【问题描述】：

我尝试使用内置的 ruby 帮助器进行日期时间选择，尽管它似乎没有将值传递给 ActiveRecord

form.haml.html

.row
      .two.columns
        = f.label :date_and_time, :class =>'left inline'
      .ten.columns
        = f.datetime_select('datetime', :prompt => {:day => 'Choose day', :month => 'Choose month', :year => 'Choose year'}, :order => [:day, :month, :year])

控制台输出

标签： ruby-on-rails forms datetime rails-activerecord

【解决方案1】：

根据您的标签，它是您数据库中的:date_and_time 字段，对吗？如果是这样，您应该在 datetime_select 中使用它：

= f.datetime_select :date_and_time, :prompt => {:day => 'Choose day', :month => 'Choose month', :year => 'Choose year'}, :order => [:day, :month, :year])

【讨论】：

na 标签与数据库中的实际字段不同
从我在控制台上看到的表单正在传递哈希，但 activerecord 似乎没有看到它

【解决方案2】：

发现问题出在控制器内部，仍然指的是我们使用的旧命名，因为所做的更改似乎都在工作
