Ruby on rails Formtastic以嵌套形式打印数字

我有这张表格

- semantic_form_for :qualification,  :url => { :controller => 'qualifications', :action => 'add_students' } do |form|
- form.inputs do
  = form.input :name, :label => "Course Title"
  = form.input :course_type, :collection => Qualification::COURSE_TYPES
  = form.input :graduate_date, :label => "Course Start Date", :start_year => pdc_start_year, :end_year => 1972, :discard_day => true
  = form.input :location, :label => "Course Location"
  = form.semantic_fields_for :user do |student|
    = student.input :first_name
    = student.input :last_name
= form.submit 'Add Students'

它在这个按钮之前创建

1.

我看到生成了这个1，但我想删除它

只是猜测您正在使用rails 2

= form.semantic_fields_for :user do |student|

应该是

- form.semantic_fields_for :user do |student|
