将参数传递给Rails管理中的另一个控制器

class FirstController < ApplicationController
  def some_action
    # 假设有一些逻辑处理
    @data = { key: 'value' }
    
    # 重定向到SecondController的某个动作，并传递参数
    redirect_to second_controller_path(data: @data)
  end
end

class SecondController < ApplicationController
  def another_action
    # 从查询字符串中获取参数
    @received_data = params[:data]
  end
end

class FirstController < ApplicationController
  def some_action
    @data = { key: 'value' }
    render 'second_controller/another_action', locals: { data: @data }
  end
end

# 在 app/views/second_controller/another_action.html.erb 中
<p>Data received: <%= data[:key] %></p>

class FirstController < ApplicationController
  def some_action
    # 处理逻辑
    flash[:notice] = "操作成功！"
    redirect_to second_controller_path
  end
end

class SecondController < ApplicationController
  def another_action
    # 在视图中显示flash消息
  end
end
