Question

所以我试图通过在DjangoProject上做“第一个Django应用程序”的事情来加速Django的侧面项目，但是当我第一次尝试设置视图时，我收到了这个奇怪的消息

ImportError at /index
cannot import name views

它说错误发生在第二行的root / polls / admin.py中，似乎抱怨无法导入“视图”。问题是我不想在

中导入视图

admin.py

#admin.py
from django.contrib import admin
from polls.models import Choice
from polls.models import Poll
# admin.site.register(Poll)

class ChoiceInline(admin.TabularInline):
    model = Choice
    extra = 1

class PollAdmin(admin.ModelAdmin):
    fields = ["pub_date", "question"]
    inlines = [ChoiceInline]
    list_display = ("question", "pub_date", "was_published_recently")
    list_filter = ['pub_date']
    sarch_fields = ['question']
    date_heirarchy = 'pub_date'

admin.site.register(Poll, PollAdmin)

# admin.site.register(Choice)

错误消息还表明问题是对Choice模型的导入调用，但也不会调用视图。

#models.py
from django.db import models
import datetime
from django.utils import timezone

# Create your models here.

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date_published')
    def __unicode__(self):
        return self.question
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)
    def __unicode__(self):
        return self.choice_text

关于如何解决此问题的任何想法？

更新

#views.py
from django.http import HttpResponse
# from django.views.generic.base import TemplateView

def index(request):
    return HttpResponse("You found the Poll Index.")

#urls.py
from django.conf.urls.defaults import * #patterns, url
#
from polls import views

urlpatterns = patterns('',
    url(r'^$', views.index, name='index')
)

更新＃2：奇怪的是，如果我注释掉整个admin.py文件，并将from polls import views重新定义为import views，那么它可以工作，但是这样做我已经杀了我的管理部分。有什么想法吗？

Answer 1

您的地址栏中有：

http://localhost:8000/index

但是你的urls.py说：

urlpatterns = patterns('',
    url(r'^$', views.index, name='index')
)

所以，Django实际上是在努力查找：

http://localhost:8000/

这就是为什么找不到第一个网址。

Answer 2

好的，所以我“修复”了这个错误，虽然我不确切知道为什么会这样。

在admin.py中，我从

更改了导入

from django.contrib import admin
from polls.models import Choice
from polls.models import Poll

到

import views
from django.contrib import admin
from models import *

也许它与文件组织有关？无论如何，感谢评论家伙。

有同样的问题：
在 Windows7 上，IDE IntelliJ IDEA
在models.py中当导入如下：

from django.db import models

from django.utils import timezone
import datetime

我收到了错误：

ImportError: cannot import name Poll

当我更改导入（使用IntelliJ Ctrl + Alt + l 中的代码重新格式化）到：

import datetime

from django.db import models

from django.utils import timezone

一切都开始神奇地工作了：）
