What's wrong? blit function in pygame: 'Rects' object has no attribute?

Question

Python

Explain to the old fool what's wrong. My face is already on fire, I don’t understand what’s wrong?

AttributeError: 'Rects' object has no attribute 'model'

Well, I look and see no reason, because the principles are the same.

well he writes:

hero = pg.Surface((40, 50))
hero.fill('blue')
rect = hero.get_rect()
screen.blit(hero, rect)

and I write:

self.model = pg.Surface((40, 50))
self.model.fill('black')
self.rect = model.get_rect()
screen.blit(self.model, self.rect)

What is the difference that I have an error?

class Rects:
  def __init(self):

    self.screen 			= screen
    self.screen_rect 		= screen.get_rect()
    self.screen_bg_color   	= (123, 104, 238)

    self.model = pg.Surface((40, 50))
    self.model.fill('black')
    self.rect = model.get_rect()
    self.rect.bottom = screen_rect.bottom
    self.rect.centerx = screen_rect.centerx

  def update_screen(self, screen):
    screen.fill((123, 104, 238))
    screen.blit(self.model, self.rect)
    pg.display.update()

def start(): 
  pg.init()
  pg.display.set_caption("отчание")
  fpsClock = pg.time.Clock()
  screen = pg.display.set_mode((screen_width, screen_height))
  rects = Rects()
  
  while True:
    check_events()
    rects.update_screen(screen)
    fpsClock.tick(FPS)

start()

I'm already so desperate that I want to quit everything. You sit, stare for an hour and do not understand why it does not work.
