date_select和time_select沒有在rails中使用start_year和end_year和order參數？

Question

我使用導軌date_select和time_select以及以下選項。 但date_selectstart_year和end_year和order選項不起作用。併爲time_selectampm:true選項不起作用。

<%= label_tag :date,"Date" %> 
    <%= date_select :date, { start_year: Date.today.year - 1, :end_year => Date.today.year, order: [:day, :month, :year] } %> 

    <%= label_tag :check_in,"Check In Time" %> 
    <%= time_select :check_in, {ampm: true} , {} %> 

    <%= label_tag :check_out,"Check Out Time" %> 
    <%= time_select :check_out, {ampm: true}, {} %> 

以及如何應用類屬性。我給這樣的，但造型不起作用。

<%= time_select :check_out, {ampm: true} ,{:class => 'form-control' } %> 

Answer 1

on Rails的API docs的date_select被定義爲

date_select（對象，方法，選項= {}，html_options = {}）

您應將options作爲第二個參數，當它應該是第三個參數時。

溶液1：

<%= date_select :date, nil, { start_year: Date.today.year - 1, :end_year => Date.today.year, order: [:day, :month, :year] } %> 

有多個用於time_select同樣的問題：

time_select（對象，方法，選項= {}，html_options = {}）

解決方案2：

<%= time_select :check_out, nil, {ampm: true} ,{:class => 'form-control' } %> 

Answer 2

參數順序錯誤。它應該是：

<%= label_tag :date,"Date" %> 
<%= date_select :date, {}, { start_year: Date.today.year - 1, :end_year => Date.today.year, order: [:day, :month, :year] } %> 

<%= label_tag :check_in,"Check In Time" %> 
<%= time_select :check_in, {}, {ampm: true} %> 

<%= label_tag :check_out,"Check Out Time" %> 
<%= time_select :check_out, {}, {ampm: true} %>
