Rails 3:将时区设置为当前用户时区 [英] Rails 3: setting the timezone to the current users timezone

问题描述

我把它放在应用程序控制器中:

I put this in Application Controller:

before_filter :set_timezone 

def set_timezone  
Time.zone = current_user.time_zone 
end  

但我总是收到错误:

undefined method time_zone for #<User:0xa46e358>

我就是不知道为什么...

and I just don't know why...

希望有人能帮忙

推荐答案

Max -- the ryandaigle.com 文章 您提到了 这篇文章，您需要在其中创建迁移以将time_zone"作为属性添加到用户

Max -- the ryandaigle.com article you mentioned links to this writeup where you need to create a migration to add "time_zone" as an attribute to the user

(本文来自文章，采用 rails 2.x 语法)

(this is from the article, in rails 2.x syntax)

$ script/generate scaffold User name:string time_zone:string
$ rake db:migrate

稍后

<%= f.time_zone_select :time_zone, TimeZone.us_zones %>

这就是您的 .time_zone 返回 method_missing 的原因——您还没有将 time_zone 存储在用户身上.

That's why your .time_zone is returning a method_missing -- you haven't stored the time_zone on the user yet.
