Flask 在 Flask 中使用 MongoKit

from flask import Flask
from mongokit import Connection, Document

# configuration
MONGODB_HOST = 'localhost'
MONGODB_PORT = 27017

# create the little application object
app = Flask(__name__)
app.config.from_object(__name__)

# connect to the database
connection = Connection(app.config['MONGODB_HOST'],
                        app.config['MONGODB_PORT'])

def max_length(length):
    def validate(value):
        if len(value) <= length:
            return True
        raise Exception('%s must be at most %s characters long' % length)
    return validate

class User(Document):
    structure = {
        'name': unicode,
        'email': unicode,
    }
    validators = {
        'name': max_length(50),
        'email': max_length(120)
    }
    use_dot_notation = True
    def __repr__(self):
        return '<User %r>' % (self.name)

# register the User document with our current connection
connection.register([User])

>>> from yourapplication.database import connection
>>> from yourapplication.models import User
>>> collection = connection['test'].users
>>> user = collection.User()
>>> user['name'] = u'admin'
>>> user['email'] = u'admin@localhost'
>>> user.save()

>>> list(collection.User.find())
[<User u'admin'>]
>>> collection.User.find_one({'name': u'admin'})
<User u'admin'>

from MongoKit import Connection

connection = Connection()

>>> collection = connection['test'].users
>>> user = {'name': u'admin', 'email': u'admin@localhost'}
>>> collection.insert(user)

>>> list(collection.find())
[{u'_id': ObjectId('4c271729e13823182f000000'), u'name': u'admin', u'email': u'admin@localhost'}]
>>> collection.find_one({'name': u'admin'})
{u'_id': ObjectId('4c271729e13823182f000000'), u'name': u'admin', u'email': u'admin@localhost'}

>>> r = collection.find_one({'name': u'admin'})

u'admin@localhost'
