devise model cannot be saved into database-CodePudding

So I have a devise model User, and I added some fields to it like username, address, and so on. The model looks like this:

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable

  attr_accessor :username, :first_name, :last_name, :address

  def profile(username)
    User.find_by(:username => username)
  end
end

Then I am writing RSpec test for this model. However, when I am adding a new user record into the db, it fails. This piece of code looks like this:

require 'rails_helper'

RSpec.describe User, type: :model do
  before(:all) do
    User.create(email: "[email protected]", address: "nyc", first_name: "aa", last_name: "bb", username: "lol")
    puts User.count
  end

  after(:all) do
    User.destroy_all
  end

  it 'should return correct record when we query by username' do
    user = User.find_by(username: "lol")
    puts user
    expect(user.address).eql? "nyc"
  end
end

But when I run rails spec, the count of the table is zero, so it seems like the create method fails. Also, it raised an error: "undefined method `address' for nil:NilClass".
The reason why I suspect it is caused by devise is that when I commented out the line started by devise in the User model, the rspec works as normal.
So does anyone know the reason? I have searched relevant posts but none of them has my situation. Thank you.

CodePudding user response：

If you wanna create User with Devise, you need to provide password for your user. Something below might work:

User.create(
  email: "[email protected]",
  address: "nyc",
  first_name: "aa",
  last_name: "bb",
  username: "lol",
  password: "something",
  password_confirmation: "something",
  )

Tips: You don't need to declare in attr_accessor. You can remove it. And use the new hash style

# old style
User.find_by(:username => username)

# new style
User.find_by(username: username)
