[ckan-dev] Problem with new extension installation

Fri Dec 21 14:23:58 UTC 2012

We have tried another approach :

1. We created the extension from scratch using first :

(pyenv)$ paster create -t ckanext ckanext-datagovgr

2. we updated the extension files (setup.py , plugin.py , css & html ) ,
setting
    a. @setup.py |  entry point as :
datagovgr_customizations=ckanext.datagovgr:DATAGOVGRCustomizations
    b. @plugin.py | class name as : class
DATAGOVGRCustomizations(plugins.SingletonPlugin):

3. Installed the extension in the virtual environment
(pyenv)$ cd ckanext-datagovgr
(pyenv)$ python setup.py develop
(pyenv)$ python

>>> import ckanext.datagovgr

4. Updated development.ini plugins section

    ckan.plugins = stats  datagovgr_customizations

Now , when we start CKAN we take a different error :

File
"/home/ckan/pyenv/local/lib/python2.7/site-packages/distribute-0.6.24-py2.7.egg/pkg_resources.py",
line 1994, in load
    raise ImportError("%r has no %r attribute" % (entry,attr))
ImportError: <module 'ckanext.datagovgr' from
'/home/ckan/pyenv/src/ckanext-datagovgr/ckanext/datagovgr/__init__.pyc'>
has no 'DATAGOVGRCustomizations' attribute
