Repertoire Templates

Je vous donne l erreur et apres ce que j ai fait de mon cote pour debugger le code mais.
Comme je suis un peu nouveau dans mais pas Python.
Voila ce qui s affiche sur mon navigateur.

Traceback (most recent call last):

  File "C:\Python27\lib\site-packages\django\core\servers\basehttp.py", line 283, in run

    raise TemplateDoesNotExist(name)

TemplateDoesNotExist: 500.html

J ai definit cette fonction pour avoir des relatifs tout au debut du fichier settings.py

import os
def rel(*x):
    return os.path.join(os.path.abspath(os.path.dirname(__file__)) ,*x).replace('\\','/')

Et voici mon fichier settings.py

            'propagate': True,
        },
    }
}

Et comme la page 500.html n existe pas
j ai cree une page 500.html contenant

<html><head><body>
Type: {{ type }} <br />
Value: {{ value }} <br />
Traceback: {{ traceback }} <br />
</body></head></html>

dans mon fichier views.py j ai une fonction qui s appelle this_server_error.

def this_server_error(request, template_name='500.html'):
   """
      500 error handler.

       Templates: `500.html`
      Context: sys.exc_info() results
    """
    t = loader.get_template(template_name) # You need to create a 500.html template.
    ltype,lvalue,ltraceback = sys.exc_info()
    sys.exc_clear() #for fun, and to point out I only -think- this hasn't happened at 
                    #this point in the process already
    return HttpResponseServerError(t.render(Context({'type':ltype,'value':lvalue,'traceback':ltraceback})))

que j appelle dans le urls.py du projet de la maniere suivante

handler500 = 'Utilisateurs.views.this_server_error'

Mais malgres tout cela je tombe tjrs sur la meme erreur au debut mon post quelque soit l url que je tape. et le serveur demarre bien

Re : Repertoire Templates

Bonjour,

Afin d'utiliser un handler500, tu dois mettre DEBUG=False:

"If DEBUG is set to True (in your settings module), then your 500 view will never be used, and the traceback will be displayed instead, with some debug information."

Je ne sais pas pourquoi il ne trouve pas le 500.html.
