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

Installing from PyPI

pip install ckanext-contact

Installing from source

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 via pip:

   pip install $INSTALL_FOLDER/src/ckanext-contact

Installing in editable mode

Installing from a pyproject.toml in editable mode (i.e. pip install -e) requires setuptools>=64; however, CKAN 2.9 requires setuptools==44.1.0. See our CKAN fork for a version of v2.9 that uses an updated setuptools if this functionality is something you need.

Post-install setup

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

   ckan.plugins = ... contact

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

Configuration

These are the options that can be specified in your .ini config file.

ckanext.contact.mail_to	Email address to submit to	email_to

ckanext.contact.add_timestamp_to_subject	Whether to append a timestamp to the subject line	false

ckanext.contact.recaptcha_v3_secret	API secret for the reCAPTCHA service.	False (i.e. disabled)

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>

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

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

Testing

There is a Docker compose configuration available in this repository to make it easier to run tests. The ckan image uses the Dockerfile in the docker/ folder.

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
