Differences

• Route is included and defined

• View is defined by user

• Manually created

RailsSinatra

• Route is not included

• Rendered view is defined by convention

• Actions can be automatically generated by scaffolding

So where are the routes and views?

get ‘/posts’ => post#index

app/views/posts/index.html.erb

/app/config/routes.rb

Convention over configuration

• With Sinatra you are free to name and define your controller actions/routes

• examples:

• get “/showindex” or post “/creatething”

• “In Rails there should be no guessing to what a controller action is doing” - Shadi
