Successful post, but infinite update loop after
Hi, I am having very strange issue with my code.
I have two models Company and Warehouse associated in following way:
Company hasOne Warehouse -> client (extjs) side
Company is associated with Warehouse on primary key join column manner -> hibernate, server
Problem occurs when I try to create new company along with warehouse and this is what I am sending to the server
Code:
{"data":[{"id":0,"name":"d","longName":"d","warehouse_id":0,"warehouse":{"id":0,"name":"d","description":"d","size":100,"createdDate":"2012-12-03T00:00:00","usage":"0.00"}}]}
I am able to receive successful server's answer that both company and warehouse had been insterted into tables.
This is the answer
Code:
- action: "CREATE"
- data: [{longName:d, warehouse:{id:4, name:d, createdDate:0-338-2012, description:d, usage:0, size:100},…}]
- 0: {longName:d, warehouse:{id:4, name:d, createdDate:0-338-2012, description:d, usage:0, size:100},…}
- id: 4
- longName: "d"
- name: "d"
- warehouse: {id:4, name:d, createdDate:0-338-2012, description:d, usage:0, size:100}
- createdDate: "0-338-2012"
- description: "d"
- id: 4
- name: "d"
- size: 100
- usage: 0
- entity: "wms.model.Company"
- handler: "wms.controller.CompanyController"
- message: "CREATE took 108ms and affected 1 rows"
- success: true
- time: 108
- total: 1
As you can see company and warehouse ID are the same which is good. But right after POST, PUT is triggered with following payload
Code:
{"data":[{"id":4,"name":"d","longName":"d","warehouse_id":0}]}
Here warehouse_id is magically gone and I don't have any idea why.
In one word client goes in infinite loop with server by sending PUT request with exact same payload and receiving exact same answers with the difference on action in response's object.
Here is the code for company and warehouse model on the client side
Code:
Ext.define('WMS.model.entity.Company', {
extend : 'WMS.model.abstract.Simple',
requires : [
'WMS.model.entity.Warehouse'
],
fields : [
{ name: 'longName', type: 'string' },
{ name: 'warehouse_id', type: 'int', mapping: 'warehouse.id'}
],
associations: [
{
type : 'hasOne',
name : 'warehouse',
associationName: 'warehouse',
instanceName : 'warehouse',
foreignKey : 'warehouse_id',
model : 'WMS.model.entity.Warehouse',
getterName : 'setWarehouse',
setterName : 'getWarehouse'
}
],
proxy : {
type : 'wms',
url : 'wms/agent/company',
writer: {
type : 'json',
root : 'data',
allowSingle : false,
writeAllFields: false,
getRecordData : function (record, operation) {
var company,
action = operation['action'];
if (action === 'create') {
var company = record.getData(),
warehouse = record['warehouse'];
company['warehouse'] = warehouse.getData();
var warehouseID = company['warehouse_id'];
if (Ext.isDefined(warehouseID) && warehouseID === 0) {
delete company['warehouse_id'];
}
} else {
company = record.getData();
}
return company;
}
}
}
});
Code:
Ext.define('WMS.model.entity.Warehouse', {
extend : 'WMS.model.abstract.DescribedSimple',
fields : [
{ name: 'usage', type: 'float', defaultValue: 0.0, convert: convertUsage},
{ name: 'size', type: 'int', defaultValue: 0},
{ name: 'createdDate', type: 'date', serialize: serializeDate}
],
proxy : {
type: 'wms',
url : 'wms/agent/warehouse'
}
});
