Rails - May 2010 - Generate a PDF from an existing HTML

Hi everyone,

I am having a lot of troubles with this issue the past few days and I would
like any suggestions to try to solve this.

I want to generate a PDF that has a really big report table from a given
HTML (I am not using wicked_pdf plugin because the only thing I want from
the HTML is that table. that being said I preferred to use the prawnto
plugin).

So what I am trying to do is parse the HTML using Nokogiri. I did something
like this in my reports controller: *@doc = Nokogiri::HTML(open("
http://localhost/reports/1"))*. The problem is that if I do this it gives
me
a Timeout error. I can parse almost any webpages that are not inside my own
project.

Well, my questions are: There is a better approach than doing this? Is there
someway that I can use open-uri library to open my own project?

I know that I could use the prawnto to generate a table for the report, but
the thing is that there are a lot of kinds of reports and for each one there
is a kind of calculation. So I am trying to bypass this by parsing the HTML.

Thanks in advance.

Regards,
Marco Antonio
