Question

我有以下型号。

from django.db import models

class Client(models.Model):
    postcode = models.CharField(max_length=10)  
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    address = models.TextField(blank=True)
    phone = models.IntegerField(blank=True)
    email = models.EmailField(blank=True)
    url = models.URLField(blank=True)
    client_since = models.DateTimeField('Client Since')

    def __unicode__(self):
        return self.first_name

def client_since(self):
    return self.client_since.date() == datetime.date.today()

class Contractor(models.Model):
   postcode = models.CharField(max_length=10)   
   first_name = models.CharField(max_length=100)
   last_name = models.CharField(max_length=100)
   address = models.TextField(blank=True)
   phone = models.IntegerField(blank=True)
   email = models.EmailField(blank=True)
   contractor_since = models.DateTimeField('Contractor Since')

   def __unicode__(self):
       return self.first_name

   def contractor_since(self):
       return self.contractor_since.date() == datetime.date.today()

我运行'python manage.py validate'给我 - 找到0个错误

然后我运行'python manage.py sql“appname”然后我会看到我的表......

BEGIN;
CREATE TABLE "schedule_client" (
    "id" integer NOT NULL PRIMARY KEY,
    "postcode" varchar(10) NOT NULL,
    "first_name" varchar(100) NOT NULL,
    "last_name" varchar(100) NOT NULL,
    "address" text NOT NULL,
    "phone" integer NOT NULL,
    "email" varchar(75) NOT NULL,
    "url" varchar(200) NOT NULL,
    "client_since" datetime NOT NULL
 )
 ;
 CREATE TABLE "schedule_contractor" (
     "id" integer NOT NULL PRIMARY KEY,
     "postcode" varchar(10) NOT NULL,
     "first_name" varchar(100) NOT NULL,
     "last_name" varchar(100) NOT NULL,
     "address" text NOT NULL,
     "phone" integer NOT NULL,
     "email" varchar(75) NOT NULL
 )
 ;
 COMMIT;

但我没有在承包商表中看到“contracor_since ...正在创建数据库字段???我尝试了几次，我在OS X豹子上使用django 1.1.1。

我做错了什么？

您正在使用相同的名称通过函数定义来遮蔽模型属性。尝试更改函数名称或模型属性（contractor_since）。

django模型和sqlite数据库创建错误
