ActionController::ParameterMissing（引數丟失或值為空：供應商

我正在嘗試在我的 Rails 應用程式上使用 Postman 發帖，但我收到一個問題：

ActionController::ParameterMissing (param is missing or the value is empty: vendor
Did you mean?  vendor_data
               action
               quote_type
               controller):

這是我controller呼叫引數的檔案：

def create_vendor_params
    params.require(:vendor).permit(
      :vendor_id, :quote_type, :first_name, :last_name, :email, :phone_type, :phone, :request_type, :address1, :address_city, :address_state, :address_zip, :DOB
    )
  end

這是我從 Postman 發送的資料。現在我不確定是不是因為renter_data它嵌套在我的params permit：

{
    "vendor_id": 2,
    "quote_type": "renter",
    "renter_data": {
        "first_name":"Tony",
        "last_name":"Stark",
        "email":"tony@starkindustries",
        "phone_type":"mobile",
        "phone":"6504881234",
        "request_type":"renter",
        "address1":"123 Main Street",
        "address_city":"Palo Alto",
        "address_state":"CA",
        "address_zip":"94301",
        "DOB":"1990-07-22"
    }
}

這個問題是因為里面的嵌套資料renter_data嗎？如果是，我該如何嵌套它？

編輯

當我發帖時，我在請求末尾看到一個空物件：

Processing by Api::V2::LeadController#create as */*
      Parameters: {"vendor_id"=>2, "quote_type"=>"renter", "renter_data"=>{"first_name"=>"Tony", "last_name"=>"Stark", "email"=>"tony@starkindustries", "phone_type"=>"mobile", "phone"=>"6504881234", "request_type"=>"renter", "address1"=>"123 Main Street", "address_city"=>"Palo Alto", "address_state"=>"CA", "address_zip"=>"94301", "DOB"=>"1990-07-22"}, "vendor"=>{} <---HERE }

這是為什么？

uj5u.com熱心網友回復：

有兩個問題：首先，強引數期望輸入嵌套在vendor. 其次，強引數不期望嵌套renter_data散列。

要在查詢中解決此問題，請將請求資料的結構更改為：

{
  "vendor": {
    "vendor_id": 2,
    "quote_type": "renter",
    "first_name":"Tony",
    "last_name":"Stark",
    "email":"tony@starkindustries",
    "phone_type":"mobile",
    "phone":"6504881234",
    "request_type":"renter",
    "address1":"123 Main Street",
    "address_city":"Palo Alto",
    "address_state":"CA",
    "address_zip":"94301",
    "DOB":"1990-07-22"
  }
}

如果您想保留嵌套renter_data哈希，那么您必須更改像 Paarth Agrawal 已經建議的強引數。但是你仍然需要將所有內容嵌套在vendor.

uj5u.com熱心網友回復：

這是 create_vender_params 函式中嵌套強引數的概念，您必須添加更多允許的引數

params.require(:vendor).permit(
  :vendor_id, :quote_type, renter_Data: [:first_name, :last_name, :email, :phone_type, :phone, :request_type, :address1, :address_city, :address_state, :address_zip, :DOB])

uj5u.com熱心網友回復：

vendor_table 有一些欄位vendor_id, quote_type, first_name, last_name, email,phone_type,phone, request_type, address1,address_city,address_state, address_zip,DOB。

def create_vendor_params
 params.require(:vendor).permit(
  :vendor_id, :quote_type, :first_name, :last_name, :email, 
  :phone_type,:phone, :request_type, :address1, :address_city, 
  :address_state,:address_zip, :DOB)
end

 "vendor": {
    "vendor_id": 2,
    "quote_type": "renter",
    "first_name":"Tony",
    "last_name":"Stark",
    "email":"tony@starkindustries",
    "phone_type":"mobile",
    "phone":"6504881234",
    "request_type":"renter",
    "address1":"123 Main Street",
    "address_city":"Palo Alto",
    "address_state":"CA",
    "address_zip":"94301",
    "DOB":"1990-07-22"
  }

def create 
 @vendor = Vendor.new(create_vendor_params)
 if @vendor.save
    render json: {'Success' }
 else
    render json: {error: @vendor.errors}
 end
end
