Question

我有2个django模型

class Location
  address = models.CharField(max_length=100)
  city = models.CharField(max_length=20)

class Client
  location = models.ForeignKey(Location)
  name = models.CharField(max_length=100)

我有以下admin.py

class ClientAdmin(admin.ModelAdmin):
fieldsets = [
    ('Client Details', {'fields': ['name']}),
    ('Location Details', {'fields': ['location']}),
]


admin.site.register(Client, ClientAdmin)

当我尝试添加客户端时，我希望有一个可编辑的“位置”字段，即地址和城市文本字段。 django默认给出一个列表..如何从foregin表中获取字段？

我能做到这一点吗？我不希望在管理员中注册位置表。

感谢

您可以为该位置放置一个内联表，并使用方法queryset来处理字段值。所以，这是解决方案的意思：

class LocationInline(admin.StackedInline):
    model = Location

    def queryset(self, request):
        query = ... #your custom query here
        qs = super(LocationInline, self).queryset(request).filter(query)
        return qs


class ClientAdmin(admin.ModelAdmin):
    inlines = [LocationInline]
    fieldsets = [
        ('Client Details', {'fields': ['name']}),
    ]

修改在django 1.1中还有另一种方法。

class ClientAdmin(admin.ModelAdmin): fieldsets = [ ('Client Details', {'fields': ['name']}), ('Location Details', {'fields': ['location']}), ] def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name = "location": locations = Location.objects.filter( ... ) #your query kwargs["queryset"] = Location.objects.filter(query) return super(ClientAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

这是一个老问题，但回答这个问题也可以帮助很多其他人。所以，我希望它有所帮助！ ;）
