Arrays 如何向返回的ActiveRecord查询记录添加数据

我正在对数据库表执行一个简单的查询，以发送给外部服务，但在执行此操作之前，我需要向每个返回的记录添加一个元素

app.rb

get "/:task/:account_id/contacts" do
  @contacts = Contact.where("Account = ?", params[:account_id])

  @contacts.to_json
end

提供我需要格式化为的数据

[{"Name":"Charlie Spencer","sfid":"a014100000AYi2ZABG","id":29,"Account":"a054100000FsEA8AAN"},{"Name":"Philip Leak","sfid":"a014100000AYi3PCHZ","id":48,"Account":"a054100000FsEA8AAN"}]

但在通过json发送之前，我需要将路由中提供的任务添加到结果中：

[{"Name":"Charlie Spencer","sfid":"a014100000AYi2ZABG","id":29,"Account":"a054100000FsEA8AAN","Task":"a014100000AYiWMCC1"},{"Name":"Philip Leak","sfid":"a014100000AYi3PCHZ","id":48,"Account":"a054100000FsEA8AAN","Task":"a014100000AYiWMCC1"}]

如何在发送返回的结果之前对其进行迭代？

试试这个

map

method转换结果，

attributes

method使用字段和值进行哈希，以及

merge

method添加任务

get "/:task/:account_id/contacts" do
  @contacts = Contact.where("Account = ?", params[:account_id]).map do |c|
    c.attributes.merge("Task": params[:task])
  end

  @contacts.to_json
end
