对不起,我已经有了专栏"transdate",为什么它说不存在？

我正在使用"Lightweight Django"这本书学习Django.我正在使用Django 1.8.但是,我无法运行此代码.这是错误消息:

每一个,我都要改变一些代码从python 3.*到2.7 ,,,但是,我只是不知道data = urllib.parse.urlencode(values)python 2.7中的代码是什么

python3.*

import urllib.parse
import urllib.request


def sendsms(phonenumber,textcontent):
    url = 'http://urls?'
    values = {'username' : 'hello',
              'password' : 'world',
              'dstaddr' : phonenumber ,
              'smbody': textcontent
               }

    data = urllib.parse.urlencode(values)
    data = data.encode('Big5') 
    req = urllib.request.Request(url, data)
    with urllib.request.urlopen(req) as response:
       the_page = response.read()

python 2.7

from urlparse import urlparse
from urllib2 import urlopen
from urllib import urlencode

def sendsms(phonenumber,textcontent):
    url = 'http://urls?'
    values = {'username' : 'hello',

我正在尝试使用Django 1.8构建我的博客但是我不知道如何订购博客.看图像

我想在底部显示'最早',在顶部显示'最新'.这是我的

的index.html

Homepage - {{ block.super }}

{% block content %}
<center>
{% for blog in blogs %}
<h2><a href="{% url 'blog_detail' slug=blog.slug %}">
{{ blog.name }}
</a></h2>
<p>{{ blog.description }}</p>

models.py

# -*- coding: utf-8 -*-

每个人：我正在尝试使用 django 1.8，mysql db 练习将 Django 与旧数据库集成，但没有成功，谁能告诉我发生了什么？非常感谢！我的 旧数据库

模型.py

# -*- coding: utf-8 -*-
from django.db import models
from django.utils import timezone


class blog(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()
    slug = models.SlugField(unique=True)
    date_time = models.DateTimeField(auto_now_add = True)

    def __unicode__(self):
        return self.name



def get_image_path(instance, filename):
    return '/'.join(['blog_images', instance.bupimg.slug, filename])

class Upload(models.Model):
    bupimg = models.ForeignKey(blog, related_name="uploads")
    image = models.ImageField(upload_to=get_image_path)

我只是按照这里的文档

在我输入命令后

为什么我的 pidapp/models.py 显示的与旧数据库的 models.py 非常不同

pidapp/models.py

我正在尝试从数据库中搜索并列出两个日期之间的内容，但不知道该怎么做？这

模型.py

...
class ProductsTbl(models.Model):
    created = models.DateTimeField(editable=False)
...

视图.py

def search(request):
    error = False
    if 'q1' and 'q2'in request.GET:
        q = request.GET['q1','q2']
        if not q:
            error = True
        else:
            books = ProductsTbl.objects.filter(created__range=q)
            return render(request, 'search_results.html',
                {'books': books, 'query': q})
    return render(request, 'search_form.html', {'error': error})

我在这里查找了stackoverflow但不明白该怎么做

我应该在 models.py 中再添加一个 DateTimeField 来帮助搜索吗？

实际上我可以在 python manage.py shell 中做到这一点，但我怎样才能让它在网络上工作？
