README

This is a service learning project for CS4500 Spring 2017.

See the live version here: https://lvm-rails.herokuapp.com/

Instructions detailed for MacOS; however, it can easily be adapted to linux/unix environments

To get started, fork and clone down the repo as defined in the git flow article.

Getting Set Up

This section will walk through the installation of everything you'll need to get up and running. We'll be installing:

1. Homebrew
2. RVM
3. Ruby
4. Rails

Homebrew

Firstly, make sure you have standard command line tools installed for MacOS:

xcode-select --install

Agree to the prompts and wait until it has finished.

Now, run the following to install Homebrew (taken from the Homebrew front page):

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

RVM, Ruby, and Rails

RVM is a ruby version manager that allows you to easily install and switch between different ruby versions on the fly.

Running the following command will install RVM along with the latest version of ruby and rails:

curl -L https://get.rvm.io | bash -s stable --auto-dotfiles --autolibs=enable --rails

In order to bundle the dependancies for the rails app, you need to install the bundler gem:

gem install bundler

Running Locally

Once you've run through the initial setup, its time to get your local version up and running.

While inside the cloned repo:

bundle install

Note: If you get an error installing Nokogiri, try running the following command:

gem install nokogiri -- --use-system-libraries --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib/

After everything installs we need to run database migrations to setup our local database:

rake db:migrate

Now you're all set to run the rails server:

rails server

Now you're all set to run the rails server:

rails server

The application should be running and accessible at http://localhost:3000!

Explanation of relevant Rake (Ruby Make) Tasks:

rake db:drop

Drop the database.

rake db:create

Create a new database

rake db:migrate

Run all of the migration files in db/migrate in order. This brings the schema.rb file, which describes the database, up to date with the files in the directory.

rake db:seed_fu

Use the files in db/fixtures/ to seed the development database.

rake db:reseed

Drops, creates, migrates, and reseeds the database.

Seeding the database

Run rake db:seed_fu to seed the database with:

• 5 Affiliates
• 13 Coordinators
• 100 Tutors
• 100 Students
• 100 Student/Tutor Matches
• 100 Tutoring Sessions
• 20 Student Assessments
• 20 Tags
• 3 user accounts
  • [email protected] (role: tutor)
  • [email protected] (role: coordinator)
  • [email protected] (role: admin)
  • all passwords are "password"

Troubleshooting

• If you get "ActiveRecord::PendingMigrationError", this means that you need to migrate your database; that is, the application is expecting a newer version of your database schema than you have current set up. Simply run:

  rake db:migrate
