为什么我得到“未定义的方法‘分页’"?生产错误? [英] Why do I get "undefined method 'paginate'" error in production?
问题描述
在生产服务器上使用 will_paginate 时出现此错误:
I get this error when using will_paginate on production server:
I, [2013-10-24T20:17:40.386696 #18564] INFO -- : Started GET "/meals" for 190.273.432.55 at 2013-10-24 20:17:40 +0000
I, [2013-10-24T20:17:40.388972 #18564] INFO -- : Processing by MealsController#index as HTML
I, [2013-10-24T20:17:40.395022 #18564] INFO -- : Completed 500 Internal Server Error in 6ms
F, [2013-10-24T20:17:40.396720 #18564] FATAL -- :
NoMethodError (undefined method `paginate' for #<ActiveRecord::Relation::ActiveRecord_Relation_Meal:0x00000005080598>):
app/controllers/meals_controller.rb:5:in `index'
这是我在控制器中使用它的方式:
This is how I use it in the controller:
@meals = current_user.meals.order("created_at DESC").paginate(:page => params[:page], :per_page => 6)
我的观点是:
<%= will_paginate @meals %>
我已经尝试过 "will_paginate 中建议的解决方案生产中的错误 NoMethodError(未定义方法 `page' for []:ActiveRecord::Relation)" 和 GitHub 上的相同问题 但它没有用.我还检查了服务器和本地是否安装了相同的 Ruby.
I already tried the solution suggested in "will_paginate error in production NoMethodError (undefined method `page' for []:ActiveRecord::Relation)" and the same question on GitHub but it didn't work. I also checked that server and local have the same Ruby installation.
这在开发中有效.服务器设置是:Ubuntu 12.10、Nginx、独角兽、Capistrano、Ruby 2.0.0p247、Rails 4.0.0.有什么建议吗?
This works in development. The server setup is: Ubuntu 12.10, Nginx, Unicorn, Capistrano, Ruby 2.0.0p247, Rails 4.0.0. Any suggestions?

更新:我重新安装了服务器,现在它可以工作了.不知道为什么...
UPDATE: I reinstalled the server, now it works. Don't know why...
