How can I fix the following code for deprecation warning?

def correct\_client\_assignment  
role = Role.find\_by\_name(‘eclient’)  
if client\_id.blank? && role\_id == role.id  
errors.add :client\_id, “must assign an external client to this  
user”  
elsif !client\_id.blank? && role\_id != role.id  
errors.add :client\_id, “cannot assign an internal user to a  
client”  
end  
end

It is the errors.add part that is triggering the following messages:

…DEPRECATION WARNING: Errors#on have been  
deprecated, use Errors#[] instead.  
Also note that the behaviour of Errors#[] has changed. Errors#[] now  
always returns an Array. An empty Array is returned when there are no  
errors on the specified attribute. (called from on at  
/home/bruparel/.rvm/gems/ruby-1.9.2-p0/gems/activemodel-3.0.0.rc2/lib/active\_model/deprecated\_error\_methods.rb:7)

Thanks.
