我的views.py是 -

from django.shortcuts import render
from django.db.models import Q
from django.shortcuts import render_to_response
from django.template import Template, Context
from books.models import Book
from books.forms import ContactForm,PublisherForm
from django.core.mail import send_mail
# Create your views here.




def search(request):
    query = request.GET.get('q', '')
    if query:
        qset = (
            Q(title__icontains=query) |
            Q(authors__first_name__icontains=query) |
            Q(authors__last_name__icontains=query)
            )
        results = Book.objects.filter(qset).distinct()
    else:
        results = []
    return render_to_response("search.html", {
        "results": results,
        "query": query
        })



def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            topic = form.clean_data['topic']
            message = form.clean_data['message']
            sender = form.clean_data.get('sender', 'noreply@example.com')
            send_mail(
                'Feedback from your site, topic: %s' % topic,
                message, sender,
                ['administrator@example.com']
            )
            return HttpResponseRedirect('/contact/thanks/')
    else:
        form = ContactForm()
    return render_to_response('contact.html', {'form': form})



def addPublisher(request):
    if request == 'POST':
        form = PublisherForm(request.POST)
        if form.is_valid:
            form.save()
            return HttpResponseRedirect('add_publisher/thanks/')
        else:
            form = PublisherForm()
        return render_to_response('book/addPublisher.html',{'form':form})

我的urls.py有以下代码 -

from django.conf.urls import include, url
from django.contrib import admin
from views import *


urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$',home),
    url(r'^search/$',search),
    url(r'^contact/$',contact),
    url(r'^add/$',addPublisher)
    ]

您的urls.py文件可能与您的views.py不在同一个应用程序（文件夹）中。您收到此错误消息称addPublisher 未定义，因为它实际上不是那里，那里我指的是urls.py所在的应用程序

如果上面的特定views.py位于其他应用中，请将其导入类似

的内容来自[应用名称] .view导入*

无论如何，向我们展示您项目的布局将有助于我们为您提供更直接，更具体的答案！谢谢。
