Requirements
|
|

Example
|
|
-------
|
|
The following example demonstrates using the ``HandlerMixin`` with a
|
|
synchronous Tornado ``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 ``AsyncHandlerMixin`` with an
|
|
asynchronous Tornado ``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()
