在我的应用程序中,我创建了一个最近的帖子功能.
@recentposts = Post.all(:order => 'created_at DESC',:limit => 5)
这个变量有些麻烦.当我运行测试我有以下错误：
DEPRECATION WARNING: Relation#all is deprecated. If you want to eager-load a relation,you can call #load (e.g.
Post.where(published: true).load). If you want to get an array of records from a relation,you can call #to_a (e.g.Post.where(published: true).to_a). (called from show at /home/mateusz/rails4/Bloggers/app/controllers/users_controller.rb:18)
我是Google上的seraching解决方案,但我没有找到它
解决方法
只写：
@recentposts = Post.order('created_at DESC').limit(5)
to_a没有明确的必要,因为数据在需要时被延迟加载.
