数据库创建

创建数据库ALU（和alu02/settings.py中一致）

mysql> create database ALU;
Query OK, 1 row affected (0.01 sec)

mysql> 

 

在django中是通过定义models.py来创建数据表的

[root@host-100-100-5-17 alu02]# cat blog/models.py
from django.db import models

class Employee(models.Model):
    name = models.CharField(max_length = 20)
[root@host-100-100-5-17 alu02]# 

 

数据库关联

[root@host-100-100-5-17 alu02]# python manage.py makemigrations
/root/ALU/alu02/alu02/urls.py:21: RemovedInDjango110Warning: Support for string view arguments to url() is deprecated and will be removed in Django 1.10 (got blog.views.index). Pass the callable instead.
  url(r'^blog/index$', 'blog.views.index'),

Migrations for 'blog':
  0001_initial.py:
