Django的選擇2不與Django的管理內聯工作

Question

這裏是我的模型和管理類：

---------------------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/') 

我想實現django-select2，但是當我在 PurchaseOrderAdmin使用內聯不顯示場在那裏我已經實現 django-select2：

但是當我刪除內聯，它工作正常：

這裏是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'}

它通過添加以下行靜態/西裝爲我工作/ JS/suit.js

地址：

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