Hi there,
Is there a standard way to pass extra arguments to the underlying
DB-API's connect(..) function via the URL?
For example, MySQLdb's connect takes a parameter called init_command.
I need this to set the MySQL driver to return UTF-8 encoded strings
correctly. The SA way of defining a custom creator function and a
user-provided Pool class does not fit very well to my TurboGears
project (to say the least).
The dialect's constructor receives the url query-part as a dict. I
modified the MySQL dialect a little so that it picks 'init_command'
out of the list and stores them in a member variable. I then use these
in "create_connect_args".
The start of MySQLDialect then looks like this:
class MySQLDialect(ansisql.ANSIDialect):
def __init__(self, module = None, **kwargs):
if module is None:
self.module = mysql
else:
self.module = module
dbapiargs = ('init_command',) # add more choices here
self.extraargs = {}
for arg in dbapiargs:
if arg in kwargs:
self.extraargs[arg] = kwargs.pop(arg)
ansisql.ANSIDialect.__init__(self, **kwargs)
def create_connect_args(self, url):
opts = self.extraargs.copy()
opts.update(url.translate_connect_args(['host', 'db', 'user',
'passwd', 'port']))
return [[], opts]
Then I can use an url like
"mysql://user:[EMAIL
PROTECTED]/database?init_command=set%20character%20set%20utf8".
I know this is not the proper way of doing this, but it gets my idea across.
Is there any way something like this would be implemented in SA?
