========
|
|
The following example demonstrates using the
|
|
:py:class:`HandlerMixin <sprockets.mixins.postgresql.HandlerMixin>` with a
|
|
synchronous Tornado :py:class:`RequestHandler <tornado.web.RequestHandler>` for a database
|
|
named ``postgres``:
|
|
|
|
.. code:: python
|
|
|
|
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()})
|
|
|
|
The second example demonstrates using the
|
|
:py:class:`AsyncHandlerMixin <sprockets.mixins.postgresql.AsyncHandlerMixin>`
|
|
with an asynchronous Tornado :py:class:`RequestHandler <tornado.web.RequestHandler>`
|
|
for a database named ``foo``:
|
|
|
|
.. code:: python
|
|
|
|
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.HandlerMixin,
|
|
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()
