You defined a class method, then used it on an instance.  You want an
instance method, so remove self. from in front of the method
definition.

Also, you are passing a symbol instead of the actual id, so you'll
need to fix that too:

def has_items
    FormItem.count(:all, :conditions => ["form_id = ?", id])
end
