hi everyone here i go again, i have problem we error message validation  
here is the sample of my code:

error\_messages\_for :user, :header\_message =\> ‘X errors, please find red  
mark’, :message =\> ‘Following errors were found:’

the problem is that how where going to get the value “X errors” or the  
number of errors if they have when the is submitted.

I like the idea of the default error message that have a counter of  
errors like for example “2 errors prohibited this user from being  
saved”. My purpose is to make my own error message but the idea of  
displaying the number of errors is my problem. Please help me on how to  
do it. Thank you in advance…

“#{User.errors.size} errors, please …”

@user.errors.full\_messages

that will return an array of the text messages. So you can do  
@user.errors.full\_messages.size and then iterate on them to create  
your own error message.
