Thanks for your quick responses. Does I get the same id if I use @whatever.reload. if that model is accessed often and there are multiple users working on same model and I want table A id to be saved as new record in table B Table A id name email 878 Sam s...@mail.in.com
as I save 878 record in Table A I want that 878 id to be saved as new record in table B Table B id table_a_id 900 878 If in this scenario does reload helps me considering that there will me more hits to Table A by multiple users.
