如何在Rails中的date_select帮助器中设置默认日期 [英] How to set default date in date_select helper in Rails

问题描述

我正在尝试在我的Rails应用程序（2.3.5）中设置生日帮助日期。目前它是这样的。

 <％= f.date_select：date_of_birth，：start_year => Time.now.year  -  110，：end_year => Time.now.year％> 
  

这将生成一个功能完整的日期字段集，工作正常但.... >

他们默认为今天不适合出生日期的日期（我不知道是什么，但除非你在运行新生儿单位今天的日期似乎不太理想）。我想要2010年1月1日（或2011年或任何一年恰好是）阅读。使用：默认选项已被证明不成功。我尝试了许多可能性，包括：

 <％= f.date_select：date_of_birth，：default => {：year => Time.now.year，：month => 'Jan'，：day => 1}，：start_year => Time.now.year  -  110，：end_year => Time.now.year％> 
  

和

 <％= f.date_select：date_of_birth，：default => Time.local（2010，'Jan'，1），：start_year => Time.now.year  -  110，：end_year => Time.now.year％> 
  

这些都不会改变第一个例子的行为。默认选项是否按照描述进行工作？看来这应该是一个相当直接的事情。

解决方案

我认为最简单的方法是将它分配给控制器，例如新操作：

  @person = Person.new（：date_of_birth =>2010-01-01.to_date）
  

然后在您的意见将获得正确的日期。

编辑：

如果要在模型级别分配默认值，可以尝试使用<一个href =http://blog.phusion.nl/2008/10/03/47/ =noreferrer>插件。但是我没有尝试过。

I'm trying to set up a date of birth helper in my Rails app (2.3.5). At present it is like so.

<%= f.date_select :date_of_birth, :start_year => Time.now.year - 110, :end_year => Time.now.year %>

This generates a perfectly functional set of date fields that work just fine but....

They default to today's date which is not ideal for a date of birth field (I'm not sure what is but unless you're running a neonatal unit today's date seems less than ideal). I want it to read Jan 1 2010 instead (or 2011 or whatever year it happens to be). Using the :default option has proven unsuccessful. I've tried many possibilities including;

<%= f.date_select :date_of_birth, :default => {:year => Time.now.year, :month => 'Jan', :day => 1}, :start_year => Time.now.year - 110, :end_year => Time.now.year %>

and

<%= f.date_select :date_of_birth, :default => Time.local(2010,'Jan',1), :start_year => Time.now.year - 110, :end_year => Time.now.year %>

None of this changes the behaviour of the first example. Does the default option actually work as described? It seems that this should be a fairly straightforward thing to do.

解决方案

I think that easiest way is to assign it in controller, for example for new action:

@person = Person.new(:date_of_birth => "2010-01-01".to_date)

Then in your view you will get correct date.

EDIT:
If you want to assign default value on model level, you can try do it with plugin. However I haven't try it.
