Los complementos de Google Classroom ya están en fase de disponibilidad general para desarrolladores. Consulta la documentación sobre complementos para obtener más información.
Organiza tus páginas con colecciones
Guarda y categoriza el contenido según tus preferencias.
En esta guía, se explica cómo crear archivos adjuntos de complementos en tu sitio web o aplicación.
Las interacciones son similares a las de crear tareas con los extremos de la API de CourseWork. Implementa este recorrido para permitir que los usuarios creen archivos adjuntos de complementos desde tu sitio web o aplicación.
Flujo de trabajo
En términos generales, el proceso de creación de archivos adjuntos sigue esta secuencia:
Un usuario docente abre tu sitio web o aplicación y selecciona un elemento de contenido para asignárselo a sus estudiantes.
Si el usuario no puede crear archivos adjuntos de complementos, crea una tarea de CourseWork con la URL del contenido seleccionado como un material de vínculo.
Si el usuario puede crear archivos adjuntos de complementos, haz lo siguiente:
Crea una tarea.
Crea un adjunto de complemento que vincule al contenido seleccionado y asócialo a la tarea nueva.
Informa al profesor que la tarea se creó correctamente.
Cada acción se describe en las siguientes secciones.
Comprueba si un usuario puede crear archivos adjuntos de complementos
Puedes crear archivos adjuntos de complementos en nombre de un usuario apto. Un usuario apto es un usuario que es profesor en el curso en el que intentas crear tareas de CourseWork y tiene asignada la licencia de edición de Google Workspace for Education de Teaching & Learning o Education Plus.
Comienza por determinar si el usuario puede crear archivos adjuntos de complementos. Para ello, envía una solicitud al extremo userProfiles.checkUserCapability con el parámetro de capacidad CREATE_ADD_ON_ATTACHMENT. Inspecciona el campo booleano allowed en la respuesta. Un valor true indica que el usuario cumple con los requisitos para crear archivos adjuntos de complementos.
Python
eligibility_response=(classroom_service.userProfiles().checkUserCapability(userId="me",capability="CREATE_ADD_ON_ATTACHMENT",# The previewVersion is necessary while the method is available in the# Workspace Developer Preview Program.previewVersion="V1_20240930_PREVIEW",).execute())is_create_attachment_eligible=(eligibility_response.get('allowed'))print('User eligibility for add-on attachment creation: 'f'{is_create_attachment_eligible}.')
Cómo enrutar al usuario según su elegibilidad
La elegibilidad determina si puedes crear archivos adjuntos de complementos para un usuario.
Usuario no apto
Si el usuario no puede crear archivos adjuntos de complementos, crea una nueva tarea CourseWork con la URL del contenido seleccionado por el usuario como Link.
Python
ifnotis_create_attachment_eligible:coursework={'title':'My CourseWork Assignment with Link Material','description':'Created using the Classroom CourseWork API.','workType':'ASSIGNMENT','state':'DRAFT',# Set to 'PUBLISHED' to assign to students.'maxPoints':100,'materials':[{'link':{'url':my_content_url}}]}assignment=(service.courses().courseWork().create(courseId=course_id,body=coursework).execute())print(f'Link Material assignment created with ID: {assignment.get("id")}')
La respuesta contiene una tarea del curso solicitado con el contenido adjunto. Los usuarios pueden hacer clic en Link para abrir el contenido de tu sitio en una pestaña nueva.

Usuario apto
Haz lo siguiente si el usuario puede crear archivos adjuntos de complementos.
Crea una nueva tarea de CourseWork sin archivos adjuntos.
Crea un archivo adjunto del complemento.
Establece el itemId de AddOnAttachment en el id de la tarea recién creada.
Asegúrate de proporcionar URLs al contenido seleccionado por el usuario para cada vista que admitas.

