1、python manage.py startup yourapp 2 from django.db import models models.CharField max_length models.URLField models.EmailField models.ForeignKey models.DateField 3 python manage.py validate obj.save() Obj.objects.all() Obj.objects.create(xx=,x) 4 def __unicode(self): return self.name from django.db import models

**def __unicode__(self):**
    **return self.name**

5 Obj.objects.filter(name='xxx') name__contains="aa" Obj.objects.get(name="xxx") Obj.objects.order_by("name","") Obj.objects.order_by("-name") 逆序 6 class Meta: ordering=['name']

class Publisher(models.Model): name = models.CharField(max_length=30) address = models.CharField(max_length=50) city = models.CharField(max_length=60) state_province = models.CharField(max_length=30) country = models.CharField(max_length=50) website = models.URLField()

def __unicode__(self):
    return self.name

**class Meta:**
    **ordering = ['name']**

7 Publisher.objects.order_by('name')[0] 但是不支持负索引 8 update: Publisher.objects.filter(id=52).update(name='Apress Publishing') 9 delete: obj.delete()
