ruby on rails datetime select not updating db

Question

im trying to use the builtin ruby helper for datetime select, though it doesnt seem to be passing the values through to 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])

console output

Answer 1

According to your label it's :date_and_time field in your database, right? If so you should use it in your datetime_select :

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

发现问题出在控制器内，仍然指的是我们已有的旧命名，因为进行所有更改似乎都可行
