AttributeError：“函数”对象没有属性“视图”

Question

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

Answer 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'),
]
