Ruby on rails 活动管理表单仅显示“”

我正在积极管理HABTM关系。我有两个模型：magazine.rb和keyword.rb，它们都通过联接表magazies\u keyword.rb进行关联。我想能够选择在活动管理关键字从杂志资源页

AA资源文件magages.rb如下所示：

ActiveAdmin.register Magazine do
menu :priority => 1

form do |f|
    f.semantic_errors *f.object.errors.keys
    f.inputs "Magazine Details" do
        f.input :title_id, :label => 'Title', :as => :select, :collection => Keyword.all.map{ |u| ["#{u.word.capitalize}", u.id] }
        f.input :keywords, :as => :check_boxes, :input_html => { :multiple => true } do
            f.has_many :keywords do |s|
                s.input :keyword, :collection => Keyword.all.map { |kw| ["#{kw.word.capitalize}", kw.id] }
            end
        end
    end
    f.actions
end

show do
    panel "Magazine Details" do
        attributes_table_for magazine do
            row "Keywords", :keyword do |m|
                m.keywords.map { |d| d.word }.join(", ").html_safe
            end
        end
    end
    active_admin_comments
end

表演部分起作用了。通过此设置，我还可以输入一个新的杂志，并写入联接表，但表单不显示关键字，只显示关键字。哪个是什么？该字段的活动记录地址

如何让表单为每条记录显示正确的数据条目

当我使用：

f.input :keywords, :as => :check_boxes, :input_html => { :multiple => true }, :collection => Keyword.all.map { |kw| ["#{kw.word.capitalize}", kw.id] }

将显示关键字，但联接表似乎不起作用，因为我无法读取、编辑或写入新条目或现有条目

我怎样才能让这个部件工作

更新

当我使用创建新的杂志条目时

f、 输入：关键字，：as=>：复选框

以及：

f.input :keywords, :as => :check_boxes, :input_html => { :multiple => true } do
    f.has_many :keywords do |s|
        s.input :keyword, :collection => Keyword.all.map { |kw| ["#{kw.word.capitalize}", kw.id] }
    end
end

我得到：

我认为您需要使用：

f.input :keywords, as: :check_boxes, member_label: :word

或

尝试只保留f.input:keywords，：as=>：复选框，并删除其余包含嵌套输入的复选框谢谢您的输入。我试过了，但它输出了相同的奇怪字符串活动记录键：value？？？。我最终得到了一个嵌套输入，因为我认为我必须用keyword.word之类的东西来获取关键字。我被困在这里了。你在magazies.rb的许可证部分有什么？当您使用f.input:keywords，：as=>：check_box，：input\u html=>{：multiple=>true}，：collection=>Keyword.all.map{{kw |[{kw.word.capitalize}，kw.id]}并尝试向杂志添加一些关键字时，服务器日志中是否有一些不允许的参数？f.input:keywords，as:：check_box，member\u label:：wordf.input:keywords，as：：复选框，成员标签：Proc.new{kw{kw.word.capitalize}

f.input :keywords, as: :check_boxes, member_label: :word

f.input :keywords, as: :check_boxes, member_label: Proc.new { |kw| kw.word.capitalize }
