Question

以下是我在控制器中提供创建方法的JSON

{
   "sex":null,
   "money":281,
   "networth":281,
   "property":[
      {
         "houses":"1",
         "id":"5",
         "father":"Jerry",
         "mother":"Tanya",
         "height":281,
         "children":2,
         "pets":24
      },
      {
         "houses":"3",
         "id":"5",
         "father":"Rob",
         "mother":"Anne",
         "height":726,
         "children":1,
         "pets":55
      }
   ]
}

我的控制器如下：

  def create
     person = Person.new
     person.houses = person_params[:houses]
     person.father = person_params[:father]
     person.save
  end


  private

   def person_params
    params.permit(person: []).require(:person)
   end

我无法找到如何从传递的JSON中提取数据，假设我想在JSON中保存数据库中的房屋实例或任何其他值，我将如何提取该数据？我想我的person_params有问题

您需要格式化您的json格式，如下所示

{ "person": { "money": "281", "address": "123 Carrot Street" } }

您的create方法将收到此格式的参数

params[:person] as { "money" => "281", "address" => "123 Carrot Street" }

这是link document for official guide
