New password could not set into DB using Ruby on Rails 3

I am trying to reset the new password using Rails 3.When i insert new password(i.e.123456789) and clicked on submit button it gave me the following error.

Error:

NoMethodError in HomesController#resubmitpass

undefined method `stringify_keys' for "123456789":String
Rails.root: C:/Site/library_management1

Application Trace | Framework Trace | Full Trace
