how to output HTML in a view within a <% %> (not a <%= %> )

Hi,

How can I output/render text within a view, but within a block of ruby code
that is surrounded by <% %> ?

I know that use of <%=  %> works, but if I have several lines of ruby in
the
view that is within <%  %> and I want to output text to be part of the
HTML
how can I do this?

For example something like "puts" or "render" but actually
works within a
*.rthml view.

Thanks
Greg

Re: how to output HTML in a view within a <% %> (not a <%= %

The following:

  <% _erbout += Time.now %>

and

  <% concat Time.now, binding %>

are the same as:

  <%= Time.now %>

Re: how to output HTML in a view within a <% %> (not a <%= %

While this is the way to do it, I would suggest writing multi-line ruby 
code as a helper and to return the HTML-Code. Something like this:

--
module YourControllerHelper
  def my_output(model)
    name = strip_tags(model.name)
    description = strip_tags(model.description)
    html = <<HTML
      <h1>#{name}</h1>
      <p>#{description}</p>
HTML
  end
end

View:

<%= my_output %>
--

Another version is to substitute the here_doc with a render-call using a 
partial.
There are multiple versions to accomplish this, but the above is the 
quickest to write ;).

Re: how to output HTML in a view within a <% %> (not a <%= %> )

tks Ian - so it sounds like what I''m asking isn''t possible?
(i.e. and you do
have to break the script area back to HTML, if you know what I mean)

Re: how to output HTML in a view within a <% %> (not a <%= %> )

Remco gave you the answer: use the concat method.

Stylistically, though, you should only use the concat if it''s truly
unavoidable. In general, you shouldn''t be putting too much Ruby code
into your views. As Florian suggests, think about pushing this out to
a helper so that you can use the clean, readable <%= %> tags.

Re: how to output HTML in a view within a <% %> (not a <%= %> )

oh...I didn''t see a response from Remco yet(?)

I''m basically just curious to understand whether it was possible to
output
from within <%  %>, to relate possible use within rails views with Java
JSP.   The answer seems to be that it is not possible, which is fine, I just
wanted to understand.

So you have to do:
<% @foo.each do |bar| %>
  <%= bar %>
<% end %>

As there is no way of doing something like:
<%
   @foo.each do |bar|
     render_to_view bar
   end
%>

tks
Greg

No, in fact the first code is roughly translated to the second version
using _erbout (or maybe concat). Nothing prevents you to directly using it :

<%
   @foo.each do |bar|
     _erbout += bar
   end
%>

Re: how to output HTML in a view within a <% %> (not a <%= %> )

ok thanks Lionel - I''ve understood the concat method too.  Seems like
concat
would be the slightly less "under the bonnet" approach to use. 
Neither
seemed to get mentioned in the "Agile Web Development with Rails" book
in
this context which is interesting.
