Hi Group.
I am just starting with Ruby on Rails. I have been stuck up (not
exactly stuck up but I need to figure this out). I need to comment a
block of code with HTML and RUBY code. Is there any way of commenting
an entire block of code?
Example:
class="s\_view\_comments\_row"\>
\<%if comment.user.photo\_exists?%\>
How do I comment these 4 lines so that they are not executed when
the .rhtml is parsed.
Lalit

AFAIK erb has no block commenting syntax. Here’s what I usually do
though:
\<% if false -%\>
.... \<% end -%\>
