Django数据模型的创建

1,创建数据库模型

编辑models.py

from django.db import models

class Article(models.Model):
    title = models.CharField("标题", max_length=30)
    writer = models.CharField("作者", max_length=10)
    content = models.TextField()
    create_date = models.DateField(auto_now_add=True)
    update_date = models.DateField(auto_now=True)
    is_show = models.BooleanField(default=False)

    class Meta:
        db_table = ‘article‘

    def __str__(self):
        return self.title

具体规则见:https://docs.djangoproject.com/en/1.11/topics/db/models/

2,修改setting.py

加上我们的app

3,更新数据库

把新数据迁移工具 (migrations)

$ python manage.py makemigrations --name changed_my_model your_app_label

把新数据迁移到数据库

$ python manage.py migrate
