Hello,
I have a facebook app hosted on heroku working with the lastest stable Web2py. Initially everything works perfect (in local and in production server), but sometimes, when restarting (in case of local on local modifications; and in case of production, either when heroku restarts the server, or on git push heroku master command), sometimes it breaks giving the error: <type 'exceptions.SyntaxError'> No fields to update Traces here: http://pastebin.com/y8bseuAN When this happens, the only way I have found to make it work again, is to actually reset the db (in local, erasing everything and letting web2py remake it all). This, of course, is not too nice. Details on the system, configurations, etc: Facebook application is taken from example https://code.google.com/r/michelecomitini-facebookaccess/ helloFacebook app facebook.py is updated to the latest version of the https://github.com/pythonforfacebook db is configured with: ------------------------------------------------------------ from gluon.contrib.heroku import get_db db = get_db() ------------------------------------------------------------ virtualenv is configured, requirements.txt file has the following ------------------------------------------------------------ argparse==1.2.1 distribute==0.6.24 gunicorn==0.17.2 psycopg2==2.4.6 requests==1.1.0 wsgiref==0.1.2 ------------------------------------------------------------ I have tried with gunicorn and with rocket servers, configuration Procfiles containing ------------------------------------------------------------ either: web: python anyserver.py -s gunicorn -i 0.0.0.0 -p $PORT or: web: python web2py.py -a mypasswd -i 0.0.0.0 -p $PORT ------------------------------------------------------------ Questions: Why is the system trying to update the DB when doing the login with OAuth? Why it should break when an update is empty, instead of ignoring the error and saying that nothing was done instead? Have you got any clues on how to start solving the issue? I sincerely have no clue about what lead to follow. I am tented to modify the dal.py file and tell it to ignore the error Another thing that I need to state: When first tried to login, the redirect address generated by OAuth was wrong, it gave my local personal IP address, instead of the one in the server (I don't know why), I managed to solve it modifying: gluon/contrib/login_methods/oauth20_account.py ------------------------------------------------------------------------------ 105 r = current.request 106 #http_host = r.env.http_x_forwarded_for #THIS was making a problem getting my laptop address instead of my server address ... WHY??? 107 http_host = r.env.http_host ------------------------------------------------------------------------------ Reading in the book (chapter The Core) and in the ref. I do not get why we should use env.http_x_forwarded_for instead of env.http_host , Don't we want the server address to be the redirection address? Why would we even want an address that is the client AND can be spoofed? -- --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
