Making and Deploying a new Rails web application using Postgresql

Rails New Development and Deploy

#1 First open your terminal program and type cd to go to your home directory:
cd

#2 To create a new rails application called q_man using postgresql: 
rails new q_man -d postgresql
#3 Enter the application directory:
cd q_man
#4 Start the local webserver
rails s

#5 open your web browser and go to this address:
http://localhost:3000

#6 Stop your local server by holding the control key and pressing c
## or you can leave it running, open a new terminal window, and cd to the q_man directory
control-c

#7 Initialize a local git repository
git init 
#7.5 View your git status
git status
#8 Add all the files in your q_man directory
git add .
#9 Commit those files to the repository with a nice message
## you can change the message to whatever you like
git commit -m "adding blank rails app to local repo"

#10 Install the heroku gem if you don't have it already
gem install heroku
#11 Setup your new rails app to deploy to Heroku 
##  this step may ask you for your Heroku login and password 
### (if you get a message about an ssh-key please let us know)
##  we have to specify to use the Cedar stack, which tells Heroku we are using Rails version 3
heroku create --stack cedar
#12 Deploy your new application to Heroku
git push heroku master
#13 Open the app you deployed to Heroku in your web browser
heroku open

#14 Open the q_man directory in Sublime
open->q_man
#15 Find the index.html file
q_man->public->index.html
#16 Modify the Welcome message, or some other part of the index page text

#17 Re-start your local webserver if you stopped it before with this command:
rails s
#18 View your changes in your web browser
http://localhost:3000
#18.5 Stop your server or go to the tab that is not running your webserver
control-c

#19 View what you have changed
git status
#20 Add your changes
git add .
#21 Commit your changes (you should have a nicer message than "message")
git commit -m "message"

#22 Deploy your changes to Heroku
git push heroku master
#23 View your changes on Heroku
heroku open

#24 Modify your database configuration file with your postgresql username and password
##  change the username and password fields in the development and test sections
q_man->config->database.yml

#25 Apply your database configuration changes from your q_man directory at the command line
rake db:create
rake db:migrate

#26 Add and commit your database changes to your repository
git add .
git commit -m "message"

#27 Deploy your changes to Heroku
git push heroku master
heroku open

In class, we then worked out the right scaffold command for generating the Question resource, with a title attribute of type string, and a body attribute of type text. You can work this out by reading the helpful docs displayed when you run rails generate scaffold, or see the next comment for the answer. ;]

rails generate scaffold question title body:text

rails generate scaffold RESOURCE_NAME ATT1:TYPE ATT2:TYPE ...
