[ckan-dev] Upload file through the API.

Fri Sep 13 15:59:58 UTC 2013

hi,

I stumbled with the same difficulty.

What I did is: I've created a wrapper module with exposes the Action API 
and some useful methods from the CkanClient.
You can see the module here: http://paste.ubuntu.com/6062158/

The snippet below employs the code I pointed out in order to insert 
files under a given package:

    from datalayer.action.api import ApiClient3

    site_url='http://ckan.localdomain:5000'
    base_location='%s/api' % site_url
    api_key='fb58102b-a16e-48c2-a3ab-48e11dd0354c' # whatever your
    api_key is!

    # administrator
    uadmin='admin'
    padmin='secret'

    # regular user
    uuser='rgomes'
    puser='secret'

    def create_package(cli, pkg, title):
         print('Create package "%s"' % pkg)
         if cli.package_search(q=pkg)['count'] == 0:
    cli.package_create(name=pkg, title=title, license_id='other-closed')
    cli.bulk_update_private(datasets=[pkg])

    def populate_package(cli, pkg, folder, mimetype):
         for root, file in filelist(folder):
             q='%s:%s' % ( 'name', file )
             print(q)
             r = cli.resource_search(query=q)
             if r['count'] == 0:
                 path = '%s/%s' % (root, file)
    print('create', path)
    cli.add_package_resource(pkg, path, resource_type='data',
    mimetype=mimetype)
             elif r['count'] == 1:
                 url = r['results'][0]['url']
                 if url.find(site_url) == -1:
                     url = url.replace('http:/', site_url)
    cli.resource_update(id=r['results'][0]['id'], url=url)
    print('update', url)
                 else:
    print('info', url)
             else:
                 raise RuntimeError(file + ' :: too many entries')

    cli = ApiClient3(base_location=base_location, api_key=api_key,
    http_user=uadmin, http_pass=padmin, verbose=True)

    create_package(cli, 'shares', 'Share prices')
    populate_package(cli, 'shares', folder='~/tmp/upload/csv',
    mimetype='text/csv')

I hope it helps

Cheers
