[ckan-dev] Datastore error

Fri Oct 10 02:35:27 UTC 2014

Hi Maurizio,

When you upload a file to CKAN, it's created on the Datastore. To avoid
that the data that exists on the Datastore becomes different than the data
of the original file, the Datastore throws this error when you try to call
datastore_create with a resource_id AND passing records. What you're trying
to do is updating the resource "2039e10a-869a-4da1-a909-0d8ac520f115"
adding these new records.

If that's really what you want to do, you need to send another parameter
"force": True, like:

curl -X POST http://127.0.0.1:5000/api/3/action/datastore_create -H
> "Authorization: 4d9c2123-5d25-4913-96ef-ac20cec1cf67" -d
> '{"resource_id": "2039e10a-869a-4da1-a909-0d8ac520f115", "fields": [
> {"id": "a"}, {"id": "b"} ], "records": [ { "a": 1, "b": "xyz"}, {"a": 2,
> "b": "zzz"} ], "force": True}

This part of the documentation needs to be improved.

Cheers,
