Question

我是rails的新手，我正在尝试自定义ActiveAdmin。我的应用程序有3个型号：用户（有很多产品），产品（有很多价格）和价格。我正在尝试使用嵌套表单自定义ActiveAdmin，以便能够直接使用其价格创建/更新产品。虽然更新工作完美（更新产品甚至添加新价格），但创建操作不起作用。我在控制台中得到“回滚”但没有特定的错误消息。你能告诉我我做错了什么吗？

# app/admin/products.rb
ActiveAdmin.register Product do
  form do |f|
    f.semantic_errors
    f.inputs do
      f.input :name
      f.input :size
    end
    f.inputs "Prices" do
      f.has_many :prices do |price|
        price.input :value
        price.input :currency, :collection => ["dollars", "euros", "pounds"]
      end
    end
  f.actions
end
permit_params :name, :size, :user_id, prices_attributes: [:id, :currency, :value, :product_id, :_edit, :_update, :_new, :_create]

我还在app / models / product.rb中添加了“accepts_nested_attributes_for：prices”。

日志构成了控制台
