1、配置test2.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <li>获取单个数据</li> <li>ID:{{student.id}}---name:{{student.name}}---sex:{{student.sex}}</li> </body> </html>
2、配置student_list。html
<!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> <li>数据过滤</li> {% for student in studentList %} <li>{{student.name}},{{student.age}}</li> {% endfor %} <li>获取单个数据</li> <li>{{student}}</li> </body> </html>
3、配置urls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/$','student_list'), url(r'^test2/$','test2'), )
4、配置views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Student等模块 from blog.models import * def student_list(request): t=loader.get_template("student_list.html") #第1种方法：输出数据库中student表中的数据 #studentList = Student.objects.all() # 等价于 select * from student #第2种方法：根据age字段做排序处理并输出结果 .order_by("age") #studentList = Student.objects.all().order_by("age") #第3种方法：根据age字段做降序处理并输出结果 .order_by("-age") #studentList = Student.objects.all().order_by("-age") # 第4种方法：支持多个字段排序 #studentList = Student.objects.all().order_by("age","name") # 第5种方法：支持过滤 #studentList = Student.objects.filter( age= 16 ) # 第6种方法：过滤大于16的数据 #age__gt=16等价于age > 16，注意age和__gt之间是没有空格的 studentList = Student.objects.filter(age__gte = 16) c = Context({"studentList": studentList}) return HttpResponse(t.render(c)) def test2(request): t=loader.get_template("test2.html") #第7种方法：获取单个数据 student = Student.objects.get(id=1) #第8种方法：修改数据库数据并保存 student.name='xiaodeng' student.age=28 student.intime = '1987-08-22' student.save() #第9种方法：批量更新数据 studentList=Student.objects.filter(age__lt=17).update(name = 'FengMei') #新增语句,刷新多少次就会增加多少条记录 newData=Student(name='python',age=1000,intime='1999-09-09',sex=0) newData.save() #删除数据,二次操作会报错，因为索引7已经删除了，不存在了，再次删除索引7当然会出错。 #student = Student.objects.get(id=7) #student.delete() # 删除所有数据 #Student.objects.all().delete() #student={} student = Student.objects.get(id=1) c = Context({"student": student}) return HttpResponse(t.render(c)) class Person(): def __init__(self,name,age,sex): self.age=age self.sex=sex self.name=name 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): #第二个项目 #return HttpResponse("hello,Django") #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))
