[ckan-dev] FileStore integration with Apache does not work

[User66]

I did following test:

1) Start the paster web server.
2) Add a resource to a dataset and upload an image to it (via the port 5000 web service)
3) Stop the paster web server (and delete the session files in "pyenv/src/ckan/data/sessions" due to potential permission conflict ckan user vs. www user)
4) Access CKAN via Apache web service. Result: The image is still available via the Apache web service. But the "Upload" button/link does not appear!

So, the general integration to the storage area works, but to some extent the Phython API is not fully working with Apache. Is there something to consider regarding the API path described at http://docs.ckan.org/en/latest/filestore-api.html ? Since after initial Apache integration I got errors like

 [Mon Mar 25 11:59:57 2013] [error] [client xxx] File does not exist: /srv/www/htdocs/api, referer: http://domain.de/ckan/

I don't know who points to /api there? So, I just created an Apache alias like

 Alias /api /opt/ckan/pyenv/src/ckan/ckan

... assuming that this is the path to the API.

BTW: It doesn't matter if the Alias is active or not. In both cases the Upload link does not appear.

So, I assume that Apache does not have the right path to the API. The only Apache config so far is

WSGIScriptAlias /ckan /opt/ckan/pyenv/src/ckan/bin/domain.de.py
WSGIPassAuthorization On

Cheers
Ralf
