我在一个简单的Rails API中有以下控制器代码:
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
这个问题是,生成的json具有以下格式:
{
id:2,
name: 'Simple account',
cash_flows: [
{
id: 1,
amount: 34.3,
description: 'simple description'
},
{
id: 2,
amount: 1.12,
description: 'other description'
}
]
}
我需要我生成的json是camelCase('cashFlows'而不是'cash_flows')
提前致谢!!!
我想创建一个类似于此的Elixir代码:
def infinite_loop(created_workers \\ []) do
case next_from_queue do
{:ok, queue_msg} ->
new_worker = Task.async(fn -> crawling(queue_msg) end)
infinite_loop([new_worker | created_workers])
{:error, :empty} ->
created_workers.map(&Task.await/1)
end
end
假如说:
crawling功能将创建另一个3Taskcrawling 工人都可以跑3秒钟queue可能有上百万的消息我怎么知道Elixir上并行处理的限制是什么？如何管理它不破坏？
我正在生成一些自动规范，并且我希望在期望成功的时候有一个自定义的成功消息。例如，我想要这样的报告：
Opportunity
.rating_info
where the real estate kind is Monoambiente
and there aren't assigned values
is 0
when there are multiple combinations
is has the expected value(run 45 different combinations)
