如何在DJango管理界面中显示ForeignKey反向查找列表？ [英] How to I show a list of ForeignKey reverse lookups in the DJango admin interface?

问题描述

我有几个模型：

class Customer(models.Model):
    customer_name = models.CharField(max_length=200)

    def __unicode__(self):
        return self.customer_name

    class Meta:
        ordering = ('customer_name',)

class Unit(models.Model):
    unit_number = models.IntegerField()
    rentable = models.BooleanField()
    owner = models.ForeignKey(Customer, related_name='units', blank=True, null=True)

    def __unicode__(self):
        return str(self.unit_number)

    class Meta:
        ordering = ('unit_number',)

我的管理界面正常工作我添加了一个单位（我可以选择哪个客户分配给它），但是当我在DJango管理界面中创建/编辑客户时，它不列出任何可供选择的单位。如何在该部分中启用查找以匹配创建/编辑客户区域中的查找？

I have the admin interface working fine when I'm adding a unit (I can select which customer to assign it to) but when I go to create/edit a customer in the DJango admin interface, it doesn't list any units to choose from. How can I enable the lookup in that section to match the one in the create/edit customer area?

推荐答案

默认情况下， ModelAdmin只能让你管理模型本身，而不是相关模型。为了编辑相关的Unit模型，您需要定义一个InlineModelAdmin，例如admin.TabularInline，并将其附加到您的CustomerAdmin。

By default, a ModelAdmin will only let you manage the model "itself", not related models. In order to edit the related Unit model, you need to define an "InlineModelAdmin" - such as admin.TabularInline - and attach it to your CustomerAdmin.

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-对象

例如，在您的admin.py中：

For example, in your admin.py:

from django.contrib import admin
from models import Customer, Unit

class UnitInline(admin.TabularInline):
    model = Unit

class CustomerAdmin(admin.ModelAdmin):
    inlines = [
        UnitInline,
    ]
admin.site.register(Customer, CustomerAdmin)
