为什么'serialize'方法在Rails应用程序中从我的表单生成一个空数组？

Question

我在Rails应用程序中使用Simple Form Gem创建了一个包含各种输入字段的表单。其中一个问题是复选框输入字段，用户可以选择多个值，其中包含与饮食和生活方式相关的问题（你喝咖啡，吃白面包吗？等等）。在数据库中，相应的列（名为“tick”）是一个字符串输入字段。

我想做什么

我希望用户根据需要选择多个复选框，并在用户提交表单后在“显示”视图中显示这些选项。原始输出应该是一个数组，其数字对应于表单中选定的复选框。

我做了什么来实现这个

我使用了序列化方法https://apidock.com/rails/ActiveRecord/Base/serialize/class 尝试将输入保存为一个数组，该数组将在show视图中从数据库中检索。请参阅下面的模型和控制器中的实现。

究竟发生了什么

一旦用户提交表单，他们就会被重定向到“show”视图，其中相应的HTML输出只是“[]”而没有给出实际答案。请参阅下面的HTML输出：

<p>
  <strong>Pon un tic en las Casillas si son aplicables en tu caso:</strong>
  []
</p>

表格部分：_form.html.erb

<%= simple_form_for(@formulario) do |f| %>
  <%= f.error_notification %>
  <%= f.error_notification message: f.object.errors[:base].to_sentence if 
  f.object.errors[:base].present? %>
.
.
.
.
<%= f.input :tick,
    label:'Pon un tic en las Casillas si son aplicables en tu caso',
    collection: [
    ['padecido desorden alimentaria?', '1'],
    ['comes mucho lacteo o trigo?', '2'],
    ['te gusta comer/preparer comida?', '3'],
    ['compras comida ecológica?', '4'],
    ['añades sal a la comida?', '5'],
    ['tomas café o té descafeinado?', '6'],
    ['usas margarinas?', '7'],
    ['cocinas con aceites vegetales?', '8'],
    ['bebes agua filtrada?', '9'],
    ['has cambiado tu dieta ultimamente?', '10'],
    ['tomas té o café?', '11'],
    ['comes pan blanco?', '12'],
    ['comes mucho comida frita?', '13'],
    ['compras mucha comida para llevar?', '14'],
    ['comes mucha fruta y verdua fresca?  ', '15'],
    ['añades muchas salsas a la comida?', '16'],
    ['comes fuera a menudo?', '17'],
    ['cocinas para mas personas?', '18'],
    ['tienes apetito grande?', '19'],
    ['tu dieta es repetitiva?', '20'],
    ['comes pasta y arroz?', '21'],
    ['comes comida preparada?', '22'],
    ['usas el microondas?', '23'],
    ['eliges comida bajo en grasa?', '24'],
    ],
    as: :check_boxes %>
.
.
.
<% end %>

显示视图：show.html.erb

<p id="notice"><%= notice %></p>
.
.
.
<p>
  <strong>Tick:</strong>
  <%= @formulario.tick %>
</p>
.
.
.
<%= link_to 'Edit', edit_formulario_path(@formulario) %> |
<%= link_to 'Back', formularios_path %>

Formularios模型，formulario.rb

class Formulario < ApplicationRecord
  serialize :tick, Array
end

我也尝试从

更改Formulario控制器中的params散列

..., :tick, ....

到

..., tick: [], ...

以及

..., (tick: []), ...

给出了语法错误“语法错误，意外'，'，期待=＆gt;”

Formularios controller.rb

    class FormulariosController < ApplicationController

如何获取序列化方法来保存数组？或者是否有一种替代方法可以用来实现同样的目的？即记录在表格中选择了哪个复选框并在显示视图中显示它们。
