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?

P.S. There is a good enough reason for me wanting to do this 🙂

\<% coll.each do |itm| -%\>  
\<%= itm.value %\>  
\<% end -%\>

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)

You can use the ‘concat’ method instead of ‘puts’:

\<%  
coll.each do |itm|  
concat(itm.value, binding)  
end  
%\>

puts doesn’t append its arguments to the \_erbout variable, which is  
where erb accumulates its output.

You could do:

\<% coll.each {|itm| \_erbout \<\< itm.value } %\>

or something like that, though that’s really what \<%= %\> is for 🙂
