ruby-on-rails - 区分过去的事件和 future 的事件

Question

问题:如何显示具有 start_time<time.now 的事件& start_time>time.now在两个不同的表中？

我有scaffold event start_time:datetime title

事件 Controller :

def index
  @event = Event.all
end

index.html.haml:

 %table
    %thead
      %tr
        %th Start_time
        %th Title

    %tbody
      - @events.each do |event|
        %tr
          %td= event.start_time
          %td= event.title

谢谢:)

Answer 1

您可以简单地为过去和 future 的事件定义范围:

class Event < ActiveRecord::Base
  scope :in_the_past, { where('start_time < ?', Time.now }
  scope :in_the_future, { where('start_time > ?', Time.now }
end

那么你的观点将是:

_events_table.html.haml

%table
  %thead
    %tr
      %th Start_time
      %th Title

   %tbody
    - events.find_each do |event|
      %tr
        %td= event.start_time
        %td= event.title

index.html.haml

/ Past events
= render 'events_table', events: Event.in_the_past
/ Future events
= render 'events_table', events: Event.in_the_future
