[ckan-dev] Getting resources from packages via the ckanapi

Thu Feb 23 20:14:37 UTC 2017

Tim,

I had tried that approach earlier with this syntax which seems to match what works for the organization_show:
packageObj = ckan.action.package_show(id=package['id'])
But when I attempt to see what I retrieved like so:
pprint (packageObj)
All that I get is
-1

I thought perhaps it was a problem with my install of ckanapi so I upgraded from 3.6 to 4.0 but that did not fix the issue.

The syntax you suggested seems to have a problem but I also tried this variation:

packageObj = ckan.action.package_show('id:' + package['id']) #note addition of plus sign...

which throws:
TypeError: action() takes exactly 0 arguments (1 given)

Still plunking away...

Andrew

Hi Andrew,

Once you have the package id, you can :

                 packageObj = ckan.action.package_show('id:' package['id'])

This will return you the package object with all the resources included. You can loop through the resources if you want but I believe all the resource metadata is provided.

Regards Tim

Hoping somebody can assist:  I am attempting to create a report for one of my ckan instances that lists all the organizations, and then all of their packages along with the id of the packages' resource (we have only one resource per package).  However, I do not seem to be able to link to the resource id via API calls.

Here is what I have so far:

organizations = ckan.action.organization_list(include_datasets ='True')
for organization in organizations:

         packages= orgDetails['packages']

         for package in packages:

                 #And here is where it breaks down.... Here are a few of the many searches / shows I have tried:

                 resourceObj = ckan.action.resource_search(query='package_id:' +package['id'])

                    #which returns: {u'query': u'Field "package_id" not recognised in resource_search.', u'__type': u'Validation Error'}

                 revisionObj = ckan.action.revision_show(id=package['revision_id'])

                    #which just brings back information already knows about the revision.

While iterating through the package information I seem unable to get the related resources.  I have tried all sorts of queries using what info I have from the package to get the related resources.

What can I use to link from the package list found in the return object from organization_show to get resources?

Many thanks,
