CanCan未初始化的常数Ability :: CanCan

问题描述

您知道我在这里可能做错了什么吗？我知道说能力不是可以的吗？ ：manage，all;但是我只是想开始使用CanCan。

Any idea what I could be doing wrong here? I know it's not very useful to say ability.can? :manage, all; however I'm just trying to get started with CanCan.

我确实拥有gem，并且运行了generate cancan：ability。

I do have the gem, and have run generate cancan:ability.

谢谢。

错误和代码：

未初始化的常数Ability :: CanCan
提取的源（第4行附近）：

uninitialized constant Ability::CanCanExtracted source (around line #4):

1: 
2: <% if current_user %>
3:     <p>Currently logged in as <strong><%= current_user.email %></strong></p>
4:     <% current_ability = Ability.new(current_user) %>
5:     <%if can? :manage, :all %>
6:      <p>Hey Buddy, You're Authorized ;)</p>
7:     <% end %>

推荐答案

我收到此错误是因为我的Gemfile放置了CanCan要求

I received this error because my Gemfile placed the CanCan requirement in a group that was not being loaded in the test environment.

请尝试检查您的CanCan要求是否已在运行的环境中加载。此要求将CanCan加载到默认组中：

Try checking to see that your CanCan requirement is loaded in the environment you're running. This requirement will load CanCan in the default group:

# project_root/Gemfile
source 'http://rubygems.org'

gem 'rails', '3.1.0'
gem 'cancan'
