hi all. I'm using the rails plugin acts_as_flying_saucer to generate a pdf, but the pdf doesn't work: i can save it ok, but when i try to open it i get this error message:
Unable to open document
File type SOR File (text/plain) is not supported
Here's my set up. I'm using rails 2.3.4 and the latest version of the acts_as_flying_saucer plugin. I have this route:
map.all_help '/help/all.:format', :controller => "help", :action => "all"
which goes to this controller action:
class HelpController < ApplicationController
acts_as_flying_saucer
def all
respond_to do |format|
format.html {
render :action => "all", :layout => "help_pdf"
}
format.js
format.pdf {
render_pdf :template => 'help/all.html.erb',
:layout => "help_pdf",
:send_file => { :filename => "my-filename.pdf", :type => "application/pdf"}
}
end
end
end
and i also have this mime type defined:
Mime::Type.register "application/pdf", :pdf
When i go to the page, /help/all.pdf, it generates a 0 byte pdf (which i can save ok) and i get the error message from the top of this post when i try to open it.
Going to the standard web page version of the page (/help/all) works fine. I thought maybe my java vm wasn't set up but it seems to be fine:
max-laptop:millionaire[subjects]$ java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)
I'm out of ideas at this point...grateful for any advice! max
EDIT: Just noticed that a bunch of error output is in my mongrel-running tab:

I'm wondering now if there's something wrong with the page i'm trying to convert to pdf. I ran the html version of the page past the w3c validator and the page validates ok. So now i'm stumped again...
EDIT 2: i think i'm getting closer now: looking in my log, i see
Rendering help/all.html.erb
html file: /tmp/ff4c8ff01d544500ea4bfea43e6108c1.html
Sending X-Sendfile header /tmp/ff4c8ff01d544500ea4bfea43e6108c1.pdf
So, i'd expect /tmp/ff4c8ff01d544500ea4bfea43e6108c1.html to have the html version of my page in it, but it's just a four line empty text file. No wonder flying saucer can't convert it. I don't know why it's saving an empty html file though.
EDIT 3: here's the html i'm currently trying to convert
