Now i want to make just simple back End to my first Ruby application
so i want to make header and include it to all of the pages in this back End so how i can make require or include to simple Html page in ruby (this page just i want to set some links in it )
in Php we just make page and require or include it by `require("my_page_name.php")` or `include("my_page_name.php")`
how we can make that in Ruby on Rails
