我有一个Rails应用程序,它使用AngularJS显示和异步更新对象列表(配置为AngularJS资源)。服务器端是否有一种简单的方法对该表进行分页?

will_paginate gem提供了一种在Rails控制器和模型中对查询进行分页的方法。来自github自述文件:

## perform a paginated query:
@posts = Post.paginate(:page => params[:page])

# or, use an explicit "per page" limit:
Post.paginate(:page => params[:page], :per_page => 30)

## render page links in the view:
<%= will_paginate @posts %>

您可以自定义默认页面内容:

# for the Post model
class Post
  self.per_page = 10
end

# set per_page globally
WillPaginate.per_page = 10

使用Active Record 3,您可以执行以下操作:

# paginate in Active Record now returns a Relation
Post.where(:published => true).paginate(:page => params[:page]).order('id DESC')

# the new, shorter page() method
Post.page(params[:page]).order('created_at DESC')
