In my Mongrel logs, I am getting this:

…active\_record/validations.rb:81: warning: Object#type is deprecated;  
use Object#class

That piece of code is:

```
def add_on_blank(attributes, msg = @@default_error_messages[:blank])
  for attr in [attributes].flatten
    value = @base.respond_to?(attr.to_s) ? @base.send(attr.to_s) :

```

@base[attr.to\_s] \<\<\< line 81  
add(attr, msg) if value.blank?  
end  
end

I don’t see what Ruby is complaining about. Anyone have any ideas?

Thanks,  
pedz

just a guess, but have you given any of your models a “type” field in  
the database? rails by default will think that your model is using  
STI if you have a “type” field.

Thanks but, no… I don’t see just a “type” field. I looked in my  
migrate files and then I did a rake db:schema:dump and looked in the  
dump file. I have things like “item\_type” but not just “type”.

I’m using edge rails – if that matters.

I might have found it. I use to have a field “type” but I changed it.  
But I goofed and did not change my “validates\_presence\_of :type”.

I bet thats it.

Thanks.

aha… you should have caught that in your unit tests 😉
