Quepid

Quepid makes improving your app's search results a repeatable, reliable engineering process that the whole team can understand. It deals with three issues:

1. Our collaboration stinks Making holistic progress on search requires deep, cross-functional collaboration. Shooting emails or tracking search requirements in spreadsheets won't cut it.

2. Search testing is hard Search changes are cross-cutting: most changes will cause problems. Testing is difficult: you can't run hundreds of searches after every relevance change.

3. Iterations are slow Moving forward seems impossible. To avoid sliding backwards, progress is slow. Many simply give up on search, depriving users of the means to find critical information.

Development Setup

I. System Dependencies

Using Docker Compose

Provisioning from an already built machine takes approximately 3 - 4 minutes. Provisioning from scratch takes approximately 20 minutes.

1. Prerequisites

Make sure you have installed Docker. Go here https://www.docker.com/community-edition#/download for installation instructions. And the Docker app is launched.

To install using brew follow these steps:

brew cask install docker
brew cask install docker-toolbox

NOTE: you may get a warning about trusting Oracle on the first try. Open System Preferences > Security & Privacy, click the Allow Oracle button, and then try again to install docker-toolbox

2. Setup your environment

Run the setup script:

bin/setup_docker

potentially seed the db to have something to work with (the output will print out credentials you can use for test users):

bin/docker r bin/rake db:seed:test

3. Running the app

Now fire up Quepid locally at http://localhost:3000:

bin/docker server

It can take up to a minute for the server to respond as it compiles all the front end assets on the first call.

We've created a helper script to run and manage the app through docker that wraps around the docker-compose command. You can still use docker-compose directly, but for the basic stuff you can use the following:

• Building the image: bin/docker build or bin/docker b
• Start the vm: bin/docker start or bin/docker t
• Stop the vm: bin/docker stop or bin/docker p
• Destroy the image: bin/docker destroy or bin/docker d
• Start the app: bin/docker server or bin/docker s
• Connect to the app container with bash: bin/docker bash or bin/docker c
• Run any command: bin/docker run [COMMAND] or bin/docker r [COMMAND]
• Run unit tests: bin/docker r bin/rake test:quepid

II. Development Log

While running the app under foreman, you'll only see a request log, for more detailed logging run the following:

tail -f -n 200 log/development.log

or

bin/docker run tail -f -n 200 log/development.log

Note: To clear the logs to avoid them getting too big run: cat /dev/null > log/development.log

III. Run Tests

BEFORE RUNNING TESTS

If you aren't using Docker, then create test database...

rake db:create RAILS_ENV=test

If you are using Docker, then prefix the below commands with bin/docker r to run them in your container.

There are three types of tests that you can run:

Minitest

These tests run the tests from the Rails side (mainly API controllers, and models):

bin/rake test

JS Lint

To check the JS syntax:

bin/rake test:jshint

Karma

Runs tests for the Angular side. There are two modes for the karma tests:

• Single run: bin/rake karma:run
• Continuous/watched run: bin/rake karma:start

Note: The karma tests require the assets to be precompiled, which adds a significant amount of time to the test run. If you are only making changes to the test/spec files, then it is recommended you run the tests in watch mode (bin/rake karma:start). The caveat is that any time you make a change to the app files, you will have to restart the process (or use the single run mode).

All Tests

If you want to run all of the tests in one go (before you commit and push for example), just run the special rake task:

bin/rake test:quepid

Performance Testing

If you want to create a LOT of queries for a user for testing, then run

bin/docker r bin/rake db:seed:large

You will have two users, [email protected] and [email protected] to test with.

IV. Debugging

Debugging Ruby

Debugging ruby usually depends on the situation, the simplest way is to print out the object to the STDOUT:

puts object         # Prints out the .to_s method of the object
puts object.inspect # Inspects the object and prints it out (includes the attributes)
pp object           # Pretty Prints the inspected object (like .inspect but better)

In the Rails application you can use the logger for the output:

Rails.logger object.inspect

If that's not enough and you want to run a debugger, the byebug gem is included for that. Add byebug wherever you want a breakpoint and then run the code.

