声明数组searchFields工作灯JSONStore [英] Declare array into searchFields Worklight JSONStore

问题描述

我有一个JSON对象到我的收藏与JSONStore是这样的：

I have a JSON object to my collection with JSONStore like this:

{
    name : 'name1',
    industry : ['Banking', 'Energy', 'Insurance', 'Media', 'Retail', 'Telco', 'Travel'],
    buyer : ['CMO'],
    link : 'foo.com' 
}

但是，如何可能声明行业领域进入searchFields？为了在数组中搜索模式。

But, how is possible declare the industry field into searchFields?, in order to search a pattern in the array.

干杯

推荐答案

有没有阵列键入搜索字段。你只能在对象的索引值是字符串，布尔，数量和整数。

There's no array type for search fields. You can only index values in objects that are string, boolean, number and integer.

您可以更改：

{ industry : ['Banking', 'Energy'] }

到

{ industry : [{name: 'Banking'}, {name: 'Energy'}] }

，然后使用以下搜索字段： {'industry.name'：'串'} 。这将使你能够做类似 WL.JSONStore.get（'收集'）找到（{'industry.name'：'银行'}，{确切：真}）并取回像这样的一个对象：

and then use the following search field: {'industry.name' : 'string'}. That will enable you to do something like WL.JSONStore.get('collection').find({'industry.name' : 'Banking'}, {exact: true}) and get back an object like this one:

[{_id: ..., json: {name: ..., industry: [..., {name: Banking}, ...], buyer: ..., link: ...}}]

这是在文档中的一般术语的搜索领域部分<一个记录href=\"http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.dev.doc/devref/c_jsonstore_terminology.html\">here.

This is documented under the search field section of general terminology in the documentation here.

这将意味着写code这样的改变被添加到集合中的数据：

That would mean writing code like this to change the data being added to the collection:

var output = [];
['Banking', 'Energy', 'Insurance', 'Media'].forEach(function (element) {
    output.push({name: element});
});
console.log( JSON.stringify(output, null, ' ') ); 

另外，你也可以把它变成一个字符串：

Alternatively, you could also change it into a string:

{industry : ['Banking', 'Energy', 'Insurance', 'Media'].toString() }

和取回是这样的：

{industry : "Banking,Energy,Insurance,Media"}

然后就可以使用搜索栏 {行业：'字符串'} 并做类似 WL.JSONStore.get（'收集'） .find（{产业：'能源'}，{确切：假}）来获得在<$ C $有物体能源某处C>行业字符串值。

Then you can use the search field {industry : 'string'} and do something like WL.JSONStore.get('collection').find({industry: 'Energy'}, {exact: false}) to get objects that have Energy somewhere in the industry value string.
