Instance Attribute Details

#user_project ⇒ Object

A boolean value or a project ID string to indicate the project to be billed for operations on the 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 that project. This attribute is required with requester pays-enabled buckets. 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.

See also Google::Cloud::Storage::Bucket#requester_pays= and Google::Cloud::Storage::Bucket#requester_pays.
