Rails:对于每个模型，始终包含带有created_at的毫秒数 [英] Rails: always include the milliseconds with created_at for every model

问题描述

如何修改Rails应用程序，使其始终在模型的created_at字段中包含毫秒信息?

How do I modify my Rails app to always include the milliseconds information with the created_at field of my models?

This question has the answer for how to do it for an individual model, but I want to do it globally.

例如，当我检索所有Item模型(通过用GET击/items)时，将获得以下JSON:

For example, when I retrieve all my Item models (by hitting /items with a GET), I get the following JSON:

[{"created_at":"2011-08-07T23:42:15Z","updated_at":"2011-08-07T23:42:15Z","id":180,"user_id":6,"content":"test"}]

但是请注意，created_at字段没有有关创建该毫秒的信息.如何在我的所有模型中包含它?

But note that the created_at field doesn't have any information about the millisecond that it was created. How do I include that for all my models?

推荐答案

我能够使用任何人都知道如何在所有型号上做到这一点吗?

Anyone know how to do it for all models?
