Django erreur SSL

Question

Je semble obtenir cette erreur, et je ne sais pas comment le déboguer. Des pointeurs?

Answer 1

De l'apparence de celui-ci, je dirais que la connexion à Rackspace CloudFiles a expiré. Imagekit construit dynamiquement les vignettes (ce que je crois qu'il faisait ici en _create()) mais il y a aussi une option pour créer toutes les vignettes quand le modèle est sauvegardé plutôt que pendant le rendu. Cela ne vous aidera pas vraiment si Rackspace tombe en panne, mais cela vous aidera à réduire le temps nécessaire au rendu de vos modèles.

EDIT: Pour effectuer une pré-cache ongle du pouce que vous modifiez votre définition ImageSpec d'inclure pre_cache = True tels que (du imagekit wiki):

from imagekit.specs import ImageSpec 

class Thumbnail(ImageSpec): 
    access_as = 'thumbnail_image' 
    pre_cache = True 

Si vous changez vos spécifications, vous pouvez reconstruire tous les mises en cache des vignettes avec la commande de gestion ikflush. Vous devriez noter que, bien que cela va créer toutes les vignettes où pre_cache = True cela va également supprimer toutes les images en cache où pre_cache = False.

Je suis l'auteur de django-cumulus. Cloud Files est connu pour les problèmes de connexion SSL. django-cumulus a un paramètre (ajouté en 0.3.6) appelé CUMULUS_TIMEOUT qui a par défaut 5 secondes. Vous pouvez l'augmenter à 10 ou 15 pour essayer d'atténuer cela.

Voir https://github.com/richleland/django-cumulus/issues/5 pour plus d'informations et n'hésitez pas à poster un problème si vous continuez à rencontrer des problèmes.
