticCommand``
+- ``eboutic_main.jinja`` : le plus gros template de cette application. Contient
+une interface pour que l'utilisateur puisse consulter les produits et remplir
+son panier. Les opérations de remplissage du panier se font entièrement côté client.
+À chaque clic pour ajouter ou retirer un élément du panier, le script JS
+  (AlpineJS, plus précisément) édite en même temps un cookie. 
+Au moment de la validation du panier, ce cookie est envoyé au serveur pour
+vérifier que la commande est valide et payer.
+
+# Les modèles
+
+- ``Basket`` : représente le panier d'un utilisateur. Un objet ``Basket`` est créé
+quand l'utilisateur soumet son panier et supprimé quand le paiement est validé.
+Si le paiement n'est pas validé, le panier est conservé en base de données
+afin d'avoir une trace si l'utilisateur a quand même été débité et qu'il n'a pas
+reçu ses produits à cause d'une erreur de synchronisation.
+- ``Invoice`` : Un peu comme un panier, mais pour quand une transaction
+a été validée.
+- ``AbstractBaseItem`` : modèle utilisé pour être hérité par ``BasketItem`` et ``InvoiceItem``.
+Me demandez pas pourquoi ``product_id`` est un IntegerField plutôt qu'une clef étrangère,
+moi aussi je trouve ça complètement con. 
+Le prix unitaire est indiqué dans ce modèle même si ça fait une redondance avec le modèle
+``Product`` afin de garder le prix que l'élément avait au moment de sa vente,
+même si le prix du produit de base est modifié.
+- ``BasketItem`` : représente un élément présent dans le panier de l'utilisateur.
+- ``InvoiceItem`` : représente un élément vendu.

+class BasketForm:
+    """
+    Class intended to perform checks on the request sended to the server when
+    the user submits his basket from /eboutic/
+
+    Because it must check an unknown number of fields, coming from a cookie
+    and needing some databases checks to be performed, inheriting from forms.Form
+    or using formset would have been likely to end in a big ball of wibbly-wobbly hacky stuff.
+    Thus this class is a pure standalone and performs its operations by its own means.
+    However, it still tries to share some similarities with a standard django Form.
+
+    Example:
+        ::
+
+            def my_view(request):
+                form = BasketForm(request)
+                form.clean()
+                if form.is_valid():
+                    # perform operations
+                else:
+                    errors = form.get_error_messages()
+
+                    # return the cookie that was in the request, but with all
+                    # incorrects elements removed
+                    cookie = form.get_cleaned_cookie()
+
+    You can also use a little shortcut by directly calling `form.is_valid()`
+    without calling `form.clean()`. In this case, the latter method shall be
+    implicitly called.
