This piece of code is placed at the end of my checkout process. Once the user paid successfully, I want to check at the end, if there a discount code was used. If so, I want to remove the discount code session. When the user goes back to the event/product page, he has to type in the discount again, in case he wants to use it.



Is there a better way to first check for the session, and then delete it?



# If set, delete discount cookie

discount_code_session_name = 'discount_code_' + str(

            self.order_items_dict['event'].pk

        )

discount_code_session = request.session.get(discount_code_session_name, None)

if discount_code_session:

    del request.session[discount_code_session_name]





python django session

    Yes. It helps getting the bigger picture. Right now you're retrieving the session information name from a dict we know nothing about. Maybe changing this bit could avoid suppressing the session altogether… Who knows?

Orthoptera

Pour une classification, voir Orthoptera (classification phylogénétique). Orthoptera Romalea guttata , Orthoptera Caelifera Classification Règne Animalia Embranchement Arthropoda Sous-embr. Hexapoda Classe Insecta Sous-classe Dicondylia Infra-classe Pterygota Division Neoptera Super-ordre Orthopterodea Ordre Orthoptera Latreille, 1793 Les orthoptères ou Orthoptera (du grec orthos , droit, et ptéron , aile) sont un ordre de la classe des insectes. Ces animaux se caractérisent par des ailes alignées avec le corps. On estime à 22 000 le nombre d'espèces présentes sur la planète. La grande majorité est phytophage (qui se nourrit de végétaux) bien que plusieurs espèces soient régulièrement prédatrices. Cet ordre est scindé en deux sous-ordres : les ensifères (grillons et sauterelles) et les caelifères (criquets). Sommaire 1 Distribution 2 Description 2.1 Morphologie 2.2 Régime alimentai...

Ellipse (mathématiques)

Image
Pour les articles homonymes, voir Ellipse. L'ellipse est le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante. Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...

Quarter-circle Tiles

Image
up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form? I think this problem has to do with finding the chance any given 2x2 square has a circle, but I can't find it. expected-value share | cite | improve this question asked Nov 20 at 15:03 6minecraftninja 1 2 ...
