Question

I try to insert a new record into a store to avoid Ext.data.Store.load(); which will load all data again from a defined proxy.

Is it possible to insert a new Ext.data.Record without defining columns and datatypes?

I want something like this:

var myStore = this.grid.getStore();

myStore.insert({
  firstColumn: 'myValueForTheFirstColumn',
  secondColumn: 'myValueForTheSecondColumn'
});

Many thanks in advance!

Thanks Lolo,

this fixed my problem 😉

Here’s the code how I solved the issue:

var cm = this.grid.getColumnModel(); // getting the column model
var cc = cm.getColumnCount(); // getting number of counts (before add)
var lastStoreRecordIndex = this.grid.getStore().getCount() - 1; // getting the 
                                                                // last record
                                                                // (before add)
// the approximated ID which could be in the database
// (this is too optimistic in critical applications)
var approxId = this.grid.getStore().getAt(lastStoreRecordIndex).get('id') + 1;

// building a new record based on the columns of the current column model
var ch = '', data = new Object();
for (var i = 0; i < cc; ++i) {
  ch = cm.getColumnHeader(i);

  data[ch] = '';
}

this.grid.getStore().add([new Ext.data.Record(data)]); // add and be happy! ;-)
