PATCH 获取 json 主体到 Rails答案

【问题标题】：PATCH fetch json body to RailsPATCH 获取 json 主体到 Rails

【问题描述】：

我正在通过fetch 将表单修补到 Rails，但服务器端未正确处理某些属性。

我正在通过 Ruby ruby 2.5.1p57 运行 Rails 5.2.2

当我将数据发布到服务器时，我在浏览器中得到这个console.log 输出：

{id: 10172, weekday: 1, is_only_private: false, is_allow_forced: false, from_time: 08:00, to_time: 09:00, act_ids: [10001, 10002], customer_id: 10000, consultation_id: 10000}

但是在服务器端我可以在控制台上看到这个日志：

Parameters: {"id"=>"10172", "weekday"=>1, "is_only_private"=>false, "is_allow_forced"=>false, "from_time"=>"08:00", "to_time"=>"09:00", "act_ids"=>[10001, 10002], "customer_id"=>"10000", "consultation_id"=>"10000", "timetable"=>{"id"=>"10172", "weekday"=>1, "is_only_private"=>false, "is_allow_forced"=>false, "from_time"=>"08:00", "to_time"=>"09:00"}}

act_ids 在 timetable 属性中消失

我的应用是混合的，它在相同的路由中使用 HTML 和 JSON（甚至是 XML）进行响应。

问题：

这个版本的 Rails 还没解决吗？

解决方法

  def timetable_params
    my_params = params.require(:timetable).permit :weekday,
                                                  :is_only_private,
                                                  :is_allow_forced,
                                                  :from_time,
                                                  :to_time,
                                                  act_ids: []

    my_params[:act_ids] ||= params[:act_ids]

    my_params
  end

【问题讨论】：

这个请求的request.request_parameters 是什么？
@Vasfed: {"id"=>"10172", "weekday"=>1, "is_only_private"=>false, "is_allow_forced"=>false, "from_time"=>"08: 00", "to_time"=>"09:00", "act_ids"=>[10001, 10002], "customer_id"=>"10000", "consultation_id"=>"10000"}
您能否创建一个拼写错误，并在您提交表单时验证参数中显示的内容？您如何在表单上声明 act_ids？
@GuilhermeNunes;错字？？？字段或值中的错字？
@GuilhermeNunes，它是从 ReactJS 组件发送的。但问题不是客户端，而是 Rails 在做magic。

【解决方案1】：

您可能以permit(..., :to_time, :act_ids) 允许它，但应该通过act_ids: [] 允许数组，您已经在timetable_params 代码中拥有它

在干净的应用程序上，这可以正常工作：

#!/usr/bin/env ruby
# frozen_string_literal: true

require "bundler/inline"

gemfile(!!ENV['INSTALL']) do
  source "https://rubygems.org"
  gem 'rails', '5.2.2'
end

require "action_controller/railtie"

class TestApp < Rails::Application
  config.root = __dir__
  config.eager_load = false
  config.session_store :cookie_store, key: "cookie_store_key"
  secrets.secret_key_base = "secret_key_base"

  config.logger = Logger.new($stdout)
  Rails.logger  = config.logger
end

TestApp.initialize!
TestApp.routes.draw{ resources :timetables, only: :update }


class TimetablesController < ActionController::Base
  include Rails.application.routes.url_helpers
  wrap_parameters format: [:json, :xml]

  def update
    render json: timetable_params
  end

  def timetable_params
    params.require(:timetable).permit(:weekday,
                                      :is_only_private,
                                      :is_allow_forced,
                                      :from_time,
                                      :to_time,
                                      act_ids: [])
  end
end

require "minitest/autorun"
require "rack/test"

class BugTest < Minitest::Test
  include Rack::Test::Methods

  def test_returns_success
    payload = {
      "id"=>"10172", "weekday"=>1, "is_only_private"=>false, "is_allow_forced"=>false,
      "from_time"=>"08:00", "to_time"=>"09:00",
      "act_ids"=>[10001, 10002],
      "customer_id"=>"10000", "consultation_id"=>"10000"
    }

    patch "/timetables/10172.json", payload.to_json, { 'CONTENT_TYPE' => 'application/json' }

    assert last_response.ok?
    puts "resp body: #{last_response.body}"
    resp = JSON.parse(last_response.body)

    assert_includes(resp.keys, "act_ids")
  end

  private def app
    Rails.application
  end
end
