所以我尝试为django 1.11.4实现django-smart-selects 1.5.9，但不知何故，链接键无法正常工作。

class Province(models.Model):
    name = models.CharField(
        max_length=30
    )
    class Meta:
        verbose_name = _("province")
        verbose_name_plural = _("provinces")

    def __str__(self):
        return self.name

class District(models.Model):
    province = models.ForeignKey(
        Province, 
        on_delete=models.CASCADE
    )
    name = models.CharField(
        max_length=50
    )
    class Meta:
        verbose_name = _("district")
        verbose_name_plural = _("districts")

    def __str__(self):
        return self.name

class City(models.Model):
    district  = models.ForeignKey(
        District, 
        on_delete=models.CASCADE
    )
    name = models.CharField(
        max_length=50
    )
    class Meta:
        verbose_name = _("city")
        verbose_name_plural = _("cities")

    def __str__(self):
        return self.name

class Ward(models.Model):
    city = models.ForeignKey(
        City,
        on_delete=models.CASCADE
    )
    name = models.CharField(
        max_length=2
    )
    class Meta:
        verbose_name = _("ward")
        verbose_name_plural = _("wards")

    def __str__(self):
        return self.name
class School(models.Model):
   # other fields .....
    province = models.ForeignKey(
        Province, 
        on_delete=models.SET_NULL, 
        blank=True,
        null = True,
        verbose_name = _("province")
    )
    district = ChainedForeignKey(
        District,
        chained_field="province",
        chained_model_field="province",
        show_all=False,
    )
    city = ChainedForeignKey(
        City,
        chained_field="district",
        chained_model_field="district",
        show_all=False,
    )
    ward = ChainedForeignKey(
        Ward,
        chained_field="city",
        chained_model_field="city",
        show_all=False,
    )

urls.py

url(r'^admin/', admin.site.urls),
    url(r'^admin/', include('smart_selects.urls')),

admin.py

@admin.register(School)
class SchoolAdmin(admin.ModelAdmin):
    inlines = [ServerInline, ServerUpdateInline]
    list_display = ['school_name', 'school_type','phone', 
    'province', 'district', 'city', 'ward',
]
    search_fields = ('school_name','district__name')
    list_filter = ('school_type', 'district')

在这里尝试了从django-smart-selects链接下拉实现模型和管理员是在一个单独的应用程序称为学校和我提供的URL是在基地django目录的url.py
