* fix "existing_package_dict" which wasn't containing metadata_modified (because of the schema in the context) so you never skipped an object.
* fix IntegrityError due to resource revision_id being harvested. No idea why this hasn't caused errors before now.
* "unchanged" is now checked in base instead of ckanharvester - makes sense. Looking at other harvesters, it's normal to return from the import_stage with the value returned from base._create_or_update_package so I've continued with that.
* "unchanged" response is now documented
* better report_status tests in test_queue2.
* Fix extras as a list of dicts
* Fix SOLR dates syntax - needed a Z
* Basic tests for this updated ckan harvester
* Now require CKAN 2.0 to be able to be able to save these packages in package_show form. Take advantage of this now we are such various imports from are definitely available, such as munge_tag.
* Add back compatibility for other harvesters supplying restful-like package_dicts to _create_or_update_package
TODO add back in the ability to harvest pre 2.0 CKANs with the RESTful calls (fallback or maybe configurable)
HTTPError is a subclass of URLError, so catch URLError is enough. I
think the HTTP error code is not as important in this situation, so
catching the more generic error seems like the best solution.
The API call /api/2/rest/package/<id> returns the display name of the
group instead of its ID. To properly match the group, munge the name
before calling /api/2/rest/group
1. Try whenever possible to catch specific exceptions
2. Raise custom exception where appropriate
3. Fix the exception handling in _get_group and _get_organization
First try to get a remote org from the remote Action API, if this fails
try to use the old rest api call, which works on older CKAN versions.
Only if both options fail, its currently not possible to get the remote
organization.
Organizations used to be returned by /api/2/rest/group, this is what the
old implementation used to fetch the information to create the remote
organization on the local instance of CKAN.
With this commit the Action API is used to fetch the same information.
Otherwise CKAN thinks they are uploads, datastore resources, etc, which
it can cause problems eg when displaying the URL of the resource. We
are just linking to the remote resource URL.
The currently implementation returns False when a harvest source is being harvested. This leads to an error on the harvesting job, which in turn tends to confuse users that have no idea of this special implementation. This fix ensures that harvest sources are still ignored, but silently.
If the harvest source belongs to an organization, new datasets should be added
to it. This is already the case in the spatial harvesters.
The remote orgs logic has been kept, with the difference that if for
some reason the remote org can not be assigned, the local one is used.
If the source does not have an organization, none is added.
Remove extras whose values are not strings (e.g. dicts, lists..) from
packages before attempting to create or update the packages on the
target site.
In CKAN 1 it was possible for the values of extras to be other types,
but in CKAN 2 they must be strings, so when harvesting from a CKAN 1 site
into a CKAN 2 site SQLAlchemy would crash when trying to create packages
with non-string extras.
The fix in this commit is to simply remove any non-string extras from
the harvested package. (Alternatively, we could try to convert them to a
string using JSON.)
Fixes#42.
