    <p>I'm trying to use the express middleware for sessions (I'm not understanding but I feel that I am very close).</p> <p>the reason I have ended up asking is that the express docs (<a href="http://expressjs.com/api.html#middleware" rel="nofollow">http://expressjs.com/api.html#middleware</a>) are calling it express.cookieSession where as everyone else (mostly on here) Ive seen discussing it have been calling it express.session. I'm really not sure now, I just have a big lump of possibly useful code ??? but every example I see is different ... how does it work?</p> <pre><code>var express = require('express') , http = require('http'); , app = express(); store = new express.session.MemoryStore; app.use(express.cookieParser()); //app.use(express.cookieSession()); app.use(express.session({secret:'whateverman',key:'express.sid',store:store})); app.use(app.router); app.all('/*',function(req,res,next){res.header("Access-Control-Allow-Origin","*");res.header("Access-Control-Allow-Headers","X-Requested-With");next();}); var server = http.createServer(app); server.listen(8000); var io = require('socket.io').listen(server); io.sockets.on('connection',function(socket){ socket.on('reglogin',function(_){_.session.e='some@email.com';}); }); </code></pre> <p>socket.on('reglogin' produces:</p> <p>TypeError: Cannot set property 'e' of undefined</p> <p>//-------------------------------update on question</p> <p>if express is dependant on connect but express can access connects middleware as if it were its own, eg:</p> <pre><code>app.use(express.cookieSession()); //app is express app.use(connect.cookieSession()); //does exactly the same </code></pre> <p>then surely the same logic would apply to socket.io which is dependant on express:</p> <pre><code>io.use(connect.CookieSession()); //io is socket.io </code></pre> <p>Am I wrong here? does Socket.io have the same .use method? update:(answer is no to io.use)</p> <p>io.interoperate(app.use(express.cookieSession())); LOL</p> <p>----------------------------UPDATE--------------------------------- I've followed the following npm modules guide lines in a despirate attemp to get sessions working and filed each and every time on handshake with no cookie:</p> <p>express.io session.socket.io session.io + sessionstore</p> <p>currently using the latter with console log:</p> <pre><code>warn - handshake error Could not find cookie with key: connect.sid </code></pre>

    1. COIn Express 2, it's `session`; in Express 3, `cookieSession`. That explains the disconnect between what you see on the website (`cookieSession`) and everywhere else (`session`); everywhere else it's outdated.

    2. COwell express is dependent on connect. in connect/lib/middleware i see both session.js and cookieSession.js i'm not seeing the light...

    3. COI think it's because i'm using the req from io not app, io is only listening to app (app is express), but that is only a theory

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
