ruby - 尽管被列入白名单，但 ActiveAdmin 未经允许的参数

Question

我像这样将参数列入白名单:

permit_params(%i{identity os current_ip clients site_ids sites domains})

但我在日志中得到以下内容:

{"utf8"=>"✓", "_method"=>"patch", "authenticity_token"=>"aU8vwoMbWcMikSQLSGuVo5XTF+sAopRi0+OhgxXYvSKD9UbLaImB3k+uhf03PpWNiwtrZrEv0wVpT9pIcCkyag==", "server"=>{"identity"=>"", "os"=>"UBUNTU 14.04", "current_ip"=>"123.245.23.24", "site_ids"=>["", "1"]}, "commit"=>"Update Server", "controller"=>"admin/servers", "action"=>"update", "id"=>"1"}
  Server Load (0.2ms)  SELECT  "servers".* FROM "servers" WHERE "servers"."id" = $1 LIMIT $2  [["id", 1], ["LIMIT", 1]]
Unpermitted parameters: :site_ids

我的表格看起来像:

  form do |f|
    f.inputs "Server Details" do
      f.input :identity
      f.input :os, label: 'OS'
      f.input :current_ip, as: :string
      f.input :sites, as: :select, collection: Site.all
    end
    f.actions
  end

尽管已列入白名单，但为什么不允许使用参数？

Answer 1

site_ids 需要使用数组语法:

[:identity, :os, :current_ip, :clients, :sites, :domains, site_ids: []]

所以它会是这样的:

permit_params([:identity, :os, :current_ip, :clients, :sites, :domains, site_ids: []])
