基础

from django.db import models

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

class Book(models.Model):
    author = models.ForeignKey(Author)
    title = models.CharField(max_length=100)

如果想在Author页面上编辑book：

from django.contrib import admin

class BookInline(admin.TabularInline):
    model = Book

class AuthorAdmin(admin.ModelAdmin):
    inlines = [BookInline,]

Django提供了两个InlineModelAdmin的子类:TabularInline和StackedInline，基本功能一样，只是样式不同

多对多

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=128)

class Group(models.Model):
    name = models.CharField(max_length=128)
    members = models.ManyToManyField(Person, through='Membership')

class Membership(models.Model):
    person = models.ForeignKey(Person)
    group = models.ForeignKey(Group)
    date_joined = models.DateField()
    invite_reason = models.CharField(max_length=64)

from django.contrib import admin

class MembershipInline(admin.TabularInline):
    model = Group.members.through

class PersonAdmin(admin.ModelAdmin):
    inlines = [
        MembershipInline,
    ]

class GroupAdmin(admin.ModelAdmin):
    inlines = [
        MembershipInline,
    ]
    exclude = ('members',)

admin.site.register(Person, PersonAdmin)
admin.site.register(Group, GroupAdmin)

注意事项：

1. MembershipInline类指向Group.members.through
2. GroupAdmin 必须排除 members字段.