Caveat: You might have to stop spring (bin/spring stop) or restart the server to get it to execute the breakpoint.

Debugging JS

While running the application, you can debug the javascript using your favorite tool, the way you've always done it.

The javascript files will be concatenated into one file, using the rails asset pipeline.

You can turn that off by toggling the following flag in config/environment/development.rb:

# config.assets.debug = true
config.assets.debug = false

to

config.assets.debug = true
# config.assets.debug = false

Because there are too many Angular JS files in this application, and in debug mode Rails will try to load every file separately, that slows down the application, and becomes really annoying in development mode to wait for the scripts to load. Which is why it is turned off by default.

PS: Don't forget to restart the server when you change the config.

Convenience Scripts

This application has two ways of running scripts: rake & thor.

Rake is great for simple tasks that depend on the application environment, and default tasks that come by default with Rails.

Whereas Thor is a more powerful tool for writing scripts that take in args much more nicely than Rake.

Rake

To see what rake tasks are available run:

bin/rake -T

Note: the use of bin/rake makes sure that the version of rake that is running is the one locked to the app's Gemfile.lock (to avoid conflicts with other versions that might be installed on your system). This is equivalent of bundle exec rake.

Common rake tasks that you might use:

# db
bin/rake db:create
bin/rake db:drop
bin/rake db:migrate
bin/rake db:rollback
bin/rake db:schema:load
bin/rake db:seed
bin/rake db:setup

# show routes
bin/rake routes

# tests
bin/rake test
bin/rake test:js
bin/rake test:jshint
bin/rake test:quepid

Thor

The see available tasks:

thor list

Examples include:

case
----
thor case:share CASEID TEAMID  # shares case with an team

ratings
-------
thor ratings:generate SOLRURL FILENAME  # generates random ratings into a .csv file
thor ratings:import CASEID FILENAME     # imports ratings to a case

user
----
thor user:create USERNAME PASSWORD             # creates a new user
thor user:reset_password USERNAME NEWPASSWORD  # resets user's password

To see more details about any of the tasks, run thor help TASKNAME:

thor help user:create
Usage:
  thor user:create USERNAME PASSWORD

Options:
  -p, [--paid], [--no-paid]

Description:
  `user:create` creates a new user with the passed in username and password.

  EXAMPLES:

  $ thor user:create [email protected] mysuperstrongpassword

  With -p option, will mark the user as paid

  EXAMPLES:

  $ thor user:create -p [email protected] mysuperstrongpassword

Elasticsearch

You will need to configure Elasticsearch to accept requests from the browser using CORS. To enable CORS, add the following to elasticsearch's config file. Usually, this file is located near the elasticsearch executable at config/elasticsearch.yml.

http.cors:
  enabled: true
  allow-origin: /https?:\/\/localhost(:[0-9]+)?/

Dev Errata

I'd like to use a new Node module

Typically you would simply do:

yarn add foobar

which will install the new Node module, and then save that dependency to package.json.

I'd like to test SSL

There's a directory .ssl that contains they key and cert files used for SSL. This is a self signed generated certificate for use in development ONLY!

The key/cert were generated using the following command:

openssl req -new -newkey rsa:2048 -sha1 -days 365 -nodes -x509 -keyout .ssl/localhost.key -out .ssl/localhost.crt

PS: It is not necessary to do that again.

What you need to do:

1. Drag .ssl/localhost.crt to System in Keychain Access (this is for OS X)
2. run (this is for Ubuntu/Vagrant):

• sudo cp .ssl/localhost.crt /etc/ssl/cert
• sudo cp .ssl/localhost.key /etc/ssl/private
• sudo c_rehash

3. In Procfile comment the part that uses puma and uncomment the part that uses thin
4. In .env make sure you add FORCE_SSL=true
5. Restart the server
6. Go to https://localhost:3000

PS: Why are we using both puma and thin? Because I simply could not figure out how to get puma to work properly with SSL and did not want to spend any more time on it!

QA

There is a code deployment pipeline to the staging-quepid.herokuapp.com site.
