Django admin 需要内联模型管理员
有了下面这样的模型，在管理面板创建/编辑作者实例时如何要求至少添加一本书？
#models.py
class Author(models.Model):
name = models.CharField(max_length=100)
class Book(models.Model):
author = models.ForeignKey(Author)
title = models.CharField(max_length=100)
#admin.py
class BookInline(admin.TabularInline):
model = Book
class AuthorAdmin(admin.ModelAdmin):
inlines = [
BookInline,
]
Having a such model below, how can I require atleast one book to be added while creating/editting Author instance at admin panel?
#models.py
class Author(models.Model):
name = models.CharField(max_length=100)
class Book(models.Model):
author = models.ForeignKey(Author)
title = models.CharField(max_length=100)
#admin.py
class BookInline(admin.TabularInline):
model = Book
class AuthorAdmin(admin.ModelAdmin):
inlines = [
BookInline,
]
