ActiveAdmin具有has_many问题;未定义的方法“ new_record?”
我正在尝试为与Step具有has_many关系的配方模型自定义ActiveAdmin表单。 class Recipe < ActiveRecord::Base has_many :steps end class Step < ActiveRecord::Base acts_as_list :scope => :recipe belongs_to :recipe end 我在ActiveAdmin文件中有以下与此相关的内容: form do |f| f.has_many :steps do |ing_f| ing_f.inputs end end 当我尝试加载表单时引发以下错误: 未定义的方法“ new_record?” 对于nil:NilClass 到目前为止,我已经将它隔离到has_many方法,但是我迷失了它。任何建议和帮助,将不胜感激!
