As a user, I can visit a custom landing page at localhost:3000.

main_controller.rb

def custom render html: "This is an awesome custom page" end

routes.rb

def custom
render html: "This is an awesome custom page"

end

As a user, I can see the names of my team members as hyperlinks on the landing page.

main_controller.rb

def David render html: "Hello" end def Lyssa render html: "Sweet" end

routes.rb

root 'main#custom' get '/custom' => 'main#custom' get '/David' => 'main#David' get '/Lyssa' => 'main#Lyssa' end

As a user, I can click on each team member's name and be taken to a page that displays a list of that team member's top three things. (Could be top three restaurants, activities, books, video games, hiking locations, beaches, doughnut shoppes, movies, etc.)

Lyssa.html.erb

These are my favorite things

• Coffee
• Cats
• Cookies

David.html.erb

These are my favorite things

• Food
• Travel
• Sports

main_controller.rb

def David end def Lyssa end

Params

As a user, I can visit a page called cubed that takes a number as a param and displays that number cubed.

main_controller.rb

def cubed @cubed = params[:cubed] @results = params[:cubed].to_i * params[:cubed].to_i * params[:cubed].to_i

end

custom.html.erb

Wanna play a game?

<%= link_to "cubed", "/cubed" %>

routs.rb

get '/cubed/:cubed' => 'main#cubed'

cubed.html.erb

This is Cubed

<%= @cubed %>

Your number cubed is <%= @results %>

As a user, I can visit a page called evenly that takes two numbers as params and displays whether or not the first number is evenly divisible by the second.

main_controller.rb

def evenly @evenly = params[:num1], params[:num2] if params[:num1].to_i % params[:num2].to_i == 0 @is_even = "Is evenly divisable" else @is_even = "Is NOT evenly divisable" end end

custom.html.erb

<%= link_to "evenly", "/evenly" %>

routs.rb

get '/evenly/:num1/:num2' => 'main#evenly'

evenly.html.erb

This is Evenly

<%= @num1 %> <%= @num2 %>

<%= @is_even %> As a user, I can visit a page called palindrome that takes a string as a param and displays whether it is a palindrome (the same word forward and backward).

main_controller.rb

def palindrome @palindrome = params[:str] if params[:str].downcase == params[:str].downcase.reverse @is_palindrome = 'This is a palindrome' else @is_palindrome = 'This is NOT a palindrome' end end

palindrome.html.erb

This is Palindrome

<%= @str %>

<%= @is_palindrome %>

routes.rb

get '/palindrome/:str' => 'main#palindrome'

As a user, I can visit a page called madlib that takes params of a noun, verb, adjective, adverb, and displays a short silly story.

main_controller.rb

def madlib @mablib = params[:noun], params[:verb], params[:adj], params[:adv] @noun = params[:noun] @verb = params[:verb] @adj = params[:adj] @adv = params[:adv] end

custom.html.erb

<%= link_to "madlib", "/madlib" %>

madlib.html.erb

This is madlib

<%= @madlib %>

There once was a <%= @noun %> who was doing <%= @verb %>. She loved <%= @adj %> ponies. The ponies were jumping <%= @adv %>.

route.html.erb

get '/madlib/:noun/:verb/:adj/:adv' => 'main#madlib'
