django中在代码中建表，插入数据

1在models.py中修改

from django.db importmodels

 

# Create your modelshere.

classHost(models.Model):

        hostname =models.CharField(max_length=30)

        address =models.CharField(max_length=17)

2 同步数据库

[root@iZ23wgy1r3bZweb2]# python manage.py makemigrations

Migrations for 'blog':

  0001_initial.py:

    - Create model Host

[root@iZ23wgy1r3bZweb2]# python manage.py migrate

3 创建对象

python manage.py shell

 

from blog.models importHost

Host.objects.create(hostname='host1',address='192.168.1.101')

 

数据库查数据

sqlite> select *from blog_host;

1|host1|192.168.1.101

第二种插数据的方法

host = Host()

host.hostname='host2'

host.address='192.168.1.102'

host.save()
