I have this code in rp_parts controller in def destroy:
@repair_ticket.rp_parts.delete(@rp_part)
repair_tickets and rp_parts are HABTM.
If I do in the console:
repair_ticket1.rp_parts
I get:
=> [#<RpPart id: 1, …">, #<RpPart id: 1,…">, #<RpPart …">]
I only want to delete one of those RpPart id:1, and not both of them. Is
it possible?
