    MongoDB $push Operator - GeeksforGeeks

  5. 123

    The $push operator in MongoDB is used to append a specified value to an array within a document. It can be used with various modifiers for more complex operations1.

    Example: Append a Value to an Array

    db.students.updateOne(
    { _id: 1 },
    { $push: { scores: 89 } }
    )
    // Output: { _id: 1, scores: [44, 78, 38, 80, 89] }

    Using Modifiers with $push

    $each Modifier

    The $each modifier allows you to append multiple values to an array field2.

    db.students.updateOne(
    { name: "joe" },
    { $push: { scores: { $each: [90, 92, 85] } } }
    )

    $sort Modifier

    The $sort modifier sorts the elements of the array. It requires the use of the $each modifier1.

    db.students.updateOne(
    { _id: 5 },
    {
    $push: {
    quizzes: {
    $each: [{ wk: 5, score: 8 }, { wk: 6, score: 7 }, { wk: 7, score: 6 }],
    $sort: { score: -1 },
    $slice: 3
    }
    }
    }
    )

    $slice Modifier

    The $slice modifier limits the number of array elements. It also requires the use of the $each modifier2.

    db.students.updateOne(
    { name: "Rohit" },
    {
    $push: {
    language: {
    $each: ["C", "Go"],
    $sort: 1,
    $slice: 4

    How do I use $push in MongoDB?
    In MongoDB, you can use $push for updates with the following format: { $push: { < field >: < value >, ... } } To specify a field in an embedded document or an array, use dot notation. For example, if you have an array field named 'items' and you want to add a new item, you would use: { $push: { items: { name: 'newItem', value: 'newValue' } } }. In MongoDB 4.4 and earlier, update operators process document fields in lexicographic order.
