我安装了 django-cities-light 和 django-autocomplete-light。一切都很顺利，直到我试图阻止用户选择布鲁塞尔作为地区，如果他们进入法国作为国家。

我在这里按照教程进行操作：http: //django-autocomplete-light.readthedocs.org/en/v2/dependant.html但我不知何故错过了一个重要的细节。

自动完成应用程序工作正常，但没有限制。由于我不知道类媒体应该是什么，我猜问题可能是这样。此外，文档说它用于加载一些额外的 javascript 代码，并且由于应用程序运行正常，它似乎没有被加载。

这是我的models.py

from django.db import models
from user.models import User
from cities_light.models import City, Country, Region

class Offer(models.Model):
    publisher = models.ForeignKey(User)
    content = models.TextField()
    date = models.DateTimeField(auto_now_add=True, auto_now=False)

    country = models.ForeignKey(Country)
    region = models.ForeignKey(Region)
    city = models.ForeignKey(City)

autocomplete_light_registry.py

import autocomplete_light
from offers.models import Offer
from cities_light.models import Country, Region, City

class CountryAutocomplete(autocomplete_light.AutocompleteModelBase):
    attrs={'placeholder': 'Choisissez votre Pays'}
    search_fields=('search_names', 'alternate_names',)

    def choices_for_request(self):
        q = self.request.GET.get('q', '')
        country_id = self.request.GET.get('country_id', None)

        choices = self.choices.all()
        if q:
            choices = choices.filter(name_ascii__icontains=q)
        if country_id:
            choices = choices.filter(country_id=country_id)

        return self.order_choices(choices)[0:self.limit_choices]

autocomplete_light.register(Country, CountryAutocomplete)

class RegionAutocomplete(autocomplete_light.AutocompleteModelBase):
    attrs={'placeholder': 'region name ..'}
    search_fields=('search_names', 'alternate_names',)

    def choices_for_request(self):
        q = self.request.GET.get('q', '')
        country_id = self.request.GET.get('country_id', None)

        choices = self.choices.all()
        if q:
            choices = choices.filter(name_ascii__icontains=q)
        if country_id:
            choices = choices.filter(country_id=country_id)

        return self.order_choices(choices)[0:self.limit_choices]

autocomplete_light.register(Region, RegionAutocomplete)


class CityAutocomplete(autocomplete_light.AutocompleteModelBase):
    attrs={'placeholder': 'Choisissez votre ville'}
    search_fields=('search_names', 'alternate_names',)

    def choices_for_request(self):
        q = self.request.GET.get('q', '')
        city_id = self.request.GET.get('city_id', None)

        choices = self.choices.all()
        if q:
            choices = choices.filter(name_ascii__icontains=q)
        if city_id:
            choices = choices.filter(country_id=country_id)

        return self.order_choices(choices)[0:self.limit_choices]

autocomplete_light.register(City, CityAutocomplete)

表格.py

from django import forms
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin
from django.utils.translation import ugettext_lazy as _
from django.conf import settings

from offers.models import Offer, LevelChoices, CoursChoices

import autocomplete_light


class SendOfferForm(autocomplete_light.ModelForm):

    class Media:
        js = ('dependant_autocomplete.js',)
    class Meta:
        model = Offer
        autocomplete_fields = ("country", "region", "city")
        fields = ('country', 'region', 'city', 'content')

编辑

我发现如果我删除 autocomplete_light_registry.py 中 attrs 字段之后的所有代码，则没有任何变化。django 无法识别某些内容。我检查了我的 settings.py，但似乎还可以

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
)

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, '/media/')

  1. 将“autocomplete_light.example_apps.dependant_autocomplete”添加到您安装的应用程序中

  2. 通过管理界面访问新添加的应用程序

  3. 检查自动完成过滤器是否正确
  4. 如果是 完成
  5. 如果不是，请将您的计算机连接到 Internet 并重复步骤 2 和 3
