按月/年红宝石显示帖子 [英] display posts by month/year ruby

问题描述

不确定从何处开始，所以这里开始。.我正在建立一个小博客，在其中显示每个帖子的日期，加班每个月会有很多博客帖子，我希望将这些帖子分组在一起

Not sure where to start with this so here goes.. I am building a small blog in which the date of each post is displayed, overtime there will be many blog posts per month, for which i would like to group together by the month it was published.

我想在视图中这样显示它

I want to display it like this in the view

Archives

January 2013
February 2013
March 2013
etc

当我单击给定月份时，想法是将带我到该月内发布的所有帖子。

When i click on a given month the idea is it will take me to all the posts that where published within that month.

到目前为止，我可以按月份和年份对所有帖子进行分组

So far I can group all the posts by month and year

@posts_by_month = Post.all.group_by { |post| post.created_at.strftime("%B %Y") }

然后在我看来

<% @posts_by_month.each do |m| %>
  <%= m %>
<% end %>

在视图中返回哪个

["July 2013", [#<Post id: 1, title: "Ruby News", comments: "dsfdsfdsfdsfdsfds", category_id: 1, user_id: 1, created_at: "2013-07-26 07:10:25", updated_at: "2013-07-26 07:19:27", photo_file_name: "pf-7.jpg", photo_content_type: "image/jpeg", photo_file_size: 162495, photo_updated_at: "2013-07-26 07:19:26">]] 

目前哈希，其中月/年是关键，然后我在数组中的所有帖子都正确吗？

So at the moment i have a hash where the month/year is the key and then all my posts in an array, is that correct?

我要显示的是月/年，然后点击该月即可进入该月的所有帖子

All i want to display is the Month/Year and then click that month to be taken to all the posts for that month

感谢任何帮助

编辑

好吧，我，忘记了键/值配对的基础知识，我只有要显示的日期

ok silly me, forgot my basics on key/value pairing, i have got just the date to display

<% @posts_by_month.each do |m,p| %>
  <%= link_to m %>
<% end %>

现在，我只需要单击链接即可查看该月的所有帖子

Now i just need to be able to click the link to see all posts for that month

推荐答案

您可以

= link_to m, posts_path(:month => m)

现在在个帖子中#index ，根据 params [：month]

if params[:month]
  date = Date.parse("1 #{params[:month]}")  # to get the first day of the month
  @posts = Post.where(:created_at => date..date.end_of_month)  # get posts for the month
else
  @posts = Post.all
end
