[ckan-dev] Resource preview error on non-root ckan

Fri Jul 4 08:55:24 UTC 2014

Hi, 

In production.ini i  have :

ckan.site_url = http://example.com
After i changed in ckan.site_url = http://example.com/ckan, when creating new resource , 
upload is executing ok. Resource url showed is http://example.com/ckan/ckan/storage/f/2014-07-04T10%3A31%3A10.088Z/test.csv  (incorrect, ckan is twice). Now  error show up on download and on view new resource I just uploaded.

Error message from datapusher.error is:

Fetching from: http://example.com/ckan/ckan/storage/f/2014-07-04T10%3A12%3A23.597Z/test.csv

[Fri Jul 04 13:12:41 2014] [error] JobError: Invalid HTTP response: HTTP Error 404: Not Found

I don't think it id DNS problem because i  replaced the domain name with ip address and error is the same.

URL in this  line:

'[Thu Jul 03 13:55:45 2014] [error] JobError: CKAN bad response. Status code: 404 Not Found. At: http://example.com/api/3/action/resource_show.'

is incorrect , /ckan is missing and i don't know which settings should be done to obtain correct url .

Thanks to all
Eli

You need to also set http://docs.ckan.org/en/latest/maintaining/configuration.html#ckan-site-url correctly.
