Thanks, Craig--I think my example was too terse. What I'm trying to
do is to pass a block of text to a view which may contain multiple
references to external models, and I'd like to interpolate those
references.
So, for example, if @thing.body = " This is the id of foo: <%= @foo.id
%> and this is its body: <%= @foo.body %> "
If @foo.id = 2 and @foo.body = "Norman", I'd like in the view
whatever.html.erb to have
<%= @thing.body %>
display
This is the id of foo: 2 and this is its body: Norman
Is there a way to do that? I also tried #{ ... } and am still getting
the literal rather than the interpolation.
Many thanks,
Craig
