Django的表'模块'对象没有属性'索引'

Question

我正在尝试使用django表2教程（ Link ），但我一直卡在此错误中。

编辑：当我尝试访问127.0.0.1:8000/tables/时会发生这种情况

我在本教程的这一部分受困：“在URL中查看视图，并加载页面，您应该看到：”它不显示此表，而是显示下面显示的错误。

我尝试了其他问题中列出的解决方案，但没有帮助。 有人能帮助我吗？

这是代码： https : //github.com/karbfg10k/temp-work/tree/master/IMedMonitor/IMed

这是错误

如Joel所述取消对index方法的注释，然后像在people方法中所做的那样呈现html页面，并传递表数据。

https://docs.djangoproject.com/zh-CN/1.9/intro/tutorial03/

在页面下3/4处进行一下修改（以适合您的示例）：

def index(request):
    table_object = ......
    template = loader.get_template('correct_page_here')
    context = {
        'table_obj': table_object,
}
    return HttpResponse(template.render(context, request))

在相应的html页面中添加适当的标记以呈现表

https://django-tables2.readthedocs.org/en/latest/pages/template-tags.html

我将您的模型文件更改为：

from __future__ import unicode_literals

from django.db import models

data = [
    {"name": "Me!"},
    {"name": "Myself!"},
]

# Create your models here.
class Person(models.Model):
    name = models.CharField(verbose_name="full name", max_length = 20)

更改模型文件后，请确保您运行

python manage.py makemigrations && python manage.py migrate

您的table / urls.py文件可以：

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^people/$', views.people, name='people'),
]

您的views.py文件可以：

from django.shortcuts import render
from django.http import HttpResponse
from models import Person 


def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")


def people(request):
    return render(request, "people.html", {"people": Person.objects.all()})
    table = Person(data)

IMed / IMed / settings.py中已安装的应用程序为：

# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_tables2',
    'IMed',
    'tables',
]

现在，如果您运行服务器并转到此处：

http://127.0.0.1:8000/tables/people/

人员视图将起作用，您可以在索引中复制与人员相同的过程。
