将其转换为Ruby 1.9哈希

I have the following in the old syntax:

我在旧语法中有以下内容:

render json: [@note.to_json(:include => { :contact => { :except => [:created_at, :updated_at]}}, only: :body)], status: :created, location: [@contact, @note]

How would I do this in the new 1.9 hash syntax? I've tried plenty of different ways but can't seem to understand the syntax. On a side note, I find it rather confusing.

我将如何在新的1.9哈希语法中执行此操作?我尝试了很多不同的方法,但似乎无法理解语法。另外,我发现它相当令人困惑。

Edit: Actually realized I'm already mixing it in with the json: call. Bah! Hate going between to two.

编辑:实际上已经意识到我已经将它与json:call混合在了一起。呸!讨厌两个人之间的差距。

2 个解决方案

#1

I'm not sure where the trouble is, but it converts pretty simply to this:

我不确定麻烦在哪里,但它很简单地转换为:

render json: [@note.to_json(include: { contact: { except: [:created_at, :updated_at]}}, only: :body)], status: :created, location: [@contact, @note]

As an aside, stringing so many nested structures together on one line is bound to be confusing. Break it down so it's readable (and writable).

另外,在一行中将如此多的嵌套结构串在一起肯定会让人感到困惑。将其分解,使其可读(和可写)。

Your example works fine. Only need to change a few more keys

你的例子很好。只需要更换几个键

require 'pp'
pp json: [
    {
      include: { 
        contact: { 
          except: [:created_at, :updated_at]
        }
      },
      only: :body
    }
  ], 
  status: :created, 
  location: %w[contact note]

So, aside from some slight changes to get around objects I don't have access to (@contact and @note) the only ones I changed were

所以,除了一些微小的变化来绕过我无法访问的对象(@contact和@note),我改变的唯一的是

:include => { :contact => { :except =>

include: { contact: { except:

Also, you might look into using rabl for this sort of thing.

此外,您可能会考虑使用rabl进行此类操作。
