You will need to construct an Image (or File) object instance dynamically from your data. The following (untested) python code may be a starting point. As it has to wrap an object i think it will have to be an external method: def getImage(self): from OFS.Image import Image data = self.my_sql_call_to_get_data() im = Image('id_of_image', 'title_of_image', data) # wrap the object so it has a context wrapper im = im.__of__(self) return im Hope this helps. -Matt -- Matt Hamilton matth(a)netsight.co.uk Netsight Internet Solutions, Ltd.

Re: [Zope] DCOracle2 slow - what could be the reason?

> Hi all, > > we have just encountered a bad problem with DCOracle2 performance on large querys compared to anything else. While 40,000 row query done on Perl takes about 1 second - takes it via DCORacle2 on Python more than 20 seconds. I know Chris Withers has done some specific work on the internals of DCOracle2 so may be able to help further.... however is it a performance issue with DCOracle2 itself, or is it more to do with SQL result sets in Zope? Displaying/sorting a 40,000 row SQL result set in ZPT, say, is very expensive. What are you doing to the returned result set in your test? -Matt -- Matt Hamilton matth(a)netsight.co.uk Netsight Internet Solutions, Ltd.

Domain/Subnet/IP Based Authentication/Authorization
by Paul Allen 19 Apr '04

Any new developments on securing ZOPE content based on ip address or domain? I know about the one "solution" (http://plone.org/documentation/howto/HowToDomainIntranet) there but apparently it isn't practical to use. In short I need to control access based on either individual subscriptions (normal zope access) and based on ip address (all users from this lists of subnets are allowed to see content).

DCOracle2 slow - what could be the reason?
by huima＠huima.net 18 Apr '04

18 Apr '04

Hi all, we have just encountered a bad problem with DCOracle2 performance on large querys compared to anything else. While 40,000 row query done on Perl takes about 1 second - takes it via DCORacle2 on Python more than 20 seconds. Any help - including how to debug on what and where DCOracle is consuming the time, would be appreciated. Mikael Gueck ( gumi(a)iki.fi ) can give details on version of DCOracle and Oracle - if that is necessary and if that helps. -huima
