Limitation of using id as idProperty and fieldname

[tomalex0]

If we have table field name as "id" which is a primary key, we will have to mention a dummy name(not a field in table) as idProperty of model and clientIdProperty as "id". The issue is that default idProperty of model is "id" which will always have value like this "ext-record-x". If mentioned config options are not specified in model, id value in table will be like ext-record-1,2,3. But we expect it as integer.

Example

Ext.define("Contacts", {
extend: "Ext.data.Model",

        config : {
            idProperty : 'uniqueid', // if we have field with name as id, conflicts happens with default idProperty(id) which always have value as ext-record-x
            clientIdProperty : 'id',
            fields: [{
                name: 'firstName',
                type: 'string'
            }, {
                name: 'lastName',
                type: 'string'
            },{
                name: 'id',
                type: 'int',
                fieldOption: 'PRIMARY KEY'
            }, {
                name: 'modifyDate',
                type: 'string'

            }, {
                name: 'modifyDateParsed',
                type: 'string',
                mapping: 'modifyDate', // not working
                isTableField: false,//newly implemented to distinguish field
                convert: function(value, rec) {

                    var dt  =  Ext.Date.parseDate(rec.get('modifyDate'), "Y-m-d H:i:s")
                    newval  =  Ext.Date.format(dt,'M j, Y, g:i a')
                    return newval;
                }
            }],
            proxy: {
            type: 'sqlitestorage',
            dbConfig: {
                tablename: 'contacts_tables',
                dbConn: Ext.DbConnection.dbConn
            },
            reader: {
                type: 'array'
            }
        }   
        },
        writer: {
            type: 'array'
        }
    });

look for setId this actually adds idProperty("id") to model even if we are not specifying id as field option.

You can use identifier config in the model for set the way sencha generate the ids of the store

....
config: {
identifier: {
type: 'sequential',
prefix: ''
},
.....
}
