Anything that's not parsed as some sort of Haml command is literal text.
So, for your purposes, you could do:
%h2
by
= @book.authors.map{|a| a.name}.join(", ")
Alternately, if you're using trunk, you can embed the Ruby directly into
the text like you would a Ruby string with the "==" command:
%h2
== by [EMAIL PROTECTED]|a| a.name}.join(", ")}
A cleaner way to do this might be to define a helper method and use that.
# In controller_name_helper.rb
def author_names
@book.authors.map{|a| a.name}.join(", ")
end
-# In controller_name.haml
%h2
== by #{author_names}
There is no way to suppress a newline in Haml. There's no need to... if
you need to use script that shouldn't output, simply use the "-"
character, and it won't create a newline. For example,
%ul
- 3.times do |i|
%li= i
Hope that helps,
