Validate_presence_of - not always needed

Rails
1

hey,
I do some validation in my user.rb file when a user signing up
validates_presence_of :password

now, when the user want to edit its account, I dont want that the
password is checked anymore - how can I do that?

I need the validation only in the signup process but not in the account
editing process?

If you only want to validate when the record is first created, you can
add:

:on => :create

to your helper, like this:

validates_presence_of :password, :on => :create

On subsequent record updates that validation will not be called.
