GeoFirestore-是否可以在GeoQuery中组合near()和where()方法? [英] GeoFirestore - Is it possible to combine the methods near() and where() in a GeoQuery?

问题描述

 //查询让查询= geoCollection.where(状态"，"=="，活动").near({中心:new firebase.firestore.GeoPoint(纬度，经度，半径:1000}));//订阅，将作业添加到存储中并侦听更改query.onSnapshot((res)=> res.docs& Array.from(res.docs.map((doc)=> console.log(doc.data()))))); 

当我执行上述操作时，它无法正常工作.但是如果我这样做，它会起作用:

 让query = geoCollection.where("status"，"=="，"active") 

或

 让查询= geoCollection.near({中心:new firebase.firestore.GeoPoint(纬度，经度，半径:1000})); 

但不能在一起！这就是我想要的.

这是文档的链接.它不是很详细，但是我尽力调查了文件，到目前为止还没有运气.

解决方案

终于找到了解决方案.要求您在Cloud Firestore控制台中创建索引.

1. 在我的情况下，您在第一个字段中输入的收藏名称是工作"
2. 将"where"放置在字段(升序)中要与之进行比较的媒体资源
3. 最后，键入 g.geohash (升序)
4. 单击保存"，然后等待大约5到10分钟.

 // Queries
 let query = geoCollection
    .where("status", "==", "active")
    .near({ center: new firebase.firestore.GeoPoint(latitude, longitude), radius: 1000 });

 // Subscribe, add jobs into store and listen for changes
 query.onSnapshot((res) => res.docs && Array.from(res.docs.map((doc) => console.log(doc.data()))));

When I perform the above it doesn't work properly. but if I do this instead it works:

 let query = geoCollection.where("status", "==", "active")

or

let query = geoCollection.near({ center: new firebase.firestore.GeoPoint(latitude, longitude), radius: 1000 });

But not together! Which is what I want.

Here is the link for the Documentation. It's not very detailed, but I tried my best to look into the files and no luck so far. https://firebaseopensource.com/projects/geofirestore/geofirestore-js/

Here is a picture of the structure:

解决方案

Finally found a solution. It is required that you create an Index in the Cloud Firestore console.

1. Put your collection name in the first field in my case was "jobs"
2. Put the "where" property that you are comparing to in the field (Ascending)
3. Lastly, type g.geohash (Ascending)
4. Click Save, and wait around 5 and 10 minutes.
