[ckan-dev] Virtualenv tips: how to reload the ini file

[Nigel Babu]

Hi John,

I'm not sure what you're trying to do here. Why is there an existing python
process? If you're running CKAN development server with paster, you should kill
your existing sessions before disconnecting or run it over screen/tmux. If
you're not using screen/tmux, it should be killed automatically anyway.

What paster serve --reload does is reload the CKAN configuration and code if
any of the code or configuration changes. Though, I have to warn you, it
doesn't recognize new files. Template changes will not be re-loaded, because it
doesn't need to be.
