Attributes

• copyHistory (type: list(GoogleApi.Classroom.V1.Model.CopyHistory.t), default: nil) - Output only. Identifiers of attachments that were previous copies of this attachment. If the attachment was previously copied by virtue of its parent post being copied, this enumerates the identifiers of attachments that were its previous copies in ascending chronological order of copy.
• courseId (type: String.t, default: nil) - Immutable. Identifier of the course.
• dueDate (type: GoogleApi.Classroom.V1.Model.Date.t, default: nil) - Date, in UTC, that work on this attachment is due. This must be specified if due_time is specified.

• itemId (type: String.t, default: nil) - Immutable. Identifier of the Announcement, CourseWork, or CourseWorkMaterial under which the attachment is attached. Unique per course.
• maxPoints (type: float(), default: nil) - Maximum grade for this attachment. Can only be set if studentWorkReviewUri is set.

The URI will be opened in an iframe with the courseId, itemId, itemType, attachmentId, and submissionId query parameters set. This is the same submissionId returned in the AddOnContext.studentContext field when a student views the attachment. If the URI is omitted or removed, max_points will also be discarded.
