Question

我有2个数组，我想将它们组合在一个应该返回嵌套JSON的数组中。第一个是清洁剂，它返回：

{
  "response": [
    {
      "id": 1,
      "first_name": "Fernando",
      "last_name": "Gomez",
      "avg_rating": "4.5"
    }  
  ]
}

第二个是来自客户的评论它返回客户的名称，评论和评级：

{
  "response": [
    {
      "id": 1,
      "score": 4,
      "comment": "Comment",
      "first_name": "John Doe"
    }
  ]
}

所以，我试图拉链它们并循环遍历它们。这是我的代码：

cleaners.zip(reviews).each do |cleaner, review|
  if cleaner.id == review.id
   test['first_name'] = cleaner.first_name
   test['last_name'] = cleaner.last_name
   test['rating'] = review.score
   test['comment'] = review.comment
   test['client_name'] = review.first_name
  end
end

结果是：

{
  "response": {
    "first_name": "Fernando",
    "last_name": "Gomez",
    "rating": 4,
    "comment": "Comment",
    "client_name": "John Doe"
  }
}

但我的结果必须嵌套，因为有些清洁工会有很多评论。它必须是这样的：

{
  "response": {
    "first_name": "Fernando",
    "last_name": "Gomez",
    "score_from_client": [
                {
                  "rating": 4,
                  "comment": "Comment",
                 "client_name": "John Doe"
                }
                ]
  }
}

以下是问题的答案：）

unless cleaners.nil?



cleaner_ids = []
  cleaners_reviews = []

  cleaners.each do |cleaner|
    cleaner_review = { 
      id:  cleaner.id,
      avg_rating:  cleaner.avg_rating,
      first_name:  cleaner.first_name,
      last_name:  cleaner.last_name,
      ratings: []
    }
    cleaners_reviews << cleaner_review
    cleaner_ids << cleaner.id
  end

  reviews = Cleaner.get_cleaner_reviews(dates, cleaner_ids)

  unless reviews.empty?
    i = 0
    reviews.each do |review|
      cleaners_reviews[i][:ratings] << review
      i += i
    end
  end

  return cleaners_review
