Создание структуры JSON Coldfusion с вложенными массивами структур

Question

В ColdFusion (REST/C, я пытаюсь заполнить структуру, называемую «магазины»). Вложенная внутри - массив отчетов и вложенная внутри отчетов - это массив изображений. вложенные внутри отчетов - это массив Вопросов, а вложенный в «Вопросы» - это массив ответов.

ПРИМЕЧАНИЕ. В каждом магазине могут быть несколько отчетов, и каждый отчет может содержать несколько изображений, а также несколько вопросов, и каждый вопрос может иметь несколько ответов.

окончательный JSON должен выглядеть следующим образом ...

CFDUMP не выглядит плохо, но в результате JSON является неприемлемым.

CFDUMP

В противном случае JSON (частичный сниппета). Собственный JSON будет содержать массивы структур. Как создать правильный массив структур в CF или CFSCRIPT

Например, мне не нужно видеть «хранилище [3]» и «отчет [2]» в JSON, это должно быть просто массив структур с именем: пары значений.

{"stores":{"store[3]":{"reports":{"report[3]":{"report_data":{"questions":{"q[1]":{"question_stock":"N","question":"Did you complete the training... 

ЗАКЛЮЧЕНИЕ Чтобы добавить к путанице, есть несколько запросов, с несколькими петлями, чтобы раздобыть все данные, необходимые для заполнения массивов. Я не могу обвести вокруг себя голову. Спасибо за любую помощь, которую вы могли бы предоставить, чтобы указать мне в правильном направлении.

Answer 1

I shouldn't have to see "store[3]" and "report[2]" in the JSON Но это ваш код! Начните с простого и попытаться понять, как это работает:

<cfset myStru = { stores = [] }> 
<cfset myTmpStru = { storeid = 101, storename = "STORE101", reports = [ ] }> 
<cfset myTmpStru2 = { reportid = 201, reportname = "REPORT201", pics = [ ] }> 
<cfset ArrayAppend(myTmpStru.reports, myTmpStru2)> 
<cfset ArrayAppend(myStru.stores, myTmpStru)> 

Answer 2

как I петлю вокруг результатов Кер (х годов) и заполнить массивы без использования store[1], store[2], и т.д.

на основе комментариев, несколько других советов о функции:

1. I Тхи nk вы приближаетесь к нему назад :) Нет необходимости отслеживать позиции массива. Каждый раз, когда вы выполняете цикл, создайте новую структуру «store» («report» и т. Д.). Затем заполните тем, что при необходимости. По завершении добавьте текущий объект в соответствующий массив или структуру и забудьте об этом. Поскольку вы работаете только с одним «магазином», «отчет» и т. Д. За раз (то есть с текущим), нет необходимости беспокоиться о позициях или индексах.

   <cfset storeArray = []> 
   <cfloop ...> 
   
       <!--- create a new store object ---> 
       <cfset currStore = { "reports" = [] }> 
       ... populate .... 
   
       <cfloop ....> 
        <!--- create a new report object ---> 
        <cfset currReport = { "pics" = [], "questions" = [] }> 
        ... populate .... 
   
        <!--- add to array ---> 
        <cfset arrayAppend(currStore.reports, currReport)> 
   
       </cfloop> 
   
       <!--- add to array ---> 
       <cfset arrayAppend(storeArray, currStore)> 
   
   </cfloop> 
   

2. Не напрямую связана с вопросом, но всегда использовать cfqueryparam.Помимо обеспечения защиты от вторжений в sql, это также помогает повысить производительность запроса, когда один и тот же оператор выполняется несколько раз, как в данном случае.

3. Не забудьте локализовать ВСЕ функциональные локальные переменные. Это включает в себя имена запросов, переменные индекса цикла - любые переменные, используемые только внутри функции. Определение этих переменных с помощью VAR или LOCAL гарантирует, что они не просачиваются в общую область variables, что может вызвать странные и трудные способы воспроизведения ошибок при определенных условиях (просто выполните поиск по ColdFusion + race conditions).
