For <element>_tagyou specify HTML attributes directly, as follows:
对于<element>_tag您直接指定 HTML 属性，如下所示：
<% form_tag session_path, :id => 'elm_id', :class => 'elm_class',
:style => 'elm_style' do -%>
...
<% end -%>
It is for <element>_remote_tagconstructs that you need to move the HTML attributes inside a :htmlmap:
对于需要在地图内移动 HTML 属性的构造：<element>_remote_tag:html
<% form_tag form_remote_tag :url => session_path, :html => {
:id => 'elm_id', :class => 'elm_class',
:style => 'elm_style' } do -%>
...
<% end -%>

This code
这段代码
form_tag(:controller => "people", :action => "search", :method => "get", :class => "nifty_form")
give as result:
给出结果：
<form accept-charset="UTF-8" action="/people/search?method=get&class=nifty_form" method="post">
But, if you use this structure
但是，如果你使用这个结构
form_tag({:controller => "people", :action => "search"}, :method => "get", :class => "nifty_form")
you will get as result
你会得到结果
<form accept-charset="UTF-8" action="/people/search" method="get" class="nifty_form">
and it's exactly what you want
这正是你想要的

就我而言，我需要将 HTML 选项放入{}实际添加id到form_tag，如下所示：
<%= form_tag(some_update_path(@some_record), { method: :put, id: "some-id" }) do
<% end %>
<%= form_tag(some_update_path(@some_record), { method: :put, id: "some-id" }) do
<% end %>
