[ckan-dev] DataStorer extension location question

Wed Jun 13 15:53:31 UTC 2012

Hi Jim,

Sorry to hear that you are having trouble with the datastorer. Trust
me, it definitely works on different projects :)

I've improved the install instructions on the README [1], which I
agree could be confusing, so I suggest we start all over again.

1. Remove any datastorer folder that you have right now
2. Activate your virtualenv
3. Run pip install -e
git+git://github.com/okfn/ckanext-datastorer.git#egg=ckanext-datastorer
4. Run pip install -r ckanext-datastorer/requires.txt

At this point you should have a ~/pyenv/src/ckanext-datastorer folder
and running this command should not return any errors or prompts:

python -c "import ckanext.datastorer"

After this point you need to add this to your ini file:

ckan.plugins = datastorer <rest of plugins>...

Let me know if this works for you.

Adrià
