    <p>Using Nodejs Passport, I was testing out what happens when an error condition occurs using the following code:</p> <pre><code>passport.use(new LocalStrategy( function(username, password, done) { // asynchronous verification, for effect... process.nextTick(function () { findByUsername(username, function(err, user) { console.log('in auth function'); return done('errortest'); if (err) { return done(err); } if (!user) { return done(null, false, { message: 'Unknown user ' + username }); } if (user.password != password) { return done(null, false, { message: 'Invalid password' }); } return done(null, user); }) }); } )); app.get('/logintest', function(req, res, next) { console.log('before authenticate'); passport.authenticate('local', function(err, user, info) { console.log('authenticate callback'); if (err) { return res.send({'status':'err','message':err.message}); } if (!user) { return res.send({'status':'fail','message':info.message}); } req.logIn(user, function(err) { if (err) { return res.send({'status':'err','message':err.message}); } return res.send({'status':'ok'}); }); })(req, res, next); }); </code></pre> <p>Using the route /logintest?username=bob&amp;password=s I expected to see in the console, "before authenticate" then "in auth function" then "authenticate callback" but it only shows the first two followed by "errortest", and "errortest" is displayed in the browser.</p> <p>I also tried <code>return done({'message':'test'});</code> and "[object Object]" was displayed in the console and in the browser.</p> <p>Is this not working properly or am I missing something?</p> <p>EDIT: As per Jared Hanson's response, adding this error handler function as the third argument to app.get() allows me to catch the error and return the appropriate json:</p> <pre><code>... })(req, res, next); }, function(err, req, res, next) { // failure in login test route return res.send({'status':'err','message':err.message}); }); </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
