Access a Value

Overview

You can access an Atlas App Services Value from a rule expression or an Atlas Function.

Usage

Reference a Value in a JSON Expression

You can access a Value's stored data from a JSON expression using the %%values expansion.

"%%values.<Value Name>"

Example

The following JSON expression evaluates to true when the active user's id is included in the plain text array Value adminUsers:

{ "%%user.id": { "$in": "%%values.adminUsers" } }

Reference a Value in a Function

You can access a Value's stored data from a Function using the context.values module.

context.values.get("<Value Name>")

Example

The following Function returns true when the active user's id is included in the plain text array Value adminUsers:

exports = function() {
    const adminUsers = context.values.get("adminUsers");
    const isAdminUser = adminUsers.indexOf(context.user.id) > 0;
    return isAdminUser;
}
