无法将nil转换为数组will_paginate

Question

你好伙计我在rails 3中遇到了will_paginate的问题,我在我的constroller里有这个

@posts = Post.paginate(:all,
  :include => [:author, :categories],
  :conditions=>"status = 'published'", 
  :order=>"blog_posts.created_at DESC",
  :per_page => 1, :page => params[:page])

和@%= will_paginate @posts%>在我的视图中,但我得到此错误无法将nil不断转换为数组.

谁能帮我 ？

提前致谢

Answer 1

您需要安装will_paginate版本3.0.pre2才能在数据库级别而不是在阵列上进行分页工作.

gem 'will_paginate', '3.0.pre2'

Answer 2

试着这样做:

@posts = Post.includes(:author, :categories).where(:status => "published").order("blog_posts.created_at DESC").paginate(:per_page => 1, :page => params[:page])

这是Rails 3的首选方式.
