我在哪里放置带有参数和数学的自定义 rails 方法？
Where do I put in a custom rails method with paramaters and math?
我有一个在 ruby 中制作的自定义方法，我希望将其放入我的 rails 应用程序中。
您可以在这里进行测试：https://repl.it/Ezqr/20
def time_clock(hour, min)
...
end
我还有一个带有简单脚手架的 rails 应用程序。我 运行 的脚手架是
rails g scaffold Timeclock hour_in:integer minutes_in:integer
我希望能够将我的自定义 time_clock 方法放入我的 rails 应用程序并在视图中看到它。但是方法去哪儿了呢？或者至少我应该如何将它实现到我的 rails 应用程序中？它进入控制器还是模型？...帮助！
在我看来，我是通过使用这段代码让它工作的。有更好的做法吗？

您可以在您的视图中查看此代码 xxx.html.erb
<div id="page_wrapper">
<p id="notice"><%= notice %></p>
<h1>Listing Timeclocks</h1>
<% @timeclocks.each do |timeclock| %>
<div class="timeclock_wrapper">

你可以创建一个辅助方法，比如 helpers/application.rb
module ApplicationHelper
def min_hour_and_half_hour(timeclock)
minutes = timeclock.minutes_in % 60
fin_hour = (timeclock.hour_in + 8) - 12
if (57 <= minutes) && (minutes <= 59) || (0 <= minutes) && (minutes <= 2)
minutes = "00"
minutes_with_30 = "30"
fin_hour_with_30 = fin_hour
elsif (3 <= minutes) && (minutes <= 8 )
minutes = "06"
minutes_with_30 = "36"
fin_hour_with_30 = fin_hour
elsif (9 <= minutes) && (minutes <= 14)
minutes = "12"
minutes_with_30 = "42"
fin_hour_with_30 = fin_hour
elsif (15 <= minutes) && (minutes <= 20)
minutes = "18"
minutes_with_30 = "48"
fin_hour_with_30 = fin_hour
elsif (21 <= minutes) && (minutes <= 26 )
minutes = "24"
minutes_with_30 = "54"
fin_hour_with_30 = fin_hour
elsif (27 <= minutes) && (minutes <= 32 )
minutes = "30"
fin_hour_with_30 = fin_hour + 1
minutes_with_30 = "00"
fin_hour_with_30 = fin_hour + 1
elsif (33 <= minutes) && (minutes <= 38)
minutes = "36"
minutes_with_30 = "06"
fin_hour_with_30 = fin_hour + 1
elsif (39 <= minutes) && (minutes <= 44)
fin_hour_with_30 = fin_hour + 1
minutes = "42"
minutes_with_30 = "12"
elsif (45 <= minutes) && (minutes <= 50)
fin_hour_with_30 = fin_hour + 1
minutes = "48"
minutes_with_30 = "18"
elsif (51 <= minutes) && (minutes <= 56)
fin_hour_with_30 = fin_hour + 1
minutes = "54"
minutes_with_30 = "24"
else
minutes = min % 60
end
minutes, fin_hour_with_30, fin_hour
end
end
这会是一些清晰整洁的代码。
