Recaptcha (or other captchas)

Does anyone have any suggestions for a best practice implementation of
Recaptcha (or other captchas - if you recommend going another route,
I''m
all ears)? I''ve found the recaptcha gem and a plugin but I
don''t know
which is the best implementation, and I haven''t found a thorough
tutorial plus example code for either.

Thanks

Re: Recaptcha (or other captchas)

I have implemented Recaptcha on the registration page of this site:
http://www.satechevents.co.za/account/register

I am using the gem here:
http://www.loonsoft.com/recaptcha/

Thanks, Schalk. I liked the idea of the plugin (I prefer plugins because 
I can jump right in to the code on which the app is dependent) but the 
gem seemed easy enough. However, I''ve followed the instructions and
I''m
stuck on this;

/Library/Ruby/Gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies.rb:278:in
`load_missing_constant'': uninitialized constant RecaptchaClient 
(NameError)

How are you including the gem? I created an initializer 
(recaptcha_credentials.rb) with this inside;

RecaptchaClient.new(:rcc_pub=>''my_code'',
:rcc_priv=>''my_code'')

...because I thought it was best to keep the environment.rb free of 
these things. I''ve tried putting it in the environment.rb, but that
just
breaks, too (same error). Where am I going wrong?! Mongrel loads if I 
don''t include the RecaptchaClient.new.

Also, I saw this when I was installing the gem;

WARNING:  RubyGems 1.2+ index not found for:
  http://www.loonsoft.com/recaptcha/pkg/

RubyGems will revert to legacy indexes degrading performance.
Successfully installed recaptcha-0.1.49
1 gem installed

Thanks Fred. Since the last post I''ve moved to the plugin, however,
I''m
struggling with that one, too. It should be insanely simple; I just need 
to set the public and private keys as variables in the environment.rb 
(or an initializer, if applicable) - but I just can''t get it to work;

http://pastie.org/284245

I can hack the plugin to use the keys as strings without using variables 
(means removing an ''unless'' condition, too), but that defeats
the point
of a well test plugin. Can you see what I''m doing wrong here?

Thank you, this works like a charm;

ENV[''RECAPTCHA_PUBLIC_KEY''] = ''some_key'';

Re: Recaptcha (or other captchas)

And should I be using any specs for recaptcha? I struggled to find much 
through a Googling...

Re: Recaptcha (or other captchas)

The best is always hard to define depending on personal opinion which  
is extremely variant from one to another. Choose something you  
yourself feels comfortable with and then go through the documentation  
and install. I''ve seen that ReCAPTCHA can be used with Ruby on Rails  
and trying "Recaptcha Ruby Rails" into google got me this result:
http://deadprogrammersociety.blogspot.com/2008/02/recaptcha-on-rails.html
  which seems fairly detailed.

Thanks Ryan. That tutorial looks handy. I managed to implement the 
plugin in the same way that hte tutorial describes (if only I had had it 
at the time). I''ve seen very little on the spec/test front on 
integrating recaptcha. Maybe it''s not so important, then?
