In rails3 this is what I get.

validates\_presence\_of :subject  
#=\> subject can’t be blank

validates\_presence\_of :subject, :message =\> “can’t be empty”  
#=\> subject can’t be empty

However What I want is  
#=\> Please enter title  
even though the field name is “subject”.

How do I do that in rails3?

I haven’t played around with it, but object.errors[attribute] \<\<  
error\_message should probably be changed to just error\_message.

Let me know how it goes.

validates :subject , :presence =\> “Greetings sire, please introduce the  
title!”

am not sure if you need to put { }
