如何在simple_form中使用div来包围输入而不包围其各自的标签（使用f.input）

Question

I'm using a custom theme for twitter bootstrap that surrounds the inputs in a div this way:

    = simple_form_for(@user_session) do |f|
      .control-group
        = f.label :username, 'Usuario', class: 'control-label'
        .controls
          = f.input_field :username

I want to use only f.input to save coding in large forms, I ran rails generate simple_form:install to be able to modify the configuration, currently I have:

    = simple_form_for(@user_session) do |f|
      = f.input :username, :label => 'Usuario'

And it generates almost all the markup I need (adding the respective classes in initializers/simple_form):

<form action="/user_sessions" class="form-horizontal new_user_session" method="post">
      ...
      <div class="control-group username">
          <label class="username control-label" for="user_session_username">Usuario</label>
          <input class="username" id="user_session_username" name="user_session[username]" size="50" type="text" />
      </div>
      ...
</form>

It only needs and extra 'div' with the class 'controls' surrounding the input tag but not the label, is there any way to achieve this?

Thanks!

Finally found how to do it, configuring the wrapper this way adds the required div for bootstrap:

initializers/simple_form

config.wrappers :bootstrap, :tag => 'div', :class => 'control-group', :error_class => 'error' do |b|
  b.use :html5
  b.use :placeholder
  b.use :label
  b.wrapper :tag => 'div', :class => 'controls' do |ba|
    ba.use :input
    ba.use :error, :wrap_with => { :tag => 'span', :class => 'help-inline' }
    ba.use :hint,  :wrap_with => { :tag => 'p', :class => 'help-block' }
  end
end

config.default_wrapper = :bootstrap
