ERB Templates

A tag with an equals sign indicates that enclosed code is an expression, and that the renderer should substitute the code element with the result of the code (as a string) when it renders the template. Use an expression to embed a line of code into the template, or to display the contents of a variable:

Hello, <%= @name %>.
Today is <%= Time.now.strftime('%A') %>.

Comment markers use a hash sign:

<%# This is just a comment %>
