Private Params方法不显示表单数据

Question

因此，我正在创建一个playercard，这基本上是一个用户的个人资料页面。我在后端遇到的问题是，我的私有方法playercard_params只返回user_id，并且并不是所有输入到form...although常规参数的信息都显示了创建playercard所需的所有数据。我认为问题可能在前端，但通过向后工作得出的结论是问题在后端。

这是我的控制器：

class Api::V1::PlayercardController < ApplicationController
    before_action :set_user 

    def index      
        if params[:user_id]
            @playercard = @user.playercard
        else
            @playercard = Playercard.all   
        end
        render json: @playercard
    end

    def show
        @playercard = Playercard.find(params[:id])
        render json: @playercard
    end

    def create

            @playercard = Playercard.new(playercard_params)
            binding.pry 
            if @playercard.save
                render json: @user
            else
                render json: {
                error: @playercard.errors.full_messages.to_sentence
                }
            end
    end

    def update
        @playercard = Playercard.find(params[:id])
            if @playercard.update(playercard_params)
                render json: @playercard
            else
                render json: {
                error: @playercard.errors.full_messages.to_sentence
                }
            end
    end

    private 

    def playercard_params
      params.require(:playercard).permit(:player_nickname, :player_height_in_feet, :player_height_in_inches, :player_weight, :player_age, :player_fav_player, :user_id)
    end

    def set_user
        @user = User.find(params[:user_id])
    end

end

我的playercard模型：

class Playercard < ApplicationRecord
    belongs_to :user 

    validates :player_nickname, :player_height_in_feet, :player_height_in_inches, :player_weight, :player_age, :player_fav_player, presence: true
end

和序列化程序，如果有帮助的话：

class PlayercardSerializer < ActiveModel::Serializer
    attributes :id, :player_nickname, :player_height_in_feet, :player_height_in_inches, :player_weight, :player_age, :player_fav_player

    belongs_to :user
  end

以下是我的参数：

<ActionController::Parameters {"playerNickname"=>"white mamba", "playerHeightFeet"=>"6", "playerHeightInches"=>"3", "playerAge"=>"30", "playerWeight"=>"170", "playerFavPlayer"=>"Kobe", "user_id"=>"1", "controller"=>"api/v1/playercard", "action"=>"create", "playercard"=><ActionController::Parameters {"user_id"=>1} permitted: false>} permitted: false>

当我在前端提交表单时，我得到的错误是每个字段都是empty...in the pry，如果我输入playercard_params，只会显示user_id (具有正确的id)

我通过将属性的命名约定与前端和后端结合起来解决了这个问题。它成功了！
