I've a question:
How i can find all documents that have a string in an array using mongoose?
For example, my document:
<Model>.findMany(/* code that i need */).exec() // return all documents that have an array called "tags" that includes tag "test"
{
"_id": {
"$oid": "61b129b7dd0906ad4a2efb74"
},
"id": "843104500713127946",
"description": "Server di prova",
"tags": [
"developers",
"programming",
"chatting",
"ita"
],
"shortDescription": "Siamo un server nato per chattare e aiutare programmatori su Discord!",
"invite": "https://discord.gg/NdqUqHBxz9",
"__v": 0
}
For example, if I need to get all documents with ita tag, I need to get this document.
If the document doesn't have ita tag in array tag, I don't need it and the code will not return it.
Thanks in advance and sorry for bad english.
Actually you can just request tags to be test since mongoose looks for every tags entry
so this:
await Test.insertMany([{ tags: ["test"] }, { tags: ["Notest"] }])
let res = await Test.find({ "tags": "test" })
console.log(res)
}
returns that:
[
{
_id: new ObjectId("61b8af02c3effad21a5d7187"),
tags: [ 'test' ],
__v: 0
}
]
2 more neat things to know:
Example for 2nd:
let res = await Test.updateMany({ "tags": "test" }, { $set: { "tags.$": "new" } }, { new: true })
