当使用Rails ActiveAdmin gem显示资源时,我想显示另一个关联模型的表.
所以让我们说一个酒庄has_many:产品.现在我想显示与Winery管理员资源的显示页面相关联的产品.而且我希望这是一个类似于产品资源索引的表格.
我得到它的工作,但只有通过手动重新创建HTML结构,哪种吮吸.为相关资源的特定子集创建索引表样式视图是否有更清洁的方法?
我有什么,有点吸吮:
show title: :name do |winery| attributes_table do row :name row(:region) { |o| o.region.name } rows :primary_contact,:description end # This is the part that sucks. div class: 'panel' do h3 'Products' div class: 'attributes_table' do table do tr do th 'Name' th 'Vintage' th 'Varietal' end winery.products.each do |product| tr do td link_to product.name,admin_product_path(product) td product.vintage td product.varietal.name end end end end end end
解决方法
为了解决这个问题,我们使用了partials:
/app/admin/wineries.rb
ActiveAdmin.register Winery do show title: :name do render "show",context: self end end
应用程序/管理/ products.rb
ActiveAdmin.register Product do belongs_to :winery index do render "index",context: self end end
/app/views/admin/wineries/_show.builder
context.instance_eval do attributes_table do row :name row :region row :primary_contact end render "admin/products/index",products: winery.products,context: self active_admin_comments end
/app/views/admin/products/_index.builder
context.instance_eval do table_for(invoices,:sortable => true,:class => 'index_table') do column :name column :vintage column :varietal default_actions rescue nil # test for responds_to? does not work. end end
