我有以下JSON结构:
{
orderId : '00410',
name : 'Zuiger',
productionQuantity : '4',
materials : [
{
materialId : 'ALU.BALK.10X70',
description : 'Aluminium balk 10 x 70',
quantityPP : '70mm',
totalQuantity : '0.4'
},
{
materialId : 'ALU.BALK.10X70',
description : 'Aluminium balk 10 x 70',
quantityPP : '70mm',
totalQuantity : '0.4'
}],
operations : [
{
operationId : 'ZAGEN',
lineNr : '10',
description : 'Zagen groot',
started : false
},
{
operationId : 'FR003',
lineNr : '20',
description : 'Frezen Heidenhein',
started : true
}]
}
所以我有一个订单,其中包含材料清单和/或操作清单。此JSON当前位于使用Data标记的Store文件中,并且是自动加载的。这是出于测试目的。
用于此的模型是Order,它包含2个与材料和操作有关的多个关联:
Ext.define('wp-touch.model.Order', {
extend: 'Ext.data.Model',
requires: [
'wp-touch.model.Material',
'wp-touch.model.Operation'
],
config: {
idProperty: 'Id',
fields: [
{ name: 'orderId', type: 'string'},
{ name: 'name', type: 'string'},
{ name: 'productionQuantity', type: 'string'},
],
associations: [
{
type: 'hasMany',
associationKey: 'materials',
model: 'wp-touch.model.Material',
name: 'material',
primairyKey: 'materialId',
foreignKey: 'orderId'
},
{
type: 'hasMany',
associationKey: 'operations',
model: 'wp-touch.model.Operation',
name: 'operation',
primairyKey: 'operationId',
foreignKey: 'orderId'
}
],
}});
当商店加载时,它只加载第一个hasMany。当我在JSON消息中清空材料数组时,它在操作中加载就好了。所以它似乎只加载了一个hasMany关联。有什么方法可以解决这个问题吗?
以下是材料和操作模型;
Ext.define('wp-touch.model.Material', {
extend: 'Ext.data.Model',
config: {
idProperty: 'Id',
fields: [
{ name: 'materialId', type: 'string'},
{ name: 'description', type: 'string'},
{ name: 'quantityPP', type: 'string'},
{ name: 'totalQuantity',type: 'string'},
{ name: 'orderId', type: 'string'}
],
belongsTo: [
{
model: 'wp-touch.model.Order',
name: 'order',
primairyKey: 'materialId',
foreignKey: 'orderId'
}
]
}});
Ext.define('wp-touch.model.Operation', {
extend: 'Ext.data.Model',
config: {
idProperty: 'Id',
fields: [
{ name: 'operationId', type: 'string'},
{ name: 'lineNr', type: 'int'},
{ name: 'description', type: 'string'},
{ name: 'started', type: 'boolean'},
{ name: 'orderId', type: 'string'}
],
belongsTo: [
{
model: 'wp-touch.model.Order',
name: 'order',
primairyKey: 'operationId',
foreignKey: 'orderId'
}
]
}});
