simple_form 中的自定义包装器:重复输入

Custom wrapper in simple_form: duplicated input

我在我的输入周围使用 simple_form gem in my Rails 5.2 application. Currently, I'm having a bit of a problem when using custom wrappers

我的包装纸

config.wrappers :mini_input, tag: 'div', class: 'row responsive-label', error_class: 'error' do |b|
  b.use :html5
  b.wrapper tag: 'div', class: 'col-sm-12 col-md-3' do |c|
    c.use :label_input
  end
  b.wrapper tag: 'div', class: 'col-sm-12 col-md-4' do |c|
    c.use :input
  end
end

我的表格

simple_form_for(@user) do |f|
  ...
  <%= f.input :name, required: true, label: "Name", autofocus: true, wrapper: :mini_input %>
  ...
end

预期输出

<div class="row responsive-label">
  <div class="col-sm-12 col-md-3">
    <label ...>
  </div>
  <div class="col-sm-12 col-md-4">
    <input ...>
  </div>
</div>

...实际输出

<div class="row responsive-label">
  <div class="col-sm-12 col-md-3">
    <label ...>
    <input ...>    <!-- This input should not be here -->
  </div>
  <div class="col-sm-12 col-md-4">
    <input ...>
  </div>
</div>

我在想我的包装器配置中可能有错误,我现在找不到它。

正如我的一个朋友 in a tweet 指出的那样,解决方案是在包装器配置中使用 label 而不是 label_input

config.wrappers :mini_input, tag: 'div', class: 'row responsive-label', error_class: 'error' do |b|
  b.use :html5
  b.wrapper tag: 'div', class: 'col-sm-12 col-md-3' do |c|
    # c.use :label_input  Wrong
    c.use :label
  end
  b.wrapper tag: 'div', class: 'col-sm-12 col-md-4' do |c|
    c.use :input
  end
end
