Not able to create a resource in demo.ckan.org through the API (500 error)

问题

I'm doing some tests with demo.ckan.org, which is running the 2.4 version of the API, AFAIK. Everything works well (organization and dataset creation) except for the resource creation. The resource_create method always returns a 500 error.

This is the curl showing the package where I want to create the resource:

$ curl -X GET "http://demo.ckan.org:80/api/3/action/package_show?id=f2c4125b-27c8-4e07-94d7-d6d0c0b65154" | python -m json.tool

}

And the curl failing when trying to create the resource:

$ curl -X POST "http://demo.ckan.org:80/api/3/action/resource_create" -d '{ "name": "room1_room", "url": "none", "package_id": "f2c4125b-27c8-4e07-94d7-d6d0c0b65154" }' -H "Authorization: MY_API_KEY_IS_SECRET"

回答1:

This appears to be a documentation (and code) bug.

Although format is marked as optional in the documentation, the code requires it to be present (and will unfortunately crash if it isn't).

I've created a ticket at https://github.com/ckan/ckan/issues/2665

As a temporary measure until this is fixed, you can specify the "format" in the JSON you send (it can be empty).