Implement this journey to allow users to create add-on attachments\nfrom your website or application.\n| **Important:** We strongly recommend implementing this attachment creation flow if you already create [`CourseWork`](/workspace/classroom/reference/rest/v1/courses.courseWork) assignments. Extending a CourseWork implementation lets you convert many more users to your add-on and requires little additional work.\n\nWorkflow\n--------\n\nAt a high level, the attachment creation journey follows this sequence:\n\n1. A teacher user opens your website or app. They select a piece of content to assign to their students.\n2. [Check that the user can create add-on attachments](#check-whether).\n3. If the user **can't** create add-on attachments, create a CourseWork assignment with the URL to the selected content as a Link Material.\n4. If the user **can** create add-on attachments, do the following:\n 1. Create an assignment.\n 2. Create an add-on attachment that links to the selected content and associate it with the new assignment.\n5. Inform the teacher that the assignment has been created successfully.\n\nEach action is described in the following sections.\n\nCheck whether a user can create add-on attachments\n--------------------------------------------------\n\nYou can create add-on attachments on behalf of an eligible user. An eligible\nuser is a user who is a teacher in the course you are trying to create\nCourseWork assignments in **and** has the Teaching \\& Learning or Education Plus\nGoogle Workspace for Education edition license assigned to them.\n| **Key Point:** Eligibility to create add-on attachments may be different for each user and can change over time. Always check the user's eligibility before attempting to create add-on attachments.\n| **Important:** Eligibility checks using the Classroom API are in public preview and available in preview version `V1_20240930_PREVIEW` and later. To use API methods in public preview, you must be part of the [Google Workspace Developer Preview Program](/workspace/preview) and [perform additional setup](/workspace/classroom/reference/preview) beyond typical Classroom API usage.\n\nBegin by determining whether the user can create add-on attachments. You can do\nso by issuing a request to the [`userProfiles.checkUserCapability`](/workspace/classroom/reference/rest/v1/userProfiles/checkUserCapability) endpoint\nwith the `CREATE_ADD_ON_ATTACHMENT` capability parameter. Inspect the boolean\n`allowed` field in the response; a `true` value indicates that the user is\neligible to create add-on attachments.\n**Warning:** Requests to create add-on attachments for users with the `CREATE_ADD_ON_ATTACHMENT` capability are not guaranteed to succeed. For example, a user with the capability will receive a `403` response error if you attempt to create add-on attachments on their behalf in a course in which the user is not a teacher. \n\n### Python\n\n eligibility_response = (\n classroom_service.userProfiles()\n .checkUserCapability(\n userId=\"me\",\n capability=\"CREATE_ADD_ON_ATTACHMENT\",\n # The previewVersion is necessary while the method is available in the\n # Workspace Developer Preview Program.\n previewVersion=\"V1_20240930_PREVIEW\",\n ).execute()\n )\n is_create_attachment_eligible = (\n eligibility_response.get('allowed')\n )\n print('User eligibility for add-on attachment creation: '\n f'{is_create_attachment_eligible}.')\n\nRoute the user based on their eligibility\n-----------------------------------------\n\nEligibility determines whether you can create add-on attachments for a user.\n| **Important:** Add-ons offer significant user experience advantages. Always create add-on attachments for eligible users.\n\n### Ineligible user\n\nIf the user *can't* create add-on attachments, then create a new [`CourseWork`](/workspace/classroom/reference/rest/v1/courses.courseWork)\nassignment with the user-selected content URL as a [`Link`](/workspace/classroom/reference/rest/v1/Material). \n\n### Python\n\n if not is_create_attachment_eligible:\n coursework = {\n 'title': 'My CourseWork Assignment with Link Material',\n 'description': 'Created using the Classroom CourseWork API.',\n 'workType': 'ASSIGNMENT',\n 'state': 'DRAFT', # Set to 'PUBLISHED' to assign to students.\n 'maxPoints': 100,\n 'materials': [\n {'link': {'url': my_content_url}}\n ]\n }\n\n assignment = (\n service.courses()\n .courseWork()\n .create(courseId=course_id, body=coursework)\n .execute()\n )\n\n print(\n f'Link Material assignment created with ID: {assignment.get(\"id\")}'\n )\n\nThe response contains an assignment in the requested course with the content\nattached. Users can click the `Link` to open the content in your site in a new\ntab.\n\n**Figure 1.** Teacher view of a draft CourseWork assignment with Link Material.\n\n### Eligible user\n\nDo the following if the user *can* create add-on attachments.\n\n1. Create a new `CourseWork` assignment without any attachments.\n2. Create an add-on attachment.\n - Set the[`AddOnAttachment`](/workspace/classroom/reference/rest/v1/courses.courseWork.addOnAttachments#resource:-addonattachment)'s `itemId` to the `id` of the newly created assignment.\n - Ensure that you provide URLs to the user-selected content for [each View\n that you support](/workspace/classroom/add-ons/get-started/iframes/iframes-overview).\n\n### Python\n\n if is_create_attachment_eligible:\n coursework = {\n 'title': 'My CourseWork Assignment with Add-on Attachment',\n 'description': 'Created using the Classroom CourseWork API.',\n 'workType': 'ASSIGNMENT',\n 'state': 'DRAFT', # Set to 'PUBLISHED' to assign to students.\n 'maxPoints': 100,\n }\n\n assignment = (\n classroom_service.courses()\n .courseWork()\n .create(courseId=course_id, body=coursework)\n .execute()\n )\n\n print(\n f'Empty assignment created with ID: {assignment.get(\"id\")}'\n )\n\n attachment = {\n 'teacherViewUri': {'uri': teacher_view_url},\n 'studentViewUri': {'uri': student_view_url},\n 'studentWorkReviewUri': {'uri': grade_student_work_url},\n 'title': f'Test Attachment {test_label}',\n }\n\n add_on_attachment = (\n service.courses()\n .courseWork()\n .addOnAttachments()\n .create(\n courseId=course_id,\n itemId=assignment.get(\"id\"), # ID of the new assignment.\n body=attachment,\n )\n .execute()\n )\n\n print(\n f'Add-on attachment created with ID: {add_on_attachment.get(\"id\")}'\n )\n\n| **Note:** An add-on token is not required if creating an attachment on an assignment that you created.\n\nThe add-on appears as an [attachment card](/workspace/classroom/add-ons/get-started/attachments-journey) in Classroom. The URLs\nspecified in the request open in the appropriate\n[iframe for each View](/workspace/classroom/add-ons/get-started/iframes/iframes-overview)."]]
