has_permission_on 具有声明性授权，非属性条件

发布于 2024-11-17 16:00:07 字数 181 浏览 2 评论 0原文

如果我的应用程序中设置了会话变量，我想授予特定操作授权。我不知道该怎么做。比如：

has_permission_on :admin, :to => :action do
  true if session[:key]
end

我不明白如何完成这个基本任务。任何帮助表示赞赏。

原文

I want to give authorization to a specific action if a session variable is set in my app. I can't figure out how to do this. Something like:

has_permission_on :admin, :to => :action do
  true if session[:key]
end

I don't understand how to accomplish this basic task. Any help appreciated.

您想在函数上使用 before_filter 例如

before_filter :authorize, :only => :action

private
def authorize
unless session[:key]
flash[:notice] = "Cannot do this"
redirect_to(:controller => "controller", :action => "otheraction")
end

You want to use a before_filter on the function e.g.

before_filter :authorize, :only => :action

private
def authorize
unless session[:key]
flash[:notice] = "Cannot do this"
redirect_to(:controller => "controller", :action => "otheraction")
end
