I sent the parameter from Postman. Parameters are successfully sent to Server. but Controller doesn't save it into Database.

I tried to make initializer in User.rb but it doesn't works with initializer "Parameter is missed. given 1, expected 3" error message.

So I erased initializer and Server can receive the parameters well but cannot save in database.

User.rb

class User < ApplicationRecord  

  attr_accessor :email, :pwd, :usertype  



=begin  

 def initialize(email, pwd, usertype) @email=email, @pwd=pwd, @usertype=usertype end=end  



  VALID_EMAIL_REGEX = /A[w+-.]+@[a-zd-.]+.[a-z]+z/i  

  validates :email, presence: true, uniqueness: { case_sensitive: false},  

  format: {with: VALID_EMAIL_REGEX}, length: {minimum:3, maximum:50}  



  validates :pwd, presence: true, length: {minimum:3, maximum:25}  



  has_many :bookings  





end

users_controller.rb

class UsersController < ApplicationController  

  before_action :set_user, only: [:show, :update, :destroy]  



  # GET /users  

 # GET /users.json  def index  

  @users = User.all  

  end  



  # GET /users/1  

 # GET /users/1.json  def show  

  end  



  # POST /users  

 # POST /users.json  def create  

  @user = User.new(user_params)  



    if @user.save  

      render :show, status: :created, location: @user  

  else  

  render json: @user.errors, status: :unprocessable_entity  

  end  

 end  

  # PATCH/PUT /users/1  

 # PATCH/PUT /users/1.json  def update  

  if @user.update(user_params)  

      render :show, status: :ok, location: @user  

  else  

  render json: @user.errors, status: :unprocessable_entity  

  end  

 end  

  # DELETE /users/1  

 # DELETE /users/1.json  def destroy  

  @user.destroy  

  end  



  private  

  # Use callbacks to share common setup or constraints between actions.  

  def set_user  

  @user = User.find(params[:id])  

    end  



  # Never trust parameters from the scary internet, only allow the white list through.  

  def user_params  

  params.require(:user).permit(:email, :pwd, :usertype)  

      # params.permit!  

  end  

end

As you can see, server received paramater well. but Controller insert only created_at, updated_at date column.

Just remove this line

attr_accessor :email, :pwd, :usertype

from your User class.

The setter and getter methods generated by attr_accessor override the getter and setter methods that are created by Rails automatically.
