Hello everybody,
I've tried for the last 4 hours to have my web.py application working
with sessions in apache+mod_wsgi, but could not make it.
I've looked in docs, tutorials, searched on google, but could not find
anything...
I'm using web.py 0.3, with python 2.5 and mod_wsgi 2.3
I'm creating a simple document management interface for an association
I'm member of, and I need to use sessions for login states.
Using the web.py integrated server, I've got everything working, with
both a datastore file or db based (the db was sqlite, if it counts).
Now, I've switched to apache as the web server, and nothing works
anymore.
First, my code:
class config:
def __init__(self):
self.curPath = os.path.dirname(__file__)
self.basePath=os.path.join(self.curPath,'..')
self.storePath = os.path.join(self.basePath, 'files')
self.tplPath=os.path.join(self.basePath,'tpl/')
self.sessPath=os.path.join(self.basePath,'sess/')
self.dbPath=os.path.join(self.basePath,'sqlite')
self.dbFile='arcenciel.sqlite3'
self.finalDb=os.path.join(self.dbPath, self.dbFile)
self.debugMode=False
self.frmHome = form.Form(
form.Password('pwd', description='Veuillez donner votre nouveau
mot de passe'),
form.Password('pwd2', description='Veullez retaper votre nouveau
mot de passe'),
form.Button("submit", type="submit", description="Changer de mot
de passe"),
)
self.frmLogin = form.Form(
form.Textbox('username', description="Utilisateur"),
form.Password('pwd', description='Mot de passe'),
form.Button("submit", type="submit",
description="S'authentifier"),
)
self.frmNewFolder=form.Form(
form.Textbox('folderName', description='Donnez le nom du dossier
à créer'),
form.Button("submit", type="submit", description="Créer le
dossier"),
)
self.frmUp=form.Form(
form.File('newFile', description='Fichier à transmettre' ),
form.Button("submit", type="submit", description="Créer le
dossier"),
)
cfg=config()
web.config.debug = cfg.debugMode
app = web.application(urls, globals())
db=web.database(dbn='sqlite', db=cfg.finalDb)
sessVals={'logged': False,
'msg':'',
'user':'',
'uid':False,
}
store = web.session.DBStore(db, 'sessions')
#store = web.session.DiskStore(cfg.curPath+'/sess')
session = web.session.Session(app, store, initializer=sessVals)
The path have all been checked, and they are correct, with permissions
relaxed enough for apache to open/read the files.
the cfg.finalDb resolves to "/var/www/arc_en_ciel/htdocs/../sqlite/
arcenciel.sqlite3", which is an sqlite3 database I created using the
sqlite cli tools.
cfg.debugMode is False, just as a security.
When I enter my first page, I've declared
web.debug(session)
to see the session content.
>From an web.py server, the result is:
<Storage {'msg': u'Erreur de connection.', 'ip': u'127.0.0.1',
'logged': False, 'session_id':
'3f63b62e016a10b8db33a7ef98bc35b712fd0f40'}>
>From apache, the result is
<Storage {}>, referer: http://aec.dev/base.py/
Of course, the same file is used each time.
Has anyone ever faced this situation ?
I'm just "that" close to throw web.py away and redo this with django,
but I love web.py simplicity sooooo much more that it would really
hurt.
