Administrar profesores y alumnos

Los alumnos y los profesores son asignaciones específicas entre un perfil de usuario y un curso, y representan la función de ese usuario en el curso. Las designaciones de alumnos y profesores no son globales: se puede asignar a un usuario como profesor para un curso y como alumno de otro. La designación "alumno" o "profesor" representa un conjunto de permisos para un usuario específico en un curso en particular.

Alumnos
Un recurso de alumno representa a un usuario que está inscrito como alumno en un curso específico. Los alumnos pueden ver los detalles del curso y los profesores correspondientes.
Profesores
Los recursos para profesores representan a un usuario que dicta un curso específico. Los profesores pueden ver y cambiar los detalles del curso, ver profesores y alumnos, y administrar profesores y alumnos adicionales.

Los alumnos y los profesores se identifican por el ID único o la dirección de correo electrónico del usuario, como lo muestra el SDK de Admin de Google. El usuario actual también puede hacer referencia a su propio ID con la abreviatura "me".

Agregar directamente

Los administradores de dominio pueden omitir el flujo de invitaciones y agregar directamente a los usuarios del dominio como profesores o alumnos a los cursos de su dominio. Un curso se considera dentro del dominio del administrador si el propietario del curso está en el dominio del administrador. Para los usuarios o cursos fuera del dominio de un administrador de dominio autenticado, las aplicaciones deben obtener el consentimiento del usuario mediante el envío de una invitación con el método invitations.create().

Cómo agregar o quitar profesores

Los administradores de dominio pueden agregar profesores directamente dentro de su dominio a los cursos con teachers.create(), como se muestra en el siguiente ejemplo:

Si agregas alumnos en nombre de un profesor autenticado, debes usar el método invitations.create().

Puedes quitar a un alumno de un curso con el método students.delete(). Esto solo quita al alumno especificado del curso y no afecta su inscripción en otros cursos o su perfil de usuario.

Recuperar los cursos de un usuario

Para recuperar una lista de cursos para un alumno o un profesor, usa courses.list() y proporciona la studentId o teacherId correspondiente del usuario.

Recuperar el perfil de un usuario

Para recuperar el perfil resumido, incluidos el ID y el nombre de un usuario, llama a userProfiles.get() con el ID, el correo electrónico o el "yo" del usuario que realiza la solicitud.

Para recuperar el campo emailAddress, debes incluir el permiso classroom.profile.emails.

El ID que se muestra corresponde al recurso de usuarios de la API de Directory que contiene las coincidencias de studentId o teacherId.
