ruby-on-rails - 在Rails中使用Bootstrap格式化复选框形成erb？

问题描述

我在 Rails 视图表单中使用了多个复选框。我正在使用 Bootstrap 4 进行样式设置。如果复选框有 Bootstrap 样式，例如：

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <div class="input-group-text">
      <input type="checkbox" aria-label="Checkbox for following text input">
    </div>
  </div>
  <input type="text" class="form-control" aria-label="Text input with checkbox">
</div>

<div class="input-group">
  <div class="input-group-prepend">
    <div class="input-group-text">
      <input type="radio" aria-label="Radio button for following text input">
    </div>
  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

如何在 erb 对象中实现多个类样式？这是我要实现的代码：

            <%= f.collection_check_boxes(:authorization_ids, Authorization.all, :id, :auth_name, { checked: @account.try { |a| a.authorization_ids.map(&:to_param) } }, multiple: true, # WOULD LIKE TO IMPLEMENT BOOTSTRAP CLASSES HERE ) %>
        <%= f.label :authorization_ids, 'Authorizations' %>

更新

这里有一些很棒的回应。我最终使用bootstrap_form_with了 rails_bootstrap_formGem。我使用自定义包装类进行样式设置，并且能够在有序的列和行中获取复选框。

<div class="container">
    <div class="col">
        <div class="row justify-content-center">
            <div class='form-group'>
                <%= bootstrap_form_with(model: @account) do |f| %>
                <%= f.text_field :account_name %>
                <%= f.text_field :account_address_line1 %>
                <%= f.text_field :account_address_line2 %>
                <%= f.text_field :account_city %>
                <%= f.select :account_state, states %>
                <%= f.text_field :account_zipcode %>
                <%= f.text_field :contact_first_name %>
                <%= f.text_field :contact_last_name %>
                <%= f.email_field :contact_email %>
                <%= f.telephone_field :contact_phone %>
                <%= f.select :account_ppu, ppu, placeholder: "Select PPU...." %>
                <%= f.text_area :account_notes %>
            </div>

            <%= f.collection_check_boxes :authorization_ids, Authorization.all, :id, :auth_name, hide_label: true, wrapper: {class: "cp-container-class"} %>
        </div>
        <%= f.submit 'Create' %>
        <% end %>
    </div>
</div>

造型：

@import "bootstrap";
 @import "rails_bootstrap_forms";
 @import url('https://fonts.googleapis.com/css?family=Baloo+Thambi+2|Lato&display=swap');

 body {
     margin: 0px;
 }


#logo {
     margin: 1em;
     padding: 1em;
     width: 500px;
     height: auto;

 }

 .cp-container-class {
     width: 1000px;
     height: 500px;
     justify-items: center; 
    flex-direction:column;
      padding: 10px;
     /* Change to whatever*/
     display: flex;
     flex-wrap: wrap;
     border: black 1px solid;
 }

 .cp-container-class>* {
     flex: 1 1 20px; 
     margin-left: 50px; 
     letter-spacing: 5px;

 }

解决方案

根据的文档，collection_check_boxes您可以使用构建器添加 HTML 类，如下所示：

collection_check_boxes(:post, :author_ids, Author.all, :id, :name_with_initial) do |b|
  b.label(class: "check_box") { b.check_box(class: "check_box") }
end

就您的情况而言，它看起来像这样：

collection_check_boxes(:authorization_ids, Authorization.all, :id, :auth_name, { checked: @account.try { |a| a.authorization_ids.map(&:to_param) } }, multiple: true) do |b|
  b.label(class: "some-class another-class") { b.check_box(class: "a-class a-different-class") }
end

这可能不是您想要的。你可能不得不玩一下它。
