गतिविधि-प्रकार अटैचमेंट

Python

हमारे दिए गए उदाहरण में, यह create_attachments तरीके में है, जो webapp/attachment_routes.py फ़ाइल.

attachment = {
    # Specifies the route for a teacher user.
    "teacherViewUri": {
        "uri":
            flask.url_for(
                "load_activity_attachment",
                _scheme='https',
                _external=True),
    },
    # Specifies the route for a student user.
    "studentViewUri": {
        "uri":
            flask.url_for(
                "load_activity_attachment",
                _scheme='https',
                _external=True)
    },
    # Specifies the route for a teacher user when the attachment is
    # loaded in the Classroom grading view.
    # The presence of this field marks this as an activity-type attachment.
    "studentWorkReviewUri": {
        "uri":
            flask.url_for(
                "view_submission", _scheme='https', _external=True)
    },
    # The title of the attachment.
    "title": f"Attachment {attachment_count}",
}

पिछले चरणों से, SQLite और flask_sqlalchemy लागू करने की प्रक्रिया को बढ़ाएं.

उस फ़ाइल पर जाएं जिसमें आपने पिछली टेबल तय की हैं (models.py अगर आप हमारे दिए गए उदाहरण को फ़ॉलो कर रहे हैं). यहां पर: फ़ाइल के निचले हिस्से पर जाएं.

# Database model to represent a student submission.
class Submission(db.Model):
    # The attachmentId is the unique identifier for the attachment.
    submission_id = db.Column(db.String(120), primary_key=True)

    # The unique identifier for the student's submission.
    attachment_id = db.Column(db.String(120), primary_key=True)

    # The student's response to the question prompt.
    student_response = db.Column(db.String(120))

अपने अटैचमेंट के साथ, नई Submission क्लास को सर्वर फ़ाइल में इंपोर्ट करें हैंडलिंग रूट.

Python

हमारे दिए गए उदाहरण में, यह load_activity_attachment तरीके में है webapp/attachment_routes.py फ़ाइल.

# Issue a request to the courseWork.getAddOnContext endpoint
addon_context_response = classroom_service.courses().courseWork(
).getAddOnContext(
    courseId=flask.session["courseId"],
    itemId=flask.session["itemId"]).execute()

# One of studentContext or teacherContext will be populated.
user_context = "student" if addon_context_response.get(
    "studentContext") else "teacher"

# If the user is a student...
if user_context == "student":
    # Extract the submissionId from the studentContext object.
    # This value is provided by Google Classroom.
    flask.session["submissionId"] = addon_context_response.get(
            "studentContext").get("submissionId")

Python

यहां दिए गए उदाहरण में, load_activity_attachment तरीका ऊपर दिया गया है.

# Issue a request to get the status of the student submission.
submission_response = classroom_service.courses().courseWork(
).addOnAttachments().studentSubmissions().get(
    courseId=flask.session["courseId"],
    itemId=flask.session["itemId"],
    attachmentId=flask.session["attachmentId"],
    submissionId=flask.session["submissionId"]).execute()

Python

यहां दिए गए उदाहरण में, load_activity_attachment तरीका ऊपर दिया गया है.

# Look up the attachment in the database.
attachment = Attachment.query.get(flask.session["attachmentId"])

message_str = f"I see that you're a {user_context}! "
message_str += (
    f"I've loaded the attachment with ID {attachment.attachment_id}. "
    if user_context == "teacher" else
    "Please complete the activity below.")

form = activity_form_builder()

if form.validate_on_submit():
    # Record the student's response in our database.

    # Check if the student has already submitted a response.
    # If so, update the response stored in the database.
    student_submission = Submission.query.get(flask.session["submissionId"])

    if student_submission is not None:
        student_submission.student_response = form.student_response.data
    else:
        # Store the student's response by the submission ID.
        new_submission = Submission(
            submission_id=flask.session["submissionId"],
            attachment_id=flask.session["attachmentId"],
            student_response=form.student_response.data)
        db.session.add(new_submission)

    db.session.commit()

    return flask.render_template(
        "acknowledge-submission.html",
        message="Your response has been recorded. You can close the " \
            "iframe now.",
        instructions="Please Turn In your assignment if you have " \
            "completed all tasks."
    )

# Show the activity.
return flask.render_template(
    "show-activity-attachment.html",
    message=message_str,
    image_filename=attachment.image_filename,
    image_caption=attachment.image_caption,
    user_context=user_context,
    form=form,
    responses=response_strings)

उपयोगकर्ताओं के बीच अंतर करने के लिए, सबमिट को बंद करें फ़ंक्शन का इस्तेमाल करके, Teacher View में सही जवाब दिखाया जा सकता है.

हमारे दिए गए उदाहरण में, यह webapp/attachment_routes.py फ़ाइल में है.

    # For the sake of brevity in this example, we'll skip the conditional logic
    # to see if we need to authorize the user as we have done in previous steps.
    # We can assume that the user that reaches this route is a teacher that has
