1.多对多关系数据访问
models.py设置
from django.db import models # Create your models here. sex_choices=( ('f','famale'),('m','male') ) class User(models.Model): name = models.CharField(max_length=30) sex=models.CharField(max_length=1,choices=sex_choices) def __unicode__(self): return self.name class Author(models.Model): name=models.CharField(max_length=30) def __unicode__(self): return self.name class Book (models.Model): name = models.CharField(max_length=30) author=models.ManyToManyField(Author) def __unicode__(self): return self.name
views.py中调用
def index1(req): aus = Author.objects.all() books = Book.objects.all() t= loader.get_template('index1.html') c=Context({'aus':aus,'books':books}) return HttpResponse(t.render(c))
templates中模板的设置
<body> {% for book in books %} <h1>书籍:{{book}}<br></h1> {% for au in book.author.all %} 作者: {{au}} <br/> {%endfor%} {% endfor%} </body>
输出的结果:
