CKAN extension for the Landcare Research Datastore

• ckanext-repeating

• ckanext-ldap

1. Activate your virtualenv, eg:

    source /usr/lib/ckan/default/bin/activate
   

2. Install ckanext-repeating:

    cd /usr/lib/ckan/default/src
    git clone https://github.com/open-data/ckanext-repeating.git
    cd ckanext-repeating
    python setup.py develop
   

3. Install ckanext-ldap:

    # Install required libraries
    apt-get install libldap2-dev libsasl2-dev libssl-dev
   
    cd /usr/lib/ckan/default/src
    git clone https://github.com/okfn/ckanext-ldap.git
    cd ckanext-ldap
    pip install -r requirements.txt
    python setup.py develop
   

4. Install ckanext-lcrnz:

    cd /usr/lib/ckan/default/src
    git clone https://github.com/okfn/ckanext-lcrnz.git
    cd ckanext-lcrnz
    python setup.py develop
   

5. Update the necessary settings in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini):

    # ...
   
    ckan.plugins = repeating lcrnz ldap
   
   
    # LDAP settings (adjust uri to the actual one)
    ckanext.ldap.uri = ldap://localhost:389
    ckanext.ldap.base_dn = ou=users,dc=landcareresearch,dc=co,dc=nz
    ckanext.ldap.search.filter = uid={login}
    ckanext.ldap.username = uid
    ckanext.ldap.email = mail
    ckanext.ldap.fullname = cn
   
    # This is the id of the Landcare Research CKAN organization
    # You can get it from http://datastore.landcareresearch.co.nz/api/action/organization_show?id=landcare-research
    ckanext.ldap.organization.id = cfa490ed-d9e4-46a6-8c43-a7057cfebd1c
    ckanext.ldap.organization.role = member
   
   
    # Custom i18n folder (for replacing "organizations" with "collections")
    # Update the path if necessary
    ckan.locale_default = en_NZ
    ckan.i18n_directory = /usr/lib/ckan/default/src/ckanext-lcrnz
   

   The rest of standard settings (site_id, solr_url, ...) are not covered here but should of course be set up as well.

To test the LDAP integration on a development enviroment there is a Docker image preloaded with a test directory that you can run:

1. Install docker

2. Run:

    docker run --name ldap -p 389:389 -d openknowledge/openldap-lcrnz
   

For more details check https://github.com/okfn/docker-openldap-lcrnz

The extension ships with customized translation files that replace occurrences of "organization" with "collection". These are located in the i18n folder and require the ckan.i18n_directory and ckan.locale_default settings to be set up (see above).

If it is necessary to modify the translation strings, follow these steps:

1. Install Babel if necessary (make sure to have your virtualenv activated):

   pip install babel

2. Modify the ckanext-lcrnz/i18n/en_NZ/LC_MESSAGES/ckan.po file. You must only change the msgstr sections.

3. Compile a new ckan.mo file with the following command (make sure to have your virtualenv activated):

    python setup.py compile_catalog -D ckan -d i18n
   

4. Restart the web server
