Джанго-Выбор2 не работает с инлайн в Джанго-администраторе

Question

Вот мои модели и администратор классы:

---------------------Models----------------------- 
from django.contrib.auth.models import User 

class PurchaseOrder(models.Model): 
    buyer = models.ForeignKey(User) 
    is_debit = models.BooleanField(default = False) 
    delivery_address = models.ForeignKey('useraccounts.Address') 
    organisation = models.ForeignKey('useraccounts.AdminOrganisations') 
    date_time = models.DateTimeField(auto_now_add=True) 
    total_discount = models.IntegerField() 
    tds = models.IntegerField() 
    mode_of_payment = models.ForeignKey(ModeOfPayment) 
    is_active = models.BooleanField(default = True) 
    class Meta: 
     verbose_name_plural = "Purchase Orders" 

    def __unicode__(self): 
     return '%s' % (self.id) 

----------------------------------Admin---------------------------------------- 
""" 
This class is used to add, edit or delete the details of item purchased 
""" 
class PurchasedItemInline(admin.StackedInline): 
    form = ItemSelectForm 
    model = PurchasedItem 
    fields = ['parent_category', 'sub_category', 'item', 'qty', ] 
    extra = 10 

class BuyerChoices(AutoModelSelect2Field): 
    queryset = User.objects.all() 
    search_fields = ['username__icontains', ] 

class BuyerForm(ModelForm): 
    user_verbose_name = 'Buyer' 
    buyer = BuyerChoices(
     label='Buyer', 
     widget=AutoHeavySelect2Widget(
      select2_options={ 
      'width': '220px', 
      'placeholder': 'Lookup %s ...' % user_verbose_name 
      } 
     ) 
    ) 

    class Meta: 
     model = PurchaseOrder 
     fields = '__all__' 

""" 
This class is used to add, edit or delete the details of items 
purchased but buyer has not confirmed the items purchased, this class 
inherits the fields of PurchaseOrder derscribing the delivery address of 
buyer , is_debit , total discount , tds and mode of payment 
""" 
class PurchaseOrderAdmin(admin.ModelAdmin): 
    form = BuyerForm 
    #list_display = ['id','buyer','delivery_address','date_time','is_active'] 
    inlines = [PurchasedItemInline] 
    # model = PurchaseOrder 
    #actions = [mark_active, mark_inactive] 
    #list_filter = ['date_time'] 
    #search_fields = ['id'] 
    list_per_page = 20 
    def response_add(self, request, obj, post_url_continue=None): 
     request.session['old_post'] = request.POST 
     request.session['purchase_order_id'] = obj.id 
     return HttpResponseRedirect('/suspense/add_distance/') 

Я пытаюсь реализовать django-select2, но когда я использую Внутристрочные в PurchaseOrderAdmin он не показывает поле, где я реализовал django-select2:

Но когда я удалить Внутристрочные, он отлично работает:

Вот ItemSelectForm

class ItemSelectForm(forms.ModelForm): 
    class Media: 
     js = (
      'http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js', 
      'js/ajax.js', 
     ) 

    try: 
     parent_category = forms.ModelChoiceField(queryset=Category.objects.\ 
      filter(parent__parent__isnull=True).filter(parent__isnull=False)) 

     sub_category_id = Category.objects.values_list('id',flat=True) 
     sub_category_name = Category.objects.values_list('name',flat=True) 
     sub_category_choices = [('', '--------')] + [(id, name) for id, name in 
     itertools.izip(sub_category_id, sub_category_name)] 
     sub_category = forms.ChoiceField(sub_category_choices) 
    except: 
     pass 

    item = forms.ModelChoiceField(queryset = Product.objects.all()) 

    def __init__(self, *args, **kwargs): 
     super(ItemSelectForm, self).__init__(*args, **kwargs) 
     self.fields['parent_category'].widget.attrs={'class': 'parent_category'} 
     self.fields['sub_category'].widget.attrs={'class': 'sub_category'} 
     self.fields['item'].widget.attrs={'class': 'item'} 

Answer 1

Он работал для меня, добавив следующую строку в статическом/костюм/JS/suit.js

Add:

(function ($) { 
    Suit.after_inline.register('init_select2', function(inline_prefix, row){ 
     $(row).find('select').select2(); 
    });
