Once my resource creation problem has been solved, I have another problem with demo.ckan.org.
After creating the resource, I've created a datastore and upserted some data:
POST http://demo.ckan.org:80/api/3/action/resource_create HTTP/1.1

POST http://demo.ckan.org:80/api/3/action/datastore_upsert HTTP/1.1
{"help": "http://demo.ckan.org/api/3/action/help_show?name=datastore_upsert", "success": true, "result": {"records": [{"attrType": "centigrade", "recvTime": "2015-10-01T06:18:24.72Z", "recvTimeTs": "1443680304", "attrValue": "26.5", "entityType": "Room", "attrName": "temperature", "entityId": "Room1"}], "method": "insert", "resource_id": "12eab044-7853-4907-9879-872550f1376b"}}
The data is there, it can be retrieved through the datastore_search:
curl -s -S -H "Authorization: b4f6cd71-b592-49a3-bb85-9cd5a0f2eb68" "http://demo.ckan.org/api/3/action/datastore_search?resource_id=12eab044-7853-4907-9879-872550f1376b"
{"help": "http://demo.ckan.org/api/3/action/help_show?name=datastore_search", "success": true, "result": {"resource_id": "12eab044-7853-4907-9879-872550f1376b", "fields": [{"type": "int4", "id": "_id"}, {"type": "int4", "id": "recvTimeTs"}, {"type": "timestamp", "id": "recvTime"}, {"type": "text", "id": "entityId"}, {"type": "text", "id": "entityType"}, {"type": "text", "id": "attrName"}, {"type": "text", "id": "attrType"}, {"type": "json", "id": "attrValue"}, {"type": "json", "id": "attrMd"}], "records": [{"attrType": "centigrade", "recvTime": "2015-10-01T06:18:24.720000", "recvTimeTs": 1443680304, "attrMd": null, "attrValue": "26.5", "entityType": "Room", "attrName": "temperature", "entityId": "Room1", "_id": 1}], "_links": {"start": "/api/3/action/datastore_search?resource_id=12eab044-7853-4907-9879-872550f1376b", "next": "/api/3/action/datastore_search?offset=100&resource_id=12eab044-7853-4907-9879-872550f1376b"}, "total": 1}}
Nevetheless, the demo.ckan.org says:
There are no views created for this resource yet.
Not seeing the views you were expecting? Click here for more information.
Here are some reasons you may not be seeing expected views:
- No view has been created that is suitable for this resource
- The site administrators may not have enabled the relevant view plugins
- If a view requires the DataStore, the DataStore plugin may not be enabled, or the data may not have been pushed to the DataStore, or the DataStore hasn't finished processing the data yet
I've always been working with the 2.2 API, and no view had to be created. Now, it seems I have to create such a view with 2.4 API. Is it correct and I have to use the http://docs.ckan.org/en/ckan-2.4.0/api/index.html#ckan.logic.action.create.resource_view_create method? Or is it simply a problem with the portal?
Views aren't automatically created for resource data created directly in the datastore like this. The creation is triggered by resource create assuming there is some data there, but you create an empty resource and add data to it later. As recommended in the other answer, the best route would be to use the API.
It's likely that it is the way that the demo server is set up, I'd suggest using the API call to create the resource_view yourself (unless you have control of the server and configure it differently) is the way to go.
