I am trying to render a form within a template page with:
我试图在模板页面中呈现一个表单:
<%= form_for @vehicle, html: { class: "f_grp" }, remote: true do |f| %>

You only use :locals when you use :partial.
您只能在使用时使用:locals:partial。
Either of these are correct:
这些都是正确的:
<%= render partial: 'vehicles', locals: { f: f } %>
Or (as of Rails 2.3):
或者(从Rails 2.3开始):
<%= render 'vehicles', f: f %>
Your version, which combines both, creates a local called locals and sets its value to a hash containing f: FormBuilder....
你的版本结合了两者,创建一个本地调用的本地,并将其值设置为包含f:FormBuilder的哈希....
It's worth noting that the only reason to still use locals: is when you use render :collection.
值得注意的是,仍然使用本地的唯一原因是:当你使用render:collection时。
