# CKAN Google Analytics Extension
|
|
|
|
**Status:** Production
|
|
|
|
**CKAN Version:** >= 2.8
|
|
|
|
A CKAN extension that both sends tracking data to Google Analytics and
|
|
retrieves statistics from Google Analytics and inserts them into CKAN pages.
|
|
|
|
## Features
|
|
|
|
|
|
* Puts the Google Analytics asynchronous tracking code into your page headers
|
|
for basic Google Analytics page tracking.
|
|
|
|
* Adds Google Analytics Event Tracking to resource download links, so that
|
|
resource downloads will be displayed as Events in the Google Analytics
|
|
reporting interface.
|
|
|
|
* Adds Google Analytics Event Tracking to some API calls so that usage of the
|
|
API can be reported on via Google Analytics.
|
|
|
|
* Add Google Analytics Event Tracking function that can be used in any exstension
|
|
to create your custom events tracking.

ckanext.googleanalytics.plugin._post_analytics
|
|
|
|
## Installation
|
|
|
|
|
|
1. Install the extension as usual, e.g. (from an activated virtualenv):
|
|
|
|
$ pip install -e git+https://github.com/ckan/ckanext-googleanalytics.git#egg=ckanext-googleanalytics
|
|
$ pip install -r ckanext-googleanalytics/requirements.txt
|
|
|
|
2. Edit your development.ini (or similar) to provide these necessary parameters:
|
|
|
|
googleanalytics.id = UA-1010101-1
|
|
googleanalytics.account = Account name (i.e. data.gov.uk, see top level item at https://www.google.com/analytics)
|
|
googleanalytics.username = googleaccount@gmail.com
|
|
googleanalytics.password = googlepassword
|
|
|
|
Note that your password will probably be readable by other people;
|
|
so you may want to set up a new gmail account specifically for
|
|
accessing your gmail profile.
|
|
|
|
3. Edit again your configuration ini file to activate the plugin
|
|
with:
|
|
|
|
ckan.plugins = googleanalytics
|
|
|
|
(If there are other plugins activated, add this to the list. Each
|
|
plugin should be separated with a space).
|
|
|
|
4. Finally, there are some optional configuration settings (shown here
|
|
with their default settings)
|
|
|
|
googleanalytics_resource_prefix = /downloads/
|
|
googleanalytics.domain = auto
|
|
googleanalytics.fields = {}
|
|
googleanalytics.enable_user_id = false
|
|
googleanalytics.download_handler = ckan.views.resource:download
|
|
|
|
``resource_prefix`` is an arbitrary identifier so that we can query
|
|
for downloads in Google Analytics. It can theoretically be any
|
|
string, but should ideally resemble a URL path segment, to make
|
|
filtering for all resources easier in the Google Analytics web
|
|
interface.
|
|
|
|
``domain`` allows you to specify a domain against which Analytics
|
|
will track users. You will usually want to leave this as ``auto``;
|
|
if you are tracking users from multiple subdomains, you might want
|
|
to specify something like ``.mydomain.com``.
|
|
See `Google's documentation
|
|
<http://code.google.com/apis/analytics/docs/gaJS/gaJSApiDomainDirectory.html#_gat.GA_Tracker_._setDomainName>`_
|
|
for more info.
|
|
|
|
``fields`` allows you to specify various options when creating the tracker. See `Google's documentation <https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference>`.
|
|
|
|
If ``enable_user_id`` is set to ``true``, then logged in users will be tracked into the Google Analytics' dashboard.
|
|
This way metrics can be tracked for every logged in user. You can read more
|
|
about this feature and its benefits `here <https://support.google.com/analytics/answer/3123662>`_.
|
|
|
|
When resource is downloaded, ckanext-googleanalytics posts event to
|
|
GA and calls default download callback. If you are using CKAN>=2.9
|
|
and some of your plugins redefines `resource.download`
|
|
route(ckanext-cloudstorage, for example), you can specify which
|
|
function must be called instead of `ckan.views.resource:download`
|
|
via `ckanext.googleanalytics.download_handler` config variable. For ckanext-cloudstorage you can use:
|
|
|
|
googleanalytics.download_handler = ckanext.cloudstorage.views:download
|
|
|
|
# Domain Linking
|
|
|
|
|
|
This plugin supports cross-domain tracking using Googles' site linking feature.
