Question

所以我从两个外部服务获取数据：

@list =  ExternalService.get_list
ids =  @list.map { |member| meber.id }

insurances = ExternalService2.get_insurance

# Get insurance information for each of the ids.
@coverages = insurances.map { |insurance| InsurancePresenter.new(insurance) }

/ In the view
- @list.each do |member|
  %tbody
    %tr
      %td= member.name
      %td= member.age

      / This is the part where I need to get information from the other service
      %td
        - @coverages.each |coverage|
          / method name from the presenter
          = coverage.name

很明显，我的代码的最后一部分是不正确的，因为它会打印每行的所有coverage。

我想知道是否有一种快速的方法来组合2并在应用程序中显示它们。如果是数据库请求，那将是一个简单的连接。

Answer 1

最简单的方法是为每个成员开始计数和迭代，并使用计数显示coverages数组中的每个coverage。抱歉，不知道HAML，但这是一般的想法。

/在视图中

count = -1
- @list.each do |member|
  %tbody
    %tr
      %td= member.name
      %td= member.age
      count+=1
      / This is the part where I need to get information from the other service
      %td
        - @coverages[count].name

rails在html表中组合来自2个不同来源的数据
