问题 I am creating a system that stores cards using Ruby/Rails/HAML - In this case there is a Card class that has many Colours (this is also a class). When creating and editing a card I am using the Cocoon gem to allow me to dynamically add colour associations. The problem I am having is that in the Card model, a card is limited to having a maximum of 5 colours. Yet the interface allows adding of unlimited colours resulting in an error. Is there a way in Cocoon to limit the number of associations

My problem is that I'm not able to calculate the total price for every new product added with Cocoon. Every time I enter a quantity, I get the total price from the first line. Is

问题 I've followed Cocoon's instructions for creating a nested form for a has_many association but there's one thing that I can't seem to figure out. I'm able to add an existing genre to my project but when it comes to creating a completely new one the parameters for my genres aren't being permitted. When I refer to my rails console to debug the issue this is the message I receive upon update: Unpermitted parameters: genre_attributes What's strange is I've permitted both my join table genreships
