Can we use different field name than the database column name in cakephp2?

For example:
The database has user_name, email, pass, etc.
now I want to use this in Form with the name like
user_name as name ,
email as email
pass as password

Can anyone help me for this, It is Cakephp 2

Are you speaking about the actual field name of the label?
You can apply any label to a form field: http://book.cakephp.org/3.0/en/views/helpers/form.html#options
Why would you want to change to actual name of the field since this is invisible to the user?
