Question

所以我是一名学生，我正在尝试使用Django建立一个小商店，所以当我在我的笔记本电脑上运行该项目时，它按预期工作，但当我将其上传到服务器时，我收到此错误

无法导入名称＆＃39; CustomerOrderModel＆＃39;

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 Value: cannot import name 'CustomerOrderModel'

Answer 1

来自模型导入CustomerOrderModel

Answer 2

试试这个：

from HomePage.models import CustomerOrderModel

Answer 3

我可以看到，这是由于你的urls.py中的循环导入你在做 from . import views 你应该这样做 from .vies import XyzView, AbcView

这是因为您要导入在views.py中完成的所有导入。希望你明白了。
