CI/CD Pipeline

Submit social housing lettings and sales data (CORE)

This is the codebase for the Ruby on Rails app that will handle the submission of lettings and sales of social housing data in England.

API documentation

API documentation can be found here: https://communitiesuk.github.io/mhclg-data-collection-beta/. This is driven by OpenAPI docs

Required Setup

Pre-requisites:

  • Ruby
  • Rails
  • Postgres

Quick start

  1. Copy the .env.example to .env and replace the database credentials with your local postgres user credentials.

  2. Install the dependencies:
    bundle install

  3. Create the database:
    rake db:create

  4. Run the database migrations:
    rake db:migrate

  5. Install the frontend depenencies:
    yarn install

  6. Start the Rails server:
    bundle exec rails s

The Rails server will start on http://localhost:3000.

Using Docker

docker-compose build
docker-compose run --rm app rails db:create
docker-compose up

The Rails server will start on http://localhost:8080.

Note docker-compose runs the production docker image (RAILS_ENV=production) as the Dockerfile doesn’t include development gems to keep the image size down.

Infrastructure

This application is running on GOV.UK PaaS. To deploy you need to:

  1. Contact your organisation manager to get an account in dluhc-core organization and in the relevant spaces (staging/production).

  2. Install the Cloud Foundry CLI

  3. Login:
    cf login -a api.london.cloud.service.gov.uk -u <your_username>

  4. Set your deployment target (staging/production):
    cf target -o dluhc-core -s <deploy_environment>

  5. Deploy:
    cf push dluhc-core --strategy rolling. This will use the manifest file

Once the app is deployed:

  1. Get a Rails console:
    cf ssh dluhc-core-staging -t -c "/tmp/lifecycle/launcher /home/vcap/app 'rails console' ''"

  2. Check logs:
    cf logs dluhc-core-staging --recent

Troubleshooting deployments

A failed Github deployment action will occasionally leave a Cloud Foundry deployment in a broken state. As a result all subsequent Github deployment actions will also fail with the message Cannot update this process while a deployment is in flight.

cf cancel-deployment dluhc-core

You'd then need to check the logs and fix the issue that caused the initial deployment to fail.

CI/CD

When a commit is made to main the following GitHub action jobs are triggered:

  1. Test: RSpec runs our test suite
  2. Deploy: If the Test stage passes, this job will deploy the app to our GOV.UK PaaS account using the Cloud Foundry CLI

When a pull request is opened to main only the Test stage runs.

Single log submission

The form for this is driven by a JSON file in /config/forms/{start_year}_{end_year}.json

The JSON should follow the structure:

{
  "form_type": "lettings" / "sales",
  "start_year": Integer, // i.e. 2020
  "end_year": Integer, // i.e. 2021
  "sections": {
    "[snake_case_section_name_string]": {
      "label": String,
      "subsections": {
        "[snake_case_subsection_name_string]": {
          "label": String,
          "pages": {
            "[snake_case_page_name_string]": {
              "header": String,
              "description": String,
              "questions": {
                "[snake_case_question_name_string]": {
                  "header": String,
                  "hint_text": String,
                  "check_answer_label": String,
                  "type": "text" / "numeric" / "radio" / "checkbox" / "date",
                  "min": Integer, // numeric only
                  "max": Integer, // numeric only
                  "step": Integer, // numeric only
                  "width": 2 / 3 / 4 / 5 / 10 / 20, // text and numeric only
                  "prefix": String, // numeric only
                  "suffix": String, //numeric only
                  "answer_options": { // checkbox and radio only
                    "0": String,
                    "1": String
                  },
                  "conditional_for": {
                    "[snake_case_question_to_enable_1_name_string]": ["condition-that-enables"],
                    "[snake_case_question_to_enable_2_name_string]": ["condition-that-enables"]
                  },
                  "inferred_answers": { "field_that_gets_inferred_from_current_field": { "is_that_field_inferred": true } },
                  "inferred_check_answers_value": {
                    "condition": { "field_name_for_inferred_check_answers_condition": "field_value_for_inferred_check_answers_condition" },
                    "value": "Inferred value that gets displayed if condition is met"
                  }
                }
              },
              "depends_on": [{ "question_key": "answer_value_required_for_this_page_to_be_shown" }]
            }
          }
        }
      }
    }
  }
}

Assumptions made by the format:

  • All forms have at least 1 section

  • All sections have at least 1 subsection

  • All subsections have at least 1 page

  • All pages have at least 1 question

  • The ActiveRecord case log model has a field for each question name (must match). In the case of checkbox questions it must have one field for every answer option (again names must match).

  • Text not required by a page/question such as a header or hint text should be passed as an empty string

  • For conditionally shown questions, conditions that have been implemented and can be used are:

    • Radio question answer option selected matches one of conditional e.g. ["answer-options-1-string", "answer-option-3-string"]
    • Numeric question value matches condition e.g. [">2"], ["<7"] or ["== 6"]
  • When the top level question is a radio button and the conditional question is a numeric, text or date field then the conditional question is shown inline

  • When the conditional question is a radio, checkbox or select field it should be displayed on it's own page and "depends_on" should be used rather than "conditional_for"

    Page routing:

    • Form navigation works by stepping sequentially through every page defined in the JSON form definition for the given subsection. For every page it checks if it has "depends_on" conditions. If it does, it evaluates them to determine whether that page should be show or not.

    • In this way we can build up whole branches by having:

    "page_1": { "questions": { "question_1: "answer_options": ["A", "B"] } },
    "page_2": { "questions": { "question_2: "answer_options": ["C", "D"] }, "depends_on": [{ "question_1": "A" }] },
    "page_3": { "questions": { "question_3: "answer_options": ["E", "F"] }, "depends_on": [{ "question_1": "A" }] },
    "page_4": { "questions": { "question_4: "answer_options": ["G", "H"] }, "depends_on": [{ "question_1": "B" }] },
    

JSON Form Validation against Schema

To validate the form JSON against the schema you can run: rake form_definition:validate["config/forms/2021_2022.json"]

n.b. You may have to escape square brackets in zsh rake form_definition:validate\["config/forms/2021_2022.json"\]

This will validate the given form definition against the schema in config/forms/schema/generic.json.

You can also run: rake form_definition:validate_all This will validate all forms in directories = ["config/forms", "spec/fixtures/forms"]
