将查询字符串中的多维数组传递给Rails中的控制器 [英] Pass Multidimensional Array in Query String to Controller in Rails

问题描述

将多维数组传递到rails控制器时，似乎无法正确解析。我这样做错了吗？

When passing a multidimensional array to a rails controller, it does not seem to parse correctly. Am I doing it wrong?

url: http://localhost:3000/people?sort[][]=lastname&sort[][]=1&sort[][]=firstname&sort[][]=1
params: {
          "sort" => [
        [0] nil,
        [1] nil,
        [2] nil,
        [3] nil
    ],
        "action" => "index",
    "controller" => "people"
}

应为：

params: {
          "sort" => [
        [0] => [
          [0] => 'lastname',
          [1] => 1
        ],
        [1] = > [
          [0] => 'firstname',
          [1] => 1
        ]
    ],
        "action" => "index",
    "controller" => "people"
}

推荐答案

Rails doesn'在查询字符串中支持多维数组。

Rails doesn't support multi-dimensional arrays in the query string.

它支持一维数组：

http://localhost:3000/people?sort[]=lastname&sort[]=firstname
# params[:sort] == ['lastname', 'firstname']

并支持散列：

http://localhost:3000/people?sort[lastname]=asc&sort[firstname]=desc
# params[:sort] == {:lastname => 'asc', :firstname => 'desc'}
