Quản lý khóa học

Tài nguyên khoá học đại diện cho một lớp học, chẳng hạn như "Toán 127", cùng với giáo viên được chỉ định, danh sách học viên và siêu dữ liệu.

Mỗi khoá học được xác định bằng một mã nhận dạng duy nhất do máy chủ chỉ định. Ngoài ra, tên có thể được liên kết với một khoá học và được dùng thay cho mã nhận dạng duy nhất. Mỗi tên, được gọi là Tên đại diện, tồn tại trong một không gian tên hạn chế những người có thể tạo và xem tên đó.

Hệ thống hỗ trợ hai không gian tên:

  • Miền: Không gian tên miền hữu ích cho việc tạo các bí danh mà tất cả người dùng cần truy cập, nhưng không dành riêng cho bất kỳ chương trình nào. Ví dụ: bạn nên tạo trang thông tin thay thế cho một khoá học, chẳng hạn như MATH 127 và COMSCI 127, trong không gian tên miền. Chỉ quản trị viên miền mới có thể tạo bí danh trong không gian tên miền, nhưng tất cả người dùng trong miền đều có thể xem được.
  • Dự án nhà phát triển: Không gian tên dự án nhà phát triển hữu ích cho việc quản lý các bí danh dành riêng cho một ứng dụng. Ví dụ: một ứng dụng sử dụng giá trị nhận dạng thay thế cho các khoá học có thể tạo bí danh để liên kết giá trị nhận dạng của ứng dụng đó với các khoá học trên Lớp học. Các bí danh được tạo trong không gian tên này được liên kết với một dự án Bảng điều khiển API của Google cụ thể. Mọi người dùng ứng dụng đều có thể tạo và xem các bí danh trong không gian tên cho dự án nhà phát triển của ứng dụng đó.

Tạo khoá học

Bạn có thể thêm một khoá học bằng phương thức courses.create(), như trong mẫu sau:

Khi tạo khoá học, bạn có thể tuỳ ý thêm siêu dữ liệu như mô tả khoá học, thời gian hoặc vị trí.

Để tạo một khoá học, người dùng đưa ra yêu cầu phải có các quyền thích hợp trong hồ sơ người dùng của họ.

Theo mặc định, các khoá học được tạo với courseState được đặt thành PROVISIONED; tuy nhiên, bạn có thể ghi đè giá trị này thành ACTIVE. Nếu khoá học được tạo ở trạng thái PROVISIONED, thì giáo viên được xác định trong ownerId phải chấp nhận lớp học trong giao diện người dùng Lớp học hoặc khoá học phải được cập nhật thông qua API để thay đổi courseState thành ACTIVE và cung cấp cho học viên.

Truy xuất thông tin chi tiết về khoá học

Bạn có thể truy xuất siêu dữ liệu của một khoá học bằng phương thức courses.get(), như trong mẫu sau:

Chuyển quyền sở hữu khoá học

Quản trị viên miền có thể chuyển quyền sở hữu khoá học giữa các giáo viên trong miền của họ bằng cách gọi các phương thức sau:

  1. Trước tiên, hãy gọi teachers.create() để thêm giáo viên vào khoá học nếu họ chưa phải là người cùng dạy.

  2. Sau đó, hãy gọi courses.patch() và chỉ định email hoặc mã nhận dạng người dùng của đồng giáo viên trong trường ownerId của đối tượng yêu cầu để cập nhật chủ sở hữu khoá học.
