Data Submission Service API

An API layer that manages and exposes data on CCS frameworks. This service ingests submissions and create invoices for business done each month against each active framework.

Admin users are able to use this tool to create new users and associate them with suppliers. These users will then be able to use the frontend application to submit their information.

Various parts of the system are documented in /docs and also as part of the Service Manual for the service.


  • Docker greater than or equal to 18.03.1-ce-mac64 (24245)
  • Access to the dxw 1Password vault named DSS can be granted by anyone on the dxw technical operations team

Setting up the project

Copy the example environment variable file used with Docker:

$ cp docker-compose.env.sample docker-compose.env

From the 1Password vault, copy the contents of a file named Docker Compose - API - docker-compose.env into the new docker-compose.env file. This file should contain no further additions to get started.

The most common command used to start all containers. It does database set up if required and leaves you on an interactive prompt within the rails server process where pry can be used for debugging:

$ bin/dstart

If you'd like to see all logs, like Sidekiq or Redis you can use the conventional docker-compose command - you will lose the ability to use pry:

$ docker-compose --env-file docker-compose.env up --build

If you'd like to shut all containers down, and remove database information persisted in docker volumes you can run the following command which rebuilds everything from scratch:

$ bin/drebuild

Running the tests

Because the setup and teardown introduces quite some latency, we use the spring service to start up all dependencies in a docker container. This makes the test run faster.

Get the test server up and running behind the scenes:

$ bin/dtest-server up

Run all the RSpec tests:

$ bin/dspec spec

When no arguments are specified, the default rake task is executed. This runs other tests such as Rubocop for linting and brakeman for static code analysis.

You can use pass arguments as you normally would to RSpec through this script, to run a single test for example you can use bin/dspec spec/features/adding_a_user_spec.rb:1

To stop the test server from running in the background:

$ bin/dtest-server down

Managing gems

When making changes to the Gemfile we should use Docker too in order to ensure we use a consistent version of Bundler:

$ docker-compose run --rm web bundle

The Bundler version in the Gemfile.lock should remain unchanged unless part of a deliberate update.


The admin interface

The admin interface is available at /admin. In production its use requires OAuth authentication via a Google provider, but there is a DeveloperAdmin provider which will let you log in locally to develop admin functions without credentials. You should not need to do anything to set this up; it will apply by default if either of GOOGLE_CLIENT_ID or GOOGLE_CLIENT_SECRET are missing from your development environment.

It will use the ADMIN_EMAILS variable from docker-compose.env by default with a default user full name, either of which can be changed at login if you wish.

API Endpoints

A full list of the API endpoints is available in SwaggerHub.

Onboarding suppliers and users

See this guide for details on onboarding suppliers and their users.

Scheduled jobs

Job scheduling is handled using the sidekiq-cron gem, with the schedule defined in config/sidekiq_schedule.yml.

Generating monthly tasks

The monthly tasks for suppliers are generated on the 1st of the month via the sidekiq schedule described above.

Reporting rake tasks

There are Rake tasks to report the status of monthly tasks:

  # Reports monthly task statistics. Defaults to the current month’s tasks.
  $ bin/drake report:submission_stats

  # Report spend and management charge. Defaults to the current month’s tasks.
  $ bin/drake report:spend_and_management_charge

Console helpers

There are some handy methods available in the Rails console for debugging submissions and reporting on the state of the monthly tasks. See lib/console_helpers.rb for more details.


Documentation on how deployments are managed for the RMI service as a whole are documented within the service manual.
