Login error OERP v8.0

[Adrian]

I was trying to pass mi code from v6.1 to v8.0 and when i'm trying to connect to my OERP server login doesn't work.
oerp = oerplib.OERP(server=OERP_CONF['ip'],
                        database=OERP_CONF['dbname'],
                        protocol=OERP_CONF['protocol'],
                        port=OERP_CONF['port'])

The oerp object is succesfully returned and i checked using for example oerp.db.list() and it works, but when i do
oerp.login(user=OERP_CONF['username'], passwd=OERP_CONF['password']) not working as before when server was in v6.1

try:
        oerp = oerplib.OERP(server=OERP_CONF['ip'],
                        database=OERP_CONF['dbname'],
                        protocol=OERP_CONF['protocol'],
                        port=OERP_CONF['port'])
        user = oerp.login(user=OERP_CONF['username'], passwd=OERP_CONF['password'])
        return oerp
    except:
        return False

Always return False when i call this function for make the connect and i have another error from xmlrpclib that i didn't have before.

Hi,

This is due to a bug in Odoo, some fields on the 'res.users' and 'res.partner' models return None instead of False.
I reported this bug and made a Pull Request to Odoo : https://github.com/odoo/odoo/pull/1284
Not merged yet, we have to wait (or patch Odoo ourself).

Another solution is to make a raw login:

>>> oerp = oerplib.OERP(...)
>>> oerp._uid = oerp.common.login('DB', 'LOGIN', 'PASSWD')
>>> oerp._password = 'PASSWD'
>>> oerp._context = oerp.execute('res.users', 'context_get')
>>> # Use 'oerp' as before

But you can expect the bug you mention as soon as you read a 'res.users' or 'res.partner' record (maybe others?), so I don't know if it suits your needs...

Ok, thanks for the help.
