Rails 4、Bootstrap 3、simple_form - 表单样式不起作用 [英] Rails 4, Bootstrap 3, simple_form - form styling not working

问题描述

过去我曾使用 rails 3.x bootstrap 2.x 和 simple_form 取得了巨大的成功.但是，我尝试创建一个新的(未升级的)Rails 4/Bootstrap 3 应用程序，虽然可以使用 simple_form 语法，甚至可以使用嵌套表单，但看起来样式不起作用.我在非基于模型的表单上使用了 rails-bootstrap-forms 并且样式看起来不错，但是，我更愿意将 simple_form 用于我的大多数表单.

我的文件如下所示

/**= require_self*= 需要 rails_bootstrap_forms*= 需要字体很棒*= require_tree .*/@import "bootstrap-sprockets";@import "引导程序";

我有两个未更改的初始化程序 simple_form.rb 和 simple_form_bootstrap.rb

和如下所示的表单

<%= simple_form_for @item, :html =>{ :class =>'form-horizo​​ntal' } 做 |f|％＞<% if f.error_notification %><div class="alert 警报-错误淡入"><a class="close" data-dismiss="alert" href="#">&times;</a><%= f.error_notification %>

<%结束%><%= f.input :user_id, :as =>:隐藏, :input_html =>{:值=>@userid } %><%= f.association :category %><%= f.input :name %><%= f.input :description %><%= f.input :cool %><%= f.input :cold %><%= f.button :submit, :class =>'btn-主要'%><%= link_to t('.cancel', :default => t("helpers.links.cancel")),items_path, :class =>'btn btn-默认' %><%结束%>

以下列方式输出

 <div class="control-group hidden item_user_id"><div class="controls"><input class="hidden" id="item_user_id" name="item[user_id]" type="隐藏"/></div></div><div class="control-group select optional item_category"><label class="select optional control-label" for="item_category_id">Category</label><div class="controls"><;select class="select optional" id="item_category_id" name="item[category_id]"><option value=""></option><option selected="selected" value="1">选项1</option><option value="3">选项2</option><option value="4">选项3</option><div class="control-group string optional item_name"><label class="string optional control-label" for="item_name">Name</label><div class="controls"><;input class="string optional" id="item_name" name="item[name]" type="text" value="内衣"/></div></div><div class="control-group string optional item_description"><label class="string optional control-label" for="item_description">Description</label><div class="controls"><;input class="string optional" id="item_description" name="item[description]" type="text" value="test"/></div></div><div class="control-group boolean optional item_warm"><label class="boolean optional control-label" for="item_warm">Warm</label><div class="controls"><;input name="item[warm]" type="hidden" value="0"/><label class="checkbox"><input checked="checked" class="boolean optional" id="item_warm" name="item[warm]" type="checkbox" value="1"/></label></div></div><div class="control-group boolean optional item_cool"><label class="boolean optional control-label" for="item_cool">Cool</label><div class="controls"><;input name="item[cool]" type="hidden" value="0"/><label class="checkbox"><input checked="checked" class="boolean optional" id="item_cool" name="item[cool]" type="checkbox" value="1"/></label></div></div>

特别是复选框看起来很糟糕，如下所示

有没有人遇到过类似的问题，或者我只是做了一些愚蠢的事情?

感激地接受任何想法

解决方案

看起来 simple_form 的默认版本不能与 Bootstrap 3 完全兼容.因此，我不得不更改我的 gem 文件以阅读以下内容:

gem 'simple_form', '~>3.1.0.rc1'，github:'plataformatec/simple_form'，分支:'master'

一旦我重新运行初始化程序并重新启动应用程序，问题就解决了.

In the past I have used rails 3.x bootstrap 2.x and simple_form to great success. However, I have tried to created a new (not upgraded) Rails 4 / Bootstrap 3 app and although the simple_form syntax is able to be used and can even use nested forms, it looks as though the styling is not working. I have used rails-bootstrap-forms on a none model based form and that styling looks fine, however, I would prefer to use simple_form for the majority of my forms.

