如何在Falcor中构建多参数搜索 [英] How to structure a multi-parameter search in Falcor

问题描述

为Falcor查询构造搜索路径的最佳做法是什么?

What are the best practices in constructing search paths for Falcor queries?

在人员配备域中，有一个示例，其中人员配备协调员正在尝试为项目需求配备人员:

Here an example from a Staffing domain where a staffing coordinator is trying to staff people for project needs:

• 需求具有startDate和endDate-两者都是需求的简单字符串属性
• 需要一个project，因此它引用了一个项目
• 需要一个skill，因此它具有对技能的引用

• A need has startDate and an endDate - both are simple string properties of the need
• A need is for a project, hence it has a reference to a project
• A need is for a skill, so it has a reference to a skill

以下是NeedMap中的需求:

Here's what a need looks like in a needMap:

needMap: {
    101: {
        startDate: '2016-07-04T04:00:00.000Z',
        endDate: '2016-10-22T03:59:59.999Z',
        project: $ref('projectMap[87]'),
        skill: $ref('skillMap[3]')
    },
    ...
}

如何指定符合以下条件的所有需求的搜索:

How do I specify a search for all needs that match the following criteria:

• minStartDate:所需的最短开始日期
• maxStartDate:所需的最大开始日期
• projectId:仅需对此项目进行过滤
• skillId:仅需具备此技能即可过滤

• minStartDate: minimum start date for the need
• maxStartDate: maximum start date for the need
• projectId: filter to needs to only this project
• skillId: filter to needs to only this skill

注意:我不是在寻找进行实际搜索的代码或想法，只是在寻找如何使用Falcor路径概念指定搜索.

Note: I am not looking for the code or ideas to do the actual search, only how to specify the search using Falcor path concepts.

推荐答案

问题#713 和github中的falcor储存库中的#775 可以解决此问题.出现两种可能的解决方案:

The issues #713 and #775 from the falcor repository in github address this. Two possible solutions appear :

• 您可以使用查询字符串，对于您的情况，它将是这样的:model.get(["needs", "search", "minStartDate=2016&maxStartDate=2016&projectId=$ref(projectMap[87])])
• 您可以使用另一个端点进行搜索，然后仅使用falcor来获取有关另一个端点返回的结果的更多信息

我猜另一种选择是使用call而不是get，因为这允许您传递多个参数.您会遇到这样的事情:

I guess another option would be to use a call rather than a get, as this allow you to pass multiple parameters. You would have something like this:

model.call(
    ["model", "search"],
    {
        minStartDate: "2016",
        maxStartDate: "2016",
        projectId: $ref('projectMap[87])
    },
    [],
    []);
