CKAN Harvester for SALSAH

Config options

The following config options can be set in the Configuration-field of the harvester:

limit

  • Type: Integer
  • Default: 3

user

  • Type: String
  • Default: harvest

Example of options usage:

{
  "limit": 3,
  "user": "harvest"
}

Developing without running jobs manually

It's quite awkward and slow to run the harvesters on the command line when you are developing a harvester. To solve this issue I have setup the tests from the ckan harvester and tweaked them a bit so we can use them to get feedback quickly on what we are doing.

The important stuff is located in ckanext-salsah/ckanext/salsah/tests/test_queue.py

A TestSalsahHarvester inherits from SalsahHarvester. Only the info is mocked, the other methods are kept. TestHarvestqueue then calls e.g. gather_stage from the original harvester. You can then either mock methods in the test or operate on the real harvester and run the tests to see what it does:

. ~/default/bin/activate
cd /vagrant/ckanext-salsah

nosetests --logging-filter=ckanext.salsah.harvester --ckan --with-pylons=test.ini ckanext/salsah/tests

In this example the logging filter is used to only show messages of the harvester.
