简单形式不加 bootstrap 类

Question

我创建了一个新的 Rails 项目，将 gem 'simple_form', '~> 3.2', '>= 3.2.1' 添加到我的 gem 文件并将我的项目配置为使用 Bower，而不是通过 Bower 添加 Bootstrap。

即使我使用了 rails generate simple_form:install --bootstrap，表单元素也没有得到 Bootstrap css 类.

我在页面呈现后检查了 HTML 并且 Bootstrap css/js 在那里。我需要使用 Bootstrap gem 而不是 Bower 包吗？？

这是 .bowerrc 文件：

{
  "directory": "vendor/assets/components"
}

bower.json

{
  "name": "TesteKlipbox",
  "authors": [
    "Juliano Nunes"
  ],
  "description": "",
  "main": "",
  "license": "MIT",
  "homepage": "",
  "private": true,
  "ignore": [
    "**/.*",
    "node_modules",
    "bower_components",
    "vendor/assets/components",
    "test",
    "tests"
  ],
  "dependencies": {
    "bootstrap": "^3.3.6"
  }
}

更新

另一个用户已经回答了这个问题。我的错误是我没有用 f.input 替换 f.text_field。它与建议的 bootstrap 主题问题无关。

Answer 1

确保 bootstrap 存储在正确的位置：

bootstrap.min.css 以及 bootstrap.css,

bootstrap.min.js 和 bootstrap.js,

都需要分别位于app/assets/stylesheets和app/assets/javascripts。

将 *= require bootstrap 添加到 app/assets/stylesheets/application.css 并且，

将 //= require bootstrap 添加到 app/assets/javascripts/application.js

Answer 2

To start using Simple Form you just have to use the helper it provides:

<%= simple_form_for @user do |f| %>
  <%= f.input :username %>
  <%= f.input :password %>
  <%= f.button :submit %>
<% end %>

助手是 f.input 而不是 Rails 助手，例如 f.text_field、f.text_area 等。参见 Simple_Form Usage and Rails Form Helpers。

下图显示第一个输入使用 f.text_field，第二个使用 f.input。
