为什么部分命名为“next”不能在Ruby on Rails中工作？

In my Rails app I recently tried to use a partial named _next.html.erb which simply contains a link to the next record:

在我的Rails应用程序中，我最近尝试使用名为_next.html.erb的部分，它只包含指向下一条记录的链接：

<%= link_to_neighbor('next', @company) %>

I then tried to render that partial in my show and edit views:

然后我尝试在我的节目中渲染部分并编辑视图：

<%= render 'companies/actions/next' %>

However, that kept giving me an error which I was unable to track down:

但是，这一直给我一个我无法追查的错误：

/app/views/companies/actions/_next.html.erb:1: syntax error, unexpected '=', expecting keyword_end ..._buffer = @output_buffer;next = local_assigns[:next];;@outpu...

What really struck me was the fact that there was in fact no syntax error in the partial. The syntax is absolutely fine.

让我感到震惊的是事实上，部分中没有语法错误。语法绝对没问题。

I wasn't able to get this partial working until I renamed it from _next.html.erb to _nnnext.html.erb.

在将其从_next.html.erb重命名为_nnnext.html.erb之前，我无法进行此部分工作。

So I guess next is some kind of reserved word in Rails or Ruby?

所以我猜接下来是Rails或Ruby中的某种保留字？

According to this list it's not, though!

根据这个清单，它不是，但是！

Any ideas?

有任何想法吗？

next is a Ruby keyword. Add all such keywords to the list of things you shouldn't name partials in Rails.

next是Ruby关键字。将所有这些关键字添加到不应在Rails中命名为partials的事项列表中。

Because of RoR's wonderful "configuration by convention", all partials get a local variable named after the partial, containing its payload. So to run your partial, Rails evaluated next = local_assigns[:next] But the next on the left looks like a keyword, so >kaboom!<

由于RoR的精彩“按惯例配置”，所有部分都获得一个以partial为名的局部变量，包含其有效负载。所以要运行你的部分，Rails评估next = local_assigns [：next]但是左边的下一个看起来像一个关键字，所以> kaboom！<
