Question

我想允许使用queries参数。但是我只知道它是一个带有嵌套哈希的哈希。我不知道里面有什么钥匙。它可以例如看起来像这样：

在继续之前，我需要解析参数：

params[:queries] = JSON.parse(params[:queries])
# =>
# {
#   "query1": {
#     "query": {
#       "order_number": {
#         "$in": ["1", "2"]
#       },
#       "name": "Batman"
#     },
#     "projection": {
#       "_id": 1,
#       "order_number": 1
#     },
#     "sort": {
#       "order_number": 1
#     }
#   },
#   "query2": {
#   }
# }

解析之后，我想允许它，但是params.permit([{queries: {}}])不允许所有嵌套的哈希。

那么我如何简单地允许queries参数包含任何嵌套内容？
