<% end %>

Answer 2

Dude, this is not the first time you've posted a simple question here. Learn to first formulate a query, then enter it into Google, and then follow the links and read, preferably google in English. There will be more results.
And read rusrails.ru from cover to cover.

Answer 3

<%= @teachers.map(&:name).join(', ') %>
