如何使用 simple_form 和 bootstrap 生成无线电内联标签? [英] How to generate a radio-inline label with simple_form and bootstrap?

问题描述

我正在使用:

<%= simple_form_for @visitor, html: {class: 'form-inline'} do |f|％＞<%= f.error_notification %><%= f.input :favorite, label: false, as:radio_buttons %><%= f.submit "选择!", :class =>"btn btn-primary"%><%结束%>

我得到了这个 html:

<div class="控件"><label class="radio"><input class="radio_buttons required" id="visitor_favourite_true" name="visitor[favourite]" type="radio" value="true"/>是的<label class="radio"><input class="radio_buttons required" id="visitor_favourite_false" name="visitor[favourite]" type="radio" value="false"/>不

但我正在寻找的是一种将标签生成为单选内联的方法，因为这是我想要的样式:

有一个类似的问题 here 但是对于radio inline"类，并且不能像生成radio-inline那样工作.

我使用的是 simple_form 3.0.2 并尝试了 3.1.0rc2 和 Bootstrap 3.2.0 with rails 4.1.4无论如何或解决这个问题的方法?

解决方案

通过从这里获取灵感 answer 我设法通过创建一个 :radio_buttons_inline 输入类型来做到这一点.

创建文件:

app/inputs/radio_buttons_inline_input.rb

有这个内容:

class RadioButtonsInlineInput 

然后像这样在你的视图中使用它:

<%= simple_form_for @visitor do |f|％＞<%= f.error_notification %><%= f.input :favorite, :as =>:radio_buttons_inline%><%结束%>

这将 html 呈现为:

<div class="control-group radio_buttons_inline requiredvisitor_favourite"><div class="控件"><label class="radio-inline"><input class="radio_buttons_inline required" id="visitor_favourite_true" name="visitor[favourite]" type="radio" value="true"/>是的<label class="radio-inline"><input class="radio_buttons_inline required" id="visitor_favourite_false" name="visitor[favourite]" type="radio" value="false"/>不

I'm using:

<%= simple_form_for @visitor, html: {class: 'form-inline'} do |f| %>
    <%= f.error_notification %>
    <%= f.input :favorite, label: false, as: :radio_buttons %>
    <%= f.submit "Choose!", :class => "btn btn-primary"%>
<% end %>

And I get this html:

<div class="control-group radio_buttons required visitor_favourite">
    <div class="controls">
        <label class="radio">
            <input class="radio_buttons required" id="visitor_favourite_true" name="visitor[favourite]" type="radio" value="true" />
            Yes
        </label>
        <label class="radio">
            <input class="radio_buttons required" id="visitor_favourite_false" name="visitor[favourite]" type="radio" value="false" />
            No
        </label>
    </div>
</div>

But what I'm looking for is a way to generate the labels as radio-inline because that is the style i want:

<label class="radio-inline"> 

There is a similar question here but for the "radio inline" class and desn't work as to generate radio-inline.

I'm using simple_form 3.0.2 and tried 3.1.0rc2 and Bootstrap 3.2.0 with rails 4.1.4 Anyway or method to solve this?

解决方案

By getting inspiration form this answer I managed to do it by creating a :radio_buttons_inline input type.

Create the file:

app/inputs/radio_buttons_inline_input.rb

with this content:

class RadioButtonsInlineInput < SimpleForm::Inputs::CollectionRadioButtonsInput
  def input
    label_method, value_method = detect_collection_methods
    @builder.send("collection_radio_buttons", attribute_name, collection, value_method,
      label_method, input_options, input_html_options, 
      &collection_block_for_nested_boolean_style)
  end

  protected
    def item_wrapper_class
      "radio-inline"
    end
end

And then use it in your view like so:

<%= simple_form_for @visitor do |f| %>
    <%= f.error_notification %>
     <%= f.input :favourite, :as => :radio_buttons_inline%>
<% end %>

This renders the html as:

<div class="control-group radio_buttons_inline required visitor_favourite">
    <div class="controls">
        <label class="radio-inline">
            <input class="radio_buttons_inline required" id="visitor_favourite_true" name="visitor[favourite]" type="radio" value="true" />
               Yes
        </label>
        <label class="radio-inline">
            <input class="radio_buttons_inline required" id="visitor_favourite_false" name="visitor[favourite]" type="radio" value="false" />
            No
        </label>
    </div>
 </div>
