Bonjour a tous

je suis sous Ubuntu 14.04
je suis en train d'installer Django et j'ai lu dans la doc qu'il fallait utiliser le module "mysqlclient"

quand je lance la commande:

root@linux-pc:/home/siteweb# python3.4 manage.py migrate

voila ce que j'obtiens:

Traceback (most recent call last):

j'ai telecharge le module "mysclient1.3.4-cp34-none-win_amd64.whl

comment installer ce module?
comment faire marcher la commande?

root@linux-pc:/home/siteweb# python3.4 manage.py migrate

Merci pour votre aide

[wiztricks]

Salut,

pip install mysqlclient devrait dans un premier temps suffire.
Ceci dit, il y a certainement des pré-requis comme installer MySQL.

Notez que pour débuter avec Django, le SGDB SQLite3 qui est inclus avec Python suffit largement.

je ne peux visiblement pas me connecter a ma base mysql
pourtant mysqld tourne et je me suis connecte a phpmyadmin

peut etre faut il indiquer quelque part le nom d'une base de donnees et son login et mot de passe Non?

Merci
T.

[trazomtg]

j'ai trouve dans le fichier

local/lib/python3.4/dist-packages/django/db/backends/__init__.py


def __init__(self, settings_dict, alias=DEFAULT_DB_ALIAS,
allow_thread_sharing=False):
# `settings_dict` should be a dictionary containing keys such as
# NAME, USER, etc. It's called `settings_dict` instead of `settings`
# to disambiguate it from Django settings modules.
self.connection = None
self.queries = []
self.settings_dict = settings_dict
self.alias = alias
self.use_debug_cursor = False



est ce que c'est la que l'on definit les parametres de connexion a la base de donnees?

je ne vois nulle part ou on mentionne ces parametres.

Merci

[trazomtg]

je suis un peu perdu!

j'ai telecharge le fichier mysqlclient 1.3.4
C'est un fichier .atr et je ne sais pas quoi en faire!!!!!

comment l'installer?

ma base de donnees est accessible

quand je lance la commande migrate sans specifier de base de donnees j'obtiens :

Hello,

Peut-être que la première étape avant de s'attaquer à django sous ubuntu serait d'apprendre à utiliser ubuntu.

Pour installer un logiciel, on ne va jamais télécharger n'importe quoi n'importe où !

Enfin pour débuter, on cherche pas de la doc n'importe où non plus. On commence par le site officiel : https://docs.djangoproject.com/fr/1.7/
