What flash message types are available in Rails?
提问by cjm2671
So far I've got:
到目前为止，我有：
- :notice
- :alert
- :error
- ：注意
- ：警报
- ：错误
but is there definitive list, that can be used in place, such as in redirect_to path, :error => "Oh no!"?
但是是否有明确的列表，可以就地使用，例如在redirect_to path, :error => "Oh no!"？
采纳答案by Hauleth
No, as a flash type you can use any symbol, even your own.
不，作为一种闪光类型，您可以使用任何符号，甚至是您自己的符号。
回答by Steve Grossi
Hauleth is correct that you can use any symbol, but right now, :noticeand :alertare the only ones you can pass directlyinto redirect_to(according to flash.rb in Rails source), as you specifically mention:
Hauleth是正确的，你可以使用任何的象征，但现在，:notice并且:alert是可以传递的唯一直接进入redirect_to（根据在Rails的源flash.rb），为您特别提到：
redirect_to path, :error => "Oh no!" # Will not work
If you want a different flash type such as :error(or :success), you must pass those in through the :flashkey, like so:
如果您想要不同的 flash 类型，例如:error(或:success)，则必须通过:flash键传递它们，如下所示：
redirect_to path, :flash => { :error => "Oh no!" }
For information on how to register your custom flash types so that, like :noticeand :alert, you can pass them directly in to redirect_to, see this StackOverflow Q&A: https://stackoverflow.com/a/3848759/995663
有关如何注册自定义的闪存类型，这样，类似的信息:notice和:alert，您可以直接通过他们redirect_to，看到这个StackOverflow的Q＆A：https://stackoverflow.com/a/3848759/995663
Update:According to this commit, it seems Rails 4 will make this easier by allowing you to register custom flash types by calling add_flash_types :errorin ApplicationController.
更新：根据此提交，似乎 Rails 4 将允许您通过调用add_flash_types :errorApplicationController来注册自定义 Flash 类型，从而使这变得更容易。
