从Rails 2.3.6开始不推荐使用overwrite_params-接受的解决方法？ [英] overwrite_params deprecated as of Rails 2.3.6 -- Accepted Workaround?

问题描述

因此，从Rails 2.3.6开始，似乎已弃用 overwrite_params 。有没有一种通常被认为是最佳实践的合适的解决方法？

So, it looks like overwrite_params is deprecated as of Rails 2.3.6. Is there a suitable workaround that is generally accepted as best-practice?

例如，我曾经能够执行以下操作（我认为这非常有用） ：

For example, I used to to be able to do the following (which I thought was quite useful):

url_for(:overwrite_params => {:page => 1})

我在网上看到了以下解决方案...这是新方法吗？

I've seen the following solution mentioned online ... is this the new way to do it?

url_for(request.params.merge(:page => 1))

谢谢您的帮助。

推荐答案

我实际上只是在Railscast一集中看到了这一点： http://railscasts.com/episodes/240-search-sort- paginate-with-ajax

I actually just saw this mentioned in a Railscast episode: http://railscasts.com/episodes/240-search-sort-paginate-with-ajax

他基本上使用params.merge来建议您所说的话。请注意，您无需说出request.params，params就足够了。另外，如果您使用的是link_to，则可能不需要url_for。换句话说，如果您有：

He suggests basically what you said, using params.merge. Note that you don't need to say request.params, params is sufficient. Also if you're using link_to, then you may not need url_for. In other words, if you have:

link_to title, url_for(params.merge(:page => 1))

然后可以说

link_to title, params.merge(:page => 1)
