【问题描述】：

你好，我正在学习用于 Web 应用程序的 Django 框架

我正在尝试从教程构建基本博客

我被错误困住了：

AttributeError is telling me that  'function' object has no attribute 'views'.

我不知道我的文件哪里有问题，所以我将在此处包含我的文件的一些代码。

这是我的 urls.py

from django.conf.urls import url
from django.contrib import admin
import WarblerTest


urlpatterns = 
    url(r'^admin/', admin.site.urls),
    (r'^$', WarblerTest.blog.views.index),
    url(
        r'^blog/view/(?P<slug>[^\.]+).html',
        WarblerTest.blog.views.view_post,
        name='view_blog_post'),
    url(
        r'^blog/category/(?P<slug>[^\.]+).html',
        WarblerTest.blog.views.view_category,
        name='view_blog_category'),

有我的意见.py

from django.shortcuts import render
from blog.models import Blog, Category
from django.shortcuts import render_to_response, get_object_or_404


def index(request):
    return render_to_response('index.html', 
        'categories': Category.objects.all(),
        'posts': Blog.objects.all()[:5]
    )


def view_post(request, slug):
    return render_to_response('view_post.html', 
        'post': get_object_or_404(Blog, slug=slug)
    )


def view_category(request, slug):
    category = get_object_or_404(Category, slug=slug)
    return render_to_response('view_category.html', 
        'category': category,
        'posts': Blog.objects.filter(category=category)[:5]
    )

这是我的models.py

from django.db import models
from django.db.models import permalink

# Create your models here.

class Blog(models.Model):
    title = models.CharField(max_length = 100,unique = True)
    slug = models.CharField(max_length = 100,unique = True)
    body = models.TextField()
    posted = models.DateField(db_index = True,auto_now_add = True)

    def __unicode__(self):
        return '%s' % self.title

    @permalink
    def get_absolute_url(self):
        return ('view-blog-post',None, 'slug' : self.slug)

class Category(models.Model):
    title = models.CharField(max_length = 100,db_index = True)
    slug = models.SlugField(max_length = 100,db_index = True)

    def __unicode__(self):
        return '%s' % self.title

    @permalink
    def get_absolute_url(self):
        return ('view_blog_category', None,  'slug': self.slug )

还有我的回溯错误

【问题讨论】：

可以分享一下堆栈错误吗

我认为这是 urls.py 的问题，通常我直接通过from . import views 导入视图，然后调用views.view_post

是的，里奇是对的。在 url 中删除 views 之前的 WarblerTest.blog.，并更新您的导入。

请在您的问题中包含完整的回溯，这样我们就无需猜测是哪一行导致了问题。您的 urlpatterns 应该是一个列表，urlpatterns = [...]，而不是一组 urlpatterns = ...。看起来您的urls.py 是您的主要urls.py，而不是您的blog/urls.py。在这种情况下，您需要使用from blog import views，而不是@Richy 建议的from . import views。

更新了我的帖子，您现在可以在我的问题中查看回溯。

【参考方案1】：

在您的主项目 urls.py 中，删除 import WarblerTest 导入并将其替换为 from blogs import views。

然后更新您的 url 模式以使用您导入的 views 模块。请注意，urlpatterns 应该是 list（方括号 [...] 而不是花括号 ...，因为你有。每个项目都应该是 url(...) 而不是元组 (...) 以避免在 Django 1.10+ 中出现问题。

from blogs import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', views.index),
    url(r'^blog/view/(?P<slug>[^\.]+).html', views.view_post, name='view_blog_post'),
    url(r'^blog/category/(?P<slug>[^\.]+).html', views.view_category, name='view_blog_category'),
]
