Question

我无法保存模特。

公司模型：文件模型= 1：N

使用JSON，我想知道cyaan获得文档的参数。但我不明白。它能理解哪里不好吗？请告诉我。

发布数据

{
  "name": "name",
  "address": "asd",
  "phone": "0394564",
  "fax": "168465",
  "mail": "mailtest",
  "documents":[{
    "name": "name",
    "address": "asd",
    "phone": "58465",
    "fax": "543543"
},{
    "name": "test",
    "address": "asd",
    "phone": "5452452",
    "fax": "24534535"
}]
}

代码 [模型] company.rb

class Company < ActiveRecord::Base 
  has_many :documents
  accepts_nested_attributes_for :documents
end

[模型] document.rb

class Document < ActiveRecord::Base
  belongs_to :company
end

[控制器] company_controller.rb

def create
  @company = Company.new(company_params) 

  if @company.save 
    render json: @company, status: :created
  else
  render json: @company.errors, status: :unprocessable_entity
end

end

def company_params 
  params.require(:company).permit(:name, :address, :phone, :fax, :mail, documents_attributes: [:name])
end

Answer 1

只要您在强对手中要求对象，就必须声明对象。

{"company"=>{"name"=>...}}

Rails将捕获“公司”值并允许它们。

这里有同样的问题：

Why isn't my Rails API saving anything to the database?

编辑：

在你的参数中：

..
"documents":[{
..

在许可证中：

   documents_attributes:

也许这就是原因。
