Instance Attribute Details

#user_project ⇒ Object

A boolean value or a project ID string for a requester pays bucket and its files. If this attribute is set to true, transit costs for operations on the bucket will be billed to the current project for this client. (See Project#project for the ID of the current project.) If this attribute is set to a project ID, and that project is authorized for the currently authenticated service account, transit costs will be billed to the that project. The default is nil.

In general, this attribute should be set when first retrieving the owning bucket by providing the user_project option to Project#bucket.

The requester pays feature is currently available only to whitelisted projects.

See also Google::Cloud::Storage::Bucket#requester_pays= and Google::Cloud::Storage::Bucket#requester_pays to enable requester pays for a bucket.
