Question

我在同一页面上有注册和登录表单，并希望在此页面上显示任何注册和登录错误，例如“电子邮件已存在”。我使用this solution自定义了注册控制器，并创建了custom DeviseFailure class，因此登录时出现的错误会重定向回到此页面。

我有两个问题：

如果由于表单中的错误而导致注册失败（例如，输入已注册的电子邮件地址），然后我尝试登录，我就会

内部服务器错误 - inGET，接受的HTTP方法是OPTIONS，GET，HEAD，POST，PUT，DELETE，TRACE，CONNECT，PROPFIND，PROPPATCH，MKCOL，COPY，MOVE，LOCK，UNLOCK，VERSION-CONTROL，REPORT，CHECKOUT ，CHECKIN，UNCHECKOUT，MKWORKSPACE，UPDATE，LABEL，MERGE，BASELINE-CONTROL，MKACTIVITY，ORDERPATCH，ACL，SEARCH，MKCALENDAR和PATCH。

如果我然后重新加载重定向正确发生。我不知道如何解决这个错误。

如何仅针对登录表单或仅针对注册表单捕获错误？目前错误显示两次 - 每个表单一次。
