$CloudObjectNameFormat

is the default setting used for the CloudObjectNameFormat option when constructing a CloudObject.

Basic Examples  (1)

By default, newly created named cloud objects use $UserURLBase to format the username in their URLs:

Wolfram Language code: $CloudObjectNameFormat

Its actual value can be obtained with $UserURLBase:

Wolfram Language code: $UserURLBase

Change the name format to the user UUID:

Wolfram Language code: $CloudObjectNameFormat = "CloudUserUUID"

A named object uses the user UUID in the URL:

Wolfram Language code: CloudObject["nameFormatExample.wl"]

Possible Issues  (1)

$CloudObjectNameFormat with a value of "UUID" cannot be applied if the destination is a named CloudObject that does not exist.

First, create a cloud object:

Wolfram Language code: co = CloudPut[123, CloudObject["expression.wl"]]

Check that the cloud object exists in the cloud:

Wolfram Language code: FileExistsQ[co]

Because it exists in the cloud, it has a known "UUID" associated with it:

Wolfram Language code: CloudObject[co, CloudObjectNameFormat -> "UUID"]

Here, the content of the cloud object is replaced with 456 and the URL of the cloud object is given in "UUID" form:

Wolfram Language code: Block[{$CloudObjectNameFormat = "UUID"}, CloudPut[456, CloudObject["expression.wl"]]]

Delete the object:

Wolfram Language code: DeleteObject[CloudObject["expression.wl"]]

The named cloud object no longer exists, so the newly created cloud object is not returned in UUID format because the cloud object was created in "UserURLBase" format:

Wolfram Language code: Block[{$CloudObjectNameFormat = "UUID"}, CloudPut[789, CloudObject["expression.wl"]]]

Delete the object:

Wolfram Language code: DeleteObject[CloudObject["expression.wl"]]

Here, the destination is not using the CloudObject constructor, so the cloud object is constructed with a UUID:

Wolfram Language code: Block[{$CloudObjectNameFormat = "UUID"}, CloudPut[789, "expression.wl"]]
