ORM for sqlite3 like Django ORM.
from datetime import datetime
import database
db = database.Sqlite('blog.db')
class Post(db.Model):
title = database.CharField(20)
content = database.TextField()
created_time = database.DateTimeField()
db.create_table(Post)
post = Post(title='post title', content='post content', created_time=datetime.now())
post.save()
post.id, post.title, post.content
Out: (5, 'post title', 'post content', datetime.datetime(2016, 1, 6, 17, 25, 37, 342000))
print Post.select().where(id=5).all()
Out: [<Post post title>]
The ManyToManyField just like Django ManyToManyField:
class Tag(db.Model):
name = database.CharField(50)
posts = database.ManyToManyField(Post)
When create table from class Tag, ORM will auto-create a table post_tag which referenced Post and Tag.
We can add tag to the post like this:
tag = Tag(name='tag')
tag.save()
post.tags.add(tag)
post.tags.all()
Out: [<Tag tag>]
