This CKAN extension allows a user to create private datasets that only certain users will be able to see. When a dataset is being created, it's possible to specify the list of users that can see this dataset. In addition, the extension provides an HTTP API that allows to add users programatically.
Installation
------------
Install this extension in your CKAN is instance is as easy as intall any other CKAN extension.
* Download the source from this GitHub repo.
* Activate your virtual environment (generally by running `. /usr/lib/ckan/default/bin/activate`)
* Install the extension by running `python setup.py develop`
* Modify your configuration file (generally in `/etc/ckan/default/production.ini`) and add `privatedatasets` in the `ckan.plugins` setting.
* In the same config file, specify the location of your parser by adding the `ckan.privatedatasets.parser` setting. For example, to set the [FiWareNotificationParser](https://github.com/conwetlab/ckanext-privatedatasets/blob/master/ckanext/privatedatasets/parsers/fiware.py) as notification parser, add the following line: `ckan.privatedatasets.parser = ckanext.privatedatasets.parsers.fiware:FiWareNotificationParser`.
* If you want you can also add some preferences to set if the Acquire URL should be shown when the user is creating and/or editing a dataset:
* To show the Acquire URL when the user is **creating** a dataset, you should set the following preference: `ckan.privatedatasets.show_acquire_url_on_create = True`. By default, the value of this preference is set to `False`.
* To show the Acquire URL when the user is **editing** a dataset, you should set the following preference: `ckan.privatedatasets.show_acquire_url_on_edit = True`. By default, the value of this preference is set to `False`.
* Restart your apache2 reserver (`sudo service apache2 restart`)
* That's All!
Creating a notification parser
------------------------------
Since each service can send notifications in a different way, the extension allows developers to create their own notifications parser. As default, we provide you a basic parser based on the notifications sent by the [FiWare Store](https://github.com/conwetlab/wstore/).
If you want to create your own parser, you have to:
2. Parse the notification as you like. You can raise a CKAN's default exception (`ValidationError`, `ObjectNotFound`, `NotAuthorized`, `ValidationError`, `SearchError`, `SearchQueryError` or `SearchIndexError`) if you find an error parsing the notification.
3. Return a dictionary with the structure attached below. The `users_datasets` is the lists of datasets available for each user (each element of this list is a dictionary with two fields: `user` and `datasets`).
**Note:** The `test.ini` file contains a link to the CKAN `test-core.ini` file. You will need to change that link to the real path of the file in your system (generally `/usr/lib/ckan/default/src/ckan/test-core.ini`).
You can also generate coverage reports by running:
