+ckanext-ga-report
+=================
 
+**Status:** Development
+
+**CKAN Version:** 1.7.1+
+
+
+Overview
+--------
+
+For creating detailed reports of CKAN analytics, including totals per group.
+
+Whereas ckanext-googleanalytics focusses on providing page view stats a recent period and for all time (aimed at end users), ckanext-ga-report is more interested in building regular periodic reports (more for site managers to monitor).
+
+Contents of this extension:
+
+ * Use the CLI tool to download Google Analytics data for each time period into this extension's database tables
+
+ * Users can view the data as web page reports
+
+
+Installation
+------------
+
+1. Activate you CKAN python environment and install this extension's software::
+
+    $ pyenv/bin/activate
+    $ pip install -e  git+https://github.com/datagovuk/ckanext-ga-report.git#egg=ckanext-ga-report
+
+2. Ensure you development.ini (or similar) contains the info about your Google Analytics account and configuration::
+
+      googleanalytics.id = UA-1010101-1
+      googleanalytics.account = Account name (e.g. data.gov.uk, see top level item at https://www.google.com/analytics)
+      googleanalytics.token.filepath = ~/pyenv/token.dat
+      ga-report.period = monthly
+      ga-report.bounce_url = /
+
+   The ga-report.bounce_url specifies a particular path to record the bounce rate for. Typically it is / (the home page).
+
+3. Set up this extension's database tables using a paster command. (Ensure your CKAN pyenv is still activated, run the command from ``src/ckanext-ga-report``, alter the ``--config`` option to point to your site config file)::
+
+    $ paster initdb --config=../ckan/development.ini
+
+4. Enable the extension in your CKAN config file by adding it to ``ckan.plugins``::
+
+    ckan.plugins = ga-report
+
+Problem shooting
+----------------
+
+* ``(ProgrammingError) relation "ga_url" does not exist``
+  This means that the ``paster initdb`` step has not been run successfully. Refer to the installation instructions for this extension.
+
+
+Authorization
+--------------
+
+Before you can access the data, you need to set up the OAUTH details which you can do by following the `instructions <https://developers.google.com/analytics/resources/tutorials/hello-analytics-api>`_ the outcome of which will be a file called credentials.json which should look like credentials.json.template with the relevant fields completed. 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 `Services pane <https://code.google.com/apis/console#:services>`_ , activate Analytics API for your project. If prompted, read and accept the terms of service.
+
+4. Go to the `API Access pane <https://code.google.com/apis/console/#:access>`_
+
+5. Click Create an OAuth 2.0 client ID....
+
+6. Fill out the Branding Information fields and click Next.
+
+7. In Client ID Settings, set Application type to Installed application.
+
+8. Click Create client ID
+
+9. The details you need below are Client ID, Client secret, and  Redirect URIs
+
+
+Once you have set up your credentials.json file you can generate an oauth token file by using the
+following command, which will store your oauth token in a file called token.dat once you have finished
+giving permission in the browser::
+
+    $ paster getauthtoken --config=../ckan/development.ini
+
+Now ensure you reference the correct path to your token.dat in your CKAN config file (e.g. development.ini)::
+
+    googleanalytics.token.filepath = ~/pyenv/token.dat
+
+
+Tutorial
+--------
+
+Download some GA data and store it in CKAN's database. (Ensure your CKAN pyenv is still activated, run the command from ``src/ckanext-ga-report``, alter the ``--config`` option to point to your site config file) and specifying the name of your auth file (token.dat by default) from the previous step::
+
+    $ paster loadanalytics latest --config=../ckan/development.ini
+
+The value after the token file is how much data you want to retrieve, this can be
+
+* **all**         - data for all time (since 2010)
+
+* **latest**      - (default) just the 'latest' data
+
+* **YYYY-MM-DD**  - just data for all time periods going back to (and including) this date
