我看过accepts_nested_attributesherehere之前的SO解决方案,但我仍然收到错误消息。我使用React作为前端和Rails后端。我正在尝试创建一个请求发送到计划,并从那里填充到工作人员。Rails 5 accept_nested_attributes_for未经许可的参数错误? (React前端)

我正在使用Rails 5.0.2。我有一个schedule, worker, roster模型。

//Schedule 
    has_many :workers, through: :rosters, dependent: :destroy 
    has_many :rosters 
    accepts_nested_attributes_for :workers #implement accept_nested_attributes here 

//Roster 
    belongs_to :schedule 
    belongs_to :worker 

//Worker 
    has_many :schedules, through: :rosters 
    has_many :rosters 

这里是我的日程表控制器:

def create 
    @schedule = Schedule.new(schedule_params) 
    if @schedule.save 
     render json: @schedule 
    else 
     render json: @schedule, status: :unprocessable_entity 
    end 
    end 
    ... 


private 

    def schedule_params 
    params.permit(:date, :user_id, :workers_attributes => [:worker_id, :name, :phone]) 
    end 

这里是我得到的错误:

app/controllers/schedules_controller.rb:13:in `create' 
Started POST "/api/schedules" for 127.0.0.1 at 2017-05-23 10:30:38 -0700 
Processing by SchedulesController#create as */* 
    Parameters: {"date"=>"2017-05-25T02:00:00.000Z", "user_id"=>1, "workers_attributes"=>{"name"=>"Iggy Test", "phone"=>"1 
23-456-7890"}, "schedule"=>{"date"=>"2017-05-25T02:00:00.000Z", "user_id"=>1}} 
Unpermitted parameter: schedule 
Completed 500 Internal Server Error in 15ms (ActiveRecord: 0.0ms) 



TypeError (no implicit conversion of Symbol into Integer): 

app/controllers/schedules_controller.rb:13:in `create' 

为什么我的要求显示Unpermitted parameter schedule?如果我删除workers_attributes并且只有params.permit(:date, :user_id),它就可以工作。我无法弄清楚为什么错误指向计划。我怎样才能让成功的POST nested_attributes请求导轨?

我使用取做POST请求从侧面反应:

... 
return fetch(`api/schedules`, { 
    method: 'POST', 
    headers: { 
     'Content-Type': 'application/json', 
    }, 
    body: JSON.stringify({ 
     date: date, 
     user_id: 1, 
     workers_attributes: {name: "Iggy Test", phone: "123-456-7890"} 
    }) 

编辑:

从@gabrielhilal以下的答案后,我加入require()params.require(:schedule).permit(:date, :user_id, :workers_attributes => [:id, :name, :phone]),和编辑获取POST上React的结尾有数组对象而不是普通对象:workers_attributes: [{name: "Iggy Test", phone: "123-456-7890"}]。它不再抱怨了,它确实注册新的时间表。然而,新的工人都是nil

#Worker.last shows: 
#<Worker id: 32, name: nil, phone: nil, created_at: "2017-05-23 19:36:09", updated_at: "2017-05-23 19:36:09"> 

对不起,不是说要创建嵌套的问题,但没有人知道为什么它是零?

编辑2:

我得到它的工作排序。

如果我有

def create 
    @schedule = Schedule.new(schedule_params) 
    @workers = @schedule.rosters.build.build_worker 
... 

//schedule_params 
params.permit(:date, :user_id, :workers_attributes => [:id, :name, :pho 

NE])

我能有"Iggy Test"显示,但它会立即创建另一个nil工人。

它创建只是一个nil工人。

您的讯息:

{ 
    "date"=>"2017-05-25T02:00:00.000Z", 
    "user_id"=>1, 
    "workers_attributes"=>{ 
    "name"=>"Iggy Test", 
    "phone"=>"123-456-7890" 
    }, 
    "schedule"=> { 
    "date"=>"2017-05-25T02:00:00.000Z", 
    "user_id"=>1 
    } 
} 

你有两个问题:

  • schedule是不允许的(这就是为什么你看到日志中的消息),但它会被忽略(不会产生任何错误)。
  • workers_attributes应该是一个工人的集合,而不是一个简单的散列,所以这就是为什么你有错误。

你应该得到的东西就像邮局要求如下:

{ 
    "date"=>"2017-05-25T02:00:00.000Z", 
    "user_id"=>1, 
    "workers_attributes"=>{ 
    "0" => { 
     "name"=>"Iggy Test", 
     "phone"=>"123-456-7890" 
    } 
    } 
}

嗨@gabrielhilal,你的答案有助于解决一个问题 - 谢谢!我在我的params方法中添加了require(),现在我有:'params.require(:schedule).permit(:date,:user_id,:workers_attributes => [:id,:name,:phone])''。它修复了'schedule'错误。我还将'workers_attributes'的POST请求更改为对象数组:'workers_attributes:[{name:“Iggy Test”,phone:“123-456-7890”}]'。一个问题是,当我做'Worker.last'时,它显示'nil'属性:'<工号:32,名字:无,电话:无,created_at:“2017-05-23 19:36:09”, updated_at:“2017-05-23 19:36:09”>。你知道为什么吗? – Iggy

看着你的'params'我不认为你需要'params.require(:schedule)',除非你在'schedule'内发送所有东西,比如'{“schedule”=> {“date”=> 2017-05-25T02:00:00.000Z“,”user_id“=> 1,”workers_attributes“=> {...}}}'... – gabrielhilal

当我删除它时,它对最终没有任何影响结果/数据库中保存的内容。 “Worker.last”仍然会为名称和电话显示“nil”。看来Rails没有意识到参数在那里。新创建的Worker只有'id','updated_at'和'created_at'。 – Iggy
