javascript - Getting undefine trying to get the ObjectId of a Collection -


i'm making voting system message board app using backbone. problem here when try objectid of object , set "rel" attribute in tag attribute set "undefined" . 

<% if(models.length>0) {                     _.each(models, function(value, key, list) {%>                     <tr>                         <td><%= value.attributes.username %></td>                         <td><%= value.attributes.message %></td>                         <td>                             <table>                                 <tr>                                     <td><a id="voteup" class="btn btn-default btn-sm" rel="<%= value.attributes.objectid%> "><img width="30" src="img/appbar.thumbs.up.png"/></a></td>                                     <td width="30">                                         +<%= value.attributes.thumbsup %>                                     </td>                                     <td>                                         <a id="votedown" class="btn btn-default btn-sm" rel=" <%= value.attributes.objectid %> "><img width="30" src="img/appbar.thumbs.down.png"/></a>                                     </td>                                     <td width="30">                                         -<%= value.attributes.thumbsdown %>                                     </td>                                 </tr>                             </table>                         </td>                      </tr>                     <%  });

in db on parse objectid show can access username, message, thumbsup, thumbsdown.

here jsfiddle complete home.html , app.js

i think should debug backbone/parse collection layer , first determine type reference dealing with??

attributes or objects @ level of entries in backbone collection

the answer determines how backbone unwrap individual collection entries.

note this thread remembering parse referents can little finicky regarding valueof(objectid).

if getting other field values ok target class , objectid 1 bug, issue.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
