=============
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
----------------------
.. code:: bash
$ pip install core_main_app
Manual installation
-------------------
.. code:: bash
$ 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:
.. code:: python
INSTALLED_APPS = [
...
"tz_detect",
"core_main_app",
]
Add the middleware required by ``tz_detect``:
.. code:: python
MIDDLEWARE = (
...
'tz_detect.middleware.TimezoneMiddleware',
)
Edit the urls.py file
---------------------
Add the ``core_main_app`` urls to the Django project as such.
.. code:: python
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.
.. code:: bash
$ python manage.py compilemessages
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.
.. code:: bash
$ 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.
.. code:: python
BROKER_URL = 'redis://:<password>@localhost:6379/0'
CELERY_RESULT_BACKEND = 'redis://:<password>@localhost:6379/0'
Enable SMTP server
------------------
Please follow these steps to configure the SMTP server:
* Set these constants in your setting.py file (all these constants are required)
.. code:: py
EMAIL_HOST = 'smtp.myserver.com'
EMAIL_PORT = 587
DEFAULT_FROM_EMAIL = 'TestSite Team <noreply@example.com>'
* These optional constants can be added in your setting.py according to your SMTP server configuration
.. code:: py
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'testsite_app'
EMAIL_HOST_PASSWORD = 'mys3cr3tp4ssw0rd'
Enable History
--------------
Django Simple History allows keeping track of changes made to an object stored in the CDCS database.
First, install and configure the package. See the
`django-simple-history <https://django-simple-history.readthedocs.io/en/latest/quick_start.html>`_ documentation.
Then, set the `DJANGO_SIMPLE_HISTORY_MODELS` setting with a list of models to track.
At the moment, this feature is only available for the `Data` model.
.. code:: python
DJANGO_SIMPLE_HISTORY_MODELS=["Data"]
Register models to track by updating project files.
For example in ``mdcs/mdcs_home/admin.py``, add the following lines:
.. code:: python
from core_main_app.utils.admin_site.model_admin_class import register_simple_history_models
from django.conf import settings
DJANGO_SIMPLE_HISTORY_MODELS = getattr(settings, "DJANGO_SIMPLE_HISTORY_MODELS", None)
register_simple_history_models(DJANGO_SIMPLE_HISTORY_MODELS)
Documentation
=============
Documentation has been generated using Sphinx. To generate a local version of
the docs, please clone the repository and run:
.. code:: bash
$ cd docs/
$ make html
Or, directly using Sphinx:
.. code:: bash
$ cd docs/
$ sphinx-build -b html . ../dist/_docs
Development
===========
Development version
-------------------
A development version of this package is available, containing tests and formatting
dependencies. To automatically install the development version, run:
.. code:: bash
$ pip install .[develop]
The development dependencies are located in ``requirements.dev.txt`` and can be installed
manually using:
.. code:: bash
$ pip install -r requirements.dev.txt
Code formatting
---------------
To ensure consistent formatting across the codebase, the development team is using
`black <https://github.com/psf/black>`_. When contributing to this package, install black
as part of the development packages and run ``black /path/to/core_main_app`` before
submitting the contribution.
Tests
-----
To play the test suite created for this package, download the git repository, install the
development dependencies and run:
.. code:: bash
$ python runtests.py
Sending email
-------------
To test the email being sent, console backend will print the email instead of sending the real email.
By default, the console backend writes to stdout
To specify this backend, add the following in your settings:
.. code:: python
EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'
