[ckan-dev] how to create REST api like "/api/action/datastore_search?business=waterfee&cityid=TJ"

Tue May 21 10:43:46 UTC 2013

You can filter results in the datastore_search, using the the filters
parameter [1], eg:

{"business": "waterfee", "cityid": "TJ"}

Note that you will need to use a POST request for the time being, as
there is a bug that prevents the filters parameter from working on GET
requests [2]

Alternatively you can use the datastore_search_sql [3] endpoint and
define a SQL statement. Should be something like:

http://127.0.0.1/api/action/datastore_search_sql?resourceid=XXX&sql=SELECT
* FROM XXX WHERE business = 'waterfee' AND cityid = 'TJ'
