[ckan-dev] datastore upsert api

[Sam Leitner]

Oops, looks like I was confused about key labeling. Sorry for the spam. In
case other people run into similar problems, here's an example bash script
demoing most of the datastore API functionality:

API_KEY='<INSERT YOUR API KEY>'
SITE_API='<CKAN WEBSITE:PORT>/api/3/action/'
RES_ID='<INSERT CREATED RESOURCE ID>'

#create
echo '----------------create'
curl -X POST ${SITE_API}/datastore_create -H "Authorization: ${API_KEY}" -d
'{"force":"true", "resource_id":"'${RES_ID}'", "primary_key":["name"],
"fields": [{"id":"name"},{"id":"tab", "type":"json"}],"records" : [
{"name": "datadict", "tab": [{"item1_int":1,"item2_txt":"xyz"}] } ]}'; echo
'';
curl -X POST ${SITE_API}/datastore_create -H "Authorization: ${API_KEY}" -d
'{"force":"true", "resource_id":"'${RES_ID}'", "records" : [ {"name":
"otherdata", "tab": [{"k1":1,"k2":2}] } ]}'; echo '';

#show
echo '----------------show'
curl -X GET ${SITE_API}/datastore_search?resource_id=${RES_ID} -H
"Authorization: ${API_KEY}"; echo '';

#update
echo '----------------update'
curl -X POST ${SITE_API}/datastore_upsert -H "Authorization: ${API_KEY}" -d
'{"force":"true", "resource_id":"'${RES_ID}'", "method":"upsert", "records"
: [ {"name": "datadict", "tab": [{"item1_int":4444,"item2_txt":1111}] }
]}'; echo '';

#show
echo '----------------show'
curl -X GET ${SITE_API}/datastore_search?resource_id=${RES_ID} -H
"Authorization: ${API_KEY}"; echo '';

#delete
echo '----------------delete otherdata'
curl -X POST ${SITE_API}/datastore_delete -H "Authorization: ${API_KEY}" -d
'{ "force":"true", "resource_id":"'${RES_ID}'",
"filters":{"name":"otherdata"} }'; echo '';
#show
echo '----------------show'
curl -X GET ${SITE_API}/datastore_search?resource_id=${RES_ID} -H
"Authorization: ${API_KEY}"; echo '';
#delete
echo '----------------delete'
curl -X POST ${SITE_API}/datastore_delete -H "Authorization: ${API_KEY}" -d
'{ "force":"true", "resource_id":"'${RES_ID}'", "filters":{} }'; echo '';
