Best way to add comments in erb

Question

How do we add comments in erb files, if we do not want them to be generated into the html content?

Answer 1

Since .erb is by definition "embedded ruby", you can embed every ruby code between: <%= and the other: %>, typically all written in one line. In addition, ruby one-line comments start always with #, so the <%=# Comment %> style matches perfectly with both pure-ruby and erb styles for one-line comments.
