python - 属性错误 : 'function' object has no attribute 'views'

Question

你好，我正在学习用于 Web 应用程序的 Django 框架

我正在尝试根据教程构建基本博客

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。

有我的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views.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]
    })

有我的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 应该是一个 list(方括号 [...] 而不是花括号 {...} 正如你所拥有的。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'),
]
