6. Accessions

update_accession implementation

We need three pieces of information

1. our repo_id
2. our accession_id (the numeric one from the uri, not id_0, id_1, etc.)
3. our updated accession model

Notice the similarity to update_agent.

    def update_accession(api_url, auth_token, repo_id, accession_id, accession_model):
        '''update an accession record and return a results message'''
        data = json.JSONEncoder().encode(accession_model).encode('utf-8')
        url = api_url+'/repositories/'+str(repo_id)+'/accessions/'+str(accession_id)
        req = urllib.request.Request(
             url = url,
             data = None,
             headers = {'X-ArchivesSpace-Session': auth_token},
             method = 'POST')
        try:
            response = urllib.request.urlopen(req, data)
        except urllib.error.URLError as e:
            print(e.reason)
            return None
        except urllib.error.HTTPError as e:
            print(e.code)
            print(e.read())
            return None
        src = response.read().decode('utf-8')
        return json.JSONDecoder().decode(src)

And our test in the if block

        # Test update_accession
        print('Test update_accession()')
        accession_id = int(input('Enter accession id to uppdate: '))
        accession_model = list_accession(api_url, auth_token, repo_id, accession_id)
        accession_model['title'] = input('Enter new title: ')
        result = update_accession(api_url, auth_token, repo_id, accession_id, accession_model)
        print('update result', json.dumps(result, indent=4))
