Rails 3 date_select仅适用于年份 [英] Rails 3 date_select for year only

问题描述

我在Rails 3应用程序中有一个表单，我想在其中使用方法:grad_year仅为年份创建一个select标记.我可以正常使用date_select并添加:discard_month和:discard_day来进行所有工作-并进行存储.但是，当我渲染@profile.grad_year时，我得到了月和日的值.因此，我想知道如何仅 存储和呈现@profile.grad_year的年份?

这是表格:

<%= f.date_select :grad_year, {:start_year => Time.now.year, :end_year => Time.now.year - 95, :discard_day => true, :discard_month => true}, :selected => @profile.grad_year %>

在我的迁移中:

t.date :grad_year

解决方案

Rails有一个select_year助手:

http://apidock.com/rails/ActionView/Helpers/DateHelper/select_year

因此您的代码应如下所示:

f.select_year(Date.today, :start_year => Time.now.year, :end_year => Time.now.year - 95, :field_name => 'grad_year')

I have a form in my Rails 3 app where I want to create a select tag for just the year on a method :grad_year. I have everything working - and storing - properly using date_select and adding :discard_month and :discard_day. However when I render @profile.grad_year I get the month and day values. So I'm wondering how to store and render only the year for @profile.grad_year?

Here is the form:

<%= f.date_select :grad_year, {:start_year => Time.now.year, :end_year => Time.now.year - 95, :discard_day => true, :discard_month => true}, :selected => @profile.grad_year %>

In my migration:

t.date :grad_year

解决方案

Rails has a select_year helper:

http://apidock.com/rails/ActionView/Helpers/DateHelper/select_year

So your code should look like:

f.select_year(Date.today, :start_year => Time.now.year, :end_year => Time.now.year - 95, :field_name => 'grad_year')
