Simple_form: Remove outer label for an inline checkbox with label
提问by David Nix
Using Simple_form 2.0.2

The simple form code using HAML:
使用 HAML 的简单表单代码：
= f.input :remember_me, as: :boolean, inline_label: 'Remember me'
But it renders this:
但它呈现这个：
<div class="control-group boolean optional">
<label class="boolean optional control-label" for="admin_remember_me">Remember me</label>
<div class="controls">
<input name="admin[remember_me]" type="hidden" value="0" />
<label class="checkbox"><input class="boolean optional" id="admin_remember_me" name="admin[remember_me]" type="checkbox" value="1" />Remember me</label>
</div>
</div>
How do I remove that first label that's rendered, so that I only have the inline label?
如何删除呈现的第一个标签，以便我只有内联标签？

Found a solution after much Google fu.
经过大量的Google fu后找到了解决方案。
Use input_fieldinstead of inputwhich won't automatically generate a label.
使用input_field代替inputwhich 不会自动生成标签。
= f.input_field :remember_me, as: :boolean, inline_label: 'Remember me'

For whom it doesn't work
对谁不起作用
= f.input_field ...
= f.input_field ...
Use this way
用这种方式
= f.check_box ...
= f.check_box ...

With simple_form 2.1.0 and rails 3.0.20, none of the solutions listed here worked (I don't want to use f.input_field because it's an admission of defeat).
使用 simple_form 2.1.0 和 rails 3.0.20，这里列出的解决方案都不起作用（我不想使用 f.input_field 因为它承认失败）。
The missing part is the boolean_styleoption:
缺少的部分是boolean_style选项：
options.merge!({label: false, boolean_style: :inline})
I suggest you create a custom input for this (e.g.: inline_checkbox)
我建议您为此创建一个自定义输入（例如：inline_checkbox）
boolean_style is configured as :nested by default, I think:
boolean_style 配置为 :nested 默认情况下，我认为：
# Defaults to :nested for bootstrap config.
# :inline => input + label
# :nested => label > input
config.boolean_style = :nested

Maybe too late, but inspired by gamov answer I have made this a custom wrapper from inline bootstrap checkbox in the initializer file 'config/simple_form_bootstrap.rb':
也许为时已晚，但受 gamov 答案的启发，我已将其从初始化文件“ config/simple_form_bootstrap.rb”中的内联引导程序复选框中的自定义包装器：
config.wrappers :horizontal_radio_and_checkboxes, tag: 'div', class: 'form-group', error_class: 'has-error' do |b|
b.use :html5
b.optional :readonly
b.use :label, class: 'col-sm-3 control-label'
b.use :input
b.use :error, wrap_with: { tag: 'span', class: 'help-block' }
b.use :hint, wrap_with: { tag: 'p', class: 'help-block' }
end
which generates this html:
生成这个html：
<div class="form-group boolean optional user_admin">
<label class="boolean optional col-sm-3 control-label" for="user_admin">Admin</label>
<div class="col-sm-9 checkbox-inline">
<input name="user[admin]" value="0" type="hidden">
<input class="boolean optional" id="user_admin" name="user[admin]" value="1" type="checkbox">
</div>

.control-group.error .help-inline {
display: none;
}
This should work, it works for me on rails 3.2 and simple_form 2.x+
这应该有效，它适用于 rails 3.2 和 simple_form 2.x+
