The following was typed up a bit back during one of my projects--
I did clean it up some, because my initial "jot down" was as I went and well, good thing it wasn't on paper.
Disclaimer: This could probably use more of an edit, but until then...

SETTING UP PROJECT

Where will my project live?
$ cd /vagrant/src

ex:
if opening up fresh terminal window (as in my local machine):
$ cd ~/Desktop/vagrant
and RUN vagrant

START:
vagrant up

STOP:
vagrant halt

Create a new project/app that uses postpres
$ rails new SITENAME --database=postgresql

NOTE:
If you run this and it tells you rails is not installed or something along those lines-- is vagrant up? are you in the correct terminal within environment?

NOTE:
Make sure vagrant is running/ run vagrant, open vagrant terminal window and try again.

• Did you see a nice wave of files being generated? *
  your proj should have been created at this point

Open project in text editor (ex: Sublime)

Open database.yml

  username: postgres
  password: password
  host: localhost

NOTE:
above would be for development, test, and production
be careful-- double check database adapter-- should say postgresql
file is whitespace sensitive^^

I add above info in database file under default--
if you look at the file under dev, test, and prod you can tell they are inheriting from the default section-- instead of typing it out 3x I just input it 1x

RETURN TO TERMINAL WINDOW

Make sure you are in the project directory

CREATE intial database
$ rake db:create:all

START SERVER

1. Open a 2nd terminal window if you havent done so already
2. Make sure it is terminal window from within environment as you did with how you created your project above
3. Go to project directory

$ rails s OR $ rails s -b 0.0.0.0

Check localhost web page -- you should be greeted with a welcome aboard page ex: http://localhost:3030/

ERROR:
Checking terminal, error saying could not create DB Upon rechecking I noticed I left username/pw under production NOTE: all 3 should match with info from above

SETTING UP WEB DEV PIPELINE

SETUP GIT

$ git init .
$ git add --all
$ git commit -am "initial commit"

SETUP GITHUB

GO to Github

• NEW REPO button

• NAME it, leave PUBLIC button
  NOTE: DO NOT check initialize readme (default will get generated ready to be edited with specific project info)

• CREATE REPO button

AFTER page reloads "Push existing repo from command line..."

NOTE:
SSH will use pw already setup, https will require username/pw each push

COPY/PASTE:
git remote add... AND THEN, git push... IN TERMINAL

NOTE: Each command will populate info specific to github acct

HEROKU

gem 'rails_12factor', group: :production
NOTE: above goes in gem file

UPDATE: above gem is not needed with Rails 5 :)

$ bundle install

NOTE:
Installing the above gem

• production efficiency, speeds up project load times
• allows for errors in heroku logs, useful for troubleshooting rather than generic messages

UPDATE production config file
config/env/production.rb

CHANGE line

"Do not fallback to assets pipeline if precompile asset is missed"
config.assets.compile = false

into =>

"DO fallback to assets pipeline if precompile asset is missed"
config.assets.compile = true

NOTE: remember to back up/ push up code to github with any major changes

DEPLOY to HEROKU

$ heroku create APP NAME
$ git push heroku master

NOTE: URL by "launching..." is heroku url BUT, if you visit site at this time--
you'll be greeted with "the page you were looking for doesn't exist" --

why?

because... page hasn't been built yet :)

BASIC SETUP COMPLETE :)

Grab your wireframe or go create one and get jammin'
