2、配置C:\djangoweb\helloworld\blog\urls.py文件
# -*- coding: UTF-8 -*-
from django.conf.urls import patterns, include, url
urlpatterns = patterns(‘blog.views‘,
url(r‘^index/$‘, ‘index‘),
url(r‘^time/$‘, ‘time‘),
url(r‘^shengfen/$‘, ‘shengfen‘),
#url(r‘^foo/(\d{4})/$‘, ‘foo‘), #表示接收4个数字,#\w+接收至少一个字母
url(r‘^foo/(\d{4})/(\w+)/$‘,"foo"),
url(r‘^bar/(?P<id>\d{4})/(?P<name>\w+)/$‘,‘bar‘),#强制规定bar(request,id,name)处的参数必须为id和name
url(r‘^student_list/$‘,‘student_list‘),#当浏览器打开此网址时，输出html页面的结果（html页面定义了从数据库抓取数据的代码）
)
3、配置views.PY文件
# Create your views here.
#coding:utf-8
from django.http import HttpResponse
import datetime
#导入templates文件所需导入库
from django.template import loader,Context
#引入models模块中的Student等类
from blog.models import *
def student_list(request):
t=loader.get_template("student_list.html")
studentList = Student.objects.all() # 等价于 select * from student
c=Context({"studentList":studentList})
return HttpResponse(t.render(c))
class Person():
def __init__(self,name,age,sex):
self.name=name
self.age=age
self.sex=sex
def myMethod(self):
return "get it"
def time(request):
t = loader.get_template("time.html")
myId = request.GET.get("id")
myName = request.GET.get("name")#获取传递的name的value值
user = {"today": datetime.datetime.now(),"id":myId,"name":myName}
c = Context(user)
return HttpResponse(t.render(c))
def foo(request,myID,myName):
t = loader.get_template("foo.html")
user = {"today": datetime.datetime.now(),"id":myID,"name":myName}
c = Context(user)
return HttpResponse(t.render(c))
def bar(request,id,name):
t = loader.get_template("bar.html")
user = {"today": datetime.datetime.now(),"id":id,"name":name}
c = Context(user)
return HttpResponse(t.render(c))
def shengfen(request):
t = loader.get_template("shengfen.html")
user = {"shengfen":"湖北省恩施市"}
c = Context(user)
return HttpResponse(t.render(c))
def index(request):
#加载器，加载模板
t=loader.get_template("index.html")
# django之创建第4-1个项目-Dict形式
user = {"name": "xiaodeng", "sex": "male", "age": 28,"today":datetime.datetime.now()}
c = Context({"test": user}) # 在这里test位变量，user为变量的值
return HttpResponse(t.render(c))
4、创建student_list.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<li>遍历数据库student中的数据</li>
{% for student in studentList %}
<li>{{student}}</li> <!--Student objec-->
{% endfor %}
<br>
{% for student in studentList %}
<li>{{student.name}},{{student.age}}</li>
{% endfor %}
</body>
</html>
5、启动服务器，manage.py runserver
6、打开 http://127.0.0.1:8000/blog/student_list/
