ExtJs - Renderer for remote store combobox in grid editor -


i know has been asked somewhere again , again can't find solid answer standard kind of problem.

as many have done before have editor inside grid combobox uses remote store database. suppose there table in database 50,000 records. combobox loads first 15. when select record between these 15 displays fine. render displayfield instead valuefield, use following function

  rendercombobox : function(value, metadata, record, rowindex, colindex, store, view, isnewrow){             var me      = this,           columns = me.columns,           editor, editorstore, editorindex, displayfield, display, rec;      for(var i=0,j=columns.length;i<j;i++){                 if(columns[i].geteditor){           editor = columns[i].geteditor(record);           if(editor.xtype === 'combobox'){               editorstore   = editor.getstore().load();               editorindex   = editorstore.findexact(editor.valuefield, value);               displayfield = editor.displayfield;           }       }     }           if(editorindex != -1){         rec = editorstore.getat(editorindex);         if(rec && rec.get(displayfield)){             display = rec.get(displayfield);         }                    }           return display;         }

the problem following scenario.

if type ahead, can find record not between these 15 records. example record 42,300. select , moment ok. if click on field on editor in grid (i.e. datefield) renderer function combobox returns undefined tries find record value of record 42,300 not exist in store. debugger says store contains again first 15 records.

is there configuration miss? store needs limitation. can't bring 50,000 records database @ once.

i think example want: http://extjs.eu/ext-examples/#combo-in-grid

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
