Hello,
I have some problems with external proces, which is started by rails.
I have found something about generate pdf in rails:
http://wiki.rubyonrails.org/rails/pages/HowtoGeneratePDFs
I would like use htmldoc
but I have a problem with broken pipe.
When I run it directly from shell everything is ok,
but when I ruby it from method in rails controller,
I see "Broken pipe".
I think, that there is a problem, because rails are cgi process and
htmldoc not. How to improve this?
Can I run htmldoc as cgi process?

Code:

generator = IO.popen("#{htmldoc_env};htmldoc -t pdf --path
\".;http://#{@request.env["HTTP_HOST"]}\" --webpage -", "w+")
generator.puts @template.render("article/pdf")
generator.close_write
send_data(generator.read, :filename => "test.pdf", :type =>
"application/pdf")
