satchmo ne peut pas gérer l'erreur 500

Question

Si la quantité du produit est un caractère Unicode, j'obtiens UnicodeEncodeError à/add /. Lorsque j'ai défini DEBUG = False, le satchmo ne peut pas gérer l'erreur 500, il ne peut pas retourner un objet HttpResponse, mais le gestionnaire 404 est correct. Je trouve ce qui suit dans le journal des erreurs Apache.

Pourquoi django ne peut pas gérer la page d'erreur 500?

Answer 1

Par Django's documentation,

The default 500 view passes no variables to this template and is rendered with an empty Context to lessen the chance of additional errors

Je pense que vous devez garder la même approche pour votre 500.html, par pas extension base.html et pas référence même i18n, et garder la place qu'il aussi simple que possible.

Considérer le contexte lorsque vous obtenez une erreur de serveur: quelque chose s'est mal passé, et vous ne savez pas quoi. Vous pouvez même être dans une situation où toutes les conditions préalables habituelles ne sont pas remplies, et donc vous devriez maintenir la page aussi simple que possible.
Personnellement, je même éviter les images, en se fondant uniquement sur certains art ASCII :-)
