我目前正在尝试呈现一个带有错误消息的分部，如果表单提交无法创建tenant示例。我使用Rails文档中描述的locals将变量传递给分部。
控制器/租户_控制器.rb

def new
    @unit = Unit.find(params[:unit_id])
    @tenant = Tenant.new
  end

  def create
    @unit = Unit.find(params[:unit_id])
    @tenant = @unit.tenants.new(tenant_params)

    if @tenant.save
      redirect_to @tenant
    else
      Rails.logger.error('Unable to save Tenant')
      render 'new'
    end
  end

在这里，如果@tenant创建失败，我将重定向到new模板。这应该会向@tenant添加错误

此处，im通过locals传递tenant变量，但它似乎没有将变量传递给<%= render 'errors', locals: { tenant: f.object } %>行中的部分错误
当呈现错误部分时，将引发错误。tenants/_errors.html.erb

<% if tenant.errors.any? %>
<div class="rounded-md bg-red-50 p-4">

知道为什么吗
未定义#〈ActionView：：Base的局部变量或方法'tenant'
正在被提升？
