Here’s the full error:

1. Error:  
test\_add\_message\_to\_existing\_ticket(TicketTest):

The code in question:  
t.messages \<\< Message.new({ :body =\> “ya message body”, :user =\>  
users(:bob) })

t is a Ticket object, and a Ticket has\_many :messages. Both Ticket  
and Message mixin acts\_as\_paranoid. I also get the same error if I  
call Ticket#destroy.

I think this may have been asked on the list already, but I can’t find  
anything in gmane, ruby-forum, or google so I’m lost.

Here’s how the method originally appears:

def validate\_find\_options(options)  
options.assert\_valid\_keys [:conditions, :include, :joins, :limit, :  
offset, :order, :select, :readonly, :with\_deleted]  
end

and here is the edited version:

def validate\_find\_options(options)  
options.assert\_valid\_keys [:conditions, :include, :joins, :limit, :  
offset, :order, :select, :readonly, :group, :with\_deleted]  
end

Ideally I suppose acts\_as\_paranoid would somehow figure out the keys  
that ActiveRecord finds acceptable, then append :with\_deleted on to the  
lsit, but I don’t know how one would do that.

Someone already submitted a patch to fix this problem here:

It’s in SVN along with a few more additions. I’m just waiting for  
Rails 1.0 so I can release aap v0.3 and piggy back on the tidal wave  
of interest.

[http://techno-weenie.net/svn/projects/plugins/acts\_as\_paranoid](http://techno-weenie.net/svn/projects/plugins/acts_as_paranoid)

Someday I’ll probably move that to RubyForge’s SVN repo too.

If you don’t plan on making any other changes before 1.0, I’d encourage  
you to release this now. It’s frustrating to spend the time tracking  
down a bug and then find out it’s been fixed previously.

Also, the SVN repository linked from the README at the URL  
[http://ar-paranoid.rubyforge.org/](http://ar-paranoid.rubyforge.org/) returns a 404.

Thanks for the plugin!

Well this was a poorly timed comment seeing as Rails went 1.0 a few  
hours after I wrote this.
