map
只需为每个匹配发出两个值,如下所示:
function (doc) {
if (!doc.home || !doc.away) return;
emit([doc._id, "home"], { _id: doc.home });
emit([doc._id, "away"], { _id: doc.away });
}
在查询视图以获取匹配 IDMATCHID
后:
curl 'http://localhost:5984/yourdb/_design/yourpp/_view/yourview?startkey=\["MATCHID"\]&endkey=\["MATCHID",\{\}\]&include_docs=true'
您应该能够在doc
结果列表 ( row
) 中的字段中获取两个团队的文档,可能如下所示:
{"total_rows":2,"offset":0,"rows":[
{"id":"MATCHID","key":["MATCHID","home"],"value":{"_id":"first_team_id"},"doc":{...full doc of the first team...}},
{"id":"MATCHID","key":["MATCHID","away"],"value":{"_id":"second_team_id"},"doc":{...full doc of the second team...}}