My files look like the following

gem

source 'https://rubygems.org'

gem 'rails', '4.1.6'
gem 'mysql2'
gem 'jquery-rails'
gem 'devise'

gem 'sass-rails'
gem 'coffee-rails', '~> 4.1.0'
gem 'bootstrap-sass', '~> 3.2.0'
gem 'autoprefixer-rails'
gem 'therubyracer', '0.11.4', :platforms => :ruby
gem 'uglifier', '>= 1.3.0'
gem 'jquery-ui-rails'
gem 'less-rails'
gem 'font-awesome-rails'
gem 'bootstrap_form'

gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc

gem 'jquery-turbolinks'
gem 'turbolinks', '1.3.0'

#Forms and user entry
gem 'simple_form'
gem 'cocoon'
gem 'country_select'
gem "ckeditor"
gem "gon"

application.css.scss

/*
 *= require_self
 *= require rails_bootstrap_forms
 *= require font-awesome
 *= require_tree .
 */

@import "bootstrap-sprockets";
@import "bootstrap";

I have the two initializers that have not been altered simple_form.rb and simple_form_bootstrap.rb

and a form looking like the following

<%= simple_form_for @item, :html => { :class => 'form-horizontal' } do |f| %>

  <% if f.error_notification %>
    <div class="alert alert-error fade in">
      <a class="close" data-dismiss="alert" href="#">&times;</a>
      <%= f.error_notification %>
    </div>
  <% end %>

  <%= f.input :user_id, :as => :hidden, :input_html => { :value => @userid }  %>
  <%= f.association :category %>
  <%= f.input :name %>
  <%= f.input :description %>

  <%= f.input :cool %>
  <%= f.input :cold %>


  <%= f.button :submit, :class => 'btn-primary' %>
  <%= link_to t('.cancel', :default => t("helpers.links.cancel")),
                items_path, :class => 'btn btn-default' %>
<% end %>

which outputs in the following way

      <div class="control-group hidden item_user_id"><div class="controls"><input class="hidden" id="item_user_id" name="item[user_id]" type="hidden" /></div></div>
      <div class="control-group select optional item_category"><label class="select optional control-label" for="item_category_id">Category</label><div class="controls"><select class="select optional" id="item_category_id" name="item[category_id]"><option value=""></option>
<option selected="selected" value="1">Option 1</option>
<option value="3">Option 2</option>
<option value="4">Option 3</option>
      <div class="control-group string optional item_name"><label class="string optional control-label" for="item_name">Name</label><div class="controls"><input class="string optional" id="item_name" name="item[name]" type="text" value="Underwear" /></div></div>
      <div class="control-group string optional item_description"><label class="string optional control-label" for="item_description">Description</label><div class="controls"><input class="string optional" id="item_description" name="item[description]" type="text" value="test" /></div></div>
      <div class="control-group boolean optional item_warm"><label class="boolean optional control-label" for="item_warm">Warm</label><div class="controls"><input name="item[warm]" type="hidden" value="0" /><label class="checkbox"><input checked="checked" class="boolean optional" id="item_warm" name="item[warm]" type="checkbox" value="1" /></label></div></div>
      <div class="control-group boolean optional item_cool"><label class="boolean optional control-label" for="item_cool">Cool</label><div class="controls"><input name="item[cool]" type="hidden" value="0" /><label class="checkbox"><input checked="checked" class="boolean optional" id="item_cool" name="item[cool]" type="checkbox" value="1" /></label></div></div>

In particular the checkboxes look really bad as shown below

Has anyone had any similar issues, or am I just doing something a bit dumb?

any thoughts gratefully accepted

解决方案

Looks like the default version of simple_form is not completely working with Bootstrap 3. I therefore had to change my gem file to read the following:

gem 'simple_form', '~> 3.1.0.rc1', github: 'plataformatec/simple_form', branch: 'master' 

This has resolved the issue once I reran the initializer and restarted the app.
