Django 1.10.2 模型数据库操作

首先我的django 版本

>>> django.VERSION
(1, 10, 2, u'final', 0)

setting.py:

DATABASES = {
    'default': {
        'ENGINE':'django.db.backends.mysql',
        'NAME' : 'yyyhl',
        'USER' : 'root',
        'PASSWORD':'',
        'HOST': '127.0.0.1',
    }
}

模型表  models.py

from django.db import models
class Item(models.Model):
    ItemId = models.AutoField(primary_key=True)
    ItemCode = models.CharField(max_length=50)
    ItemName = models.CharField(max_length=50)
    Remark = models.CharField(max_length=200)
 
class Inventory (models.Model):
    InventoryId = models.AutoField(primary_key=True)
    Item = models.ForeignKey(Item, null=False)
    Amount = models.IntegerField(null=True)
 
class InStockBill(models.Model):
    InStockBillId = models.AutoField(primary_key=True)
    InStockBillCode = models.CharField(max_length=40)
    InStockDate = models.DateTimeField(null=True)
    Operator = models.CharField(max_length=40)
    Item = models.ForeignKey(Item, null=False)
    Amount = models.IntegerField(null=True)

接下来检查

#我新建的模块名字是 app_one
#验证模型是否有效
命令：python manage.py check
System check identified no issues (0 silenced).
 
 #用来检测数据库变更和生成数据库迁移文件
命令：python manage.py makemigrations 模块名字
 
#用来迁移数据库
python manage.py migrate
 
# 用来把数据库迁移文件转换成数据库语言
python manage.py sqlmigrate app_one 0001
