virtual bool | WriteAllFields [get, set] |
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 false. More... | |
virtual JFunction | GetRecordData [get] |
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. Parameters record : Object The record that we are writing to the server. Returns An object literal of name/value keys to be written to the server. By default this method returns the data property on the record. More... | |

virtual TransformFunction | Transform [get] |
If a transform function is set, it will be invoked just before writeRecords executes. It is passed the unserialized data object and the request object. The transform function returns a data object, which can be a modified version of the original data object, or a completely new data object. The transform can be a function, or an object with a 'fn' key and an optional 'scope' key. Example usage: Ext.create('Ext.data.Store', { model: 'User', proxy: { type: 'ajax', url : 'users.json', writer: { type: 'json', transform: { fn: function(data, request) { /// do some manipulation of the unserialized data object return data; }, scope: this } } } }); More... | |

virtual bool | WriteRecordId [get, set] |
By default, each record's id is always included in the output for non-phantom records since in most cases the id will be required on the server to process the record action. This is helpful since the id will normally not be modified, and so would not be sent to the server unless writeAllFields was explicitly enabled. However, there are cases where it is not desirable for the record id to be passed in the data directly. For example, when using a RESTful API the record id would typically be appended to the url instead. Defaults to: true More... | |

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.

getset |
When specified this property causes the Ext.data.Model.idProperty of newly created records to be sent to the server as this name instead of the value of the idProperty.
For example, by default, the following code:
Ext.define('Person', { idProperty: 'id', /// this is the default value (for clarity)
fields: [ 'name' ] });
var person = new Person({ /// no id provided, so one is generated name: 'Clark Kent' });
Will send this to the server:
{ id: 'Person-1', name: 'Clark Kent' }
This can be an issue if the server expects an integer for the "id" property. You can use Ext.data.Model.identifier to produce identifiers that the server would recognize or use this config to send the client's id in a different property.
Ext.define('Person', { idProperty: 'id', /// this is the default value (for clarity)
proxy: { writer: { clientIdProperty: 'clientId' } },
fields: [ 'name' ] });
Given the above, the server is sent this data now:
{ clientId: 'Person-1', name: 'Clark Kent' }
While this config provides the behavior of Ext.data.Model.clientIdProperty from previous releases, this property is not as useful as a suitable Ext.data.Model.identifier due to id's appearing in foreign-key fields and in Ext.data.Model.manyToMany associations.
See Ext.data.Model.identifier for more on id generation.

This property is used to read the key for each value that will be sent to the server. For example:
Ext.regModel('Person', { 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.
