1 New Rails Application

Make sure you have ruby installed. I am using rbenv to maintain different versions of ruby across projects.

% rbenv -v
rbenv 1.1.2

% ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin19]

1.1 Install rails

% gem install rails -v '~> 6.0.0'

% rails -v
Rails 6.0.3.6

1.2 Create application

% rails new blog --skip-active-record --skip-bundle

% cd blog

Note: You may receive a warning like this:

Could not find gem 'puma (~> 4.1)' in any of the gem sources listed in your Gemfile. Run bundle install to install missing gems.

Disregard it as we will be taking care of gem installation in a moment.

Add following to the Gemfile:

gem 'mongoid', '~> 7.0.5'

Install gem depndencies.

% bundle install

Generate the default Mongoid configuration.

% bin/rails g mongoid:config

Install yarn.

% npm -v
6.14.4

% npm install --global yarn

Install webpacker.

% rails webpacker:install

(Optional) Push your code to a Github repository

Create an empty repository named blog on github.com.

% git init .
% git add .
% git commit -m 'Initial commit'
% git remote add origin git@github.com:jagdeepsingh/blog.git
% git branch -M main
% git push -u origin main

Make sure a MongoDB server is running locally.

Run application.

% rails s

Your application is now running on http://127.0.0.1:3000.
