Question

我的rails应用程序中有一个博客功能。目前我在该网站上只有4位博客，并且有一种（非常不满意）的方式来这样做：

map.scarlet '/scarlet.:format', :controller => 'blogs', :action => 'show', :id => 'scarlet'
map.alba '/andreasweinas.:format', :controller => 'blogs', :action => 'show', :id => 'alba'

通过输入以下内容可以很方便地访问它们：mysuperwebsite.com/scarlet

现在我想为可访问的博客提供档案：

mysuperwebsite.com/scarlet/2009 - 显示2009年的所有条目

mysuperwebsite.com/scarlet/2009/06 - 显示2009年6月的所有条目

有人会建议如何a）改进我的博客路由，考虑到将来我会有更多的博主，以及b）如何在不破坏路径的情况下路由档案？我在想档案管理员？

型号：

# Blog.rb
class Blog < ActiveRecord::Base
  has_many :entries, :dependent => :destroy
  belongs_to :user
end

class Entry < ActiveRecord::Base
   named_scope :published, :conditions => ["published_at < ?", Time.zone.now], :order => 'published_at DESC' 
   belongs_to :blog
end

博客控制器：

 def show
    @blog = Blog.find_by_slug(params[:id])
    @entries = @blog.entries.published, :order => 'published_at DESC'

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @blog.entries }
      format.rss
    end
  end

这是未经测试的，但应该非常接近。不是DRYest解决方案，但您可以重构它。这将使日期过滤器工作并允许您拥有新博客并支持现有路线。享受

routes.rb

#(you don't need the .format) bit
# (if you have other routes, like /help, you need to have them before these, since these match /*, /\*/\*, and /\*/\*/\*

map.blogs '/:id/:year/:month', :controller => 'blogs', :action => 'show'
map.blogs '/:id/:year', :controller => 'blogs', :action => 'show'
map.blogs '/:id.:format', :controller => 'blogs', :action => 'show'

博客控制器：

def show
    @blog = Blog.find_by_slug(params[:id])

   if (params[:year])
       if (!params[:month])
           date_begin = Date.new(params[:year],1,1)
           date_end = Date.new(params[:year],12,31)
           date_end = Time.zone.now if date_end < Time.zone.now  # to prevent grabbing future posts
           @entries = Entries.find(:conditions => [blog => @blog, :published_at => date_begin..date_end ],
              :order => 'published_at DESC'
       else
           date_begin = Date.new(params[:year],params[:month],1)
           date_end   = date_being.end_of_month
           date_end = Time.zone.now if date_end < Time.zone.now  # to prevent grabbing future posts
           @entries = Entries.find(:conditions => [blog => @blog, :published_at => date_begin..date_end ],
              :order => 'published_at DESC'
       end
    else
        @blog.entries.published, :order => 'published_at DESC'
    end

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @entries }         # I changed this too
      format.rss
    end
  end
