Question

我的应用程序使用Rails，Activeadmin和Ransack。

最近我注意到日期过滤工作不正常。我还检查了与Activeadmin分开的控制器，问题仍然存在。这可能是一个Ransack问题吗？

日志表明params正确传递，它们仍然在URL中。计数工作正常，但实际查询不会发生。有什么想法可以在这里发生什么？我最近升级到Ruby 2.2，但我不确定这是否相关。

以下是参数：

Started GET "/admin/users?utf8=%E2%9C%93&q%5Bcreated_at_gteq%5D=2015-11-01&q%5Bcreated_at_lteq%5D=2015-11-30&q%5Brole_contains%5D=read&commit=Filter&order=id_desc" for 50.17.182.190 at 2015-11-13 05:16:52
 +0000

在这里，您可以看到SQL查询中从未使用过日期：

User Load (0.8ms)  SELECT  "users".* FROM "users"  WHERE ("users"."role" ILIKE '%read%')  ORDER BY "users"."id" desc LIMIT 30 OFFSET 0

完整日志如下：

我刚遇到这样的问题。事实证明，我是以美国格式（mm-dd-yyyy）提交日期，但服务器将其解释为yyyy-mm-dd或dd-mm-yyy，这会导致您的日期无提示失败并返回nil一次导轨/ ruby处理它。我安装了american_date gem并修复了它。

Ruby内部（在Date和DateTime类）用于处理美国日期很好，但社区已经决定（可能是正确的）美式日期并不是很好的默认对于国际用户。所以这可能是你在升级ruby之后注意到这一点的原因。

日期过滤不适用于Rails - Ransack，Activeadmin
