# Quickbase fields as QBL objects

For all field objects in QBL:

- Restrict access by role properties are visible in QBL in the Field objects, not in the Role objects.
- All limits and validations in the UI apply in QBL too

## Snapshot property

See [Setting Up Snapshots of Lookup Fields](/v1/docs/setting-up-snapshots-of-lookup-fields)

The QBL file shows in the property information that Snapshot is activated in the selected lookup field.

The initialization checkbox is not represented as a property in QBL. It is not a schema configuration. Rather, it is an action this is triggered. Quickbase will not trigger the initialization action every time you execute a [create or update API call](/v1/docs/solution-apis).

## Uniqueness property

The QBL file shows in the property information that a field is required to be unique. However, "check existing entries for duplicated values" checkbox is not represented in QBL. It is not a schema configuration. Rather, it is an action that is triggered. Quickbase will not trigger the initialization action every time you execute a [create or update API call](/v1/docs/solution-apis).

## Fields that are QBL objects

Most field types are supported as QBL objects. Only a few are unsupported. See all supported and unsupported fields by selecting your [version](/v1/docs/qbl-versions) and following the links to the **Field properties** and **Formula field properties** articles.
