django可选不工作自动完成

我想用django

model.py：

    class Country(models.Model):
    name      = models.CharField(verbose_name='Страна', max_length=128, blank=True) 

    def __str__(self):
        return self.name

class Region(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True) 

    def __str__(self):
        return self.name   

class City(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    region    = models.ForeignKey(Region, verbose_name='Регион')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True)

    def __str__(self):
        return self.name 

from subscribers.models import City
from selectable.base import ModelLookup
from selectable.registry import registry


class CityLookup(ModelLookup):
    model = City
    search_fields = ('name__icontains', )

registry.register(CityLookup)

import selectable.forms as selectable
from subscribers.models import City
from partners.lookup import CityLookup



class ShowSomeForm(forms.Form):
    autocomplete = forms.CharField(
        label='Type the name of a fruit (AutoCompleteWidget)',
        widget=selectable.AutoCompleteWidget(CityLookup),

    )

Lookup.py：

    class Country(models.Model):
    name      = models.CharField(verbose_name='Страна', max_length=128, blank=True) 

    def __str__(self):
        return self.name

class Region(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True) 

    def __str__(self):
        return self.name   

class City(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    region    = models.ForeignKey(Region, verbose_name='Регион')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True)

    def __str__(self):
        return self.name 

from subscribers.models import City
from selectable.base import ModelLookup
from selectable.registry import registry


class CityLookup(ModelLookup):
    model = City
    search_fields = ('name__icontains', )

registry.register(CityLookup)

import selectable.forms as selectable
from subscribers.models import City
from partners.lookup import CityLookup



class ShowSomeForm(forms.Form):
    autocomplete = forms.CharField(
        label='Type the name of a fruit (AutoCompleteWidget)',
        widget=selectable.AutoCompleteWidget(CityLookup),

    )

forms.py：

    class Country(models.Model):
    name      = models.CharField(verbose_name='Страна', max_length=128, blank=True) 

    def __str__(self):
        return self.name

class Region(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True) 

    def __str__(self):
        return self.name   

class City(models.Model):
    country   = models.ForeignKey(Country, verbose_name='Город')
    region    = models.ForeignKey(Region, verbose_name='Регион')
    name      = models.CharField(verbose_name='Город', max_length=128, blank=True)

    def __str__(self):
        return self.name 

from subscribers.models import City
from selectable.base import ModelLookup
from selectable.registry import registry


class CityLookup(ModelLookup):
    model = City
    search_fields = ('name__icontains', )

    autocomplete = forms.CharField(
        label='Type the name of a fruit (AutoCompleteWidget)',
        widget=selectable.AutoCompleteWidget(CityLookup),

    )

view.py

...     
        form = ShowSomeForm()      
        return render(request, 'personal_accout_partners.html', {'formPart': formPartners, 'formMes': formMessages, 'form': form}) 

个人账户合作伙伴.html

{{form}}

对此问题我能做些什么？

请详细说明什么不起作用，调试控制台中是否出现异常或javascript错误（如果是，请将其包含在问题中），Tutudaju，在字段中写入时，项中的表单不会自动完成（可能是我不明白一些重要的事情。如果你有简单的例子，请写下来）
