astroid.exceptions.AstroidImportError: Failed to import module main.models with error:
No module named main.models.

this is my model

class EngravingPromotionOrder(models.Model):
    engraving_promotion_number = models.ForeignKey('main.EngravingPromotion', blank=True, null=True, related_name='engraving_promotion', on_delete=models.CASCADE)
    order_number = models.OneToOneField('order.Order', blank=True, null=True, on_delete=models.CASCADE)

if i change it to this way,the error will dissappear

from xxx.apps.main.models import EngravingPromotion
class EngravingPromotionOrder(models.Model):
    engraving_promotion_number = models.ForeignKey(EngravingPromotion, blank=True, null=True, related_name='engraving_promotion', on_delete=models.CASCADE)
    order_number = models.OneToOneField('order.Order', blank=True, null=True, on_delete=models.CASCADE)

do we must to use the second way,if not it will raise error
i find a similar issue #2995 also use this way to slove the error
