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

For block comments:

<% if false %>
    code to be commented out...
<% end %> 

Answer 2

Use the <%# %> sequence, e.g.

<%# This is a great comment! %>

Answer 3

For Record

<%# This is a great comment! %>

<%#= This is a great comment! %>

Answer 4

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.

Answer 5

I have a Windows setup, and this <%-# %> sequence is the only one that works for me:

Example:

<%-# This is a sample comment! %>
