My use case starts from something a lot like this; a team uses a central repository (in my case it is subversion, but I believe if it were git the issue would be the same), and some of the files are member-private (Django local settings files, IDE private project preferences etc). While the private file should remain private -- that is, I don't want changes I make to it to be pushed or dcommitted -- I do want the …
这很简单,我想通过调用DataMapper来处理正常的[show]请求,就像我在Merb中所做的那样.
使用ActiveRecord我可以这样做:
class PostsController
def show
@post = Post.get(params[:id])
@comments = @post.comments unless @post.nil?
end
end

它通过捕获资源的异常来处理404.
相反,DataMapper不会自动执行此操作,因此我现在正在使用此解决方案解决此问题:[在答案中移动]
有可能告诉控制器在not_found函数内停止吗?
我正在开始一项活动,宁愿有一个淡入淡出的淡入淡出startActivity()和淡出淡出finish().我怎样才能在Android SDK中解决这个问题?

作为背景,我不久前给出了这篇文章的答案:
它无意中开始了一个关于指针与C++中的数组的长链注释链,因为我试图过度简化并且我做了"数组是指针"的声明.虽然我的最终答案听起来相当不错,但只是在对我收到的很多评论进行了大量编辑之后.
这个问题并不是拖钓诱饵,我理解指针和数组不是一回事,但C++语言中的一些可用语法肯定会使它们在很多情况下表现得非常相似.(仅供参考,我的编译器已i686-apple-darwin9-g++-4.0.1开启OS X 10.5.8)
例如,这段代码编译并运行就好了(我意识到这x[8]是一个潜在的分段错误):
//this is just a simple pointer
int *x = new int;
cout << x << " " << (*x) << " " << x[8] << endl; //might segfault
