django-select2在django-admin中無法與內聯一起使用

Question

這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/')

我正在嘗試實現django-select2 ，但是當我在PurchaseOrderAdmin使用內聯時，它沒有顯示實現django-select2的字段：

但是當我刪除內聯時，它可以正常工作：

這是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'}

它通過在static / suit / js / suit.js中添加以下行為我工作

加：

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