如何在Django管理站点上启用内联ManyToManyField？

Question

假设我有书籍和作者模型.

class Author(models.Model):
    name = CharField(max_length=100)

class Book(models.Model):
    title = CharField(max_length=250)
    authors = ManyToManyField(Author)

我希望每本书都有多个作者,在Django管理网站上,我希望能够一次性从编辑页面中将多个新作者添加到一本书中.我不需要为作者添加书籍.

这可能吗？如果是这样,最好和/或最简单的方法是什么？

Answer 1

做你想做的事情很简单,如果我找到你的话:

您应该在apps目录中创建一个admin.py文件,然后编写以下代码:

from django.contrib import admin
from myapps.models import Author, Book

class BookAdmin(admin.ModelAdmin):
     model= Book
     filter_horizontal = ('authors',) #If you don't specify this, you will get a multiple select widget.

admin.site.register(Author)
admin.site.register(Book, BookAdmin)

Answer 2

试试这个:

class AuthorInline(admin.TabularInline):

    model = Book.authors.through
    verbose_name = u"Author"
    verbose_name_plural = u"Authors"


class BookAdmin(admin.ModelAdmin):

    exclude = ("authors", )
    inlines = (
       AuthorInline,
    )

如果您有许多作者raw_id_fields = ("author", ),AuthorInline则可能需要添加.
