ruby-on-rails-5 - 将变量传递给方法 info_for_paper_trail

问题描述

在表版本中，我创建了新列 'localip' 。在视图中，我有通过 JS 放置价值的隐藏字段：

<%= f.hidden_field :localIP, :value => params[:localIP] %>

如果我理解正确，则首先调用 paper_trail，因此我将其放入控制器中：

  prepend_before_action :set_localip, only: :update   

  def info_for_paper_trail
     { 
       :ip => request.remote_ip, 
       :agent => request.user_agent,
       :localip => @localip
      }
  end

private
    def set_localip
       @localip = params[:localIP] 
    end

但在更新期间：localip 未通过：

PaperTrail::Version Create (0.3ms) INSERT INTO "versions" ("item_type", "item_id", "event", "whodunnit", "object", "created_at", "object_changes", "ip", "agent") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)

有人知道如何传递这样的价值吗？

解决方案

解决了：

在控制器中：

  prepend_before_action :set_localip, only: :update   
  before_action :set_paper_trail_whodunnit, if: :user_signed_in?

  def info_for_paper_trail
     { 
       :ip => request.remote_ip, 
       :agent => request.user_agent,
       :localip => @localip
      }
  end#

private
    def set_localip
       @localip = params.require(:commission)[:localIP]
    end

/config/initializers/paper_trail.rb

module PaperTrail
  class Version < ::ActiveRecord::Base
     belongs_to :user, foreign_key: :whodunnit
  end
end
