[ckan-dev] DataStore, DROP TABLE and recreate work, but DROP TABLE and recreate as VIEW fails.

[Michael Nielsen]

Ok, after a lot of debugging I found out that in:
ckanext/datastore/logic/action.py
there's this check:

    if not data_dict['resource_id'] in WHITELISTED_RESOURCES:

        # Replace potential alias with real id to simplify access checks

        resource_id = results.fetchone()[0]

        if resource_id:

            data_dict['resource_id'] = resource_id


        p.toolkit.check_access('datastore_search', context, data_dict)

if I comment that entire check (remove it), then everything works with real
views!

Can anyone comment on this, pros and cons?
