Description (What does it do?)

Sets the overwrite flag to False when calling ingest_canvas_course from the ContentFileWebhookView

How can this be tested?

• Set this in your backend.local.env file:

  CANVAS_COURSE_BUCKET_NAME=ol-data-lake-landing-zone-production
  

• In a web container shell:

  from learning_resources.models import *
  ContentFile.objects.filter(run__learning_resource__readable_id="canvas-15.060_FA24").delete()

• In a non-container python shell:

  import requests
  import hmac
  import hashlib 
  import json
  from time import time
  data = {
    'content_path': 'canvas/course_content/28777/735a452a9b0cade0449876c4f7d4537b7b49616132d20c8b435bf1e59ab7ac1e.imscc',
    'source':'canvas',
    'timestamp':time()
  }
  payload = bytes(json.dumps(data), 'utf-8')
  secret = "please-change-this"
  computed_signature = hmac.new(secret.encode(), payload, hashlib.sha256).hexdigest()
  requests.post('http://open.odl.local:8063/webhooks/content_files/', json=data, headers={'X-MITLearn-Signature': computed_signature})

• Check your logs, you should see a bunch of relevant activity (may be a delay of a couple minutes until the archive is downloaded)
• Repeat the last request. This time nothing should happen.
