部分在ActiveAdmin中呈现两次

Question

我的部分被渲染两次:在页面的顶部和它应该的地方.显然,只有当我有特定于ActiveAdmin的代码(table_for)时才会发生这种情况.

任何帮助是极大的赞赏.以下是我正在使用的一些代码片段.

在我的活动管理文件中:

panel "Children - SubProcesses" do
    text_node link_to "New", new_admin_sub_process_node_path(:parent_id => process_node.id)
    div render :partial => "/admin/process_nodes/child_list", :locals => { :parent => process_node }
end

在_child_list.html.erb文件中

<%=
unless parent.children.empty?
table_for parent.children do 
    column :id
    column :name
    column "Actions" do |child_node|
            text_node link_to "View", admin_process_node_path(child_node)
            text_node " "
            text_node link_to "Edit", edit_admin_process_node_path(child_node)
            text_node " "
            text_node link_to "Delete", admin_process_node_path(child_node),  :method => :delete, :confirm => "Delete?"
    end
end
end
%>

根据我的阅读,ActiveAdmin将根据当前的模型/资源名称自动获取部分路径.这意味着传递"child_list"将导致
"/admin/process_nodes/_child_list.html.erb".

用法是

div render "child_list", :locals {  :parent => process_node }

此外,似乎最好unless在ActiveAdmin面板块中包含您的语句.然后,如果没有子进程,则不必添加不必要的渲染调用.

panel "Children - SubProcesses" do
    text_node link_to "New", new_admin_sub_process_node_path(:parent_id => process_node.id)

    unless parent.children.empty?
        div render "child_list", :locals {  :parent => process_node }
    end
end

最后,我不知道是否使用偏差是一个很大的好处.我不知道你是否还有其他任何东西,但你可以这样写.

panel "Children - SubProcesses" do
  text_node link_to "New", new_admin_sub_process_node_path(:parent_id => process_node.id)

  unless parent.children.empty?
    table_for parent.children do 
      column :id
      column :name
      column "Actions" do |child_node|
        text_node link_to "View", admin_process_node_path(child_node)
        text_node " "
        text_node link_to "Edit", edit_admin_process_node_path(child_node)
        text_node " "
        text_node link_to "Delete", admin_process_node_path(child_node),  :method => :delete, :confirm => "Delete?"
        end
    end
  end
end
