Django：无法导入名称 'model'

Question

所以我是一名学生，我正在尝试使用 Django 建立一个小商店，所以当我运行我的笔记本电脑上的项目按预期工作但是当我将它上传到服务器时我得到了这个错误

cannot import name 'CustomerOrderModel'

views.py

from django.shortcuts import render, get_object_or_404
from django.views import generic
from HomePage.models import Product
from HomePage.forms import Customer
from django.contrib import messages
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

#other functions

def customer_order_view(request, pk):
   product = get_object_or_404(Product, id=pk)
   form = Customer(request.POST or None)
   if form.is_valid():
      instance = form.save(commit=False)
      instance.customer_product_name = product
      instance.save()
      messages.success(request, "Success \n we will contact you soon")
      context = {'form': form, 'product': product}
   return render(request, 'HomePage/customerDetail.html', context)

forms.py

from django import forms
from HomePage.models import CustomerOrderModel  #the error in this line 

class Customer(forms.ModelForm):
  class Meta:   
    model = CustomerOrderModel   
    fields = [# some fields]

url.py

from django.conf.urls import url
from django.conf import settings
from django.conf.urls.static import static
from HomePage.views import index_view, GiftView, FlowerView, BalloonView, 
detail_view, customer_order_view

app__name = 'HomePage'

urlpatterns = [
              url(r'^$', index_view, name='index'),
              url(r'^gift/$', GiftView.as_view(), name='gift'),
              url(r'^flower/$', FlowerView.as_view(), name='flower'),
              url(r'^balloon/$', BalloonView.as_view(), name='balloon'),
              url(r'^(?P<pk>[0-9]+)/$', detail_view, name='detail'),
              url(r'^(?P<pk>[0-9]+)/order/$', customer_order_view, 
                  name='product_form'),
                  ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Exception Type: ImportError at /8/order/
Exception Value: cannot import name 'CustomerOrderModel'

Answer 1

从模型导入 CustomerOrderModel

Answer 2

试试这个：

from HomePage.models import CustomerOrderModel

Answer 3

我明白了，这是由于您 urls.py 中的循环导入所致你在做 from . import views 你应该这样做 from .views import XyzView, AbcView

这是因为您还导入了在 views.py 中完成的所有导入。希望你明白了。
