# edcontext

This project contains three pieces:

- A webapp for visualizing and understanding 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

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

On linux, if you run into problems creating the postgres database, edit /etc/postgresql/13/main/pg_hba.conf. Change the connection method of IPv4 and IPv6 connections from `md5` to trust.

```
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
```

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

```bash
bundle install
bundle exec rake db:create db:schema:load db:seed
```

Or if you only want to seed Lowell schools

```bash
bundle install
bundle exec rake db:create db:schema:load
bundle exec rake data:seed_only_lowell
```

Install the javascript dependencies

```bash
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.

### External APIs

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

### Javascript

Esbuild is used as the javascript bundler. Scripts for esbuild are defined in package.json e.g. `yarn build`. This script will run if in development with `bin/dev`.
The javascript testing library is jest. Manually run test with `yarn test`. Javascript tests will also run with `bundle exec rake`.

Stimulus is installed. Create a stimulus controller with `./bin/rails generate stimulus [controller]`. If you create a stimulus controller manually, you can add it to `index.js` with the command `stimulus:manifest:update`.

## Loading Data

### Loading Survey Item Responses
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:

```bash
# 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 exec rake data:load_survey_responses
```

Or if you only want to load data for Lowell

```bash
# locally
$ bundle exec rake data:load_survey_responses_for_lowell
```

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

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

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

There is also an example one-off task to load a single csv at a time.
```bash
bundle exec rake one_off:load_2018_19_student_responses
```

### Loading Admin Data Values
Loading admin data is similar to loading survey item responses.  Run the one of the following scripts to load admin data to a selected environment.

```bash
# locally
$ bundle exec rake data:load_admin_data

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

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

### Load Response Rates

Many parts of the site rely on the response rate table being populated.  The response rate is taken into account when determining if there is sufficient data to show

```bash
# locally
$ bundle exec rake data:reset_response_rates

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

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

### Load Student demographic information

Student demographic information is needed for the Analyze page disagregation

```bash
# locally
$ bundle exec rake data:load_students

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

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


Or if you only want to load students for Lowell schools

```bash
# locally
$ bundle exec rake data:load_students_for_lowell
```

### Load scores for each race
For performance, the scores for an individual race must be precalculated.  Make sure to load response rates, and student demographic information before recaculating scores by race

```bash
# locally
$ bundle exec rake data:reset_race_scores

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

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

### Load enrollment and staffing data

Enrollment and staffing numbers are taken from the DESE website.

To scrape staffing data from dese:
```bash
bundle exec rake scrape:staffing
```

To scrape enrollment data from dese:
```bash
bundle exec rake scrape:enrollment
```

Then to load it, run the seeder:
```bash
bundle exec rake db:seed
```

Or load it remotely on heroku
```bash
heroku run:detached -a mciea-beta bundle exec rake db:seed
```

Or to load it for the lowell dashboard specifically
```bash
bundle exec rake data:seed_only_lowell
```


### Upload cleaned data to SFTP
You can upload cleaned lowell data to the SFTP server with
```bash
bundle exec rake upload:lowell
```

## Running tests

### Single threaded test execution

Prepare the test database.

```bash
bundle exec rake db:test:prepare
```

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

```bash
RAILS_ENV=test rails c
```

Run the tests

```bash
bundle exec rake
```

### Automating test running

The guard-rspec gem will run the tests automatically when files are changed.

```bash
bundle exec guard
```

### Parallel test execution

The [parallel tests](https://github.com/grosser/parallel_tests) gem is installed. It's optional to use.

Set the `TEST_ENV_NUMBER` environment variable. For example, add this line to your `.bashrc`

```bash
export TEST_ENV_NUMBER="20"
```

Create the additional databases

```bash
bundle exec rake parallel:create
```

Run the tests in parallel

```bash
bundle exec rake parallel:spec
```

Run the tests with a specific number of processes

```bash
bundle exec rake parallel:spec[5]
```

### Viewing test coverage

```
xdg-open coverage/index.html
```

### Javascript tests

Run the javascript tests

```bash
yarn test
```

### Connecting to Heroku git

To add the heroku remote repository for beta run
`git remote add beta	https://git.heroku.com/mciea-beta.git`

To add the heroku remote repository for production run
`git remote add dashboard	https://git.heroku.com/mciea-dashboard.git `


## 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

```bash
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.

```bash
yarn build --watch
```

Start the puma web server

```bash
bin/rails s
```
