I want to try to add a ListField increasible on django admin. I discover I can do that with inlines, so I goes to the doc to find this code :
models.py
from django.db import models
class Author(models.Model):
name = models.CharField(max_length=100)
class Book(models.Model):
author = models.ForeignKey(Author, on_delete=models.CASCADE)
title = models.CharField(max_length=100)
admin.py
class BookInline(admin.TabularInline):
model = Book
class AuthorAdmin(admin.ModelAdmin):
inlines = [
BookInline,
]
I simply copy this code to see how it render on Django admin page. But the following error appear :
<class 'users.admin.BookInline'>: (admin.E202) 'users.Book' has no ForeignKey to 'users.Book'.
I don't understand why because Book as a ForeignKey. Am I missing something ?
Thx
