私は、mongoDBコレクション内のドキュメントをフィルタリングし、金曜日、土曜日、または日曜日に一致する日付を持つすべての結果を返す関数を持っています。これは、期待どおりに動作します。しかし、今週末に来るかどうかを判断するためにこれらの結果を一致させる必要がありますが、私のwhileループは3を返すべきときに1つの結果しか返しません。何がうまくいかないのですか?ループ中に何が問題になっていますか?
//FIND ALL ENTRIES THAT FALL ON A WEEKEND
function weekendPlans(callback) {
Entry.aggregate(
[
{ "$redact": {
"$cond": {
"if": {
"$or": [
{ "$eq": [ { "$dayOfWeek": "$selectedDate" }, 1 ] },
{ "$eq": [ { "$dayOfWeek": "$selectedDate" }, 6 ] },
{ "$eq": [ { "$dayOfWeek": "$selectedDate" }, 7 ] }
]
},
"then": "$$KEEP",
"else": "$$PRUNE"
}
}}
],
// GET THE RESULTS AND RETURN IF selectedDate MATCHES THIS WEEKEND
function(err,results) {
var i = results.length;
var theWeekend;
console.log(results)
// EVERYTHING WORKS UNTIL HERE
while(i--) {
if(results[i].selectedDate === friday || saturday || sunday) {
theWeekend = results[i];
//console.log(theWeekend);
break;
}
}
callback(err, theWeekend)
}
)};
期待される結果:
