康康条件 [英] Cancan condition

问题描述

我在一个项目中使用CanCan来管理每个项目在每个实体上的不同角色级别。
我正在这样做：

I'm using CanCan in a project to manage different role level on each entity for each project. I'm doing this:

# encoding: utf-8
class Ability
    include CanCan::Ability 
    def initialize(user)
        user ||= User.new            
        if user.is_admin == true
            can :manage, :all
        else 
            can :read, :all
            Project.all.each do |project|
                current_role_name = user.roles.find_by_project_id(project.id).role_name.name
                if current_role_name.eql?'Auteur senior'
                    can :manage, [Project, Introduction, Abstract, Text, Conclusion, Asset, Attachment], :project_id => project.id
                elsif current_role_name.eql?'Auteur junior'
                    can :manage, [Introduction, Abstract, Attachment], :project_id => project.id
                    can :update, Text, :project_id => project.id, :user_level => current_role_name 
                    can :manage, [Asset], :project_id => project.id, :user_level => current_role_name
                elsif current_role_name.eql?'Équipe phylogéniste'
                    can :manage, [Attachment], :project_id => project.id
                    can :manage, [Text, Asset], :project_id => project.id, :user_level => current_role_name
                end
            end    
        end
    end 
end

它在我检查用户角色名时有效，但是在我要使用以下条件之后：

It works when I check the user role_name but after when I want to use condition like this:

can :update, Text, :project_id => project.id, :user_level => current_role_name

此条件无效。我该如何工作？

The condition doesn't have any effect. How can I make it work?

推荐答案

我终于找到了解决方案：

I finally found the solution :

在有关的控制器中，我用load_and_authorize_resource替换了authorize_resource。

In concerned controller I replaced authorize_resource by load_and_authorize_resource and that's it.
