我想將當前日期添加到用戶膳食計劃早餐中，并在條件下找到像香蕉這樣的物件的名稱并將日期添加到已完成的陣列中？
這是貓鼬檔案。每個食物專案都包含一個已完成的陣列，每次發送請求時，它都會在已完成的陣列上添加或洗掉日期。我應該能夠將日期推送到已完成的陣列
{
"_id": {
"$oid": "616f193e9eb4ca14afc47fa8"
},
"date": {
"$date": "2021-10-19T15:52:09.298Z"
},

"daysofweek": []
}
},
{

"completed": [],
"name": "orange juice",
"numbers": 1,
"unit": "100 mililiters",
"recurring": {},
"orac": 10,

},
{
"type": "breakfast",
"name": "banana",
"completed": [],
"numbers": 1,
"unit": "100 grams"
}
]
},
"__v": 0
}
當我發送郵件請求時，它將是食物的名稱和日期。日期顯示以食物的名義添加到完成的陣列中
uj5u.com熱心網友回復：
使用arrayFilter這樣
的例子中，我們要添加到食物的名稱bnana
db.collection.update({},
{
$push: {
"mealplan.breakfast.$[arr].completed": "date" // put date here
}
},
{
arrayFilters: [
{
"arr.name": "banana" // name of food here
}
]
})
