node.js - cycle for in template and "Cannot read property 'length' of undefined" error when compiling with jade -
so search function route /users/search:
// peopleroutes.js:25:16 exports.search = function (req, res) { var term = req.query.term; user.find({$or: [ {username: {$in: [term]}}, {bio: {$in: [term]}}, {location: {$in: [term]}} ]}, function (err, users) { var fn = jade.compilefile('path/to/template.jade'), {}); var html = fn(users); res.setheader("content-type", 'text/html'); res.send(html); res.end(); }).sort({username: 'asc'}); }; this template want retrieve:
ul.list-group(id='main-list') user in users li.list-group-item div.col-md-3.no-padd-l img(src= user.gravatarurl, alt='avatar') div= user.location div.col-md-9.no-padd-r div.strong= user.username div= user.bio i continue receive following error message:
c:\...\node_modules\jade\lib\runtime.js:240 throw err; ^ typeerror: c:\.../path/to/template.jade:2 1| ul.list-group(id='main-list') > 2| - user in users 3| li.list-group-item 4| div.col-md-3.no-padd-l 5| img(src= user.gravatarurl, alt='avatar') cannot read property 'length' of undefined @ eval (eval @ <anonymous> (c:\...\node_modules\jade\lib\index.js:218:8), <anonymous>:17:31) @ eval (eval @ <anonymous> (c:\...\node_modules\jade\lib\index.js:218:8), <anonymous>:114:4) @ eval (eval @ <anonymous> (c:\...\node_modules\jade\lib\index.js:218:8), <anonymous>:120:22) @ res (c:\...\node_modules\jade\lib\index.js:219:38) @ query.<anonymous> (c:\...\people\peopleroutes.js:25:16) @ c:\...\mongoose\node_modules\kareem\index.js:177:19 @ c:\...\node_modules\mongoose\node_modules\kareem\index.js:109:16 @ process._tickcallback (node.js:355:11) i read there solution rid of "cannot read property 'length' of undefined" error message adding blank line @ end of .jade template doesn't work me. idea on can cause error? user.find query seems return correct values...
i needed use:
var html = fn(users: users); instead of
var html = fn(users);
