Access a Value¶

Overview¶

You can reference a Realm Value from a JSON expression or a Realm 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:

copy

{ "%%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.

copy

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:

copy

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

Summary¶

You can access a Realm Value from a JSON expression or from a Realm Function.
