blocks|key|1349726|text|最好的方法是使用数据库表。每一行都应该包含一个关键字和一个值。简单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1349727|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The best way is to use a database table. Each row should contain a keyword and a value. Simples.

blocks|key|1349768|text|你可以使用数据库。创建一个单独的表"settings“，用于存储所需的键/值参数。这种解决方案的缺点是会影响性能(每次需要设置时都会查询DB+)。要解决此问题，您可以像"cache_money“那样通过缓存进行读/写，也可以使用"Rails.cache”创建自己的缓存|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1349769|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You can use database. Create a separate table "settings" that stores key/value parameters you need. The downside of this solution is a performance hit (querying DB every time you need a setting). To fix this issue you could you read/write through cache like "cache_money" or create your own by using "Rails.cache"

I have used <a href="http://agilewebdevelopment.com/plugins/app_config" rel="nofollow noreferrer">app_config</a> gem for a while myself, but it fails with rails 2.3.9 (and probably also with rails 3.x), so I found <a href="http://integrumtech.com/2010/01/application-configuration-or-settings-in-rails-applications/" rel="nofollow noreferrer">this blog</a> that mentions <a href="http://github.com/Squeegy/rails-settings/" rel="nofollow noreferrer">rails-settings</a> and <a href="http://github.com/markbates/configatron/" rel="nofollow noreferrer">configuration</a>, rails-settings stores values in DB, but configuration have namespaces built-in. I haven't tried them, but I think I will switch to rails-settings.

I notice now that <a href="http://github.com/ledermann/rails-settings" rel="nofollow noreferrer">the branch of rails-settings that Yi-Ru Lin mentions</a> seems to be more featureful than the other <a href="http://github.com/Squeegy/rails-settings/" rel="nofollow noreferrer">rails-settings</a>

blocks|key|1134592|text|您可以使用rails+gem，它是rails-settings+gem的一个分支(在另一个答案中由Yi-Ru+Lin链接)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1134593|设置完成后，您将能够执行以下操作：|1134594|Setting.foo+=+123

You could use the <a href="https://github.com/huacnlee/rails-settings-cached">rails-settings-cached</a> gem which is a fork of the rails-settings gem (linked by Yi-Ru Lin in another answer).

Once setup, you'll be able to do things such as:

<pre><code>Setting.foo = 123
Setting.foo # returns 123
</code></pre>

You can also manage settings on models, ex:

<pre><code>user.settings.color = :red
user.settings.color # returns :red
</code></pre>

blocks|key|1134704|text|对于Rails4，如果您使用的是postgresql，则可以使用HStore，它就像一个可序列化的属性，但您可以使用它进行SQL查询。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1134705|对于Rails3，您可以使用activerecord-postgres-hstore+gem。|1134706|entityMap|0|LINK|mutability|MUTABLE|url|http://mikecoutermarsh.com/using-hstore-with-rails-4/|1|https://github.com/diogob/activerecord-postgres-hstore/^0|W|6|0|0|E|S|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

For rails 4, if you are using postgresql, you can use <a href="http://mikecoutermarsh.com/using-hstore-with-rails-4/" rel="nofollow">HStore</a>, which is just like a serializable attribute, but you do SQL queries with it.

For rails 3, you can use <a href="https://github.com/diogob/activerecord-postgres-hstore/" rel="nofollow">activerecord-postgres-hstore</a> gem.

I have a relatively simple Rails app and I would like to store various configuration settings that administrator users can change whilst the application is running, for example, allowing comments on posts or changing the display format of the date.

I know I can store constants etc in the environment.rb file, however these appear to be loaded only when the server is restarted.

Is there an alternative place I can define this information or would it be better to keep it in the database?

Any advice appreciated.

Thanks.

我有一个相对简单的Rails应用程序，我想存储管理员用户可以在应用程序运行时更改的各种配置设置，例如，允许对帖子进行评论或更改日期的显示格式。我知道我可以在environment.rb文件中存储常量等，但是这些似乎只有在服务器重新启动时才会加载。是否有其他地方可以定义此信息，或者最好将其保存在数据库中？任何建议都很感谢...
