To avoid receiving an error when you attempt to access one of your routes and accidentally leave a trailing slash on the URL, you can use Rack::Rewrite to redirect the browser to the same URL without the trailing slash.
First add the gem to your Gemfile
gem 'rack-rewrite', '~> 1.5.0'Run bundle install

| enable :inline_templates | |
| get '/users/:id' do |
HTML and Sinatra really only support the GET and the POST methods. In order to be able to use the PUT and DELETE methods in Sinatra, you kind of have to "trick" the form to go to the right place. Then you can name the routes the proper way - otherwise you can only really work with GET and POST.
I used the Craiglist Jr challenge for some examples. Let's look at a quick example of a POST form/method/route- in this case, we're creating a new Craigslist article:
POST form and corresponding route:
<form action="/article/new" method="post">
