Has Many through with simpleform
问题 I'm struggling to get going with a simpleform field for a hasmany through association. When i submit the form the has_many records are not saved, and if the form doesn't validate the options are not selected when the form redisplays. so in short, nothing is working. I'm not sure how much automagic should be going on here, or if I am just missing code i need to make it work. I don't think it's a strong parameters issue as I am not getting a permit params error in the logs. model class Coupon <
