CGI with Ruby

Ruby
1

Hi,
I am having some problems with Ruby CGI code. What I am trying
to do
is to use the Ruby WordNet Modules when working with some CGI programs.
I
need the CGI program to call a couple of functions defined in a
different
module. The CGI program seems to run fine when run from the command line
(offline mode) but when run from a browser it does not load the WordNet
modules.

   Could someone please help out with this.

   I am using wordnet 2.0 Ruby 1.8 apache2 and Suse 9

   I could include the code but there is tons of it so I could

include
whatever may be needed ( not sure what that is as of now)

What does your apache error log say?

Hey john,
Thanks for the reply

   Here is the Apache error log entry.

[Wed Jul 12 01:35:49 2006] [error] [client 192.168.0.34]
/usr/lib64/ruby/site_ruby/1.8/linguistics/en/wordnet.rb:117:in
`wnL\exicon’:
WordNet functions are not loaded: No such file to load – wordnet
(NotImplementedError), referer:
http://192.168.0.\34/cgi-bin/TextToTermsStart.rb?name=Harish&account=Account1&theme=Theme1

Interestingly I get the same error when I ssh into the server from a
windows
machine (putty) and try to run the program from command line (although
the
program works when I run it from the server on command line) Also the
program runs when I ssh into the server from another Linux machine. ( I
have
tried to access it through a browser from both windows and Linux and it
does
not work )

here is that error msg:

suseserver2:/srv/www/cgi-bin # ruby extract_from_string.rb
/usr/lib64/ruby/site_ruby/1.8/linguistics/en/wordnet.rb:117:in

method_missing' from extract_from_string.rb:53:in extractSyn’
from extract_from_string.rb:87:in `extractPhrase’
from extract_from_string.rb:211

I thought it had something to do with permissions and have tried
changing
them around. Then tried some things with the Apache config, but since
the
ssh is not working it looks like that is not the error. I am at a
complete
loss…

is there some Wordnet stuff I need to preload

require looks for a filename, so, yeah, that may be the same file.
Maybe you’ve got more than one wordnet.rb file in the different
directories that Ruby’s require goes looking for files in?

Sorry I can’t help more. Maybe someone here can outline some of the
tricks they use for debugging CGI scripts…

Just to add on

was looking through the wordnet files (the ones that got installed) and
here is a part

file wordnet.rb:

This file contains functions for finding relations for English words.

It

requires the Ruby-WordNet module to be installed; if it is not

installed,

calling the functions defined by this file will raise NotImplemented

exceptions if called. Requiring this file adds functions and constants

to
the

Linguistics::EN module.

module Linguistics
module EN

    @hasWordnet             = false
    @wnError                = nil
    @wnLexicon              = nil

    # Load WordNet and open the lexicon if possible, saving the

error
that
# occurs if anything goes wrong.
begin
( ERROR GENERATED HERE)
require ‘wordnet’
@hasWordnet = true
rescue LoadError => err
@wnError = err
end

why is it that wordnet.rb is including wordnet? its the same file right?
