Ruby on rails 包含\u blank不适用于选择\u年份的rails表单输入rails 6

出于某种奇怪的原因，年份仍然显示为rails提供的select_year输入的默认值。我无法获取include_blank：选择年份填充表单输入。如何强制“选择年/选择月”输入显示“包含”空白文本，而不是“当前年/当前日”值？仅供参考：提示对输入也不起作用

_calendar_form.html.erb

这是因为，就像今天一样 您可以将其设置为零以使其工作。您也可以跳过include_空白，因为您还有提示

我没有意识到我可以将它设置为nil，因为文档只显示值作为第一个参数。非常感谢。

<%= form_tag calendar_path(@calendar), method: :get do %>
<%= select_year(Date.today, {:prompt => "Select Year", :start_year => DateTime.now.year, :end_year => DateTime.now.year - 8, prefix: 'select'}, {:field_name => 'year', :id => 'start-year', class: 'ui dropdown', include_blank: 'Select Year'}) %>
<% end %>

<%= select_year nil, {prompt: "Select Year", start_year: DateTime.now.year, end_year: 8.years.ago.year, prefix: 'select'}, {field_name: 'year', id: 'start-year', class: 'ui dropdown', include_blank: 'Select Year'} %>

def new 
  @date = nil
end

def create
  @date = some_params[:year] # depending on use-case obviously
  # if you need to re-render the form the value is retained
end    

= select_year @date ......
