How do I pass an array to fields_for in Rails?

问题 I want to use fields_for on a subset of records in an association. I have a Month model, which has_many :payments . But in my form in my view I only want to have fields_for some of those payments. For example: - fields_for @month.payments.large This doesn't work. Can I pass a set of records to fields_for , rather than the usual symbol ( fields_for :payments ) approach? 回答1: You can add additional association for large payments, for example: class Month < ActiveRecord::Base has_many :payments
