extjs4 - Extjs Get Id from database and pass it to component -


problem facing is. have form query database , information on cars, unique id of data , pass made component.

 layout : 'fit',  items : [{        xtype: 'cargrid',        autoscroll: true        //here want id passed cone  }]

maybe, did u want show id of row on grid ?

  1. you need on store/model. define 1 'id' field on data store.

model:

fields: [              {name: 'idrow'},              {...} ]
  1. on grid, define 1 column, same name of "store field id" on dataindex:

grid view:

columns: [{         header: "identificator",         dataindex: 'idrow'     },         {...}  ]

edit:

if want overwrite de id:

see link belong: itemid

and in comment: (copy&paste)

example:

var c = new ext.panel.panel({ //     height: 300,     renderto: document.body,     layout: 'auto',     items: [         {             itemid: 'p1',             title: 'panel 1',             height: 150         },         {             itemid: 'p2',             title: 'panel 2',             height: 150         }     ] }) p1 = c.getcomponent('p1'); // not same ext.getcmp() p2 = p1.ownerct.getcomponent('p2'); // reference via sibling

comment:

    ext.apply(c, {         itemid : 'p3'     }

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
