Hi,
I have the following models:
class UserPost(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL,
on_delete=models.CASCADE)
post = models.ForeignKey(Post, on_delete=models.CASCADE)
created = models.DateTimeField(auto_now_add=True)
class User(AbstractUser):
MALE = 'M'
FEMALE = 'F'
GENDER_CHOICES = (
(MALE, 'Male'),
(FEMALE, 'Female')
)
posts = models.ManyToManyField(Post, through='UserPost')
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
class Post(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL,
on_delete=models.CASCADE)
title = models.CharField(max_length=100)
content = models.TextField()
status = models.CharField(max_length=100)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
When I run python manage.py makemigrations, it raises the following error:
users.User.posts: (fields.E303) Reverse query name for 'User.posts' clashes
with field name 'Post.user'.
HINT: Rename field 'Post.user', or add/change a related_name
argument to the definition for field 'User.posts'.
There is a many-to-many relationship between User and Post models. Each
user can like many posts and each post can be liked by many users.
There is also a many-to-one relationship between User and Post models. Each
user can write many posts and each post can be written by only one user.
Shouldn't reverse query name for 'User.posts' be user_set by default. If
so, why is this name clashing with field name 'Post.user'? Can someone
explain the meaning of this error? Thanks.
