Zarządzanie nauczycielami i uczniami

Uczniowie i nauczyciele to konkretne odwzorowania między profilem użytkownika a kursem, które wskazują rolę użytkownika w kursie. Użytkownik może być nauczycielem w jednym kursie, a uczniem w innym. Oznaczenie „uczeń” lub „nauczyciel” oznacza zestaw uprawnień danego użytkownika w danym kursie.

Uczniowie
Zasób „Student” reprezentuje użytkownika, który jest uczniem na konkretnych zajęciach. Uczniowie mogą wyświetlać szczegóły zajęć i nauczycieli prowadzących te zajęcia.
Nauczyciele
Zasób Nauczyciel reprezentuje użytkownika, który prowadzi konkretny kurs. Nauczyciele mogą wyświetlać i zmieniać szczegóły kursu, wyświetlać nauczycieli i uczniów oraz zarządzać dodatkowymi nauczycielami i uczniami.

Uczniowie i nauczyciele są identyfikowani na podstawie unikalnego identyfikatora lub adresu e-mail użytkownika zwróconego przez interfejs Directory API. Bieżący użytkownik może też odwoływać się do swojego identyfikatora za pomocą skrótu "me".

Dodawanie bezpośrednie

Administratorzy domen mogą pominąć proces zapraszania i bezpośrednio dodawać użytkowników z ich domeny jako nauczycieli lub uczniów do zajęć w domenie. Kurs jest uznawany za znajdujący się w domenie administratora, jeśli właściciel kursu znajduje się w domenie administratora. W przypadku użytkowników lub zajęć spoza domeny uwierzytelnionego administratora domeny aplikacje muszą uzyskać zgodę użytkownika, wysyłając zaproszenie za pomocą metody invitations.create().

Dodawanie i usuwanie nauczycieli

Administratorzy domen mogą bezpośrednio dodawać nauczycieli z ich domeny do zajęć za pomocą teachers.create(), jak pokazano w tym przykładzie:

Jeśli dodajesz dodatkowych nauczycieli w imieniu nauczyciela uwierzytelnionego, musisz użyć metody invitations.create().

Dodatkowych nauczycieli możesz usunąć z zajęć za pomocą metody teachers.delete(). Spowoduje to usunięcie tylko określonego nauczyciela z kursu i nie wpłynie na jego przypisanie do innych kursów ani na jego profil użytkownika.

Jeśli dodajesz uczniów w imieniu uwierzytelnionego nauczyciela, musisz użyć metody invitations.create().

Ucznia możesz usunąć z zajęć za pomocą metody students.delete(). Spowoduje to usunięcie tylko wskazanego studenta z kursu i nie wpłynie na jego rejestrację w innych kursach ani na jego profil użytkownika.

Pobieranie kursów użytkownika

Aby pobrać listę kursów dla ucznia lub nauczyciela, wywołaj funkcję courses.list() i podaj odpowiedni identyfikator studentId lub teacherId użytkownika.

Pobieranie profilu użytkownika

Aby pobrać skrócony profil użytkownika, w tym jego identyfikator i nazwę, wywołaj funkcję userProfiles.get(), podając identyfikator użytkownika, jego adres e-mail lub „me” (ja).

Aby pobrać pole emailAddress, musisz uwzględnić zakres classroom.profile.emails.

Zwrócony identyfikator odpowiada zasobowi Directory API Users zawierającego pasujące wartości studentId lub teacherId.

Zarządzanie właścicielami zajęć

Administratorzy domen mogą przenosić własność zajęć między nauczycielami. Ważne informacje znajdziesz w sekcji Przenoszenie własności zajęć.
