Rails的表單生成器 - 怎樣把HTML屬性

我有一個server_form迭代這裏我把class: 'form-control' 它工作正常，除了最後一次迭代與|spec_fields|Rails的表單生成器 - 怎樣把HTML屬性

= form_for @server do |server_form| 
    = server_form.label :hostname 
    = server_form.text_field :hostname, class: 'form-control' 

    = server_form.label :description 
    = server_form.text_field :description, class: 'form-control' 

    = server_form.fields_for :spec do |spec_fields| 
    Count of CPUs : #{spec_fields.text_field :cpucount} 
    RAM (GB): #{spec_fields.text_field :ram_gb} 
    HD (GB): #{spec_fields.text_field :hd_gb} 
    HD used (GB): #{spec_fields.text_field :hdused_gb}

我的問題是：我怎樣才能把form-control類也爲|spec_fields|

當你做到這一點fields_for塊之外：

= form_for @server do |server_form| 
    = server_form.label  :hostname 
    = server_form.text_field :hostname, class: 'form-control' 
    = server_form.label  :description 
    = server_form.text_field :description, class: 'form-control' 

    = server_form.fields_for :spec do |spec_fields| 
    Count of CPUs : #{ spec_fields.text_field :cpucount, class: 'form-control' } 
    RAM (GB):  #{ spec_fields.text_field :ram_gb, class: 'form-control' } 
    HD (GB):   #{ spec_fields.text_field :hd_gb,  class: 'form-control' } 
    HD used (GB): #{ spec_fields.text_field :hdused_gb, class: 'form-control' }

從docs你必須在它傳遞塊，前...

= server_form.fields_for :spec, class: 'form-control' do |spec_fields| 
    Count of CPUs : #{spec_fields.text_field :cpucount} 
    RAM (GB): #{spec_fields.text_field :ram_gb} 
    HD (GB): #{spec_fields.text_field :hd_gb} 
    HD used (GB): #{spec_fields.text_field :hdused_gb}

應該工作
