Have you tried just setting @user.password and  
@user.password\_confirmation (or equivalent) before the @user.save  
part?

Thank you, i can fix it now.  
i have to put

= f.hidden\_field :password,:value=\>“”  
= f.hidden\_field :password\_confirmation,:value=\>“”

in form first and then i can type

@user.password=@user.password\_confirmation=random\_password in controller  
before save
