ruby on rails - Pre-populate record with values from previous record -

When a user goes into a new action, I want to prepare those values ​​with values ​​from their last record. These can be changed if desired and used to create a new record.

I am convinced that in the new action of my controller, I can get the most recent record (using something like this).

I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page.
