I have a requirement to add a warning message similar to an error on a  
validation. The difference being that this will allow the user to  
complete the action but just display a warning message saying “You need  
to check this now…”.

The application s a loan calcualtor allowing the user to change certain  
settings to aid different calclations. Some custom validations i have  
already are below. How would i go about displaying one of them as a  
warning message, allowing the user to complete the action but dispaying  
a message? Any advice appreciated.

def validate

#Value in custom range  
errors.add(…

#Years and Months must not equal 0  
errors.add(…

#Interest Rate set for principal  
errors.add(…

end

thanks
