Telling the difference between Ruby and Rails and how they work together. Useful for new programmers.

1. Who’s Ruby and
What’s Rails
Allison Sheren

2. the same
!=
thing

3. The only
search
result:

4. Not ruby
Not ruby
This is ruby
Not ruby
Not ruby

5. Built off of Ruby (the original), there
are expansion packs (Rails). Rails is an
open source web application framework
built on Ruby.

6. The basics:
Ruby uses IRB,
Gems, and is
an objectoriented
programming
language
Like resource
cards, dice,
resource map
pieces,
houses,
cities, and
roads.

7. What were
all those
words you
just said?

8. Breaking it down
- Gems are: a packaged library
or application.
Rails is a gem that you use
with Ruby. Who has a favorite
gem?

- IRB is: interactive ruby.
Lets you try out things using
the command line

9. The New Stuff!
- follows rules
like MVC and DRY
- uses Rails
console
- can query a
database
- uses things like
rails generate
(outputs generic
code) or a scaffold
Includes special
things like ships,
extra water, Star
Trek related pieces,
etc.

10. What?!
- MVC =
model, view,
controller
- DRY = Don’t
repeat
yourself

11. Scaffoldin
g
Same blueprint,
Different house

12. Rails
combines Ruby
with HTML,
CSS, and
Javascript to
create a web
app

13. This is an
example of
html with
ruby code.
It’s view
code which
is in rails
but not
ruby.

14. What to learn
first?
My recommendation:
Learn ruby first
then add in rails
BUT
there are better
tutorials out there
for ruby on rails
that allow you to
actually build
something
