ruby-on-rails – SimpleForm ClientSideValidations bootstrap

我在RoR应用程序中使用SimpleForm,ClientSideValidations和ClientSideValidations-SimpleForm gems.我可以将表单精美地渲染到模态中,但是当输入失去焦点时,不会进行验证并提交表单.另请注意,我已尝试使用此处找到的修复程序：

包含表单的视图的片段：

<div class='modal hide' id='New_Discrep' tabindex="-1" role='dialog' aria-labelledby="#New_Discrep_Label" aria-hidden='true'>
  <div class="modal-header">
    <button type='button' class='close' data-dismiss='modal' aria-    hidden='true'>x</button>
    <h3 id="New_Discrep_Label">Create Discrepancy</h3>
  </div>
  <%= simple_form_for @new_discrepancy,:validate => true,:url => {:controller=> 'discrepancy',:action => 'create',:device_id => @device.id} do |f| %>
  <div class='modal-body'>
    <%= f.input :system,:wrapper => :prepend,:label => false do %>
      <%= content_tag :span,'System',:class => 'add-on input-label' %>
      <%= f.input_field :system %>
    <% end %>
    <%= f.input :description,'Description',:class => 'add-on input-label' %>
      <%= f.input_field :description,:class => 'textarea' %>
    <% end %>
    <%= f.input :conditions,'Condiditions',:class => 'add-on input-label' %>
      <%= f.input_field :conditions,:class => 'textarea' %>
    <% end %>
    <%= f.input :dirf,'Reference',:class => 'add-on input-label' %>
      <%= f.input_field :dirf %>
    <% end %>
  </div>
  <div class='modal-footer'>
    <button type="button" class='btn',data-dismiss='modal',aria-hidden='true'>Cancel</button>
    <%= f.button :submit,:class => 'btn-primary' %>
  </div>
  <% end %>
</div>

我的Gemfile

gem 'rails','3.2.1'
gem 'jquery-rails'
gem 'carrierwave'
gem 'simple_form'
gem 'client_side_validations'
gem 'client_side_validations-simple_form'

模型

class Discrepancy < ActiveRecord::Base
STATUSES = ['Open','Closed','Rejected']

  belongs_to :device
  belongs_to :user
  has_many :parts
  has_many :updates

  validates :date_entered,:presence => true
  validates :status,:presence => true
  validates :description,:presence => true
  validates :system,:presence => true
  validate :close_date

  validates_inclusion_of :status,:in => STATUSES,:message => "must be one of: #{STATUSES.join(',')}"  

end

application.js文件

//= require jquery
//= require jquery_ujs
//= require rails.validations
//= require rails.validations.simple_form
//= require_tree .

我还确认脚本标签是在表格正下方的html中生成的.
谢谢您的帮助！

$('#myModal').on('shown',function () {
  $(ClientSideValidations.selectors.forms).validate();
});
