I have a loop that I iterate through in my view.
<%
coll.each do |itm|
puts(itm.value)
end
%>
How do I render the itm.value without using a <%= %> tag? Should puts
not work?
Joerg
P.S. There is a good enough reason for me wanting to do this :-)

You can''t use puts in views. What is it you''re trying to do? You''ll have to give us the good enough reason i think :0) Steve Joerg Diekmann wrote:> I have a loop that I iterate through in my view. > > <% > coll.each do |itm| > puts(itm.value) > end > %> > > How do I render the itm.value without using a <%= %> tag?

Joerg, I haven''t found a good way to do what you want. I think just
separate code blocks is the cleanest.
<%coll.each do |itm|%>
<%=itm.value%>
<%end%>
It''s ugly, but more readable (to a simpleton like me) than <%
coll.each
{|itm| _erbout << itm.value } %>

You could do:
<% coll.each {|itm| _erbout << itm.value } %>
or something like that, though that''s really what <%= %> is for

You can use the ''concat'' method instead of ''puts'': <% coll.each do |itm| concat(itm.value, binding) end %> Cheers, -DF On 5/31/06, Joerg Diekmann <joergd@pobox.com> wrote:> I have a loop that I iterate through in my view. > > <% > coll.each do |itm| > puts(itm.value) > end > %> > > How do I render the itm.value without using a <%= %> tag?
