strong-parameters

问题 I'm trying to create an event app where each event has multiple tables and each table has multiple people sitting at a table the event has multiple tickets which map the people to the tables that they are sitting at -> in order to achieve this I have created a checkbox nested in the fields_for :tables (which is in turn in the event form) I presume something is wrong with either the strong parameters or the form itself but I have not been able to find any information that provides a solution
