Rails Form Builder-如何放置html屬性

Question

我有一個server_form迭代，我在其中放置了class: 'form-control'它工作正常，除了使用|spec_fields|的最后一次迭代之外

= 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}
    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：如何將form-control類也放入|spec_fields|

Answer 1

從文檔中，您必須將其傳遞到塊之前，以便...

= 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}

應該管用

Answer 2

在fields_for塊之外執行fields_for ：

= 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' }
