ruby-on-rails – 35的未定义方法`merge’：Fixnum

不要使用<％= f.hidden_??field：field,number％>,使用<％= f.hidden_??field：field,value：number％>

问题如下

An ActionView::Template::Error occurred in bookings#new:

 undefined method `merge' for 35:Fixnum
 app/views/bookings/_form.html.erb:31:in `block in _app_views_bookings__form_html_erb__2731573742378725623_70113682151640'

从我们的生产网站获得这个可怕的一般错误,并不清楚为什么.它不会发生在我们当地的主机上.这是上面引用的行：

<%= current_employer.locations.first.name_or_address_1 %>

其中name_or_address_1是：

return "from #{name}" if name.present?
"from #{address_1}"

我已进入控制台并为我们数据库中的每个位置运行“name_or_address_1”,这可以正常工作,并为我们数据库中的每个雇主运行“locations.first.name_or_address_1”.再次,工作正常.那么肯定不是这一行吗？

编辑：我刚刚注释掉了部署到生产线,然后仍然出现错误.这是怎么回事？为什么引用错误的行？

这是部分：

<%= form_for @employer,url: bookings_path,method: :post,html: { class: "main-form",id: "create-booking" } do |f| -%>
  <% @employer.errors.full_messages.each do |msg| %>
