• $CONFIG_FILE, e.g. /etc/ckan/default/development.ini

1. Clone the repository into the src folder:

cd $INSTALL_FOLDER/src
git clone https://github.com/NaturalHistoryMuseum/ckanext-statistics.git

2. Activate the virtual env:

. $INSTALL_FOLDER/bin/activate

3. Install the requirements from requirements.txt:

Usage

Actions

download_statistics

Statistics for downloads of datasets from the instance.

from ckan.plugins import toolkit

# all of these filters are optional
data_dict = {
                'resource_id': RESOURCE_ID,
                'year': YEAR,
                'month': MONTH
            }

toolkit.get_action('download_statistics')(
    context,
    data_dict
)

dataset_statistics

Statistics for dataset records.

from ckan.plugins import toolkit

# these filters are optional
data_dict = {
                'resource_id': RESOURCE_ID,
            }

toolkit.get_action('dataset_statistics')(
    context,
    data_dict
)

Commands

statistics

1. initdb: initialise the database model

    ckan -c $CONFIG_FILE statistics initdb
   

2. gbif: retrieve download statistics from GBIF.

   ckan -c $CONFIG_FILE statistics gbif
   

Testing

Test coverage is currently extremely limited.

To run the tests in this extension, there is a Docker compose configuration available in this repository to make it easy.

To run the tests against ckan 2.9.x on Python3:

1. Build the required images

docker-compose build

2. Then run the tests. The root of the repository is mounted into the ckan container as a volume by the Docker compose configuration, so you should only need to rebuild the ckan image if you change the extension's dependencies.

docker-compose run ckan

The ckan image uses the Dockerfile in the docker/ folder which is based on openknowledge/ckan-dev:2.9.
