如何修改Rails datetime_select助手的输入类型? [英] How can I modify the input type of the Rails datetime_select helper?

问题描述

我正在其中一种形式中使用Rails帮助器datetime_select.我目前需要将day，year，hour和minute的下拉列表更改为带有验证的文本框.有没有一种方法可以指定我要这些字段的文本框?还是可能会有其他帮手来满足我的需求?

I am using the Rails helper datetime_select in one of my forms. I currently have a requirement to change the dropdowns for day, year, hour, and minute to be textboxes with validation. Is there a way I can specify that I want textboxes for these fields? Or possibly a different helper that will do what I need?

这是我的用法

datetime_select(:campaign, :start_date, :order => [:day, :month, :year, :hour, :minute])

推荐答案

如何滚动自己的简单帮助程序，例如

how about rolling your own simple helper, like

def datetime_text_fields(object_name, method)
  html = text_field_tag("#{object_name}[#{method}(3i)]", Date.today.day.to_s, :length => 2)
  html << select_month(Date.today, :field_name => "#{object_name}[#{method}(2i)]")
  html << text_field_tag("#{object_name}[#{method}(1i)]", Date.today.year.to_s, :length => 4)
  html << " "
  html << text_field_tag("#{object_name}[#{method}(4i)]", Time.now.hour.to_s, :length => 2)
  html << ":"
  html << text_field_tag("#{object_name}[#{method}(5i)]", Time.now.min.to_s, :length => 2)
end

可以随意添加更多格式的东西/分隔符等，但是它基本上会返回正确的字段名称，以便将Rails标识为DateTime. Rails期望使用名为date(1i)，1i =年，2i =月等的字段.

Feel free to add more formatting stuff/separators etc. but it basically returns to correct field names for rails to be identified as DateTime. Rails expects fields named like date(1i), 1i = year, 2i = month etc.

老实说，我没有对其进行任何测试，但是控制台中的输出看起来很令人信服;)

Honestly I didn't test it or anything, but the output in console looked pretty convincing ;)
