Bonjour,

Lorsque je veux lancer mon serveur :

python manage.py runserver

J'obtiens l'erreur suivante :

ERRORS:                                                                       forums.Topic.topic_author: (fields.E304) Reverse accessor for 'Topic.topic_author' clashes with reverse accessor for 'Topic.topic_last_reply_by'.

Voici le code de mon app "forums" :

from django.db import models
from django.contrib.auth.models import User

# Create your models here.
class Forum(models.Model):
    forum_name = models.CharField(max_length=20, unique=True)
    forum_description = models.CharField(max_length=200)

class Topic(models.Model):
    topic_name = models.CharField(max_length=20)
    topic_description = models.CharField(max_length=200)
    topic_author = models.ForeignKey(User, related_name="topics", on_delete=models.CASCADE)
    topic_creation_date = models.DateTimeField(auto_now_add=True)
    topic_replies_number = models.IntegerField(default=0)
    topic_views_number = models.IntegerField(default=0)
    topic_last_reply_by = models.ForeignKey(User, related_name="topics", on_delete=models.CASCADE)

class Post(models.Model):
    topics = models.ForeignKey(Topic, related_name="posts", on_delete=models.CASCADE)
    post_author = models.ForeignKey(User, related_name="posts", on_delete=models.CASCADE)
    post_created_date = models.DateTimeField(auto_now_add=True)
    post_updated_date = models.DateTimeField(null=True)
    post_content = models.CharField(max_length=10000)

Merci d'avance pour votre aide
