record.get() function

record.get() returns a value from a record by key name or a default value if the key doesn’t exist in the record.

This is an interim solution for the exists operator’s limited use with records outside of a stream of tables. For more information, see influxdata/flux#4073.

Function type signature

(default: A, key: string, r: B) => A where B: Record

Parameters

r

key

default

(Required) Default value to return if the specified key does not exist in the record.

Examples

Dynamically return a value from a record

import "experimental/record"

key = "foo"
exampleRecord = {foo: 1.0, bar: "hello"}

record.get(r: exampleRecord, key: key, default: "")// Returns 1.0
