HI,
The linux administrators advised that ckan is started by the following command:
systemctl start httpd
and stopped by
systemctl stop httpd.
And said I may run into trouble using:
. /usr/lib/ckan/default/bin/activate
cd /usr/lib/ckan/default/src/ckan
paster serve /etc/ckan/default/production.ini
I looked at activate and it does set environment variables that aren’t set now.
Also I updated the contents of (the theme we created) /usr/local/ckan/lib/default/src/ckanext-ntg_theme/requirements.txt to be the same as /usr/local/ckan/lib/default/src/ckan/requirements.txt. I was thinking it may be using that custom requirements.txt, but it made no difference.
So maybe it is not possible to run debug using a dns via apache?? Is that correct….????
Should it harm the apache startup if I just do this:
. /usr/lib/ckan/default/bin/activate
cd /usr/lib/ckan/default/src/ckan
paster serve /etc/ckan/default/production.ini
after I do a systemctl stop httpd.
Some more details that may help with diagnosis.
Log has this error(see highlighted section)

-rw-r--r--. 1 apache apache 7215 Jan 25 16:20 debughelpers.pyc
Perhaps the full debugToolbarExtension components weren’t installed.
I imagine this comes with the install by default.
Any advice would be appreciated.

Hi Judith,
To your original question, the home page is rendered using these templates:
https://github.com/ckan/ckan/blob/master/ckan/templates/home/index.html
https://github.com/ckan/ckan/blob/master/ckan/templates/home/layout1.html
Now, to run in development mode you first need to install the development requirements:
https://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html#importerror-no-module-named-flask-debugtoolbar
You might need to change the path to the requirements file, and make sure to activate the virtualenv like Sam mentioned.
The Flask Debug Toolbar was introduced in recent versions so the documentation that you mention (2.3.x) is clearly outdated. You can check the version CKAN is running looking at the `ckan/__init__.py` file or visiting http://ckansite/api/action/status_show
Hope this helps,
Adrià

Hello,
I’m not sure what’s the official way to do it, but in our environment the way to run CKAN in debug mode is to do it locally, on the server. So, I do it as follows:
1. Log on the server (remote desktop or Putty or whatever way you do it).
2. Stop Apache:
apachectl stop
3. Change parameters in the production.ini (or development.ini, if you use that) to something like:
debug = true
…
ckan.site_url = http://127.0.0.1:5000
4. Start locally with paster:
. /usr/lib/ckan/default/bin/activate
cd /usr/lib/ckan/default/src/ckan
paster serve /etc/ckan/default/production.ini
After this, the site can viewed locally on the server, opening a browser at http://127.0.0.1:5000/.
When you want to return “online”, do the opposite (first killing the paster process).
Again, I’m not sure if this is the normal way to do it, especially as our CKAN version is a bit of a mix. In this case I hope someone else on the list can provide the correct way. I would be interested to hear it as well…
Hope this helps,
Sam

Hi,
I changed to false and the home page fails to load.
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at root at localhost to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log.
Previous CKAN person has made a new theme for site and it appears that debug does not work with the theme??
Hmm any suggestions.

Hello,
Not much more than a novice myself, I found it useful to run CKAN indebug-mode (https://docs.ckan.org/en/2.8/maintaining/configuration.html?highlight=debug#debug) to see what templates are used in each view. See more in Customizing CKAN’s templates (https://docs.ckan.org/en/2.8/theming/templates.html).
Also, the description of CKAN code architecture can help: https://docs.ckan.org/en/2.8/contributing/architecture.html
Regards,
Sam

Hi,
Totally novice to CKAN.
Can someone explain how the home page is instigated in CKAN.
Thx
