示例

以下示例演示了使用HandlerMixin与同步Tornado RequestHandler <tornado.web.RequestHandler>一起使用名为postgres的数据库

import os

from sprockets.mixins import postgresql
from tornado import web

os.environ['POSTGRES_HOST'] = 'localhost'
os.environ['POSTGRES_USER'] = 'postgres'
os.environ['POSTGRES_PORT'] = 5432
os.environ['POSTGRES_DBNAME'] = 'postgres'

class PostgresRequestHandler(postgresql.HandlerMixin,
                             web.RequestHandler):

    DBNAME = 'postgres'

    def get(self, *args, **kwargs):
        result = self.foo_session.query('SELECT * FROM bar')
        self.finish({'data': result.items()})

第二个示例演示了使用AsyncHandlerMixin与异步Tornado RequestHandler一起使用名为foo的数据库

import os

from sprockets.mixins import postgresql
from tornado import web

os.environ['FOO_HOST'] = 'localhost'
os.environ['FOO_USER'] = 'postgres'
os.environ['FOO_PORT'] = 5432
os.environ['FOO_DBNAME'] = 'foo'
os.environ['FOO_PASSWORD'] = 'bar'

class FooRequestHandler(postgresql.AsyncHandlerMixin,
                        web.RequestHandler):

    DBNAME = 'foo'

    @web.asynchronous
    def get(self, *args, **kwargs):
        result = yield self.foo_session.query('SELECT * FROM baz')
        self.finish({'data': result.items()})
        result.free()
