Based on the id of a dataset package, how do I figure out if the package was harvested, by which harvester and what the base URL of that harvester is?
Something along the lines of:
guid = '65715c6e-bbaf-3def-982b-3b5156272da7'
harvest_source = getHarvestSource(guid)
if (harvest_source):
type = harvest_source.type() # whatever was set as the name attribute for this harvester class
base_url = harvest_source.url() # whatever was set as the URL in the admin interface
I've not tried it, but from reading the model I expect something like this:
from ckan.model import Package
id = u'65715c6e-bbaf-3def-982b-3b5156272da7'
dataset = model.Package.get(id)
dataset_was_harvested = bool(len(dataset.harvest_objects) > 0)
if dataset_was_harvested:
ho = dataset.harvest_objects[0] # there's not usually more than 1
source = ho.source # i.e. the harvest source is "the harvester"
source.url # i.e. the harvester's base url
source.type # is also useful
