What is the Rails 3 way to comment out One Line or Multiple lines of code in a View? And so it doesn't show up in the HTML Source

A:
which "blocks" do you mean? html? then you can use ruby code? <%# code %>

Sorry not blocks, just how to comment out a Line or LInes, in a non-HTML way. I don't want it in the HTML source

Strange but that doesn't seem to always work... I get a compile error when using it in a view inside a loop like <% @projects.each do |project| %>

A:
To comment out a single line ob ruby code use
<%# code %>
or for multiple lines
<%
=begin
your code
=end
%>
EDIT: Here a example to comment out a loop in an view. The =begin and =end must stand directly at the beginning of the line. There couldn't be any spaces or tabs.
<h1>Listing posts</h1>
<table>
<tr>
<th>Title</th>
<th>Text</th>
<th></th>
<th></th>
<th></th>
</tr>
<%
=begin
%>
<%@posts.each do |post| %>
<tr>
<td><%= post.title %></td>
<td><%= post.text %></td>
<td><%= link_to 'Show', post %></td>
<td><%= link_to 'Edit', edit_post_path(post) %></td>
<td><%= link_to 'Destroy', post, :confirm => 'Are you sure?', :method => :delete %></td>
</tr>
<% end %>
<%
=end
%>
</table>

Check this out it doesn't work, it still shows a list of %> on the page; <%# <td><%= link_to 'Destroy', project, :confirm => 'Are you sure?', :method => :delete %></td> %>

Thanks for the example, in the above, how would you comment out JUST the Destory line?

I updated my post above, the comments are a bit confusing because you can see no newlines.

Can you update your post to show how to comment out JUST the Destory line?

you can wrap this line with the =begin =end tags like in the edited example code.another (dirty) solution is to use a false condition e.g. <% if 1 == 2 %><td><% link_to 'Destroy', post, :confirm => 'Are you sure?', :method => :delete %></td><% end %>then you can write it in a single line. but be careful, with this method you can't directly see that the code is commented out.
