The Observatory Control System (OCS) Observation Portal django apps

Observation Portal

An API for Astronomical Observation Management

Within an observatory control system, the observation portal provides modules for:

• Proposal management: Calls for proposals, proposal creation, and time allocation
• Request management: Observation request validation, submission, and cancellation, as well as views providing ancillary information about them
• Observation management: Store and provide the telescope schedule, update observations, and update observation requests on observation update
• User identity management: Oauth2 authenticated user management that can be used in other applications

Prerequisites

Optional prerequisites can be skipped for reduced functionality.

• Python >= 3.7
• PostgreSQL >= 9.6
• A running Configuration Database
• (Optional) A running Downtime Database
• (Optional) A running Elasticsearch

Environment Variables

	Variable	Description	Default
General	DEBUG	Whether the application should run using Django's debug mode	False
	SECRET_KEY	The secret key used for sessions	random characters
	ALLOWED_HOSTS	Override for Django's ALLOWED_HOSTS setting	*
	CSRF_TRUSTED_ORIGINS	Comma separated list of trusted origins allowed for CSRF	None
	MAX_FAILURES_PER_REQUEST	Maximum number of times an Observation can fail per Request before the Request is marked as FAILURE_LIMIT_REACHED. 0 means there is no max.	0

	PROPOSAL_TIME_OVERUSE_ALLOWANCE	The amount of leeway in a proposals timeallocation before rejecting that request for scheduling. For example, a value of 1.1 results in allows over-scheduling by up to 10% of the total time_allocation. It is useful to allow some over-scheduling since it is likely some in progress observations will use less time then allocated, due to conservative overheads, failing, or cancelling.	1.1

Local Development

Set up external services

Please refer to the Configuration Database and Downtime Database projects for instructions on how to get those running, as well as the Elasticsearch documentation for options on how to run Elasticsearch.

Set up a virtual environment

Using a virtual environment is highly recommended. Run the following commands from the base of this project. (env) is used to denote commands that should be run using your virtual environment.

python3 -m venv env
source env/bin/activate
(env) pip install numpy && pip install -e .[test]

Set up the database

This example uses the PostgreSQL Docker image to create a database. Make sure that the options that you use to set up your database correspond with your configured database settings.

docker run --name observation-portal-postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=observation_portal -v/var/lib/postgresql/data -p5432:5432 -d postgres:11.1

After creating the database, migrations must be applied to set up the tables in the database.

(env) python manage.py migrate

Run the tests

(env) python manage.py test --settings=observation_portal.test_settings

Run the portal

(env) python manage.py runserver

The observation portal should now be accessible from http://127.0.0.1:8000!
