Rails 使用camelCase 渲染json 对象 [英] Rails render json object with camelCase

问题描述

我在一个简单的 Rails API 中有以下控制器代码:

class Api::V1::AccountsController <应用控制器定义索引渲染 json:Account.all结尾高清秀开始渲染 json: Account.includes(:cash_flows).find(params[:id]), include: :cash_flows救援 ActiveRecord::RecordNotFound =>电子头 :not_found结尾结尾结尾

问题在于，生成的 json 格式如下:

<代码>{编号:2，name: '简单账户',现金流: [{编号:1，金额:34.3，description: '简单描述'},{编号:2，金额:1.12，描述:'其他描述'}]}

我需要我生成的json是camelCase('cashFlows'而不是'cash_flows')

提前致谢！！！

解决方案

按照 @TomHert 的推荐，我使用了 JBuilder 和可用的配置:

<块引用>

可以使用 key_format! 自动格式化键，这可用于将键名从标准 ruby​​_format 转换为驼峰式:

json.key_format！骆驼::降低json.first_name '大卫'# =>{名字":大卫"}

<块引用>

您可以使用类方法 key_format 全局设置它(例如从您的 environment.rb 中):

Jbuilder.key_format camelize::lower

谢谢！！！

I have the following controller code in a simple Rails API:

class Api::V1::AccountsController < ApplicationController
  def index
    render json: Account.all
  end

  def show
    begin
      render json: Account.includes(:cash_flows).find(params[:id]), include: :cash_flows
    rescue ActiveRecord::RecordNotFound => e
      head :not_found
    end
  end
end

The problem with this is that, the generated json have the format:

{
  id:2,
  name: 'Simple account',
  cash_flows: [
    {
      id: 1,
      amount: 34.3,
      description: 'simple description'
    },
    {
      id: 2,
      amount: 1.12,
      description: 'other description'
    }
  ]
}

I need that my generated json is camelCase('cashFlows' instead of 'cash_flows')

Thanks in advance!!!

解决方案

Following the recommended by @TomHert, I used JBuilder and the available config:

Keys can be auto formatted using key_format!, this can be used to convert keynames from the standard ruby_format to camelCase:

json.key_format! camelize: :lower
json.first_name 'David'

# => { "firstName": "David" }

You can set this globally with the class method key_format (from inside your environment.rb for example):

Jbuilder.key_format camelize: :lower

Thanks!!!