|
|
|
|
To use this, set the ``googleanalytics.linked_domains`` configuration option to a (comma seperated) list of domains to report for.
|
|
|
|
See `Googles' documentation<https://support.google.com/analytics/answer/1034342?hl=en>`_ for more information
|
|

|
# Setting Up Statistics Retrieval from Google Analytics
|
|
|
|
|
|
1. Run the following command from ``src/ckanext-googleanalytics`` to
|
|
set up the required database tables (of course, altering the
|
|
``--config`` option to point to your site config file):
|
|
|
|
ckan -c ../ckan/ckan.ini initdb
|
|
|
|
3. Follow the steps in the *Authorization* section below.
|
|
|
|
4. Restart CKAN (e.g. by restarting Apache)
|
|
|
|
5. Wait a while for some stats to be recorded in Google
|
|
|
|
6. Import Google stats by running the following command from
|
|
``src/ckanext-googleanalytics``::
|
|
|
|
paster loadanalytics credentials.json --config=../ckan/development.ini
|
|
|
|
(Of course, pointing config at your specific site config and credentials.json at the
|
|
key file obtained from the authorization step)
|
|
Ignore warning `ImportError: file_cache is unavailable when using oauth2client >= 4.0.0`
|
|
|
|
7. Look at some stats within CKAN
|
|
|
|
Once your GA account has gathered some data, you can see some basic
|
|
information about the most popular packages at:
|
|
http://mydomain.com/analytics/dataset/top
|
|
|
|
By default the only data that is injected into the public-facing
|
|
website is on the package page, where number of downloads are
|
|
displayed next to each resource.
|
|
|
|
8. Consider running the import command reguarly as a cron job, or
|
|
remember to run it by hand, or your statistics won't get updated.
|
|
|
|
|
|
## Authorization
|
|
|
|
|
|
Before ckanext-googleanalytics can retrieve statistics from Google Analytics, you need to set up the OAUTH details which you can do by following the `instructions <https://developers.google.com/analytics/devguides/reporting/core/v3/quickstart/service-py>`_ the outcome of which will be a file with authentication key. These steps are below for convenience:
|
|
|
|
1. Visit the `Google APIs Console <https://code.google.com/apis/console>`_
|
|
|
|
2. Sign-in and create a project or use an existing project.
|
|
|
|
3. In the `Service accounts pane <https://console.developers.google.com/iam-admin/serviceaccounts>`_ choose your project and create new account. During creation check "Furnish a new private key" -> JSON type. Write down "Service account ID"(looks like email) - it will be used later.
|
|
|
|
4. Save downloaded file - it will be used by `loadanalytics` command(referenced as <credentials.json>)
|
|
|
|
5. Go to `GoogleAnalytics console <https://analytics.google.com/analytics/web/#management>`_ and chose ADMIN tab.
|
|
|
|
6. Find "User management" button in corresponding column. Add service account using Service account ID(email) generated in 3rd step and grant "Read" role to it.
|
|
|
|
|
|
## Testing
|
|
|
|
|
|
There are some very high-level functional tests that you can run using::
|
|
|
|
$ pip install -r dev-requirements.txt
|
|
$ pytest --ckan-ini=test.ini
|
|
|
|
|
|
## Future
|
|
|
|
This is a bare-bones, first release of the software. There are
|
|
several directions it could take in the future.
|
|
|
|
Because we use Google Analytics for recording statistics, we can hook
|
|
into any of its features. For example, as a measure of popularity, we
|
|
could record bounce rate, or new visits only; we could also display
|
|
which datasets are popular where, or highlight packages that have been
|
|
linked to from other locations.
|
|
|
|
We could also embed extra metadata information in tracking links, to
|
|
enable reports on particular types of data (e.g. most popular data
|
|
format by country of origin, or most downloaded resource by license)
