新手问题 使用 will_paginate 分页问题
class BlogYear < ActiveRecord::Base default_scope :order => "name Desc" attr_accessible :name ,:blogs has_many :blogs end
使用 will_paginate 给 BlogYear 中 blogs 分页，
class Blog < ActiveRecord::Base belongs_to :blog_year attr_accessible :content , :title... end
并不能直接给 Blog 分页因为要根据 BlogYear 分组
Blog.paginate(:page => params[:page]).group_by(&:blog_year_id)

赞同 #2 楼 @blacktulip
@blogs = Blog.paginate(:page => params[:page])
<% @blogs.group_by(&:blog_year_id).each do |blog_year_id, blogs| %>
...
<% end %>
<%= will_paginate @blogs %>
