Hello,
I want to attach the result of a database SELECT query to the response of
a HTTP GET request.
In twisted.web I've done it this way:
------------------------------
from twisted.web import resource, server, http
from twisted.enterprise import adbapi
class Site(resource.Resource):
...
def render(self, request):
query = "SELECT data FROM test"
self.db.runQuery(query).addCallback(
self._gotData, request).addErrback(
self._dbError, request)
return server.NOT_DONE_YET
Hi,
I've resolved it replacing
return server.NOT_DONE_YET
with
return defer.Deferred()
But I'm not sure is this a best way.
def _gotData(self, results, request):
request.write("%s" % data[0])
request.write(body)
request.finish()
def _dbError(self, failure, request):
request.setResponseCode(http.INTERNAL_SERVER_ERROR)
request.write("Error fetching data.")
request.finish()
------------------------------
What is the best way to perform the same operation in web2? A
web2.server.NOT_DONE_YET constant is not defined.
In other words, how could I return a defer-related response
instead of a simple http.Response object ?
Thank you.
