My-Ruby-Journey: Rails Ruby Sinarta

Chapter 49: Sinatra Course #6

Unit 6 starts on page 38. Instruction on how to connect to Postgress: http://gist.github.com/68277
Page 39 was the code for crud.rb and pages 40-43 explains the different parts of the code.
Created new.erb and show.erb. (p.42, 43)
Ran "ruby crud.rb" and it worked. (p.43)
Stopped on Exercise at bottom of page 43. Open Source Web Designs: http://www.oswd.org/

Chapter 48: Sinatra Course #5

Text Reversing Service: Unit 5 starts on page 32.
Did everything on page 32 and it worked as shown on page 33.
Did everything on page 34 and saw no change. (p.34)
QUESTION: Where to put show.erb? My guess is under views.
Made the changes on top of page 35 and it worked. (p.35)
Did #1 at bottom of page 35, but only had partial information (did not know "severe-night-58" string yet; see step 4 on next page) to do step #2. Did as much as possible.
Step 3: Set up Git. (done) (p.36)
Step 4: Set up Heroku. Now I have step 6 above string. It is "deep-wind-75".
Step 5: Created remote add alias. Used "page36" $ git remote add page36 git@heroku.com:deep-wind-75.git
Step 6: Deployed to Heroku: $ git push page36 master (p.37)

End of Unit 5.

Chapter 47: Sinatra Course #4

Views: Did the stuff on page 27 and 28 to add Views to electric-robot-51 and it worked.
Now to Layouts: Created layout.erb and copies contents from zip file. (p.29)
Then created "public" directory and copies contents (7 files) from zip file .(p.29-30)
$ git add . ; $ git commit -m 'committing public files'

Chapter 45: Sinatra Course #2

Unit 2 starts on page 19. Moved App. 1 (GIT) to this section.
Created directory "mkdir sinatra_program" under gitlocalrepo directory. (p.19)
Then put "require 'sinatra' into myapp.rb and ran it. :$ ruby myapp.rb (p.20)
== Sinatra/0.9.1.1 has taken the stage on 4567 for development with backup from Mon
grel
Then I open and browser window with http://localhost:4567 and got this: Sinatra doesn't know this ditty.
Try this:
```
get '/' do
"Hello World"
end
```
Then I add "get" handler with just a comment and it worked. Then added 'Welcome from RubyLearning' and it worked. (p.21)
PROBLEM: Have a problem getting Cygwin to take the Control-C.
QUESTION: Unclear why GIT was mentioned in this section. We did not use it.
