我要说的是,我已经建立了一个用户,他们把一些意见留给了我的现场,然后我用“@user”删除。 销毁。
现在,当我发表评论时,它 errors倒了错误,因为“......用户对于他们撰写的评论是没有的”。
考虑到:
我通常使用一个叫做的栏目——at 。 然后界定一个模型方法archive,该模型将<代码>删除_at与目前时间和节省费用联系起来。 然后是,(删除_at IS NUL )(或,如果你爱,则该模型的过失范围为。 同我一样。
我使用的是我的用户模式。 即便在每种模式中,我也能从中抽取这种功能,但我只想在模型中登上archived_by :deleted_at。 在你看来,可能有一些地方需要检查,看要求的记录是否存档/删除,但大部分是简单而棘手的解决办法。 将记录从删除/存档后重现为简单格式:record.deleted_at = nil(或record.archive(false)/record.unarchive 。
为此,请在表一中提出,将<代码>删除>:at 栏索引。
另一种简单的想法是,将一个称为可装药的风气场,并用一个关切来界定范围(如)。
因此,你们都需要创立一种控制器行动,它拥有一种@用户。 !! (我将对拖拉机实行禁制),用户被软化。
