mongosh Method

This page documents a mongosh method. This is not the documentation for a language-specific driver, such as Node.js.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

Configures the cursor to display results in a format that is easy to read.将游标配置为以易于阅读的格式显示结果。

The pretty() method has the following prototype form:pretty()方法具有以下原型形式：

db.collection.find(<query>).pretty()

Behavior行为

The pretty() method:pretty()方法：

• Does not change the output format in mongosh.不更改mongosh中的输出格式。
• Changes the output format in the legacy mongo shell.更改传统mongo shell中的输出格式。

Examples实例

Consider the following document:请考虑以下文件：

db.books.insertOne({
    "_id" : ObjectId("54f612b6029b47909a90ce8d"),
    "title" : "A Tale of Two Cities",
    "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...",
    "authorship" : "Charles Dickens"})

By default, db.collection.find() returns data in a dense format:默认情况下，db.collection.find()以密集格式返回数据：

db.books.find()
{ "_id" : ObjectId("54f612b6029b47909a90ce8d"), "title" : "A Tale of Two Cities", "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...", "authorship" : "Charles Dickens" }

By using cursor.pretty() you can set the cursor to return data in a format that is easier to read:通过使用cursor.pretty()，您可以将游标设置为以更易于读取的格式返回数据：

db.books.find().pretty()
{
    "_id" : ObjectId("54f612b6029b47909a90ce8d"),
    "title" : "A Tale of Two Cities",
    "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...",
    "authorship" : "Charles Dickens"
}
