gitphp 0.2.9.1 :: ckanext-ga-report.git/commitdiff

Packages up the data from Analytics.

- Makes sure we get the right account by requiring a new googleanalytics.account
config option which will be used to look up the correct account details.

- Changed the model to use the sqlalchemy orm and made sure it does the updates correctly.

- Still need to collect further info (such as the group details)
