  1. import json
  2. import secret

  3. # Open the Cedar template in your browser, paste the url between the triple quotes in its completeness
  4. # This script will extract the template-instance id (URL is non working example)
  5. template_instance_url = '''
  6. https://cedar.metadatacenter.org/instances/edit/https://repo.metadatacenter.org/template-instances/74eb7227-205d-48bd-b200-c79f356ac470?folderId=https:%2F%2Frepo.metadatacenter.org%2Ffolders%2F61f487eb-a59a-4ac8-bc28-21b38cb81ebb
  7. '''

  8. # Getting the Cedar Secret key from secert.py
  9. CedarApiKey = secret.CedarApiKey

  10. # needed to codify the url needed for Cedar get and put
  11. def codify_url(uri):
  12.     return uri.replace('/', '%2F').replace(':', '%3A')


  13. # getting the Template Instance

  14. ## extract the template_instance id
  15. find_string = 'template-instances/'
  16. pos = template_instance_url.find(find_string) + len(find_string)
  17. template_instance = template_instance_url[pos:pos+36]

  18. ## reconstructing the URL needed for get
  19. base_url = 'https://resource.metadatacenter.org/template-instances/'
  20. url = codify_url('https://repo.metadatacenter.org/template-instances/')
  21. url = base_url + url + template_instance
  22. # print(url)

  23. headers = {'Content-Type': 'application/json', 'Authorization': CedarApiKey}

  24. ## geting the Cedar template
  25. req = requests.get(url, headers=headers) #, files=files)
  26. template = json.loads(req.content)
  27. for item in template.items:
  28.     print(item)

  29. ### do your stuff with template ###
  30. # examine the above structure to assign new values
  31. # e.g. template['Date']['@value'] = date_string #'2021-05-27'

  32. ## writing to Cedar
  33. headers = {'Content-Type': 'application/json', 'Authorization': CedarApiKey, 'Accept': 'application/json'}
  34. response = requests.put(url, data=json.dumps(template), headers=headers)

  35. if str(response) == '<Response [200]>':
  36.     print('Cedar is successfully updated')
  37. else:
  38.     print('Houston we had a problem updating Cedar, errorcode: ' + str(response))
