[ckan-dev] Creating resource with upload from an extension

Fri Apr 29 11:26:06 UTC 2016

Yeah, the url parameter should not be required when doing uploads via the API.
See here:
https://github.com/ckan/ckan/pull/1641#issuecomment-160893234
And here:
https://github.com/ckan/ckan/issues/2769

Setting it to some random string worked for me, e.g.

res = ckan.action.resource_create(
         package_id='2ad3c9de-502c-403a-8b03-bfc619697ff2',
         url='dummy-value',
         name='my file',
         description='my upload with CKANAPI',
         upload=open('./myfile.csv')
     )

Best regards,
Jonas Oppenlaender

Hi
Your solution does not produce any error, although if I have resource_dict['url'] = None,
[ckanext.harvest.model] Validation Error: {'URL': 'Missing value'}

If I had a value I get that value on the resource link, not a resource pointing to the filestore (or ckan internal storage).

Any ideas?
I'm thinking on using the API inside the extension, but this is a very hacky solution..

Hi Pedro,

You can just pass it an open file pointer, like this:
resource_dict['upload'] = open(‘/path/to/file’, ‘rb’)

If you use an already open file, you might need to reset the current position before calling the API:
existingfilepointer.seek(0)

Hi
I have a custom extension which does some parsing on files and then adds them to the dataset created. How should I use the field upload to pass a file? Any ideas?

resource_dict={}
resource_dict['package_id'] = package_id
resource_dict['upload'] = ????
resource_dict['name'] = 'Product Download'
oi = plugins.toolkit.get_action('resource_create')(context,resource_dict)
