简单的表单、包装单选按钮和复选框

作为继续生活的快速技巧,将其添加到application helper的底部可以将每个标签/输入对简单地包装在div中:

module SimpleForm::ActionViewExtensions::Builder

  def collection_radio(attribute, collection, value_method, text_method, options={}, html_options={})
    collection.map do |item|
      value = item.send value_method
      text  = item.send text_method

      default_html_options = default_html_options_for_collection(item, value, options, html_options)

      @template.content_tag(:div, radio_button(attribute, value, default_html_options) <<
        label("#{attribute}_#{value}", text, :class => "collection_radio"))
    end.join.html_safe
  end

  def collection_check_boxes(attribute, collection, value_method, text_method, options={}, html_options={})
    collection.map do |item|
      value = item.send value_method
      text  = item.send text_method

      default_html_options = default_html_options_for_collection(item, value, options, html_options)
      default_html_options[:multiple] = true

      @template.content_tag(:div, 
      check_box(attribute, default_html_options, value, '') <<
        label("#{attribute}_#{value}", text, :class => "collection_check_boxes"))
    end.join.html_safe
  end

end

创建新目录“app/inputs”,

创建“collection_radio_buttons_input.rb”文件,然后粘贴

class CollectionRadioButtonsInput < SimpleForm::Inputs::CollectionRadioButtonsInput
  def item_wrapper_class
    "radiobox"
  end
  def build_nested_boolean_style_item_tag(collection_builder)
    collection_builder.radio_button + template.content_tag(:span,collection_builder.text)
  end
end

在config/initializers/simple_form.rb中打开选项“config.inputs_discovery”

喂!

现在,将使用此控件而不是默认的单选按钮简单表单控件,您可以自由使用任何格式。

我刚用CSS做的。我用class=“radio button”在按钮和标签周围打了一个div。然后我将此添加到我的样式表(SASS)中:

.radio-buttons {
  margin: .5em 0;
  span input {
    float: left;
    margin-right: .25em;
    margin-top: -.25em;
  }
  #this grabs the MAIN label only for my radio buttons 
  #since the data type for the table column is string--yours may be different
  label.string { 
    margin-bottom: .5em !important;
  }

  clear: both;
}

.form-block {
  clear: both;
  margin-top: .5em;
}

 .radio-buttons span {
  clear: both;
  display:block;
 }
