Hello ,

validating following fields

validates\_presence\_of :email

/(^([^@\s]+)@((?:[-\_a-z0-9]+.)+[a-z]{2,})$)|(^$)/i  
validates\_uniqueness\_of :email  
validates\_presence\_of :password, :on =\> :create  
validates\_length\_of :password, :in =\> 4…20, :allow\_nil =\> false,:on  
=\> :create  
validates\_presence\_of:password\_confirmation, :if =\>  
:password\_required?  
validates\_confirmation\_of :password, :if =\> :password\_required?  
validates\_presence\_of :first\_name  
validates\_presence\_of :last\_name  
validates\_presence\_of :address

Hello, is it because of :on =\> :create? maybe you could change it to  
default
