私はpythonとweb-devを学びたいと思いますし、機能的なWebアプリケーションを作ろうとしています。今、私はdjango-autocomplete-lightに問題があります。Djangoのdjango-autocomplete-lightが結果を表示しない
私は自分のdjangoアプリケーションにオートコンプリートを使用しようとしています。私はチュートリアルに従いましたが、検索しようとするとThe results could not be loaded. しかし、結果はドロップダウンリストに表示されます。
私は、ユーザーが新しいinvoceを追加することができ、フォームを持っている
マイモデル：
class Supplier(models.Model):
supp_name = models.CharField(max_length=255)
mat_number = models.CharField(max_length=255)
organ = models.CharField(max_length=255, null=True, blank=True)
street = models.CharField(max_length=255, null=True, blank=True)
email = models.CharField(max_length=255, null=True, blank=True)
def __str__(self):
return self.supp_name.encode("utf-8")
def get_absolute_url(self):
return reverse('supplier-detail', args=[str(self.id)])
def __unicode__(self):
return '%s' % (self.supp_name,)
class Invoice(models.Model):
organization = models.ForeignKey(Group, help_text="organization")
input_peo = models.CharField(max_length=150)
date = models.DateTimeField(auto_now_add=True)
supplier = models.ForeignKey(Supplier, on_delete=models.SET_NULL, null=True, related_name='name')
invoice_number = models.CharField(max_length=100, null=True, blank=True, help_text='Številka preračuna')
price = models.FloatField(null=True, blank=True, help_text='Cena brez DDV')
sum_me = models.IntegerField(null=True, blank=True, help_text='Kolicina')
def __str__(self):
return self.organization.name.encode("utf-8")
def get_absolute_url(self):
return reverse('invoice-detail', args=[str(self.id)])
マイビュー：
class AddInvoice(LoginRequiredMixin, generic.View):
login_url = '/accounts/login/'
redirect_field_name = 'redirect_to'
form_class = InvoiceCreate
template_name = 'invoce/invoce_form.html'
def get(self, request):
form = self.form_class(None)
return render(request, self.template_name, {'form': form})
def post(self, request):
form = self.form_class(request.POST)
if form.is_valid():
invoice = form.save(commit=False)
invoice.organization = request.user.groups.first()
invoice.input_peo = self.request.user.get_full_name()
invoice.supplier = form.cleaned_data['supplier']
invoice.invoice_number = form.cleaned_data['invoice_number']
invoice.price = form.cleaned_data['price']
invoice.sum_me = form.cleaned_data['sum_me']
invoice.save()
return HttpResponseRedirect('/')
return render(request, self.template_name, {'form': form})

class SupplierAutoComplete(autocomplete.Select2QuerySetView):
def get_queryset(self):
qs = Supplier.objects.all()
if self.q:
qs = qs.filter(name__istartswith=self.q)
return qs
のURL：
urlpatterns += [
url(
r'^autocomplete/$',
views.SupplierAutoComplete.as_view(model=Supplier),
name='supplier-autocomplete',
),
]
私はちょうどブラウザでオートコンプリート（/オートコンプリート/）を検索する場合、これは何をである私取得： 
私forms.py：
class InvoiceCreate(forms.ModelForm):
class Meta:
model = Invoice
fields = [
'supplier',
'invoice_number',
'price',
'sum_me',
]
widgets = {
'supplier': autocomplete.ModelSelect2(url='supplier-autocomplete')
}
、最終的には、フォームのための私のテンプレート：
{% extends "base_generic.html" %}
{% block content %}
<div class="jumbotron">
<div class="row" style="margin-top:60px">
<form action="" method="post">
{% csrf_token %}
<!-- Left Inputs -->
<div class="col-xs-6 wow animated slideInLeft" data-wow-delay=".5s">
<!-- Supplier -->
{{ form.non_field_errors }}
<div class="fieldWrapper">
{{ form.supplier.errors }}
<label>Supplier:</label>
<div class="container">
{{ form.supplier }}
</div>
</div>
<!-- invoice_number -->
{{ form.non_field_errors }}
<div class="fieldWrapper">
{{ form.invoice_number.errors }}
<input type="text" name="invoice_number" id="id_invoice_number" placeholder="Invoice Number" class="form"/>
</div>
<!-- price -->
{{ form.non_field_errors }}
<div class="fieldWrapper">
{{ form.price.errors }}
<input type="text" name="price" id="id_price" placeholder="Price" class="form"/>
</div>
<!-- sum_me -->
{{ form.non_field_errors }}
<div class="fieldWrapper">
{{ form.sum_me.errors }}
<input type="number" name="sum_me" id="id_sum_me" placeholder="Sum" class="form"/>
</div>
</div><!-- End Left Inputs -->
<!-- Bottom Submit -->
<div class="relative fullwidth col-xs-12">
<!-- Send Button -->
<button type="submit" class="form-btn semibold">Add</button>
</div><!-- End Bottom Submit -->
<!-- Clear -->
<div class="clear"></div>
</form>
</div>
</div>
{{ form.media }}
{% endblock %}
