ckanext-contact

A CKAN extension for adding popup contact forms to pages.

Overview

Borrows much of the contact form code from ckanext-surrey.

An example can be seen on the Natural History Museum's Data Portal when clicking "Contact dataset curator."

This extension now includes Google's reCAPTCHA for preventing spam submissions.

Installation

Path variables used below:

• $INSTALL_FOLDER (i.e. where CKAN is installed), e.g. /usr/lib/ckan/default
• $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-contact.git

2. Activate the virtual env:

. $INSTALL_FOLDER/bin/activate

3. Install the requirements from requirements.txt:

cd $INSTALL_FOLDER/src/ckanext-contact
pip install -r requirements.txt

4. Run setup.py:

cd $INSTALL_FOLDER/src/ckanext-contact
python setup.py develop

5. Add 'contact' to the list of plugins in your $CONFIG_FILE:

ckan.plugins = ... contact

Configuration

There are no settings that must be provided in your .ini config file, but there are some options:

Email

Name	Description	Default
ckanext.contact.mail_to	Email address to submit to	email_to
ckanext.contact.recipient_name	Name of the recipient	ckan.site_title
ckanext.contact.subject	Email subject for the submitted form	'Contact/Question from visitor'
ckanext.contact.add_timestamp_to_subject	Whether to append a timestamp to the subject line	false

Recaptcha

Name	Description	Default
ckanext.contact.recaptcha_v3_key	API key for the reCAPTCHA service.	False (i.e. disabled)
ckanext.contact.recaptcha_v3_secret	API secret for the reCAPTCHA service.	False (i.e. disabled)
ckanext.contact.recaptcha_v3_action	data-module-action for the form/button

Further Setup

To use reCAPTCHA, you must register a site with the Google reCAPTCHA service and add your API key and secret in the configuration.

Usage

Add the following HTML where you want the contact button to appear:

{% set params = {...} %}

<a class="btn btn-primary" data-module="modal-contact" data-module-template="{{ h.get_contact_form_template_url(params) }}" href="{{ h.url_for('contact.form', **params) }}" title="{{ _('Contact') }}">
    <i class="fas fa-envelope"></i>{{ link_text if link_text else _('CONTACT BUTTON TEXT') }}
</a>

{% resource 'ckanext-contact/main' %}

Where params is a dict with three entries: package_id, resource_id, record_id (all of which are optional).

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
