Getting two errors for password presence in activerecord

Question

I am testing my user input validation in my application and I am getting two errors in regards to my password presence.

This is what I have written for my model.

class User < ActiveRecord::Base
  include Slugifiable
  extend Slugifiable::Find

  has_secure_password
  has_many :posts

  validates :email, uniqueness: true, presence: true
  validates :username, uniqueness: true, presence: true
  validates :password, presence: true

end

Below is my migration table:

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.string :email
      t.string :username
      t.string :password
      t.string :password_digest
    end
  end
end

Each time I run my application with no input it should give me three error messages: "Password can't be blank", "Email can't be blank", "Username can't be blank". Instead I get an extra "Password can't be blank" error. I am using a password_digest variable which is a salted hash of the users password once the data persists in the database.

Answer 1

has_secure_password comes with its own presence validation on the create action. Therefore, validating the presence of password is redundant and is causing you to get two "Password can't be blank" error messages.

Simply remove validates :password, presence: true or add a condition to the validation for a specific controller action/other context...ie

validates :password, presence: true, on: :some_action
