Mongoose delete an item in an array

Question

i am a beginner in mongoose and i am trying to delete an element in array but i am facing troubles to do it

my schema is like this

    name : {
        type: String,
        trim : true
    },
    pictures: {
        type : Array,
        required : false
    },

and in my database it looks like this

{
    "_id" : ObjectId("5eb67e7c74b35b205362b7f4"),
    "title" : "john doe",
    "pictures" : [ 
        "img1.jpg", 
        "img2.png", 
        "img3.jpg", 
        "img4.jpg", 
        "img5.jpg"
    ]
}

how can i delete an item in the array of pictures?

Answer 1

You need $pull operator:

await Model.updateOne({"_id" : ObjectId("5eb67e7c74b35b205362b7f4")}, {$pull: { "pictures": "img1.jpg"}});
