Hi Experts,

l have model called User  
class User \< ActiveRecord::Base  
apply\_simple\_captcha  
end

in view  
\<%= show\_simple\_captcha(:object=\>“user”) %\>

in controller  
@user = User.fiind(params[:id])  
if @user.valid\_with\_captcha?  
if @user.update\_attributes(params[:use])  
--------  
else  
---------  
end  
else  
--------------------  
end

in textfields are cleared, and shows error appropriate error like  
first\_name and last\_name is blank but i feeded all the data correct  
way except the captcha value, which shouldnt happen.

First, it seems to me that a model is not where a captcha might want  
to go. I personally feel it should be in the controller and view, but  
not in the model.

That said, I have a helper method (well, once I refactor it out into a  
method) which generates the captcha (for the view) and a simple  
function which validates it and returns either :success, :failure, or  
nil. :success means it matched. :failure means it did not. nil  
means it could not perform the check, either because it could not  
reach the servers or some internal error to my code. I treat this as  
:success and move on.
