edcontext

This project contains three pieces:

• A webapp for visualizing and understanding MCIEA survey data
• Tasks for processing and indexing raw survey data
• Experimental work to conduct survey samples via text message

This is a Rails project, deployed on Heroku.

Local development

Install Postgres and running first.

(MacOS, Optional), you can use Homebrew:

brew install postgres
brew services start postgresql

Linux:

Install postgres. Known working version is version 13

https://www.postgresql.org/download/

Once postgres is installed and running, install the required gems and then migrate the database.

bundle install
bundle exec rake db:create db:migrate db:seed

Install the javascript dependencies

yarn install

At this point you can run the app and login. There won't be any data yet though; keep reading!

The seed file populates the following tables

Name	Description
School	School ids are only unique to their district. More than one school has an id of 1
District	Districts and schools have attached slugs. We find search for these models by their slugs
SqmCategory	The legacy name here is Category. It still exits in the database. We wanted the freedom to make changes and still preserve the legacy site until the end of the engagement.
Measure	In the bar graph measures represent a single bar
SurveyItem	This table has an attribute prompt that is the question asked

SurveyItemResponses does not get populated at this stage.

Database

Postgres

Gems

Name	Description
puma	webserver
pg	postgres
sassc-rails	sass compiler
jquery-rails	legacy, allows use of jquery
jbuilder	legacy, build json objects
haml	legacy, write views in haml syntax
bootstrap	css framework
newrelic_rpm	legacy?, application monitoring
devise	authentication
omniauth	authentication
twilio-ruby	legacy, text messaging
activerecord-import	faster database imports

External APIs

None yet. Hoping to integrate with Powerschool and Aspen for school administrative data.

Javascript libraries

Esbuild is used as the javascript bundler. The javascript testing library is jest.

Loading Data

SurveyItemResponses is the most important table to understand. SurveyItemResponses is the data that will change year to year and makes up the majority of the database records. Roughly 500,000 SurveyItemResponses per year.

Some notes:

• The data loading task assumes that the CSV files live in the #{RAILS_ROOT}/data/survey_responses directory
• The data loading task is idempotent, i.e. it can be run multiple times without duplicating previously-ingested data

How to run the data loading task:

# locally
$ bundle exec rake data:load_survey_responses

# on heroku staging environment
$ heroku run:detached -a mciea-beta bundle exec rake data:load_survey_responses

# on heroku production environment
$ heroku run:detached -a mciea-dashboard bundle rake data:load_survey_responses

For convenience, you can use the following script for loading data on Heroku:

# on heroku staging environment
$ ./scripts/load_survey_responses_on_heroku beta

# on heroku production environment
$ ./scripts/load_survey_responses_on_heroku dashboard

Running tests

Prepare the test database.

bundle exec rake db:test:prepare

If you need to look at the rails console for the test environment

RAILS_ENV=test rails c

bundle exec rake

Run javascript tests

yarn test

Continuous Integration

Pushing commits to the main branch triggers auto-deployment to the staging environment. Use the ship-it script from the main branch when you're ready to deploy to staging

scripts/ship-it.sh

Deployments to production must be done through the Heroku web interface or via the Heroku command line

Running the development server

Start esbuild for dynamic compilation of javascript assets.

yarn build --watch

Start the puma web server
