ruby-on-rails - Rails i18n 项目列表和循环 View

Question

如何在我的 yml 中列出元素并在 View 中遍历它们并访问它们的属性？我当前的代码只获取列表中的最后一项。我想在 View 中遍历项目列表并显示它们的 title和 description元素。

例如

yml:

en:
  hello: "Hello world"
  front_page:
    index:
      description_section:
        title: "MyTitle"
        items:
          item:
            title: "first item"
            description: "a random description"
          item:
            title: "second item"
            description: "another item description"

看法:

      <%= t('front_page.index.description_section.items')do |item| %>
          <%= item.title %>
          <%= item.description %>
      <%end %>

结果:

   {:item=>{:title=>"second item", :description=>"another item description"}} 

预期结果:

    first item
    a random description

    second item
    another item description

Answer 1

改用这个:

<% t('front_page.index.description_section.items').each do |item| %>
# ^ no equal sign here
  <%= item[:title] %>
     #^^^^ this is a hash
  <%= item[:description] %>
<% end %>

此外，您的项目列表定义不正确:

t('front_page.index.description_section.items.item.title')
# => returns "second item" because the key `item` has been overwritten

使用以下语法在 YAML 中定义数组:

items:
- title: "first item"
  description: "a random description"
- title: "second item"
  description: "another item description"

要检查这一点，您可以在 IRB 控制台中执行以下操作:

h = {:items=>[{:title=>"first item", :description=>"desc1"}, {:title=>"second item", :description=>"desc2"}]} 
puts h.to_yaml
# => returns
---
:items:
- :title: first item
  :description: desc1
- :title: second item
  :description: desc2
