Core Main App¶

This Django reusable app contains the main functionalities for the curator core project.

Pre-requisites¶

For automated and manual install, the following software are needed:

python
pip
virtual env (conda or venv)

In addition, for manual setup, git is needed.

Installation¶

Automated installation¶

$ pip install core_main_app

Manual installation¶

$ git clone https://github.com/usnistgov/core_main_app.git
$ cd core_main_app
$ python setup.py
$ pip install sdist/*.tar.gz

Configuration¶

Edit the setting.py file¶

Add the "core_main_app" and "tz_detect" under INSTALLED_APPS as such:

INSTALLED_APPS = [
    ...
    "tz_detect",
    "core_main_app",
]

Add the middleware required by tz_detect:

MIDDLEWARE = (
    ...
    'tz_detect.middleware.TimezoneMiddleware',
)

Edit the urls.py file¶

Add the core_main_app urls to the Django project as such.

url(r'^', include("core_main_app.urls")),

Internationalization (i18n)¶

Before running the project, don’t forget to compile the translation file at project level. i18n uses the gettext package, so please make sure it is installed prior to using this command.

$ python manage.py compilemessages

Tests¶

To play the test suite created for this package, download the git repository and run:

$ python runtests.py

Documentation¶

Documentation has been generated using Sphinx. To generate a local version of the docs, please clone the repository and run:

$ cd docs/
$ make html

Or, directly using Sphinx:

$ cd docs/
$ sphinx-build -b html . ../dist/_docs

Enable SSL connection¶

Please follow these steps to configure the connection to any system running over HTTPS (including the local instance).

Create a folder for SSL certificates,
Copy the certificate in the folder,
Run c_rehash on the folder (needs to be done every time a new certificate is added to the folder),
Update the SSL_CERTIFICATES_DIR setting to point to the SSL certificate folder previously created.

$ mkdir certs
$ cp cdcs.crt certs/
$ c_rehash certs/

Enable Redis Server authentication¶

Please follow these steps to enable authentication on the redis server. Depending on the way Redis is started on the machine, the method may differ.

You can follow instructions at https://redis.io/topics/security#authentication-feature to enable authentication: * Open the file redis.conf (e.g. /usr/local/etc/redis.conf), * Uncomment the authentication setting (# requirepass foobared), * It is recommended to replace the default password (foobared) by a strong and long password, * Restart the Redis Server.

You should then update the CDCS settings using a Redis connection URL with the password chosen in the previous steps.

BROKER_URL = 'redis://:<password>@localhost:6379/0'
CELERY_RESULT_BACKEND = 'redis://:<password>@localhost:6379/0'
