activeadmin的has_many隐藏删除按钮

Question

我得通过相关联的的has_many如下：

class Room < ApplicationRecord 
    has_many :room_options 
    has_many :options, through: :room_options 

    accepts_nested_attributes_for :room_options, allow_destroy: false 
end 

class RoomOption < ApplicationRecord 
    belongs_to :room 
    belongs_to :option 
end 

class Option < ApplicationRecord 
    has_many :room_options 
    has_many :rooms, through: :room_options 
end 

和activeadmin页：

ActiveAdmin.register Room do 
    permit_params :name, :guests_capacity, :description, :price, photos_attributes: [:id, :image, :is_primary, :_destroy] 

    form(:html => { :multipart => true }) do |f| 
    f.inputs do 
     f.input :name 
     f.input :guests_capacity 
     f.input :description 
     f.has_many :photos, allow_destroy: true do |photo| 
     photo.input :image, as: :file, 
     hint: image_tag(photo.object.image_url(:thumb)) 
     photo.input :is_primary 
     end 

     Option.find_each { |option| f.object.room_options.build(option: option)} 

     f.has_many :room_options, new_record: false, allow_destroy: false do |rof| 
     rof.input :option_id, as: :hidden 
     rof.input :has_option, as: :boolean, label: rof.object.option.name 
     end 

     f.input :price 
    end 
    f.actions 
    end 

end 

我想删除从f.has_many '删除按钮'，但我似乎无法使其工作。我使用了allow_destroy: false，但即使将其添加到accepts_nested_resources也不起作用。有谁知道如何使它工作？

奇怪

从它看起来像不包括:allow_destroy的文件是不具有破坏选项的解决方案

ActiveAdmin.register Post do 

    form do |f| 
    f.inputs 'Details' do 
     f.input :title 
     f.input :published_at, label: 'Publish Post At' 
    end 
    f.inputs 'Content', :body 
    f.inputs do 
     f.has_many :categories, heading: 'Themes', 
           allow_destroy: true, 
           new_record: false do |a| 
     a.input :title 
     end 
    end 
    f.inputs do 
     f.has_many :taggings, sortable: :position, sortable_start: 1 do |t| 
     t.input :tag 
     end 
    end 
    f.inputs do 
     f.has_many :comment, 
       new_record: 'Leave Comment', 
       allow_destroy: -> { |c| c.author?(current_admin_user) } do |b| 
     b.input :body 
     end 
    end 
    f.actions 
    end 

end 

的：allow_destroy选项增加一个复选框，嵌套结束形式允许在提交时移除儿童物体。请务必在关联上设置allow_destroy：true以使用此选项。可以将：allow_destroy与一个字符串或符号相关联，对应于将被调用的子对象方法的名称，或与Proc对象相关联。 Proc对象将该子对象作为参数接收，并返回true或false。

也in some cases包括accepts_nested_attributes_for :images, allow_destroy: true包括此选项

我不知道如何解决这个问题，也许你应该在自己的GitHub页面发布一个问题是必要的吗？
