Ruby on Rails group_by(如何按月对事件进行分组) [英] Ruby on Rails group_by (how to group events by month)

问题描述

大家好，我是 Rails 新手.我有一个创建事件的控制器，我想按月(此类事件日期的月份)对它们进行分组.我正在使用 rails 4，这是我的代码.

这是我的控制器

def 索引@events = Event.all@event_months = @events.group_by { |t|t.due_at.beginning_of_month }结尾

这是我的视图代码

<% @event_months.each do |month, events|％＞<h2><%=month.strftime('%B')%></h2><% 事件中的事件%>
<a href="<%= event.url %>">
<%= image_tag event.image_url(:normal), :class =>'eimage', :style =>'宽度:100%;'％＞
<div class='event-content'><h1 class='event-title'><%= event.name %></h1><h2 class='event-place'><%= event.where %></h2><h3 class='event-time-date'><%= event.start_time.strftime("%B %d @ %I:%M %p") %></h3>
</a>

<%结束%><%= link_to 'Show'，事件 %><%= link_to 'Edit', edit_event_path(event) %><%= link_to 'Destroy', event, method: :delete, data: { confirm: 'Are you sure?'}%><%结束%>

提前致谢.

解决方案

def index@events = Event.all@event_months = @events.group_by { |t|t.due_at.month }结尾

视图中的月份名称由

给出

日期::MONTHNAMES[月]

Hey Guys I am new to rails. I have a controller that create events and I want to group them by month (the month of such event date). I am using rails 4 here is my code.

This is my controller

def index
 @events = Event.all
 @event_months = @events.group_by { |t| t.due_at.beginning_of_month }
end

This is my view code

<% @event_months.each do |month, events| %>
  <h2><%= month.strftime('%B') %></h2>
    <% for event in evetns %>
     <div class='event-card'>
      <a href="<%= event.url %>">
       <div class='event-image'>
        <%= image_tag event.image_url(:normal), :class => 'eimage', :style =>  'width:100%;' %>
       </div>
       <div class='event-content'>
        <h1 class='event-title'><%= event.name %></h1>
        <h2 class='event-place'><%= event.where %></h2>
        <h3 class='event-time-date'><%= event.start_time.strftime("%B %d @ %I:%M %p") %></h3>
       </div>
      </a>
     </div>
   <% end %>
 <%= link_to 'Show', event %>
 <%= link_to 'Edit', edit_event_path(event) %>
 <%= link_to 'Destroy', event, method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>

Thank in advance.

解决方案

def index
 @events = Event.all
 @event_months = @events.group_by { |t| t.due_at.month }
end

Month Name in view is given by

Date::MONTHNAMES[month]
