The following example sets the environment variables for connecting to
|
|
PostgreSQL on localhost to the ``postgres`` database and issues a query.
|
|
|
|
.. code:: python
|
|
|
|
import os
|
|
|
|
from sprockets.clients import postgresql
|
|
|
|
os.environ['PGSQL'] = 'postgresql://postgres@localhost:5432/postgres'
|
|
|
|
session = postgresql.Session()
|
|
result = session.query('SELECT 1')
|
|
print(repr(result))
|
|
|
|
|
|
The following example shows how to use the :py:class:`TornadoSession <sprockets.clients.postgresql.TornadoSession>`
|
|
class in a Tornado :py:class:`RequestHandler <tornado.web.RequestHandler>`.
|
|
|
|
.. code:: python
|
|
|
|
import os
|
|
|
|
from tornado import gen
|
|
from sprockets.clients import postgresql
|
|
from tornado import web
|
|
|
|
os.environ['PGSQL_FOO'] = 'postgresql://postgres@localhost:5432/foo'
|
|
|
|
class RequestHandler(web.RequestHandler):
|
|
|
|
def initialize(self):
|
|
self.session = postgresql.TornadoSession('foo')
|
|
|
|
@gen.coroutine
|
|
def get(self, *args, **kwargs):
|
|
result = yield self.session.query('SELECT 1')
|
|
self.write(result.as_dict())
|
|
result.free()
