Rails：Object#id 将被弃用；使用对象#object_id
可能的重复：
Rails 主键和对象 ID
非常简单的问题。我的服务器警告我第 37 行将被弃用，特别是：
#Server error:
views/projects/index.html.erb:37: warning: Object#id will be deprecated; use Object#object_id
#Views/projects/index.html.erb:
6: <% for project in @projects do %>
36: <%= project.id %>
37: <%= Matching.find_all_by_customer_id_and_project_id( @customer.id, project.id).id %>
38: <%= @customer.id %>
这是我的困惑。第 36 行 project.id 没有发出警告，因此我认为问题是我在匹配模型上调用 ID。为什么只有匹配报错，而客户或项目没有报错？如何在我的代码中纠正这个问题？
非常感谢。

Rails primary key and object id
Very quick question. My server is warning me that line 37 will be deprecated, specifically:
#Server error:
views/projects/index.html.erb:37: warning: Object#id will be deprecated; use Object#object_id
#Views/projects/index.html.erb:
6: <% for project in @projects do %>
36: <%= project.id %>
37: <%= Matching.find_all_by_customer_id_and_project_id( @customer.id, project.id).id %>
38: <%= @customer.id %>
Here's my confusion. Line 36 project.id isn't raising a warning, so I assume the issue is that I'm calling ID on the Matching model. Why is it the case that only Matching raising an error and not customer or project? How can I rectify this in my code?
Thanks very much.

@customer或您的Matching对象可能为零。nil.id是一个已弃用的方法，引用 nil 的对象 ID。在继续模板的这一部分之前，请检查您获得的
@customer和Matching对象是否包含某些内容，并且应该没问题。Either
@customeror yourMatchingobject is probably nil.nil.idis a deprecated method referring to nil's object ID.Check that both
@customerand theMatchingobject you get contain something before going ahead with this part of the template, and you should be fine.
