I study RailSpace code and the line code in the book

@error\_messages = ActiveRecord::Errors.default\_error\_messages

has been deprecated. Instead the following is recommended

@error\_messages = I18n.translate(‘activerecord.errors.messages’)

But the line  
correct\_error\_message = sprintf(@error\_messages[:too\_short],  
:count=\>min\_length)

does not assign the value min\_length to {{count}} part of  
@error\_messages[:too\_short] “is too short (minimum is {{count}}  
characters)” .

I do not know how to set the min\_length value to {{count}} in  
error\_messages[:too\_short].

Thanks.
