Installation

For example installing any non-Python dependencies or adding any required config settings.

To install ckanext-plotly:

  1. Activate your CKAN virtual environment, for example:

    . /usr/lib/ckan/default/bin/activate

  2. Clone the source and install it on the virtualenv

    git clone https://github.com/USEPA/ckanext-plotly.git cd ckanext-plotly pip install -e . pip install -r requirements.txt

None at present

Developer installation

To install ckanext-plotly for development, activate your CKAN virtualenv and do:

git clone https://github.com/USEPA/ckanext-plotly.git
cd ckanext-plotly
python setup.py develop
pip install -r dev-requirements.txt

Rebuilding the editor/explorer

The editor/explorer is built off of react-chart-editor. At present this being react based application necessitates some effort to export for use as a CKAN javascript asset. To accomplish this the following manual process is has been employed. A customized build process would be a great addition!

  1. Build the editor interface via npm:

    cd ckanext-plotly/editor_app/src
npm run build

  2. Copy the built js and css bundles over to the CKAN location

    cp ../build/static/css/main*.css ../../ckanext/plotly/public/plotly_edit_app.css
cp ../build/static/css/main*.css.map ../../ckanext/plotly/public/plotly_edit_app.css.map
cp ../build/static/js/main*.js ../../ckanext/plotly/public/plotly_edit_app.js
cp ../build/static/js/main*.js.map ../../ckanext/plotly/public/plotly_edit_app.js.map

  3. Edit the source map in the final line in plotly_edit_app.css and plotly_edit_app.js.map to point to the appropriate map file

Tests

To run the tests, do:

pytest --ckan-ini=test.ini ckanext
