Django的选择2不与Django的管理内联工作

Question

这里是我的模型和管理类：

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

我想实现django-select2，但是当我在 PurchaseOrderAdmin使用内联不显示场在那里我已经实现 django-select2：

但是当我删除内联，它工作正常：

这里是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'}

它通过添加以下行静态/西装为我工作/ JS/suit.js

地址：

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