未定义的方法"getlocal"显示created_at时? [英] Undefined method "getlocal" when displaying created_at?

问题描述

我将rails 3.2.6和ruby 1.9.3与mongoid gem 3.0一起使用.

i use rails 3.2.6, ruby 1.9.3 with the mongoid gem 3.0.

我想显示数据库条目的created_at字段，但出现以下错误:

i want to display the created_at field of a database entry, but get the following error:

undefined method `getlocal' for "Wed, 25 Apr 2012 15:04:37 -0400":String

这是rails代码:

<dt>Erstellt am:</dt><dd><%= @app.created_at %></dd>

任何建议是什么问题?是否有错误修正?我认为应该可行?

any advice what's the problem? is there a bugfix? should work in my opinion?

提前谢谢！

推荐答案

getlocal是 Time 类的方法，因此可能是混合对象类型的问题.系统期望@app.created_at是Time的实例，不是DateTime .确保created_at的字段类型为DateTime，并且在创建/更新此字段时，请确保您输入的对象也是DateTime对象.

getlocal is a method on the Time class, so it may be a problem of intermixing object types. The system is expecting the @app.created_at to be an instance of Time, not DateTime. Make sure the field type for created_at is DateTime and that when creating/updating this field, make sure the object you put in is also a DateTime object.
