Base Writer class used by most subclasses of Ext.data.proxy.Server. This class is -responsible for taking a set of Ext.data.Operation objects and a Ext.data.Request -object and modifying that request based on the Operations.
- - - - -For example a Ext.data.writer.Json would format the Operations and their Ext.data.Model -instances based on the config options passed to the JsonWriter's constructor.
- - - - -Writers are not needed for any kind of local storage - whether via a -Web Storage proxy (see localStorage -and sessionStorage) or just in memory via a -MemoryProxy.
- -This property is used to read the key for each value that will be sent to the server. -For example:
- -Ext.define('Person', {
- extend: 'Ext.data.Model',
- fields: [{
- name: 'first',
- mapping: 'firstName'
- }, {
- name: 'last',
- mapping: 'lastName'
- }, {
- name: 'age'
- }]
-});
-new Ext.data.writer.Writer({
- writeAllFields: true,
- nameProperty: 'mapping'
-});
-
-// This will be sent to the server
-{
- firstName: 'first name value',
- lastName: 'last name value',
- age: 1
-}
-
-Defaults to name. If the value is not present, the field name will always be used.
-True to write all fields from the record to the server. If set to false it -will only send the fields that were modified. Defaults to true. Note that any fields that have -Ext.data.Field.persist set to false will still be ignored.
-Formats the data for each record before sending it to the server. This -method should be overridden to format the data in a way that differs from the default.
-The record that we are writing to the server.
-An object literal of name/value keys to be written to the server. -By default this method returns the data property on the record.
