Jquery formvalidation.io-工具提示不起作用

我正在尝试使用rails应用程序设置formvalidation。我不明白为什么工具提示中没有显示错误消息。我看了好几遍formvalidation文档，它看起来是正确的。我很难解决这个问题。我在vendor/assets/javascripts中有

formValidation.min.js和
bootstrap.min.js
（formValidation版本）。我在供应商/资产/样式表中有
formValidation.min.css

application.js

//= require jquery
//= require jquery.turbolinks
//= require jquery_ujs
//= require formValidation.min.js
//= require bootstrap.min.js
//= require bootstrap-sprockets
//= require bootstrap-select.min
//= require bootstrap-typeahead-rails
//= require turbolinks
//= require fancybox
//= require_tree .

$(document).ready(function() {
$('#custom-tag').formValidation({
    framework: 'bootstrap',
    err: {
      container: 'tooltip'
    },
    icon: {               
      valid: null,
      invalid: null,
      validating: null
    },
    fields: {
      tag: {
        validators: {
          stringLength: {
            min: 3,
            max: 10,
            message: 'Must be between 3 and 10'
          }
        }
      }
    }
  });
});
