控制器中的include_root_in_json [英] include_root_in_json from controller

问题描述

我正在尝试将结果返回到json不包含根的视图.

I'm trying to return a result to a view where the json does not include the root.

我不想为此模型的所有操作设置此设置，因此正尝试避免设置

I don't want to set this on all actions for this model,so therefore am trying to avoid setting

ActiveRecord.Base.include_root_in_json = false

我希望我能做

@task = Tasks.all
@task.include_root_in_json = false

要获得我需要的响应，但这似乎不起作用，请为#返回一个未定义的方法include_root_in_json =

有没有很好的方法呢?

To get the response I need, but that doesn't seem to be working, returning an 'undefined method include_root_in_json= for #

Is there a nice way of doing this??

推荐答案

现在是一个老问题，但是答案没有更新，并且 Rails 3.2填补了空白(

It's an old question now, but the answers were not updated, and Rails 3.2 filled the gap (Rails source)

现在，使用Rails 3.2，您可以使用:

my_model.to_json(:root => false)

如果您不希望包含根密钥.

if you don't want the root key to be included.

当我刚刚使用数组对其进行测试时，它会变得更好，所以您可以这样做:

It gets even better as I just tested it with an array, so you can do:

Model.all.to_json(:root => true)
