I have my code working on my local machine no problem, but when I upload
to the server the RJS effects I have aren’t working. The server is
running Ubuntu Dapper w/ lighttpd while on my local machine I’m using
webrick.
For kicks I shut down lightty and booted my app on the server with
webrick and it works fine. So it’s definitely a lightty issue.
Anyone else seen it and/or know how to resolve?
Just a guess, but it sounds like lighty is munging your javascript
files somehow. Can you further illuminate your server’s setup? Does
the following return a gob of javascript code?

Yeah I just see code when I try that. I shut down lightty and used
webrick as a test and it works. So it’s definitely an issue with
lighttpd. 
I’m on version 1.4.11 using Ubuntu Dapper. Looks like
1.4.13 is out but not yet in the repos.
I suppose I will have to try manually installing it to see if that
solves my issue.

Here is my lighttpd.conf:

server.document-root = “/var/www/myapp/public/”

Ok, I updated to lighttpd 1.4.13 (latest) but am still having the same
problem. I am stumped.
Anyone have any ideas? Here is the .rjs in question:
page << “var a=0;”
if @mapsnew
for mapsnew in @mapsnew
page << “var e=new GLatLng(#{params[:evt_latitude]},
#{params[:evt_longitude]}).distanceFrom(new GLatLng( #{mapsnew.latitude}
, #{mapsnew.longitude.to_f} ))/1000;”
page << “if(a==0){”
@evnt=Event.find(mapsnew.event_id)
page.replace_html ‘maplist’, content_tag(‘li’, “#{@evnt.event_head[0…25]}…” , :id =>
‘list_item’ )
page << “}else{”
page.insert_html :bottom, ‘maplist’, content_tag(‘li’, “#{@evnt.event_head[0…25]}…” , :id =>
‘list_item’ )
page << “}”
page << “a=a+1;”
end
else
page.replace_html ‘maplist’, content_tag(‘li’, “No events to
list!!!” , :id => ‘list_item’ )
end

I finally solved this… firebug gave me some clues. Turns out my POST
requests were showing up like this:
Connection: close
Transfer-Encoding: chunked
38.909643Content-Type: text/javascript
Set-Cookie: _session_id=246ae40922c0fd45f1514aeb4bf790ae; path=/
Cache-Control: no-cache
Date: Tue, 10 Oct 2006 19:41:35 GMT
Server: lighttpd
That 38.909643 figure was obscuring the Content-Type so it wasn’t
getting picked up. I had a print statement which was putting out that
number and as soon as I erased it from my code everything started
working again.
I have no idea why lightty would pick up a print statement as part of
the post though. Seems like that has to be a bug.
Anyway, thanks for taking the time to look through this with me!
Really strange. Your config looks fine (although I speak from only
having run lighty+fcgi a few times, I’ve switched to mongrel+pen+lighty
since).
A few more things to check:
Anyone else? Am I missing anything?
Ooh, ouch.
Looks like others have run into this as well:
http://source.mihelac.org/articles/2006/06/05/do-not-use-puts-in-rails
I like to use “logger” and “raise object.to_yaml” during debugging.
The former will harmlessly log into your log/#{RAILS_ENV}.log file and
the latter is so noticeable (and easy to grep for) it’ll be hard to
miss it during a deploy.
