我想我知道该怎么做,但我也有类似的问题。我实际上无法让我的关联给我相关的数据。无论如何,根据我在互联网上搜索的内容,制作一个像这样的自定义编写器,或者只是在默认编写器中 getRecordData: function(record,operation)
这是我的自定义作家
Ext.define('Wakanda.writer', {
extend: 'Ext.data.writer.Json',
// alternateClassName: 'SimplyFundraising.data.WakandaWriter',
alias: 'writer.wakanda',
writeAllFields: false,
getRecordData: function(record,operation) {
debugger;
Ext.apply(record.data,record.getAssociatedData());
debugger;
var isPhantom = record.phantom === true,
writeAll = this.writeAllFields || isPhantom,
nameProperty = this.nameProperty,
fields = record.fields,
data = {},
changes,
name,
field,
key;
if (writeAll) {
// console.log("getRecordData1", this, arguments);
fields.each(function(field){
if (field.persist) {
debugger;
name = field[nameProperty] || field.name;
data[name] = record.get(field.name);
} else {
}
});
} else {
changes = record.getChanges();
debugger;
// console.log("getRecordData2", this, arguments, changes);
for (key in changes) {
if (changes.hasOwnProperty(key)) {
field = fields.get(key);
name = field[nameProperty] || field.name;
data[name] = changes[key];
}
}
if (!isPhantom) {
debugger;
data[record.idProperty] = record.getId();
if(operation.action !== 'destroy'){
data[record.stampProperty] = record.get(record.stampProperty);
}
}
}
return {'__ENTITIES': [data]};
}
});
我认为关键是在 getRecordData 中,我有一个语句 Ext.apply(record.data,record.getAssociatedData()); 如果 record.getAssociatedData 确实返回了您的数据,那么 Ext.apply 语句会将您当前的 record.data 与您的 record.getAssociatedData 合并到 1 个 json 文件中。至少这是我希望发生的事情。在我正确设置关联之前无法测试。
希望这会有所帮助,丹
getRecordData: function(record,operation) {
debugger;
Ext.apply(record.data,record.getAssociatedData());
