[ckan-dev] How to access an array in extra-fields ?

Mon May 2 20:44:50 UTC 2011

Pascal,

It's great you're using our API and pushing us on it! Allow me to
summarise your issues (correct if necessary) and where we're at with
them.

* http://trac.ckan.org/ticket/1116 Api search loses boolean q options
(filter_by_openness)
  * FIXED

* http://trac.ckan.org/ticket/1112 Allow api searching for all packages (q=*)
  * FIXED (use q=)

* http://trac.ckan.org/ticket/1121 JSON extras appear in package edit
form mangled
  * To be assigned

* http://trac.ckan.org/ticket/1122 JSON Extra data not searchable
  * @pudo I notice you tackling solr indexing of lists/tuples in
ckanext-solr cset:ecc2d69df991 so have updated to use this on ckan.net
and reindexed, but #1122 still seems an issue - any chance you can
take a look

Storing lists, tuples & dicts in extra fields is something we want to
support for harvesting, but I wasn't aware this was a feature
wanted/needed be front end users. I guess you could store the list
quoted, so it is stored as a JSON string, rather than something that
acts like a collection and hence confuses the form & search, but would
that make life harder for you Pascal?

BTW I failed to mention you can POST parameters. These examples (now)
all give the same response:

curl 'http://ckan.net/api/1/search/package?q=lobid&filter_by_openness=1'
curl 'http://ckan.net/api/1/search/package' -d 'q=lobid&filter_by_openness=1'
curl 'http://ckan.net/api/1/search/package' -d '{"q": "lobid",
"filter_by_openness": "1"}'
