Recibí el siguiente error después de agregar un nuevo campo de modelo y ejecutar el comando makemigrations:

ImportError: no se puede importar el nombre 'FieldDoesNotExist' de 'django.db.models' (/usr/local/lib/python3.7/site-packages/django/db/models/ init .py)

así es como se ve mi models.py:

 import uuid from django.contrib.auth import get_user_model from django.db import models from django.urls import reverse # Create your models here. class Book(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.CharField(max_length=200) author = models.CharField(max_length=200) price = models.DecimalField(max_digits=6, decimal_places=2) cover = models.ImageField(upload_to='covers/', blank=True) # New Field def __str__(self): return self.title def get_absolute_url(self): return reverse('book_detail', args=[str(self.id)]) class Review(models.Model): book = models.ForeignKey(Book, on_delete=models.CASCADE, related_name='reviews') review = models.CharField(max_length=255) author = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) def __str__(self): return self.review

Este es el estado actual de mis archivos de migraciones, tengo dos. 0001_inicial.py

Este es el rastreo de excepción después de ejecutar el comando makemigration:

Entonces, no sé qué causó exactamente este error y estoy atascado en esta etapa. Cualquier ayuda sería muy apreciada.
