使用 kaminari 进行月份分页

发布于 2024-11-30 07:31:51 字数 776 浏览 3 评论 0原文

我想按月对帖子进行分页，所以我在帖子模型中添加了以下范围

class Post
  include Mongoid::Document
  include Mongoid::Timestamps

  scope :by_month, lambda {|end_date| Post.order_by(:created_at => :asc).where(:created_at.gte => (end_date.to_date.beginning_of_month), :created_at.lte => (end_date.to_date))}
end

在我的控制器中，我将其放入

def show
  @posts = Post.by_month(Time.now).page(params[:page]).per(20)
end

视图中

<%= paginate @posts, :theme => 'month_theme' %>
<%= render @posts %>

问题：

分页无法按月工作，我想在页面中显示一个月的所有结果，替换 params[:page]通过 params[:month]=2 或 params[:month]=Feb
我如何查看“2011 年 8 月”而不是 1,2
循环月份和年份，就像您在“Jan”中转到上一个时一样2011 年”将转到“2010 年 12 月”

原文

I want to paginate posts by month so I added following scope in Post model

class Post
  include Mongoid::Document
  include Mongoid::Timestamps

  scope :by_month, lambda {|end_date| Post.order_by(:created_at => :asc).where(:created_at.gte => (end_date.to_date.beginning_of_month), :created_at.lte => (end_date.to_date))}
end

In my controller I put

def show
  @posts = Post.by_month(Time.now).page(params[:page]).per(20)
end

In view

<%= paginate @posts, :theme => 'month_theme' %>
<%= render @posts %>

Problems:

pagination is not working by month, I want to show all result of a month in a page, replacing params[:page] by params[:month]=2 or params[:month]=Feb
How do I view 'August 2011' instead of 1,2
Loop month and year like when you goto previous while in 'Jan 2011' it will goto 'Dec 2010'

我想这实际上并不是分页的问题。处理查询的 params[:month] 值与页面偏移切换不同。您可能不需要分页库。

像这样简单地创建这些链接怎么样？

控制器：

@posts = Post.by_month(Time.parse(params[:month]) || Time.now)

视图：

<% Post.only(:created_at).map {|p| p.created_at.to_date.beginning_of_month}.uniq.sort.each do |m| -%>
  <%= link_to_unless_current m, :month => m %> 
<% end -%>

当然，如果需要，您可以将此查询与普通分页结合起来。但在这种情况下，分页链接不应与月份链接混合在一起。

I suppose this is not really a matter of pagination. Dealing with the params[:month] value for the query is something different from the page offset switching. You might not need a pagination library for that.

How about simply creating those links like this?

controller:

@posts = Post.by_month(Time.parse(params[:month]) || Time.now)

view:

<% Post.only(:created_at).map {|p| p.created_at.to_date.beginning_of_month}.uniq.sort.each do |m| -%>
  <%= link_to_unless_current m, :month => m %> 
<% end -%>

Of course you can combine this query with normal pagination if needed. But the pagination links should not be mixed with the month links in that case.
