Rails：尝试将Id从控制器传递到视图(Rails : trying to pass Id from controller to view)

Rails：尝试将Id从控制器传递到视图(Rails : trying to pass Id from controller to view)

我是红宝石的小菜鸟..

我想传递我刚刚创建的对象的id来查看它将通过render方法获得渲染

这是我的代码如下

respond_to do |format| if @object.save format.html { render "finished_reg",param: @object.id ,notice: 'object was successfully created.' } #end

在视图中

<%= link_to 'Here' ,"/controller/#{:param}" %>

但没有任何事情发生..如何制作，如何在视图上打印？

i'm a little noob in ruby..

i want to pass id of object that i just created to view that it will get render via render method

this is my code below

respond_to do |format| if @object.save format.html { render "finished_reg",param: @object.id ,notice: 'object was successfully created.' } #end

in the view

<%= link_to 'Here' ,"/controller/#{:param}" %>

but nothing happen.. how to make that and how can i print this on the view?

最满意答案

从控制器到视图时， @instance_variables仍然存在。 所以你可以简单地做：

<%= link_to 'Here' ,"/controller/#{@object.id}" %>

@instance_variables persist when going from controller to views. So you can simply do:

<%= link_to 'Here' ,"/controller/#{@object.id}" %>
