Problème pour accéder à la page Admin

**Jiyuu** · 10/04/2009, 08h22

Bonjour à tous,

Je me lance dans la refonte d'un programme wxPython avec Django.
J'ai commencé par recréer mes modèles et j'ai voulu voir si tout allait bien sur le serveur de développement.

La page d'accueil fonctionne, par contre si je souhaite accéder à l'admin du site voici le message d'erreur que j'obtiens:

Essaye en plaçant l'application django.contrib.admin après django.contrib.sites dans ton settings.py

Je viens d'essayer. Ça ne marche pas mieux.

Tu as, à priori, un souci dans un de tes fichiers urls.py. La syntaxe normale du pattern d'url est :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
urlpatterns += patterns('',
   url(r'^article/$', news_list, name="news"),
)

tu a du ajouter une url sans passer la bonne syntaxe, exemple de la ligne 'test' qui pose problème :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
urlpatterns += patterns('',
   url(r'^article/$', news_list, name="news"),
   '^test/$',
)

Pour trouver, si ça ne te saute pas aux yeux, mets en commentaires tes url une par une.

J'avais en fait mis en commentaire des UrlsConf dans mon pattern.

Maintenant ça tourne nikel.

Merci

Bonjour à tous.

Je me permets de répondre à ce sujet car je rencontre actuellement le même type de problème avec un site. En effet, le site marche parfaitement bien mais impossible d'accéder à l'admin.
Je précise que je n'y connais rien en Python, ce n'est pas moi qui ai conçu le site mais s'il suffit de corriger quelques lignes, je préfère passer par ici dans un premier temps.
J'ajoute que j'ai essayé les solutions proposées dans ce sujet mais ça n'a pas aidé.
J'ai constaté que les .pyc ont été mis à jour il y a moins d'une semaine. Cela pourrait-il venir de là?

Pour plus d'informations, voici le message d'erreur. Par sécurité, j'ai masqué certains points même si ça reste insuffisant.
