Rails - Apr 2006 - Preventing data being written to the database on error

Hello,

How do I stop data being written to the database when an error occurs?

I have this in my controller:

if @item.valid?
    #stuff here
else
    render :action => ''show'', :id => @item
end

When it enters the else section, it renders the ''show'' action,
but it
adds the data to the database. How do I prevent this from happening?

Thanks

Well, if your @item isn''t valid, it shouldn''t be successfully
saved.
There''s something funny going on otherwise.

Your example doesn''t show where your save method is getting saved, or
if
there''s some data manpulation -- or even what your validation consists
of.
Knowing that stuff would help quite a bit.
