Python中django框架两个使用模板实例

今天编程学习网为大家讲解Python中django框架两个使用模板实例，有需要的小伙伴可以参考一下：

本文实例讲述了django框架使用模板。分享给大家供大家参考，具体如下：

models.py：

from django.db import models
# Create your models here.
class Book(models.Model):
  title=models.CharField(max_length=32,unique=True)
  price=models.DecimalField(max_digits=8,decimal_places=2,null=True)
  pub_date=models.DateField()
  publish=models.CharField(max_length=32)
  is_pub=models.BooleanField(default=True)
  authors=models.ManyToManyField(to="Author")
class AuthorDetail(models.Model):
  gf=models.CharField(max_length=32)
  tel=models.CharField(max_length=32)
class Author(models.Model):
  name=models.CharField(max_length=32)
  age=models.IntegerField()
  # 与AuthorDetail建立一对一的关系
  # ad=models.ForeignKey(to="AuthorDetail",to_field="id",on_delete=models.CASCADE,unique=True)
  #OneToOneField 表示创建一对一关系。on_delete=models.CASCADE 表示级联删除。假设a表删除了一条记录，b表也还会删除对应的记录
  ad=models.OneToOneField(to="AuthorDetail",to_field="id",on_delete=models.CASCADE,)

urls.py：

from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
  url(r'^admin/', admin.site.urls),
  # url(r'',views.index),#这一条不能放上面，会造成死循环
  url(r'index/$',views.index),
  url(r'books/add/$',views.add),
  url(r'books/manage/',views.manage),
  url(r'books/delete/(?P<id>\d+)',views.delete),
  url(r'books/modify/(?P<id>\d+)',views.modify),
]

views.py：

from django.shortcuts import render,HttpResponse
from app01 import models
# Create your views here.
def index(request):
  ret=models.Book.objects.all().exists()#True 和 False
  if ret:
    book_list=models.Book.objects.all()
    return render(request,'index.html',{'book_list':book_list})
  else:

    is_pub=request.POST.get("is_pub")
    #插入一条记录

    return HttpResponse(hint)
  return render(request,"add.html")
def manage(request):

  if ret:

    price = request.POST.get("price")
    pub_date = request.POST.get("pub_date")
    publish = request.POST.get("publish")
    is_pub = request.POST.get("is_pub")
    # 更新一条记录
    ret = models.Book.objects.filter(id=id).update(title=title, price=price, publish=publish, pub_date=pub_date,
                            is_pub=is_pub)
    print('更新记录%s'%ret)
    if ret: # 判断返回值为1
      hint = '<script>alert("修改成功");window.location.href="/index/" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" </script>'
